基于GIS空间分析的地质环境承载能力评价——以泰安市高新区为例

Evaluation on Geological Environment Carrying Capacity Based on GIS Spatial Analysis—— Setting High-tech Zone in Tai’an City as an Example

摘要:

近年来由于人类活动强度超出当地的地质环境承载能力，破坏了人与自然的平衡，带来了一系列地质灾害、地下水污染等环境问题。为科学合理地分析泰安市高新区地质环境的承载能力，本文在分析研究区内地质灾害、构造稳定性、水土环境等地质环境特征基础上，构建了地质环境承载能力评价的5项本底因子和4项状态评价指标，采用 GIS 空间分析技术将各评价指标进行空间叠加，建立了评价矩阵，对高新区地质环境承载承载能力进行了评价研究。结果表明研究区地质环境承载能力整体状况较好，承载能力中等以上区占比86.15%，承载能力较弱区占比10.2%，承载能力弱占比3.52%。本研究成果为资源环境承载能力监测预警提供靶区，同时也为国土空间规划的编制提供依据。

Abstract:

In recent years, due to the intensity of human activities exceeding the bearing capacity of local geological environment, the balance between man and nature has been destroyed, and a series of environmental problems have been caused, such as geological disasters and groundwater pollution. In order to scientifically and reasonably analyze the bearing capacity of geological environment in high-tech zone of Tai'an city, based on the analysis of geological environment characteristics, such as geological disasters, structural stability, water and soil environment, five background factors and four state evaluation indexes of geological environment bearing capacity are constructed. By using GIS spatial analysis technology, the evaluation indexes in space have been superimposed, the evaluation matrix has been established, and the bearing capacity of geological environment in high-tech zone has been evaluated. It is showed that the overall carrying capacity of geological environment in the study area is good, the area with medium or above bearing capacity is about with 86.15%, rather weak bearing capacity is 10.2%, and weak bearing capacity is 3.52%. This study will not only provide target areas for monitoring and early warning of resources and environment carrying capacity, but also provide the basis for the compilation of land spatial planning.
