Abstract
To protect the ecological environment of peak forest landform and maintain its integrity and stability, the optimization method of spatial structure characteristics of peak forest landform in Wulingyuan Scenic Area was studied. By using GIS and digital topographic analysis to study the basic features of sandstone peak forest landform, Wulingyuan peak forest landform and karst peak forest have great differences in lithological composition, weathering resistance is better than Cheltenham Badland landform; by using tree theory to analyze the features of Wulingyuan peak forest landform, according to area weight serialization of contour tree nodes, we can know the depression area. The karstification is stronger than that of the peak forest area, and the surface is relatively fragmented. Based on different landscape indices, the landscape pattern of Wulingyuan peak forest is analyzed. The fragmentation degree of vegetation is lower, and the fragmentation degree of building landscape is first increased, then decreased, and finally intensified. The proportion of artificial landscape decreases year by year and the trend of fragmentation is obvious. Based on the present situation of spatial structure characteristics of Wulingyuan peak forest landform, optimization methods such as combining centralization with decentralization and improving the quality of artificial landscape ecosystem were put forward.

In order to protect the ecological environment of the peak forest landform in Wulingyuan Scenic Area and maintain the integrity and stability of the peak forest landform, it is necessary to study the optimization method of the spatial structure characteristics of the peak forest landform in Wulingyuan Scenic Area
This paper studies the spatial structure characteristics of peak forest landform in Wulingyuan Scenic Area from three aspects: basic landform characteristics, surface morphology characteristics and geomorphological spatial pattern, and puts forward rational optimization methods to provide basis and reference for the ecological environment protection of Wulingyuan Scenic Area (Jiang, 2017)
Summary
Environment and development have become a common concern in today’s world. Ecosystem is the link between environment and development. Sandstone is a kind of rock formed by weathering, transporting, sedimentation and diagenesis It has the characteristics of low strength, poor weathering resistance and little cementing material. It is the main part of the peak forest landform of Wulingyuan Scenic Area. There are many studies on the peak forest landform of Wulingyuan Scenic Area in Zhangjiajie in China. This paper studies the spatial structure characteristics of peak forest landform in Wulingyuan Scenic Area from three aspects: basic landform characteristics, surface morphology characteristics and geomorphological spatial pattern, and puts forward rational optimization methods to provide basis and reference for the ecological environment protection of Wulingyuan Scenic Area (Jiang, 2017).
