嘉兴城市地下空间资源开发利用影响因素探讨

Discussion on Affecting Factors of Urban Underground Space Development and Utilization in Jiaxing,Zhejiang Province

地下空间资源的开发利用与地区资源条件、环境条件、经济社会条件、工程建设需求以及开发利用现状等密切相关,分析地下空间资源利用与城市环境、地质环境、经济社会环境之间的相互作用关系,是判定地下空间资源利用影响因素、科学建立地下空间资源适宜性评价指标体系的前提基础。嘉兴市为第四纪多旋回堆积平原地区,第四系松散土体广泛分布、厚度巨大,具有优厚的地下空间资源基础,但地质环境条件对地下空间资源开发利用的制约影响也最为主要,结合地区实际,本文主要将影响城市地下空间资源开发利用的因素按地质环境条件、经济社会条件和现状利用条件三大类进行全面分析,探讨影响嘉兴城市地下空间资源开发利用的主要因素。

Development and utilization of urban underground space is closely related to local resource,environment,economic society condition,engineering construction demand,development and utilization status and so on.Analyzing the relations between them are the basis for determining the affecting factors of urban underground space utilization and establishing suitability evaluation index system of underground space resource.Jiaxing is located at Quaternary polycyclic accumulation plain.The Quaternary loose earth is widely distributed and its thickness is huge.There is munificent underground space resource in Jiaxing.But geological environment condition restricts the development and utilization of underground space resource.Combining regional reality,this paper comprehensively the affecting factors that influenced the development and utilization of underground space resource.Those factors divided into three categories,which geological environment,economic society condition and utilization status.The major factor that affects the development and utilization of underground space resource in Jiaxing discussed.
