潍坊城市地质环境质量综合评价

Comprehensive Evaluation of Geological Environment Quality in Weifang City

摘要:

该文在充分收集以往资料的基础上，结合潍坊城市地质调查项目获得的原始数据，进行了工程建设适宜性、区域地壳稳定性、地下水质量、地下水富水性等单地质环境要素评价，采用层次分析法和综合指数法，对潍坊市城市地质环境质量进行了综合评价研究。潍坊市城市地质环境质量分为好区、较好区、较差区和差区等4个等级，好区面积350.39km2，主要分布于城区北部一带；较好区面积562.68km2，主要分布于质量好区外围；较差区面积1004.70km2，主要分布于央子街办外围及峡山水库一带；差区面积687.23km2，主要分布于北部沿海区域及萧家营、老坊子区一带。

Abstract:

Based on the collection of previous data, combining with original data gained in geological survey projects in Weifang city, the suitability of engineering construction, regional crustal stability, groundwater quality, groundwater enrichment and single evaluation of geological environment factors have been carried out. By using AHP and comprehensive index method, geological environment quality in Weifang city has been comprehensively evaluated. Geological environment quality in Weifang city can be divided into good area, relative good area, poor area and relative poor area. The square of good area is 350.39km2, and mainly distribute in the north of the city. The square of relative good area is 562.68km2, and mainly distribute in the peripheral area of good quality. The square of poor area is 1004.70km2, and mainly distribute in the surrounding area of Yangzijie street office and Xiashan reservoir area. The square of relative poor area is 687.23km2, and mainly distribute in the northern coastal area, Xiaojiaying and Fangzi area.
