摘　　要：汇集西北6省区近300个气象站点的多年气象数据,400多个县市的土地利用和社会经济统计数据,提取降水、气温、湿度、土地利用类型、人口、GDP、矿产资源、产业结构(三次产业)等要素,设计了水热状况、人类活动强度、工业化程度、城镇化程度等指标,借助GIS工具,通过要素指标的空间分异特征研究,构筑指标体系,进行了以县域尺度为最小空间单元的生态经济区划研究。根据西北地区县域尺度上的生态环境状况和人类活动状况,将西北划分为3级27个生态经济区。As a language in describing the earth＇s surface, regionalization has been developed to the stage of “integration” over systems of nature and humanity and “pertinence” for special purpose from the straightforward representation of natural zones. Eco-economic regionalization is a new field probing into the integration of nature and human systems. Based on the theories and methods in nature and ecological regionalizations, this study aimed to develop new methods and index designs for eco-economic regionalization, taking Northwest China as an example. The key indices, including water-heat condition, human activity pressure, industrialization level, and urbanization progress, were designed to reflect the pertinent driving factors such as precipitation, temperature, humidity, LUCC, population, GDP, mineral resources, and industrial structure. GIS method was applied to analyze the spatial disparities of the above factors and indices in building the index system for eco-eeonomic regionalization. Sevearl years of climatic data from about 300 stations, and socio-economic and LUCC data for about 400 counties in six provinces in Northwest China were used in the analysis and development of the index system. In the end, the paper presented a method for eco-economic regionalization in Northwest China by dividing the area into three levels： domain, region, and district, with county as the basic units. According to the eco-environment and human activities, Northwest China was partitioned into four eco-economic domains based on the general physiognomic features, physical zones, agricultural production, and integrated human activities represented by an index of “pressure of integrated human activities”. There were 13 eco-economic regions in level 2, determined by factors including physical sub-zones, land use, energy and mineral resources. The factors of urbanization, industrialization, cultivated land area, and food production were used to define the economic districts, the lowest level in the proposed eco-economic
