基于Web服务和GIS的作物生长模拟系统及应用

Crop growth simulation system based on web services and GIS and its application

鉴于Web服务技术的优越性以及当前作物模拟模型共享存在的困难,该文提出了基于Web服务和GIS的作物生长模拟系统架构;实现了作物模拟生长Web服务,开发了"YIELD作物产量模拟系统",并进行了实际应用。实践表明:将Web服务应用于作物生长模拟切实可行,有利于系统集成和作物模拟模型的全社会范围内的共享。同时,也为其它农业信息系统的集成提供了参考。

Based on the superiority of web services technology and the difficulty in share of the crop simulation models, the author brings forward an integrated system framework established on the basis of web services and GIS. The author also accomplished the web service to simulate crop yield and developed a system under the framework successfully, which has been applied into the Yangou basin in China. The practice shows that it is feasible to put the web services into the use of crop simulation, which is in favor of system integration and share of the crop models for the whole society.
