This study aims to investigate the contradiction between the growing demand for ecosystem services and the degradation of these services due to urbanization. Within the context of ecological civilization construction and the "dual carbon" goals, research on the carbon sequestration function of terrestrial ecosystems is particularly significant. Utilizing land-use data from 2000 to 2022, this study employs Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model's Carbon module to estimate the carbon stock in Pingshan County, using it as a representative example. Geological environmental factors, including elevation, slope, aspect, and degree of relief, were considered with the distribution of geological hazard points and the implementation of relevant policies. Both qualitative and quantitative analyses were undertaken to examine the variations in carbon stock in Pingshan County. The results demonstrate a consistent increase in carbon stock from 2000 to 2022. The geological environment exerts the most significant influence on carbon stock, followed by land-use types, while geological disasters have the least impact. This paper studies the changes in carbon storage and its driving factors in Pingshan County from multiple perspectives. It not only provides theoretical basis and new ideas for the ecological environment protection of Pingshan County, enriching the research results on the carbon cycle of terrestrial ecosystems, but also offers guidance for promoting human-land harmonious development, advancing ecological civilization construction, and achieving sustainable development.
本研究旨在探讨生态系统服务需求不断增长与城市化导致这些服务退化之间的矛盾。在生态文明建设和“双碳”目标的背景下，陆地生态系统碳固存功能的研究尤为重要。本研究利用2000年至2022年的土地利用数据，以平山县为例，采用生态系统服务与权衡综合评估（InVEST）模型的碳模块来估算碳储量。考虑了包括海拔、坡度、坡向和地形起伏度在内的地质环境因素以及地质灾害点的分布和相关政策的实施情况。采用定性和定量分析方法来研究平山县碳储量的变化情况。结果表明，2000年至2022年碳储量持续增加。地质环境对碳储量的影响最为显著，其次是土地利用类型，而地质灾害的影响最小。本文从多个角度研究了平山县碳储量的变化及其驱动因素。它不仅为平山县的生态环境保护提供了理论依据和新思路，丰富了陆地生态系统碳循环的研究成果，还为促进人地和谐发展、推进生态文明建设和实现可持续发展提供了指导。
