[Construction of ecological security pattern in the agro-pastoral ecotone based on surface humid index: A case study of Hangjin Banner, Inner Mongolia Autonomous Region, China.].

The construction of regional ecological security pattern can effectively protect regional ecological security and achieve regional sustainable development, which has become one of the key topics in landscape ecology. The construction of regional ecological security pattern is particularly important for the Inner Mongolia Plateau, which is characterized by relatively fragile ecological environment and single land cover type. Considering regional natural environment characteristics, five typical ecosystem services, such as food supply, carbon fixation and oxygen release, soil conservation, water yield and habitat conservation, were selected to assess the importance of natural habitats with Hangjin Banner of Inner Mongolia Autonomous Region as a case study area.
