Study on Spatial-temporal Heterogeneity of the Taihang Mountain Nature Reserve

In order to explore the spatial pattern and spatial heterogeneity of the Taihang Mountains nature reserve, Moran's I, multidistance spatial clustering, kernel density analysis, and geographical detector were employed. The results showed that the emphasis of nature reserve construction would be different in different time periods. The construction history of the Taihang Mountain nature reserve was four stages, reflecting the establishment process of spatial structure of nature reserve cluster. The distribution of nature reserves was aggregated as a whole, wetland parks and scenic spots were more concentrated than other nature reserves. In terms of space, the area of nature reserves formed a dense core area centered on Yixian,Laishui and Wutai,Lingshou. And the core zone formed by connecting Xingtai,Huguan and Jiyuan in series. There was significant spatial heterogeneity in the Taihang Mountain nature reserve. In the planning of nature reserve area construction across Taihang Mountains, it is necessary to adopt measures suited to local conditions to promote balanced development and establish a protected area system that aligns with the characteristics of the Taihang Mountains.
