On the basis of the metioned above, in the mass, the thesis amalyzes the ecological problems that Wuzhong has and the reasons that result then in , ecological construction acheivments and it"s consumable affecs ;then in detail and using the way combined fix quatity with quality , analyzes the condition, degree, mechanism, processof ecological caustic of various regions and kinds of ecological systems in Wuzzhong, juging the feasibility of restore and reconstruction of them. The paper indicates, as a whole ,the degree of eological caustic of the region is relative severity, but the diffefences between the plain region and the mountains region are very obvious, and all of them can be retored and rconstructed, wich has been proved by theory and practices. According to the conclutions and combining them with the mature theory ecological fumction dividings and the condition of Wuzhong"s mature and society , the study divides the region into seven ecological functional areas. On basis of the ecological construction strategic targets presented by the governments of the country and Ningxia,Wuzhong and the caustic condions of different ecological system in defferent areas, the author design the models of ecological restoration and reconstruction for the different ecological areas and how to use them.

在此基础上，从宏观上分析了吴忠目前存在的主要生态问题和形成原因、生态建设成就与成果自耗因素，接着着重从微观上对吴忠各地的生态致损情况、各类生态系统的受损度、受损机理和过程、生态恢复与重建的可行性进行定量和定性分析判断，指出从整体上看该区域生态受损比较严重，但存在着明显的山川二元结构，其恢复与重建在理论和实践上均证明是可行的，并据此结合已成熟的区域生态功能区区划理论，以吴忠的自然、社会条件和其它有关区划结果等为依据，对吴忠整体进行了生态功能区区划，然后根据国家、宁夏与吴忠三级政府出台的各级别生态建设战略目标、任务，按照有关生态恢复学等有关理论，详细地对七大生态功能区中各受损生态系统的恢复与重建模式进行研究，提出了不同的生物与工程模式及实施办法、途径、措施。
