- Abstract:
-
National protected area is the core part of China's nature reserve system and plays a major role in China's natural ecological protection pattern. The spatial pattern characteristics of 113 national protected areas and 4 world natural Heritage sites in Guizhou were analyzed by using the methods of Nearest Neighbor index,Kernel Density estimation and Spatial Superposition. The results show that:(1)national protect areas present the agglomerative distribution. The single class of protected area land distributes discretely in Guizhou Province. The kernel density area of the protected areas is characterized by two types of combined distribution: point-like and banded. The high-density area is located in the northwest of Zunyi,southwest of Guiyang,central southeast of Guizhou and the border area between Tongren and the north.(2)The overlap rate of state-level protected area in Guizhou Province is 44%,and there are three high-density areas,which are the central part of Southeast,the border area between north Southeast and Tongren,and the northwest of Zunyi. There are 13 types of overlapping types,of which the overlapping types of most frequent occurrence are nature reserve and forest park,and the overlapping type with the largest area is nature heritage and nature reserve.(3)The national protected area mainly distributes in karst landforms,and the national key ecological function area is the important distribution and main gathering area of the protected area in Guizhou Province. The results of this study can provide scientific reference for the integration and optimization of nature reserves and the construction of regional ecological civilization in Guizhou Province.
