基于高效生态农业布局导向性的资源环境承载力评价—以黄河三角洲高效生态经济区为例

Resource and Environment Carrying Capacity Assessment of Efficient Ecological Agriculture Oriented Layout—Settingcase Efficient Ecological Economic Zone in Yellow River Delta as an Example

摘要:

该文在对研究区资源环境本底基本了解的基础上，建立了包括耕地资源、水资源、社会经济资源、土壤环境、极端气候发生率和地质环境6个二级指标的资源环境承载力评价指标体系，采用定性和定量相结合的方法，利用层次分析法确定相关指标权重，分别对6个要素进行承载力评价。在各单元要素评价基础上，结合黄河三角洲高效生态经济区农业发展要求，划分出了沿海湿地生态系统保护带、北部盐渍化土质特色种植区、南部优质粮食生产区和果蔬集中种植区4个生态农业布局适宜区，并提出发展建议。

Abstract:

In this paper, on the basis of studying resource and environment in the study area, resources and environment carrying capacity evaluation system which including six secondary indicators as land resources, water resources, social and economic resources, soil environment, the incidence of extreme weather and geological environment have been established. By using a combination of qualitative and quantitative methods, by using AHP, relevant index weight has been determined, and carrying capacity of six elements has been evaluated respectively. On the basis of evaluating single element, combining with development requirements of agriculture in efficient ecological economic zone in the Yellow River Delta, four ecological agriculture layout suitable areas have been divided, they are coastal wetland ecosystem protection zone, salinization of soil characteristics in northern growing areas, the southern highquality grain production areas and concentrated fruit and vegetable growing areas, and relative development recommendations have been put forward.
