Mapping Soil Organic Matter and Analyzing the Prediction Accuracy of Typical Cropland Soil Types on the Northern Songnen Plain

Meiwei Zhang, Huanjun Liu, Meinan Zhang, Haoxuan Yang, Yuanliang Jin, Yu Han, Haitao Tang, Xiaohan Zhang, Xinle Zhang
2021 Remote Sensing  
The advantage of using single soil type data versus the total dataset was evaluated, and SOM maps were drawn for the northern Songnen Plain.  ...  However, few studies have analyzed the changing trends in multi-period SOM prediction accuracies for single cropland soil types and mapped their spatial SOM patterns.  ...  Acknowledgments: We thank AJE (https://www.aje.com/, accessed on 11 November 2021) for its linguistic assistance during the preparation of this manuscript.  ...

Remote Sensing of Soil Alkalinity and Salinity in the Wuyu'er-Shuangyang River Basin, Northeast China

Lin Bai, Cuizhen Wang, Shuying Zang, Yuhong Zhang, Qiannan Hao, Yuexiang Wu
2016 Remote Sensing  
The Songnen Plain of the Northeast China is one of the three largest soda saline-alkali regions worldwide.  ...  Spatial distributions of soil alkalinity and salinity were mapped from the OLI image with the RMSE of 1.01 and 0.64 dS/m, respectively.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...

The Variations of Satellite-Based Ecosystem Water Use and Carbon Use Efficiency and Their Linkages with Climate and Human Drivers in the Songnen Plain, China

Bo Li, Fang Huang, Shuai Chang, Ning Sun
2019 Advances in Meteorology  
In this study, ecosystem-level WUE and CUE variations in the Songnen Plain (SNP), Northeast China, during 2001–2015, were investigated using Moderate Resolution Imaging Spectroradiometer (MODIS) satellite  ...  Annual precipitation and relative humidity had positive influences on WUE and CUE in more than 60% of the study area.  ...  Soils are fertile, with black soil, meadow soil, and chernozem being widely distributed in this plain.  ...

2019 Geoscientific Model Development  
Moreover, further study and measurement of sandblasting efficiency of different soil types and locations should be conducted to improve the accuracy of estimated vertical dust fluxes in air quality models  ...  Although these models reproduced the spatial pattern of the dust plume, there were large discrepancies between predicted and observed PM10 concentrations in each model.  ...  The authors are grateful to the website of national air quality history database for collecting and maintaining the ground-based air quality data and appreciate NASA for providing the MODIS and CALIPSO  ...

2014 Environmental science and pollution research international  
The corresponding samples were collected and analyzed on a large regional scale. The total input fluxes show obvious spatial variability among different regions.  ...  The results indicate that Hg is the element of prior concern for agricultural soil, followed by Cd and As, and other heavy metal elements represent little threat to the environment in the study area.  ...  Acknowledgements This study was supported by the project of China Geological Survey Study on Evaluation System and Integration of the Eco-geochemical Assessment for the Agricultural Ecosystem of China  ...
