[Identification and Strategy of Key Areas of Land and Space Ecological Restoration Based on the Ecological Safety Pattern: Taking Henan Province as an Example].

Building an ecological safety pattern is conducive to coordinating the contradictions between the two types of ecological processes of protection and development and promoting the ecological protection and restoration of land and space. Taking Henan Province as the research area， based on the results of morphological spatial pattern analysis （MSPA）， the landscape connectivity of the core area plaque was evaluated to extract the ecological source， construct the ecological resistance surface through the comprehensive index method， and modify it with the help of night light data. Circuit theory was used to extract Henan's ecological corridors， ecological pinch sites， and ecological obstacle sites； identify the key restoration areas in Henan Province； and formulate corresponding restoration strategies. The results showed that： ① There were a total of 64 important ecological sources in Henan Province， with a total of 22 615.77 km2， mainly distributed in the western region and the northern and southern provincial boundaries. ② There were a total of 120 major ecological corridors in Henan Province， with an average length of 13.29 km. The ecological obstacle areas in Henan Province were mainly distributed in Zhengzhou City， Pingdingshan City， and Nanyang City. ③ The ecological safety pattern of "three areas in one belt-four corridors-two groups-multi sites" has been established， and optimization suggestions have been put forward for different regions， which can provide references for the policy formulation of relevant government departments and promote sustainable development in the region.
