Analyze the changes in land use and the spatial evolution characteristics of ecological product value in Hebei Province, understand the driving factors that affect the value of ecological products, and aim to promote the sustainable use of land resources and promote local economic development. This paper investigated the changes in land use and landscape patterns in Hebei Province from 2010 to 2022, and used the improved equivalent factor to account for the value of ecological products, used the global Moran's I index, high/low clustering index,and the hotspot analysis method to explore the characteristics of spatial and temporal changes in the value of ecosystem services in different districts and counties of the study area, and finally used geodetector to explore the influence factors of land use change on the spatial and temporal changes in the value of ecological products in Hebei Province. value of ecological products in Hebei Province. The following conclusions were drawn: (1) Land use in Hebei Province is dominated by farmland, forests, grasslands and impervious surfaces, accounting for about 95% of the area of Hebei Province. (2) From the accounting results, the value of ecological products in Hebei Province during the study period shows a trend of rising, then falling and then rapidly rising, with the value of ecological products in Hebei Province amounting to 256,640,551,000,000 Yuan in 2010, and 488,748,000,000 Yuan in 2022, with a rise of close to 47.4892%. In addition, the high-value area of ecological product value is concentrated in the northern part of Hebei Province, with the city of Chengde and Zhangjiakou as the main areas of the dam plateau, and the low-value area is concentrated in the plains of Hebei Province. Damshang Plateau area, mainly in Chengde City and Zhangjiakou City, and the low-value area is concentrated in the Hebei Plain area. (3) When exploring the factors influencing the spatial and temporal changes of ecological product values in Hebei Province due to land use changes, population density, slope and elevation with large q-values are the main factors influencing the ecological product values in Hebei Province. In addition, in terms of factor interactions, there are two types of two-factor enhancement and nonlinear enhancement in the interaction of factors influencing the high and low values of ecological products in Hebei Province as a result of land use change. From 2010 to 2022, the land use and landscape patterns in Hebei Province have changed significantly, and the value of ecological products has also changed continuously. It is necessary to put forward a strategy to improve the value of ecological products based on the change of land use in Hebei Province, to promote the transformation of the economic development in the direction of ecologically friendly and sustainable development, and to realize the benign cycle of economic growth and environmental protection.
分析河北省土地利用变化及生态产品价值的空间演变特征,了解影响生态产品价值的驱动因素,旨在促进土地资源可持续利用,推动地方经济发展。本文研究了2010—2022年河北省土地利用及景观格局变化,运用改进后的当量因子法核算生态产品价值,采用全局莫兰指数、高低聚类指数和热点分析方法探究研究区不同区县生态系统服务价值的时空变化特征,最后运用地理探测器探究河北省土地利用变化对生态产品价值时空变化的影响因素。得出以下结论:(1)河北省土地利用以农田、林地、草地和不透水面为主,约占河北省面积的95%。(2)从核算结果来看,研究期内河北省生态产品价值呈先上升、后下降、再快速上升的趋势,2010年河北省生态产品价值为25664.0551亿元,2022年为4887.48亿元,上升近47.4892%。此外,生态产品价值高值区集中在河北省北部,以承德市和张家口市的坝上高原地区为主,低值区集中在河北省平原地区。(3)在探究河北省土地利用变化引起生态产品价值时空变化的影响因素时,q值较大的人口密度、坡度和海拔是影响河北省生态产品价值的主要因素。此外,在因素交互作用方面,土地利用变化导致河北省生态产品高低值影响因素交互作用存在双因素增强和非线性增强两种类型。2010—2022年,河北省土地利用及景观格局变化显著,生态产品价值也不断变化。有必要基于河北省土地利用变化提出提升生态产品价值的策略,推动经济发展向生态友好型和可持续发展方向转变,实现经济增长与环境保护良性循环。
