Ecological network construction and optimization is an effective way to balance the contradiction between regional development ecological protection in process of urbanization. The urban–rural fringe both a frontier zone direction urban expansion important space for improving environment. However, there are few studies on how construct optimize networks fringe. In this paper, morphological spatial pattern analysis (MSPA) minimum cumulative resistance model (MCR) were firstly employed initially reveal characteristics problems security study area. Then, new strategy with multi-scenario coupling gradient zoning was proposed meet maximization integrated benefits future protection. results show that: (1) Urbanization caused high fragmentation patches, exerted strong hindrance processes.

Cities experience the most intensive level of human activity. As a result, more than 60 % global CO2 emissions come from urban areas. Urban green space has dual ecological benefits increasing carbon sinks and reducing emissions. Creating is essential to promoting development low-carbon cycle in city. Therefore, exploring quantitative structure spatial pattern optimization perspective balance can effectively improve total sink Based on theory, this paper first evaluates offsetting capability (COC) Beijing 2020.
