Abstract

Forests are important carbon sinks in ecosystems. The process of converting forests to other land-use types will lead to a decrease in the carbon sink potential of ecosystems. It is of research significance to explore the mechanism of the impact of land use change on the spatial and temporal evolution of forest carbon stocks. In this paper, we analyzed the land use change and its spatial distribution pattern based on the land use data of Fujian Province. We then used the inVEST model to estimate the impact of land use change on the carbon stock in Fujian Province. The results show that the proportion of forested land in Fujian Province from 2000 to 2020 is 35.02%. Moreover, the area of forested land is mainly shifted to cropland and artificial land, which have a lower carbon sink potential than that of forested land. The top three carbon stocks in Fujian Province in 2000 and 2020 for each land-use type are forested land, cropland, and artificial land in that order. The most important source of carbon stock in Fujian Province is forest land (84.01%). It is followed by cultivated land (12.84%). The carbon stock in the inland area (high carbon stock) and the coastal area (low carbon stock) of Fujian Province had a decreasing and increasing trend, respectively. The transfer of forest land to cropland dominated the decrease of carbon stock in seven cities of Fuzhou, Sanming, Quanzhou, Zhangzhou, Ningde, Longyan, Nanping, and Ningde in Fujian Province. In comparison, the transfer of cropland to cultivated land dominated the decrease of carbon stock in the two cities of Xiamen and Putian in Fujian Province.
