北京门头沟新城规划分区地质环境适宜性探讨

近年来,人类工程活动引发的地质环境问题日益严重,因此在城市建设规划阶段,进行地质环境适宜性的分析与评价十分必要。本文在门头沟规划新城前期区域工程地质勘查工作基础上,通过对区域工程地质条件、水文地质条件、地质灾害危险性、工程建设场地适宜性以及规划建设对地质环境的影响程度等主要因素进行综合分析与研究,对门头沟新城规划分区的地质环境适宜性进行了评价与探讨。认为该新城规划分区的地质环境总体来说是适宜或基本适宜的,但个别功能分区的地质环境不适宜。对于基本适宜及不适宜的功能分区,指出了其存在的主要地质环境问题,并提出了有针对性的建议。

Discussion on fitting of geology environment in planning area for the New Mentougou County in Beijing

In recent years,the geology environment question caused by the human engineering activity becomes more serious day by day.Consequently,it is very necessary to analyze and evaluate the fitting of geology environment at the planning stage of the city construction.On the basis of the prior regional engineering geological survey on the new city of the Mentougou County,the paper evaluates and discuses the geology environment fitting of the planning area of the new Mentougou County by comprehensive analyzing and studying the engineering geology condition,hydrology geology condition,geologic hazard risk,the fitting of the engineering construction yard and the influence on the geological environment from the engineering construction.The paper thinks that the geological environments of the new Mentougou city is feat or basically feat on the whole,but the geological environments of the individual function regions is unsuited.For the basically feat or unsuited regions,the paper pointed out main geologyical environment question and the pertinent suggestions.
