Study on Landscape Pattern and Stability of Nanyue Forest

The basis of this research is the 2015 Nanyue forest resource distribution map. At the same time, 8 pattern indices were screened out of its 9 types of forest landscapes. Then, the principal component analysis method was used to analyze the overall forest landscape pattern and use its stability related evaluation models are used to evaluate the stability of various forest landscapes. Subsequently, the researchers used the Kriging interpolation method to study the distribution characteristics of the related stability of the forest landscape, and divided the related stability.The research results show that the forest spot distribution on the south slope is fragmentary, and the forest is mainly composed of coniferous forests such as foreign pine and masson pine. While the forest spot on the northern slope is more integrated, and the forest is mainly composed of bamboo forest, fir forest, sparse forest, and shrub forest and the slope gradually changes to high altitude, broad-leaved forests are distributed in the gully parts on both sides of the mountain. The stability of various forest landscapes has obvious differences, and the differences from large to small are bamboo forest, fir forest, other forests, sparse forests, pine forests, shrub forests, foreign pine forests, broad-leaved forests, and so on. At the same time, the landscape on the north slope is more stable than the forest on the south slope as a whole, and the stability of the forest as a whole is based on the obvious differences between the north and south of the main mountain range of the Hengshan Mountains. The larger the size of the forest patch, the more its overall shape, and the higher the degree of distribution and aggregation, the better the stability of the forest landscape. For a forest landscape with a smaller size, simple shape, and irregular distribution, the stability is low. The results can provide references for forest management and care, ecological planning.
