Research on the impact of spatial and temporal changes in ecological product value in Hebei Province based on land use changes.

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.
