摘　　要：在分析毛乌素沙地环境背景与系统结构缺陷和功能缺陷的基础上,按照沙地农业生态系统模式优化必须从产业结构调整出发进行系统功能整合的思路,以沙地生态恢复、生态工程、资源高效利用及农业产业互补理论为指导,提出毛乌素沙地农业生态系统功能的有效化,必须协调处理好系统内的农业与畜牧业、农业与林业、农业与能源开发工业等的关系,构建防护型生态结构、节水型种植结构、稳定型畜牧结构和效益型农业产业结构为中心内容的沙地脆弱性农业生态系统优化模式体系。并指出注重系统模式之间互补、协调与整合尤为重要。Optimization models of agricultural ecosystem have played an important role in the smooth running of fragile agricultural ecosystem. Based on an analysis of the environmental background and systematic limitation of Mu Us sandland in the northern part of China, a new point of view was proposed for the model optimization of agricultural ecosystem on sandland. Namely, the industrial structure has to be modified so as to make a functional integration of different parts of the whole system. According to the theories of ecological recovery, ecological engineering, the high efficient utilization of resources and complementary industry, and to design the ecology structure of defense, the planting structure of saving water, the pasturage structure of stabilization and industrial structure of benefit when to pay attention to functional availability of agricultural ecosystem, which is feasible on condition that reasonably dealing with the relationships of agriculture and stockbreeding, forestry, energy-industry, and so on. It is important that ecosystem models can be harmonized, integrated and coupled efficiently. We are looking forward to giving academic gist and technical support at model optimization for similar agricultural ecosystem in the adversity.
