Spatial Evolution Characteristics and Influencing Factors of the Nature Reserves in the Yellow River Basin——A Case Atudy of the Qinghai-Gansu-Ningxia Region
摘要
Abstract
The study of the spatial pattern of nature reserves and the influencing factors is of practical sig-nificance for the construction of a nature reserve system in the Yellow River Basin with national parks as the mainstay.Taking national nature reserves in the Qinghai-Gansu-Ningxia region of the Yellow River Ba-sin as an example,and based on 306 nature reserve data points from 2003 to 2021,we used ArcGIS 10.8 spatial analysis tools,kernel density analysis,standard deviation ellipses and other methods to investigate the spatio-temporal patterns of nature reserve distribution in the study area,considering factors such as type and density.GIS spatial analysis,correlation analysis and geographic detectors were used to explore the influencing factors.The results showed that 1)the spatial structure types of nature reserves in the study area are agglomerative and random.2)In terms of distribution density,an evolving pattern coexisting with point aggregation and linear expansion is observed,centred on provincial capitals and key cities and ex-tending along the Yellow River axis.3)The directional distribution of the spatial pattern of nature reserves shows no significant changes,and the direction is consistent with the flow direction of the Yellow River in the region.4)The factors influencing the spatial distribution of nature reserves in the basin are ranked as follows:social factors(0.626 0)＞natural factors(0.579 7)＞economic factors(0.541 3).There is a bi-fac-torial enhancement and a non-linear enhancement of the influencing factors affecting the spatial pattern of nature reserves.Social factors becoming the primary ones that are closely related to the natural and human environment of the region,and the spatial pattern of the nature reserve is finally formed by the joint action of the influencing factors.关键词
