| 摘 要： | 采用层次分析法对科尔沁沙地西北缘地质环境、生态环境、社会环境进行分析, 构建一套以适应农牧业发展为目标层的评价指标体系, 并计算区域生态地质环境质量的综合指数, 对生态地质环境状况进行评价. 通过对评价结果统计认为: 生态环境较比地质环境、社会环境对整个评价结果的影响更大, 其中土地质量是最主要因素; 研究区所有的评价单元中有86%处于中等及偏下的水平. 该研究结果对正确认识研究区生态地质环境具有重要的意义.

| Abstract: | In this study, the geological, ecological and social environment of the northwest margin of Horqin sandy land are analyzed by analytic hierarchy process (AHP). An evaluation index system is established to adapt to the development of agriculture and animal husbandry as target layer, and the comprehensive indexes of regional eco-geological environment quality are calculated to evaluate the eco-geological environment. According to the results, it is considered that the eco-environment impacts on the whole evaluation results more than the geological and social environment does, with land quality as the key factor. Of all the evaluation units in the study area, 86% are at a medium or lower level. The results are of great significance to correctly understand the eco-geological environment of the area. |
