基于层次分析法的海岸带地质环境质量指标体系研究——以烟台市海岸带为例

Study on Geological Environmental Quality Indicator System in Coastal Zone Based on Analytic Hierarchy Process——Taking the Coastal Zone in Yantai City for Example

以烟台市海岸带出现的地质环境问题和发生的地质灾害作为评价对象,应用层次分析法构建了影响海岸带地质环境质量的指标体系,分析了影响各子系统的主要因子;通过构造AHP模型及比较判断矩阵,并进行一致性检验后,得出地下水超采漏斗分区、矿山开采、海咸水入侵等因素是影响海岸带地质环境的主要因素,从而为烟台市海岸带地质环境的治理提供了依据。

This paper studied the geological environment problem and geological hazard along the coastal zone in Yantai City. The Analytic Hierarchy Process was used to evaluate the factors affecting the geolog- ical environmental quality in the coastal zone and analyze the main factors affecting the subsystems. By constructing an AHP model and comparative judgments of matrix and in combination with mathematical calculation and one-time examination, the paper obtained that the over-exploitation of groundwater,mining and sea water intrusion are the main factors affecting the geoenvironment. The present study is important in improving the geological environmental quality in the coastal zone.
