Soil Conservation Service Spatiotemporal Variability and Its Driving Mechanism on the Guizhou Plateau, China

Linan Niu, Quanqin Shao
<span title="2020-07-08">2020</span> <i title="MDPI AG"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/kay2tsbijbawliu45dnhvyvgsq" style="color: black;">Remote Sensing</a> </i> &nbsp;
The Guizhou Plateau has an extremely fragile ecological environment with prominent soil and water losses. Since 2000, conservation policies and ecological restoration projects, e.g., the Grain for Green Project (GGP), have been implemented on the Guizhou Plateau to control soil/water losses which have achieved notable accomplishments. Using the Revised Universal Soil Loss Equation (RUSLE) to estimate the soil conservation service (SCS) on the Guizhou Plateau, this study analyzed the dynamic
more &raquo; ... acteristics of its spatiotemporal variation based on multiyear (2000–2018) meteorological and remote sensing data to determine its driving mechanisms. Residual analysis of the meteorological and remote sensing data was used to evaluate the effect of anthropogenic activities. Results showed a clear upward trend (1.39 t ha−1 yr−1) of SCS on the Guizhou Plateau during 2000–2018, and areas with a highly improved positive effect on SCS were distributed primarily in karst landform regions. Precipitation and vegetation fractional coverage (VFC) were found to be positively correlated with SCS on the Guizhou Plateau. Specifically, the highest proportion of significant positive correlation between precipitation and SCS was related to the Wildlife Conservation Nature Reserve (WCNR), and the highest proportion of significant positive correlation between VFC and SCS was related to the GGP, i.e., 76.59% and 53.02%, respectively. Residual analysis revealed a significant positive role of anthropogenic activity on SCS improvement via ecological engineering in areas with a poor ecological background, e.g., the GGP in western areas where the ecological environment is fragile and the problem of water/soil loss is serious. In areas with a more robust ecological background, e.g., the engineering area of the WCNR, the effect of anthropogenic activity has had a largely negative effect on SCS. The findings of this study could make an important contribution to the development of ecological management projects and the work to control soil/water losses on the Guizhou Plateau.

Surveying Wild Animals from Satellites, Manned Aircraft and Unmanned Aerial Systems (UASs): A Review

Dongliang Wang, Quanqin Shao, Huanyin Yue
<span title="2019-06-01">2019</span> <i title="MDPI AG"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/kay2tsbijbawliu45dnhvyvgsq" style="color: black;">Remote Sensing</a> </i> &nbsp;
This article reviews studies regarding wild animal surveys based on multiple platforms, including satellites, manned aircraft, and unmanned aircraft systems (UASs), and focuses on the data used, animal detection methods, and their accuracies. We also discuss the advantages and limitations of each type of remote sensing data and highlight some new research opportunities and challenges. Submeter very-high-resolution (VHR) spaceborne imagery has potential in modeling the population dynamics of
more &raquo; ... e (>0.6 m) wild animals at large spatial and temporal scales, but has difficulty discerning small (<0.6 m) animals at the species level, although high-resolution commercial satellites, such as WorldView-3 and -4, have been able to collect images with a ground resolution of up to 0.31 m in panchromatic mode. This situation will not change unless the satellite image resolution is greatly improved in the future. Manned aerial surveys have long been employed to capture the centimeter-scale images required for animal censuses over large areas. However, such aerial surveys are costly to implement in small areas and can cause significant disturbances to wild animals because of their noise. In contrast, UAS surveys are seen as a safe, convenient and less expensive alternative to ground-based and conventional manned aerial surveys, but most UASs can cover only small areas. The proposed use of UAS imagery in combination with VHR satellite imagery would produce critical population data for large wild animal species and colonies over large areas. The development of software systems for automatically producing image mosaics and recognizing wild animals will further improve survey efficiency.

Modeling Aboveground Biomass in Hulunber Grassland Ecosystem by Using Unmanned Aerial Vehicle Discrete Lidar

Dongliang Wang, Xiaoping Xin, Quanqin Shao, Matthew Brolly, Zhiliang Zhu, Jin Chen
<span title="2017-01-19">2017</span> <i title="MDPI AG"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/taedaf6aozg7vitz5dpgkojane" style="color: black;">Sensors</a> </i> &nbsp;
Accurate canopy structure datasets, including canopy height and fractional cover, are required to monitor aboveground biomass as well as to provide validation data for satellite remote sensing products. In this study, the ability of an unmanned aerial vehicle (UAV) discrete light detection and ranging (lidar) was investigated for modeling both the canopy height and fractional cover in Hulunber grassland ecosystem. The extracted mean canopy height, maximum canopy height, and fractional cover
more &raquo; ... used to estimate the aboveground biomass. The influences of flight height on lidar estimates were also analyzed. The main findings are: (1) the lidar-derived mean canopy height is the most reasonable predictor of aboveground biomass (R 2 = 0.340, root-mean-square error (RMSE) = 81.89 g·m −2 , and relative error of 14.1%). The improvement of multiple regressions to the R 2 and RMSE values is unobvious when adding fractional cover in the regression since the correlation between mean canopy height and fractional cover is high; (2) Flight height has a pronounced effect on the derived fractional cover and details of the lidar data, but the effect is insignificant on the derived canopy height when the flight height is within the range (<100 m). These findings are helpful for modeling stable regressions to estimate grassland biomass using lidar returns.

Improving Carbon Mitigation Potential through Grassland Ecosystem Restoration under Climatic Change in Northeastern Tibetan Plateau

Lin Huang, Xinliang Xu, Quanqin Shao, Jiyuan Liu

To protect the water tower's ecosystem environment and conserve biodiversity, China has been implementing a huge payment program for ecosystem services in the three rivers source region. We explored here the dynamics of grassland degradation and restoration from 1990 to 2012 and its relationships with climate mitigation in the TRSR to provide a definite answer as to the forcing and response of grassland degradation and restoration to climate change. Then we estimated its potential of climate
more &raquo; ... igation benefits to address the question of whether ecological restoration could be effective in reversing the decline of ecosystem carbon mitigation service. The trend of average annual temperature and precipitation observed by meteorological stations were approximately increased. Compared before and after 2004, the area of grassland degradation was increased slightly. However, nearly one-third of degraded grassland showed improvement, and the grassland vegetation coverage showed significant increase. Comparing current grassland vegetation coverage with healthy vegetation cover with the same grass type, nearly half of the area still needs to further restore vegetation cover. The grassland degradation resulted in significant carbon emissions, but the restoration to its healthy status has been estimated to be technical mitigation potential.

A spatial system dynamic model for regional desertification simulation – A case study of Ordos, China

Duanyang Xu, Alin Song, Hefeng Tong, Hongyan Ren, Yunfeng Hu, Quanqin Shao
<span title="">2016</span> <i title="Elsevier BV"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/irxlz6wefjcmnddydjot2v3uii" style="color: black;">Environmental Modelling &amp; Software</a> </i> &nbsp;
A spatial system dynamic (SSD) model for simulating desertification was developed by integrating climate, soil water, population, economy, pasturage, and land use. Net Primary Production (NPP) was selected as an intermediate variable to measure the impacts of driving forces and desertification grades. Ordos in China was selected to test the model. Ten scenarios were designed to simulate desertification dynamics in Ordos from 2011 to 2030. The results showed that the SSD model was reliable, and
more &raquo; ... he overall accuracy of desertification degree was approximately 83%. Climate factors had relatively higher sensitivities than other parameters. Although humid climate and sustainable development strategy would reduce desertified land area and desertification degree before 2025, the rapid increase in pasturage pressure would offset this trend. Arid climate and unsustainable development strategy would accelerate desertification expansion. For local government, it is necessary to persist in the present desertification prevention policy and completely banned grazing after 2025.

Intra-annual variability of satellite observed surface albedo associated with typical land cover types in China

Zhengjia Liu, Quanqin Shao, Jian Tao, Wenfeng Chi
<span title="2014-12-06">2014</span> <i title="Springer Nature"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/gg4i5n6ffnbb7jsuzsmjpf3f2i" style="color: black;">Journal of Geographical Sciences</a> </i> &nbsp;
Surface albedo is a primary causative variable associated with the process of surface energy exchange. Numerous studies have examined diurnal variation of surface albedo at a regional scale; however, few studies have analyzed the intra-annual variations of surface albedo in concurrence with different land cover types. In this study, we amalgamated surface albedo product data (MCD43) from 2001 to 2008, land-use data (in 2000 and 2008) and land cover data (in 2000); quantitative analyses of
more &raquo; ... e albedo variation pertaining to diverse land cover types and the effect of the presence/absence of ground snow were undertaken. Results indicate that intra-annual surface albedo values exhibit flat Gaussian or triangular distributions depending upon land cover types. During snow-free periods, satellite observed surface albedo associated with the non-growing season was lower than that associated with the growing season. Satellite observed surface albedo during the presence of ground snow period was 2-4 times higher than that observed during snow-free periods. Surface albedo reference values in typical land cover types have been calculated; notably, grassland, cropland and built-up land were associated with higher surface albedo reference values than barren while ground snow was present. Irrespective of land cover types, the lowest surface albedo reference values were associated with forested areas. Proposed reference values may prove extremely useful in diverse research areas, including ecological modeling, land surface process modeling and radiation energy balance applications.

To better understand variation in response of components of ecosystem evapotranspiration (ET) to grassland use differences, we selected three typical land use patterns in a temperate steppe area: grazed steppe (G), steppe with grazers excluded (GE), and steppe cultivated to cropland (C). ET was divided into its components evaporation (E) and canopy transpiration (T) using herbicide and a chamber attached to a portable infrared gas analyzer (Li-6400). The results indicated that daily water
more &raquo; ... ption by ET in G was 3.30 kg m−2d−1; compared with G, ET increased significantly in GE at 13.4% and showed a trend of 6.73% increase in C. Daily water consumption by E increased 24.3% in GE relative to G, and C showed 20.2% more than GE. At 0.46, E/ET in C was significantly higher than G at 0.35. Air temperature and the vapor pressure deficit were closely correlated with variation in diurnal ET, E, and T. The leaf area index (LAI) was also positively correlated with daily ET and E varied among grassland use patterns and explained variation in E/ET (81%). Thus, variation in LAI strongly influences the overall magnitude of ecosystem ET and the composition of its components under different grassland use patterns.

摘 要: 在 3S 技术支持下, 结合景观格局定量分析方法, 基于 30 m 分辨率的土地利用/覆被数据, 对中国退牧还草 工程区 2000-2010 年土地利用/覆被时空分布特征进行研究。通过利用土地利用转移矩阵和动态度来判定土地利 用变化的速度和区域差异, 并在斑块类型和景观水平上分析研究区景观格局特征, 探讨土地利用格局变化的生态 效应。结果表明: ①近 10 年来, 研究区土地利用/覆被类型以草地和其他类用地为主, 整体内部结构稳定少动。草 地变化面积仅占 2000 年草地总面积的 0.37%; 林地、 湿地、 耕地和人工表面的面积均有所增加; 其他类用地面积有 所减少。②全区土地综合动态度均小于 0.1%, 土地利用/覆被变幅较小, 除人工表面较活跃外, 其他各类型变化相 对缓慢, 且各省土地利用区域差异较小。③研究区内景观基质未发生改变, 区域景观破碎度递减, 景观多样性水平 上升, 景观聚集度和连续性微弱下降, 景观整体保持较完整态势。退牧还草工程的实施使土地利用/覆被结构和景 观格局均得以优化。 关 键 词: 土地利用/覆被; 景观格局; 动态变化; 退牧还草工程;
more &raquo; ... 国 1 引言 中国拥有各类天然草地近 4 亿 hm 2 , 居世界第 二位, 占国土面积的 41.7%(苏大学, 1996)。草地是 中国面积最大的陆地生态系统和绿色生态屏障, 具 有重要的生态服务功能, 起着调节气候、 涵养水源、 防风固沙、 保持水土、 改良土壤、 增肥地力、 净化空 气、 美化环境等作用(张苏琼等, 2006)。草地也是畜 牧业发展的重要物质基础和牧区农牧民赖以生存 和发展的基本生活生产资料(孙启忠等, 2011), 对中 国畜牧业生产和经济社会可持续发展都具有重要 作用。 长期以来, 在自然因素和人为因素的综合作用 下, 中国的草地资源遭受到了严重的破坏, 有 90% 的草地存在着不同程度的退化, 严重退化面积达 480 万 hm 2 之多(何昌茂, 2000), 特别是近几十年因 人类活动的强烈影响, 草地超载、 草地退化、 沙漠化 尤为明显, 且每年以草地可利用面积 2%的速度加 速退化, 半干旱地区天然草地退化面积已占 75%9 5%(王庆锁等, 2004)。由于草地生态环境的不断 恶化, 草地生产力下降, 草地生态危机引发的生态 问题已经影响到中国的可持续发展及生态安全。 为遏制西部地区天然草地加速退化的趋势, 促进草 地生态修复, 党中央、 国务院作出重大决策, 于 2003 年正式启动退牧还草工程。退牧还草工程实施后, 工程区内草地植被较工程区外和实施前均有明显 改善。根据 2010 年农业部监测结果, 工程区平均植 被盖度为 71%, 比非工程区高出 12%; 草群高度、 产 草量和可食鲜草产量分别比非工程区高出 37.9%、 43.9%、 49.1%(朱军强, 2011)。生物多样性、 群落均

<span title="2019-11-15">2019</span> <i title="MDPI AG"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/oglosmy3gbhuzobyjit4qalakq" style="color: black;">Sustainability</a> </i> &nbsp;
Frequent snowfall and low temperatures led to a considerable snow disaster in some areas of China's Three-River Headwaters Region (TRHR) in Qinghai province in the spring of 2019, exerting a considerably negative influence on animal husbandry production in local grasslands. Based on a model of snow disaster classification and quantitative estimations of disaster-stricken animal husbandry, we propose a comprehensive disaster resistance capability index (CDRCI) using remote sensing, ground
more &raquo; ... ing, and statistical investigations. With a comprehensive assessment of the space distribution and the magnitude of snow disasters, combined with a quantitative determination of disaster-stricken animal husbandry, the proposed CDRCI calculates how grassland animal husbandry is affected by snow disasters in different counties of the TRHR. The results indicate that approximately 2.31 million sheep and yaks were affected by moderate to severe snow disasters in the TRHR, accounting for 78.3% of the total livestock in the affected region. Of these affected livestock, approximately 1.54 million sheep and yaks were specifically affected by severe snow disasters, accounting for 52.1% of the total number of livestock. The CDRCIs for grassland animal husbandry in both Yushu and were moderate, being higher for the former than for the latter. We confirmed that the proposed CDRCI can accurately evaluate the magnitude of snow disasters in terms of how they affect grassland animal husbandry. The CDRCI is a way of relating the number of animal deaths to spatial disaster prevention and resistance. We expect that this research will provide important theoretical support for formulating snow disaster resistance policy, for example for increasing the construction of grassland animal husbandry infrastructure as well as providing greater stored forage material.
