Spatiotemporal distribution characteristics and spatial network construction of national nature reserves in China
摘要
Abstract
This study examines 474 national nature reserves in China from 1956 to 2023,utilizing kernel density estimation to analyze their spatiotemporal distribution patterns.A social network analysis model is then employed to measure the attributes of these reserves and to propose integrated protection strategies.The findings reveal the following.(1)The evolution of China's national nature reserves can be categorized into four distinct stages:Pre-liminary exploration,vigorous development,slow development,and consolidation and improvement.This devel-opment has resulted in a spatial pattern characterized by large and scattered reserves in the west,and small and clustered reserves in the east.(2)Topological analysis reveals that the nodes within the national nature reserve network exhibit strong cohesion,small-world characteristics,and a prominent"core-periphery"effect.(3)The network's spatial pattern demonstrates significant heterogeneity among protection clusters,forming a"triangu-lar"framework for reserve aggregation,with key vertices located in the middle and lower reaches of the Yangtze River,the Northeast Plain,the Changbai Mountain area,and the Qinghai-Xizang Plateau.Based on the natural en-dowments and geographic conditions of these reserve clusters,we propose corresponding integrated protection strategies from the perspective of the association network,aimed at providing guidance for the integration and op-timization of nature reserves.关键词
