Assessment and Planning of Land Use Change and Carbon Storage in Hunan Province Based on the PLUS-InVEST Model
Land-use transformation is also one of the main ways causing carbon emissions.In China,from 2000 to 2020,the construction land increased by about 94000 square kilometers,leading to a reduction of 350 million tons of carbon in the national soil carbon reservoir.Ear-ly layout and planning of land resources can help avoid repeated changes in land use that contribute to carbon emissions.Based on the PLUS model,the simulation of land-use data in Hunan Province in 2020 yielded a Kappa coefficient of 0.84 when compared to the actual land-use data,indicating high simulation accuracy.The simulation extended to predict land use in Hunan Province for 2030 under ecological,natural,and economic scenarios.Using the InVEST model,the spatial distribution of carbon storage under different scenarios in Hunan Province in 2030 was simulated.In the ecological scenario for 2030,the largest land area is covered by forests at 125255.74 square kilometers,with the highest carbon storage of 3136255749 tons.In the economic scenario,construction land covers the most area at 7792.31 square kilometers,with the smallest carbon storage of 3130186347 tons.Based on the simulated land-use data and carbon storage distribution data for different scenarios in Hunan Province in 2030,which provides data support for future land-use planning in the province.
