毕节七星关区生态功能区划

摘要

利用 GIS 软件采集七星关区地形高程、土壤类型、气温、降水、生态系统类型等生态要素的空间数据，对生态环境敏感性和生态服务功能重要性进行评价；明确区域生态敏感性和生态服务重要性特征及其空间分异格局。在此基础上，拟定县域生态功能区划的单位等级系统，遵循生态功能区划的相关原则，运用定量和定性相结合的分析方法，对毕节七星关行政辖区范围进行生态服务功能分区。结果分为2个生态功能区、4个生态功能亚区和17个生态功能小区，为七星关区生态保护和社会经济持续发展提供理论依据。%　　Take advantage of the software of GIS to collection the spatial data of Ecological elements, which are in Qi Xing -guan County, such as Terrain elevation, soil type, temperature, the precipitation, eco-system type, which is to evaluate the eco-envi-ronmental sensitivity and the importance of ecosystem services. The study should explicit the regional of ecological sensitivity, and the importance of the ecological services' characteristics, and the Heterogeneity Patterns of Spatial.On the basis, to study out the unit level for the County ecological function regionalization. The study should following the relevant principles of ecological function regionalization and using the methods of a combination of qualitative and quantitative to analyze. The study should partition the ecological function regionalization, which belongs to the range of Qi Xing -guan County in Bijie, and should divide the county into 2 ecological function regionalization and 4 ecological function of the sub-region and 17 ecological function of small regionaliza-tion. The study should provide a theoretical basis for Qi Xing -guan County, which is to ecological protection and the develop-ment of the sustainable social and economic.
