[Objective] The problems of frequent flood and waterlogging disasters, poor drainage and inadequate utilization of rainwater resources in small and medium-sized riverside towns in Piedmont alluvial-alluvial plain were studied in order to provide reference for rational planning and application of rainwater storage facilities in small and medium-sized towns.[Methods] By choosing Yingqiu Town of Weifang City, Shandong Province as the research object, and according to the current drainage and land use situation of the study area, the planning steps of "sub-catchment division, land use mapping, water storage calculation, establishment of technical system and determination of construction sequence" were put forward based on GIS.[Results] The comprehensive rainwater storage and utilization system of "pervious pavement + concave green land + grass waterway, simple biological retention pond + wet pond, rainwater wetland" were adopted and its layout was planned. By introducing the hydrological sensitivity index, the order of sponge city construction in the catchment area of the township was specified.[Conclusion] This paper combines the technology of rain and flood utilization with the landscape planning of the town. The actual storage capacity of the comprehensive facilities with low impact is larger than the designed storage capacity of rainwater, which realizes the storage and utilization of rainwater resources in the town.
