DNDC is a computer simulation model of carbon and nitrogen biogeochemistry in agro-ecosystems. It is used in agricultural tri-dimensional pollution control widely. Learning from abroad advanced technologies and research methods, we have developed an agricultural tri-dimensional pollution data submission and management platform based on DNDC model. The platform is very important for sharing and building our agricultural carbon and nitrogen chain database. 1 Introduction DNDC

The model can be used for predicting crop growth, soil temperature and moisture regimes, soil carbon dynamics, nitrogen leaching, and emissions of trace gases including nitrous oxide (N 2 O), nitric oxide (NO), dinitrogen (N 2 ), ammonia (NH 3 ), methane (CH 4 ) and carbon dioxide (CO 2 ). Studying on carbon and nitrogen chain in agricultural tri-dimensional pollution [1] and blocking carbon and nitrogen pollution sources is very important for prevention and treatment agricultural carbon and nitrogen pollution [2]. Development DNDC [3] model needed data management system can undoubtedly provides important scientific support for our country agriculture carbon and nitrogen emission reduction [4] database construction and data sharing. Study and develop a data submission, management and supporting DNDC model platform for every level user in agriculture tri-dimensional [5] preventive treatment centre. Data submission and management module provides data management interface for administrators and is in favor of adjusting agriculture tri-dimensional pollution data. Assistant DNDC [6] model module can read out data from DNDC database for users and create txt files and also imports DNDC model results to database according to user' willing. 2 Platform Main Functions This platform is made up of distributed data submission and management module, submitted data centralized management module and assistant DNDC module. The functions of platform are shown in figure 1. Abstract. DNDC is a computer simulation model of carbon and nitrogen biogeochemistry in agro-ecosystems.
