通过系统集成 ,将农业生态经济分区、农牧系统综合评价等应用模型与 GIS进行集成 ,构建了农区农牧系统生产力综合评价系统 .采用该系统把长江三角洲的生态经济划分为 3个区 :北部经济次发达区 ( I区 )、中部经济发达区 ( II区 )和南部经济次发达区 ( III区 ) .同时 ,对长江三角洲农牧系统生产力进行综合分析 ,发现长江三角洲农牧系统的生产力具有大幅度提高的潜力 ,并存在显著的空间梯度差异 Through the system integration, this paper integrates the application models of agricultural eco-economic zoning and the comprehensive evaluation of farming and animal husbandry system with GIS, and builds a comprehensive evaluation system of productivity of agriculture and animal husbandry in rural areas. The system uses the system to divide the ecological economy of the Yangtze River Delta into three districts: In the meantime, a comprehensive analysis of the productivity of farming and animal husbandry systems in the Yangtze River Delta shows that the productivity of the farming and pasturing systems in the Yangtze River Delta Has the potential to greatly improve, and there is a significant spatial gradient difference
