基于层次分析法的云门山地区生态适宜度评价

Evaluation of Ecological Suitability in Yunmen Mountain based on the Analytic Hierarchy Process

区别于传统的山地生态适应性评价,该文采用层次分析法确定以地形、景观、生态、政策四个方面作为影响因子的指标体系,应用GIS技术建立评价模型,对云门山地区进行了生态适宜度评价。为了避免开发带来的山地生态环境退化,依据评价结果,提出了因地制宜、退耕还林、增加水体比重等生态开发措施。

Different from the traditional evaluation of ecological adaptability of mountain, Analytic Hierarchy Process （AHP） is used in this paper to determine the index system of four impact factors in terms of topography, landscape, ecology and policy. Meanwhile, the technology of GIS is applied to establish the evaluation model which is adopted to evaluate the region of Yunmen Mountain in ecological suitability. In order to avoid the deregulation of ecological environment of mountain generated by the development, some ecological measurements including the local conditions, forest promotion and increase the proportion of water system are finally provided on the basis of evaluation results.
