摘　　要：以成都某红层丘陵区为研究对象,综合考虑海绵城市建设的“渗、蓄、净”几方面影响,认为红层丘陵区海绵城市建设主要的地质影响因素包括坡度、岩土渗透性、下垫面条件、第四系覆盖层厚度、地下水位埋深、水系分布、植被覆盖程度、水污染程度等,并通过现场调查及实施相应的渗透试验等方式,最终确定坡度、第四系覆盖层厚度、岩土渗透性对海绵城市建设的影响更大。随后确定各因子权重值,构建评价体系,确定研究区海绵城市建设的地质适宜分区,为后期其他红层丘陵地区的海绵城市建设相关规划提供理论基础。This paper takes a red layer hilly area in Chengdu as the research object,and considers the influence of"infiltration,storage and purification"of sponge city construction,and considers that the main geological influencing factors of sponge city construction in red layer hilly area include slope,geotechnical permeability,sub-bedding surface condition,thickness of quaternary cover layer,depth of buried water table,distribution of water system,vegetation The influence of slope,quaternary cover thickness and geotechnical permeability on sponge city construction was finally determined through on-site investigation and implementation of corresponding permeability tests.Subsequently,the weight values of each factor were determined,the evaluation system was constructed,and the geological suitability zoning for sponge city construction in the study area was determined to provide the theoretical basis for the later planning related to sponge city construction in other red layer hilly areas.
