民勤县生态经济功能区划

摘要

Based on analysis of structure and functions of the eco-economic system of Minqin County,which is located in the lower reaches of the Shiyang River Basin,an indicator system was established for regionalizing of the eco-economic system of the county by function,using the system clustering method.The county was divided into five zones,the northeast irrigated agricultural zone of sandy saline soils,the central town comprehensive development zone,the northwest desert ecological protection zone,southeast ecological agricultural zone,and central riparian agro-forest-animal-husbandry development zone.The characteristics of the structure and functions of the eco-economic systems of the zones,approaches to improvement of the eco-economic systems and orientation of the development of the zones are discussed.%在分析石羊河流域下游民勤县生态经济系统结构与功能的基础上,建立生态经济功能区划指标体系,利用系统聚类方法对民勤县生态经济系统进行功能区划,将民勤县分为东北部沙盐地灌溉农业区、中心城镇综合发展区、西北部荒漠地生态保护区、东南部生态农业区和中部沿河农林牧业发展区5个功能区,并分析了民勤县各区域生态经济系统的结构与功能特点、改善途径及区域发展方向.
