摘要:
开展地质环境区划研究,对有效保护地质环境、履行地质环境保护管理职能具有重要意义。本项目既是国土资源部规划司开展全国地质环境区划的试点,又是江苏省地质环境保护规划的支撑性工作,是在国内尚无成功的范例,又没有成熟的理论研究体系下开展的。项目在分析地质环境区划概念与内涵的基础上,明确了江苏省地质环境区划“六专(专题区划)一综(综合区划)”的区划思路;从地质环境的自然属性和社会属性两个层面考虑,采用层次分析法,建立了地质灾害(防治)、矿山地质环境(保护)、山体资源保护、地质遗迹保护、地下水污染防治和土壤污染防治等6个专题区划评价指标体系;以MapGIS的空间分析模块为评价平台,进行了6个专题区划评价;基于6个专题区划成果,建立地质环境综合区划评判体系,以地质环境问题为导向进行一级区划,以地质环境功能为导向进行二级区划;从地质资源保障及地质环境安全角度,提出了地质环境保护规划建议。

Abstract:
Research on division of geoenvironment is of great significance to protect the geoenvironment effectively and to perform the functions of the geo-environment protection and management.This proposal is not only the pilot project for nationwide geo-environment classification carried out by Planning Division of Ministry of Land and Resources, but also an essential part of the sustainable geo-environment protection for Jiangsu Province. It was conducted as first maturely demonstration project, and therefore the implementation of this proposal will provide the fundamental principles for any further researches.Basing on the analysis of concept and connotation of geoenvironment regionalization, we established the ideas of geoenvironment regionalization in Jiangsu which included a comprehensive division and 6 specialized divisions. Considering the natural and social attributes of the geo-environment, we established the evaluation index system for 6 specialized divisions, i.e., geological disasters (prevention), mine geological environment (protection), mountain resource conservation, geological heritage protection, groundwater pollution prevention, and soil pollution prevention. The evaluation of 6 specialized divisions was carried out by the space analysis module of MapGIS.The geoenvironment comprehensive division had been done based on the results of specialized divisions. The first order of comprehensive geological environment division is oriented to the geological environment problems, and the second order of division is oriented to the geological environment function. This paper offered geoenvironmental protection plan proposals from two aspects of geological resources security and geological environmental safety.
