Dynamic changes and prediction of carbon storage in the Wulie River Basin based on PLUS—InVEST model
The Wulie River Basin is an essential component of the ecological barrier region of Beijing,Tianjin,and Hebei.Investigating the influence of its land use changes on the spatiotemporal variations of carbon storage can enhance the carbon sequestration contribution in this region.This study employed the PLUS—InVEST model to assess the dynamic changes in carbon storage in the Wulie River Basin from 2000 to 2020 and under three scenarios in 2030(natural development scenario,economic development scenario,and ecological protection scenario).The study's results are as follows:From 2000 to 2020,cropland and grassland decreased,while construction land and unused land increased;The changes in forested areas and water bodies were not significant.The carbon storage in 2000,2010,and 2020 was 39.13×106 t,38.82×106 t,and 38.60×106 t,respectively,showing a decreasing trend over the years.Compared to 2020,the land use changes in the natural development scenario in 2030 were not significant,leading to a relatively small overall change in carbon storage.Under the economic development scenario,the transformation of forested and grassland areas into other land use types resulted in a 5.52%reduction in carbon storage.In contrast,the ecological protection scenario,where cropland and construction land were converted into forest and grassland,led to a 3.40%increase in carbon storage.The ecological protection scenario is more effective in enhancing the carbon storage in the Wulie River Basin.The study's findings can provide a scientific basis for optimizing the land use pattern in the Wulie River Basin and promoting the sustainable development of carbon storage ecological services.
