内蒙古伊金霍洛旗生态保护红线研究

Delimitation of ecological protection red line in Ejin Horo Banner of Inner Mongolian

以伊金霍洛旗为样本,初探生态红线划定落图落地技术,为保护生态环境,合理利用和优化配置土地资源提供参考。主要利用最小累积阻力模型、马尔萨斯预测模型、综合分析方法进行三生用地预测及生态红线保护区划定。结果表明:1)保障区域人口粮食安全的耕地需求量、经济社会发展的生活功能用地量、具有保护生态环境功能的土地面积分别占研究区总面积的7.4%、3.05%和89.55%。2)划定的生态保护红线区占研究区总面积的16.45%,主要分布在伊金霍洛旗东北部和西北部地区,主要的土地利用类型为草地和林地。3)伊金霍洛旗是生态敏感性等级较高的区域,对其划定生态红线保护区既有现实意义,也可以在未来的社会经济发展过程中提高人们保护生态环境的意识。

The purposes of this research are to preliminarily probe the technology of delimiting the ecological red line so as to provide a reference for protecting ecological environment and rational utilization of land resources. Method of the minimum cumulative resistance （MCR） model, Malthusian prediction models and comprehensive analysis were employed to predict PLE land area and delimit nature reserve of ecological red line. The results in- dicate that ： 1 ） Cultivated land that is demanded for food security in region, living land area that is demanded by economic and social development, and the land area that has ecological function account for 7.4% ,3.05% and 89.55% of the research region, respectively. 2） nature reserves that have been delimited with ecological red line account for 16.45% of research region; they mainly distribute in northeastern and northwestern Ejin Horo Banner. The grassland and forestland are the main land use types. 3 ）It is concluded that Ejin Horo Banner is an area where the ecological sensitivity is higher. Therefore, delimiting ecological red line is practically needed and can enhance people＇s consciousness of protecting ecological environment in future with the development of society and economic.
