Study on Characteristics and Differences of Spatial Structure of Forest Parks in Chongqing

Abstract

Spatial features of forest parks in Chongqing, the object of study, have been analyzed based on the nearest neighbor index, geographic concentration index, imbalance index, Gini coefficient, kernel density, among others, and the ArcGIS analysis software in order to achieve a better ecological support function of forest parks in protecting the natural ecological environment and driving the sustainable economic and social development of Chongqing. The results show that forest parks in Chongqing are randomly distributed on the whole, those in the main urban area distributed with weak agglomeration, those in the urban agglomeration in the Three Gorges Reservoir area in northeast Chongqing and in the urban agglomeration in the Wuling mountainous area in southeast Chongqing evenly distributed; forest parks in Chongqing, with poor balance of distribution, are mainly distributed in the main urban area; their kernel density is high in the center and low at both wings, and the sequence in terms of kernel density is: main urban area > urban agglomeration in the Three Gorges Reservoir area in northeast Chongqing > urban agglomeration in the Wuling mountainous area in southeast Chongqing.
