Abstract:

SALUS is a famous system approach to land use sustainability model. This paper realized a crop growth simulation system based on WebGIS integrated with SALUS. We elaborated the database and the correlative function module integration method in details. The spatial data processing and simulation results visualization ability of SALUS model can be improved in this system. Using this system, users can master various factors affecting crop yield clearly, like soil, weather, irrigation quantity, fertilizer quantity, etc. Thus, the paper provided scientific basis for management measures of increasing income, and also a related integration program, so as to supply technical support for the construction of crop growth simulation system based on WebGIS.

Key words: crop growth simulation system, SALUS, WebGIS, system integration

摘要：

SALUS是较为著名的土地可持续使用系统模型，实现了一种基于WebGIS整合SALUS的作物生长仿真系统。详细阐述了数据库和相关功能模块的整合方法，改善了SALUS模型在空间数据处理与仿真结果视觉化的能力。可以让使用者清晰的掌握土壤、天气、灌溉量、施肥量等多种因素对农作物产量的影响，为农作物实施相关的增收管理措施提供了一定的科学依据。并提出了相应的整合方案为实际构建基于WebGIS的作物生长仿真系统提供了一定的技术支撑。
