However, with the global environmental change and the disturbance of human activities ( Song et al., 2015), EL is facing more serious problems of loss and degradation than ever before ( Puskás et al., 2021). As a “barometer” ( Yu et al., 2015) for measuring ecological quality, EL plays an important role in balancing regional and global ecosystems ( Colding, 2007 Feng et al., 2021a), ensuring national land ecological security, coping with global climate change, and improving the quality of human life ( Guan et al., 2018). The degrees of fragmentation were mainly at low and high levels and 3) the REL in Longxi County has different evolution laws in different gradients.Įcological land (EL) has ecological functions such as water conservation, soil protection, climate regulation, environmental purification, and biodiversity protection. Its diversity, dominance, and shape index were mainly at low and medium levels. The results show 1) the rural ecological background conditions of Longxi County are good, and the area of ecological land (EL) accounts for 90.45% of the total area of the county 2) there are significant differences between the spatial feature index and spatial pattern of REL in Longxi County. Therefore, we can clarify the impact of natural and human factors on EL under different gradients. Taking Longxi County as an example, this research studied the spatial pattern of REL based on the landscape pattern index and analyzed the multi-dimensional gradient spatial differentiation characteristics of REL. This has far-reaching significance for the improvement of village appearance and the delineation of an ecological safety network. Studying the gradient differentiation of rural ecological land (REL) from a microscopic perspective is conducive to the pattern optimization, scientific control, and protection of REL. 3Institute of Urban and Rural Development and Collaborative Governance of Northwest, Lanzhou, China.2Key Laboratory of Resource Environment and Sustainable Development of Oasis, Lanzhou, China.1College of Geography and Environmental Science, Northwest Normal University, Lanzhou, China.Libang Ma 1,2,3* Yao Yao 1 Tianmin Tao 1 Yanling Zong 1
