Abstract: Huangpi District is Wuhan City’s largest town rich in mountain and water resources, and constructing its ecological security pattern is an important guarantee for the sustainable development of Wuhan City. Taking the land utilization alteration data and DEM elevation map of Huangpi District photographed in December 2017 as the main data source, and taking forest land, water area and wetland with high ecological sensitivity as source areas, the author establishes the minimum cumulative resistance model to identify ecological corridors and nodes, divide ecological function areas, construct and optimize the ecological security pattern of Huangpi District. The research results show that: (1) The identified ecological source areas in the area studied is 169.55 km2, accounting for 7.5% of the total area of the district, and showing the spatial distribution characteristics that“they are distributed at both ends, which are relatively independent, with poor connectivity”; (2) Extracting a total of 132 ecological corridors and 83 ecological nodes. From the perspective of spatial distribution, corridors are concentrated in mountains in the northern and waters in the south. It is the most difficult to connect the land between urban construction land and large-scale cultivation land. (3) According to the calculation results, the area studied is divided into ecological security-level areas with five different levels, and from south to the middle part and from north to the middle part, the ecological security level roughly shows a trend from low to high. Optimizing the ecological network connection plays an important protection role in safeguarding the ecological security of the region, maintaining the ecological stability of the region and alleviating the ecological pressure of the region.
