This study utilizes ArcGIS, the InVEST model, and SCS model to analyze remote sensing data from central urban areas of Chengdu. The analysis simulates water yield runoff within area while calculating conservation capacity for each land use type using balance method. aims address challenges faced by Chengdu in implementing its sponge city initiatives. results reveal that spatial distribution direct generally follows a pattern “low periphery high center”. Transportation, commercial, industrial, residential types account 74.7% total surface area, emphasizing their importance rainwater management development. Water varies across different types, with bodies exhibiting lowest artificial highest capacity. initially exhibited downward trend before increasing, type, climatic factors, vegetation coverage identified as primary drivers yield. gradually decreased, higher values observed east south lower north west. These trends differences can be attributed expansion alterations cover. Based on these findings, this assessed risk waterlogging provided recommendations optimizing low-impact development (LID) strategies. provides scientific foundation initiatives, mitigation, strategies
