Study on Optimization Method of Spatial Structure Characteristics of Peak Forest Landform in Wulingyuan Scenic Area

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, as the 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.

“…This type of study has been conducted in Hunan [32], Hubei [33], Guizhou [34], Henan [35], Shandong [36,37], and Shaanxi [38,39]. The second category includes studies based on watershed boundaries, as determined by governmental entities, which have been conducted in the Taihu Lake region [40], the Yellow River basin [41], and the Min River basin [42]. The third category includes topography-based studies, which analyze topics such as the association between the poverty level of villages and topography [43], the influence of ravine topography on village distribution [44,45], and the spatial distribution characteristics of different ethnic villages under complex topographic conditions [46].…”

“…It is the first work in the history of mathematics to systematically discuss geometry by using axioms and methods. Since then, for quite a long time, geometry, as the science of describing the form of things, has been regarded as the only real mathematics and the model of scientific rigor (Gu et al, 2018;Hu et al, 2018;Kong et al, 2018;Zhang, 2020).…”
