摘要:
 自然保护地空间格局及影响因素的研究对于构建黄河流域以国家公园为主体的自然保护地体系具有现实意义。以黄河流域青甘宁片区国家级自然保护地为案例地，基于2003-2021年306个自然保护地点数据，借助ArcGIS 10.8空间分析工具，运用核密度分析、标准差椭圆等方法，从类型、密度等方面，对研究区域内自然保护地空间分布的时空格局进行研究；运用空间分析、相关性分析和地理探测器对影响因素进行探讨。结果表明，1)青甘宁黄河流域自然保护地空间结构类型为凝聚型和随机型；2)从分布密度上看，呈现出以省会及重点城市为核心，以黄河为轴的点状集聚与线状扩张并存的演变态势；3)自然保护地空间格局方向分布变化不显著，方向与黄河在该区域的流向一致；4)影响流域自然保护地空间分布的因素依次为社会因素（0.626 0）＞自然因素（0.579 7）＞经济因素（0.541 3），影响因素存在双因子增强和非线性增强。社会因素成为首要因素与青甘宁地区的自然人文环境密切相关，影响因素在共同作用下最终形成了自然保护地空间格局。
Abstract:
 The study of the spatial pattern of nature reserves and the influencing factors is of practical significance 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 Basin 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 extending 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-factorial 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.
