Development and Application of Decision Support System for Agro-Technology Transfer DSSAT under Water Resources Management

The Cropping System Model (CMS) simulates growth, development and yield of a crop growing on a uniform area of land under prescribed or simulated management as well as the changes in soil water, carbon, and nitrogen that take place under the cropping system over time. Decision Support System for Agro-technology Transfer DSSAT is one of many cropping system models and has been relatively widely applied. In this paper, the development history, the system structure, and the application field of the model system are summarized, and the principle and mechanism of the model to simulate the soil-water balance in the study of water resources management and the representative study results obtained by the scholars in China are analyzed in detail, so as to provide references for relevant studies and applications.
