Rapid urbanization brings a series of sustainable development challenges such as ecological damage and environmental pollution, which needs to be avoided in the stage of urban planning. The ecological infrastructure construction reflects the concept of ecosystem restoration and collaborative environmental governance. It is an effective means to guide urban planning under the new urbanization background. Nowadays, macro-scale ecological infrastructure construction is relatively systematic at home and abroad, while the micro-scale is relatively lacking. Due to the small scale and lacking network, the ecological infrastructure construction in community and other small scale regions in China can not prevent the problems of rainwater waterlogging and non-point source pollution emerge. In this study, the Promoter Regions in Xiong'an New Area as the research object, a design method, and the technical process of urban micro-scale ecological infrastructure are established. (1) Based on the site's survey and theoretical research, analyze the site current condition, and consider the relevant factors such as natural factors, physical perception, psychological perception, and the ecological process to construct the ecological infrastructure system where "corridor as the bone, patches as the node". (2) Identify the regional functional ecological patches, which includes major animal activities, migration, and conservation of plant diversity, to construct a systemic corridor connecting the whole city to provide multiple functions, a structural corridor to increase ecosystem services within the city, and a local functional corridor to infiltrate ecosystem services into the urban fabric. (3) Evaluate the expected effect of ecological infrastructure construction by residents' perceptions and annual runoff control rate. The ecological infrastructure construction helps alleviate the ecological environment problems faced by the construction of Xiong'an New Area, guarantee the living environment's quality, and provide a reference for future urban construction.
