基于景观分类的宁夏限制开发生态区主体功能细分研究——以盐池县为例

A Segmentation Research for the Major Function in Ningxia Limited Development Ecological Region Based on the Landscape Classification——Take Yanchi as Case Study in Ningxia

宁夏主体功能区域划分的限制开发生态区是我国少数民族回族的聚居区和生态脆弱区,区域发展和生态保护的矛盾十分突出。对限制开发区进行主体功能区细分,以便对不同类型限制开发区生态和农业、牧业价值进行综合评估,对限制开发区的生态保护、区域发展有重要的理论意义和应用价值。从地表景观分布角度出发,运用ENVI软件对盐池县遥感影像进行景观分类,选取相关景观指数从区域景观自身脆弱度角度和区域人类活动适宜性角度考虑,结合盐池县乡镇界限,划分出以乡镇为单元的4类主体功能区:弱限制开发区、中限制开发区、强限制开发区和禁止开发区,为乡镇经济发展提供宏观指导和依据。

Limited development zone of Ningxia is Hui Community and the zone of ecological fragile and the agricultural region. The contradiction between regional development and ecological protection is very promi- nent. Limited zone of the district subdivision has a comprehensive assessment for ecological and agricultural, animal husbandry value in different types of limited development zone and has important theoretical signifi-cance and application value in ecological protection, regional development. From the perspective of landscapedistribution, this article used of the ENVI software to classify Landscape based on remote sensing image of Yanchi. Based on considering the regional landscape vulnerability degree, regional human activity suitabilityis selected from landscape index. Combining Yanchi County Township boundaries, divide the 4 major regions by township unit, which are weak limited development zone, limited development zone, strong restriction de- velopment zone and prohibited zone. The conclusion can provide the macro guidance and basis for the devel- opment of township economy.
