摘要
将地理信息系统技术作为平台 ,研究和设计了流域农林生态经济系统结构优化空间决策支持系统 ,该系统以遥感数据为基础 ,集成了水库营养盐负荷 -浓度响应关系模型、农业非点源污染模拟模型和农林土地利用优化配置模型等 ,集成后模型与 GIS在结构上联结成为一个系统 ,该系统具有完整的界面 ,用户可以同时在不同功能模块之间随意切换 。
A spatial structure optimization decision support system for agro forestry ecological and economic system based on Geographical Information System (GIS) was studied in this paper.The system integrated GIS with pollutant loading and its response of the receptor of the reservoir water,Agricultural Non Point Source (AGNPS) model and linear programming.The models were included in the spatial decision support system with a unique platform and common interfaces.So the proposed system largely improves data manipulation for input file creation,simulation control and interpretation of results.
