摘　　要：利用经济手段进行生态环境综合治理是目前国内外已获共识的一种有效的和根本的途径。利用灰色关联法对大兴县的产业结构进行了分析 ,并利用区位商和PCA分析的方法对主导产业进行综合分析 ,探讨了在行政县域内亚湿润沿河沙地生态环境问题解决的模式和途径 ,以保证该区域内人口、经济、资源与环境的协调发展和持续发展。Since the solution of environmental problems by economic methods has been recognized as an efficient way by all scientists at home and abroad, the domain structure in Daxing county is analyzed in this paper with the Grey System Model and its dominant domain is discussed by means of Area Quotient and principal component analysis. Based on such an analysis, this paper discusses the economic mode for the environmental problems on the river-sand land in the sub-humid region of the county, so as to realize a coordinated and sustainable development of population, economy, resources and environment within the region.
