Land ecological security is related to the development of human society. In order to clarify the overall pattern of ecological space in the study area, check the list of overall resources in the study area, and understand the current situation of land natural ecosystem, the identification and pattern optimization of ecological space is an effective way to ensure the ecological security of land in the region. Based on the comprehensive ecosystem service importance evaluation model and ecosystem sensitivity evaluation model, ArcGIS 10.5 platform, selecting evaluation indicators according to the ecological background of the study area, Henan Province was taken as the study area, fuzzy gamma model was used to identify the ecological space based on the fuzzy logic theory, and the scheme of ecological space optimization pattern was put forward. The results show that there are four types of ecological spaces in the study area: ecological protection space, restriction space, control buffer space and optimization development space; the area of ecological protection space is 13 668.73 km2, accounting for 8.3% of the total study area, the area of restriction space is 19 161.78 km2, accounting for 11.63% of the total study area, the area of control buffer space is 9 434.67 km2, accounting for 5.72% of the total study area;, the area of optimized development space is 122 480.73 km2, accounting for 74.34% of the total study area. According to the results of ecological space identification, the optimization scheme of ecological space pattern in the study area is proposed. The study area is divided into three areas, two belts and three blocks, which are Taihang Mountain ecological red line protection area, Dabie Mountain ecological red line protection area, Funiu Mountain ecological red line protection area, Yellow River ecological protection belt, Huaihe River ecological protection belt, east Henan plain ecological protection block, west Henan hills ecological protection block and north Henan hills ecological protection block.
