Abstract: Abstract: 【Objective】The objective of the present study is to construct hilly mountain land stormwater management mode based on the resilience theory, to calculate the bearing ability of flood and put forward the corresponding mode of stormwater management.【Method】Based on the evolution resilience theory and bionics principles, vector terrain data was used to analyze the topography, slope, slope direction, flow direction and confluence with the help of GIS spatial analysis. Then, the natural flooding area was drawn. Furthermore, the stormwater pattern was obtained. 【Results】The floodable land in the researching area was about 32.57 hm2 with the surface flooding ratio of 55.38%. Despite the strong flood-ability and seepage-ability, the rainfall flood transferring ability was weak for the floodable land was mostly scattered with weak continuity. On this basis, a robust stormwater management mechanism mode of “palmately compound leaves” structure with hilly mountain features was constructed. The stormwater management pattern in natural flooding area with runoff networks of tertiary “venation” structure, catchment centers of tertiary “base” structure and natural floodplains of tertiary “mesophy” structure was developed which is suitable for the area of hilly mountain. The management pattern for the “palmately compound leaf” structure of the tertiary runoff network, the tertiary water transfer center and the tertiary natural flood protection zone was put forward. 【Conclusion】Based on the resilience theory, the hilly mountain “palmate compound structure” stormwater management mode was conducive to the effective penetrating, transferring, stormwater controlling and the protection of the ecosystem in the hilly mountain area. The results could provide references for the stormwater management mode construction in areas with similar features.
