【摘要】 本文在北京顺义区国土资源与地质环境大调查工作的基础上 ,对顺义区的主要地质环境进行了初步调查 ,认为该区地质环境比较脆弱 ,如断裂活动性强、地震活动频度高、地壳稳定性差、第四纪地层发育、松散易液化的细粉砂土及不规则分布的软土分布面积较广 ,地面及地基工程地质条件较差、水资源不足 ,容易发生地震、地裂缝、砂土液化、地面沉降、水环境污染及地基失稳等地质灾害 ,建议进行专门的综合性地质环境调查研究工作 ,为顺义区总体发展规划、保护地质环境以及减少地质灾害损失等提供科学依据。更多还原

【Abstract】 On the base of the large survey of Shunyi county land resources and geologic environment, this paper preliminarily study the present situation of geologic environment and geologic hazard, regard the geologic environment of the Shunyi county is unfavorable, e g strong crust activity and faulting,frequent earthquake, inferior crust stability, developed Quaternary strata,broad loose sandy soil,and bad geologic condition of ground and foundation engineering, insufficient water resources, it can easily cause geologic hazard such as ground deformation, earthquake, ground fissure, land subsidence,water environment pollution and unstable foundation, suggest to make on the special comprehensive investigation of geologic environment and geologic hazard,to provide scientific basis for the general plan of development, for the protection of ecological environment and for the reduction of loss caused by the geologic hazards更多还原
