2000-2030年云贵高原碳储量和生境质量时空格局演变
Evolution of spatial and temporal patterns of carbon stocks and habitat quality on the Yunnan-Guizhou Plateau during 2000-2030
摘要
Abstract
The karst geological conditions of the Yunnan-Guizhou Plateau have led to serious rocky desertification and fragile ecological environment.Evaluating the ecosystem service function of the region can help to improve ecological environment problems.Based on the InVEST model and PLUS model,the carbon stock and habitat quality of the Yunnan-Guizhou Plateau from 2000 to 2030 are quantitatively evaluated.Combined with natural resource zoning,the temporal and spatial variation characteristics and driving factors of carbon stock and habitat quality in the region from 2000 to 2030 are analyzed.The results show that from 2000 to 2030,the average carbon stock of the Yunnan-Guizhou Plateau is 7.323×109 t,showing a downward trend over the years,with a total reduction of 0.471×109 t.Spatially,it was characterized by high in the west and low in the east.The highest fourth-level zoning was the subdivision of the northern part of Chuxiong in the eastern part of Lijiang City.The land type with the highest contribution to carbon stock was the forest land(>60%),followed by cultivated land(>28%).The factor with the strongest explanatory power for the spatial differentiation of carbon stocks was elevation,and the factor with the strongest interaction was land use and slope direction.From 2000 to 2030,the average habitat quality of the Yunnan-Guizhou Plateau is 0.755,showing a downward trend over the years,with a total reduction of 0.016.Spatially,it was characterized by high in the west and low in the middle and east.The highest fourth-level zoning was the subdivision in the west of Lijiang City and the southeast of Nujiang Lisu Autonomous Prefecture.The habitat quality of forest land is the highest,with an index of 0.83.The research results reveal the evolution law and distribution pattern of carbon stock and habitat quality on the Yunnan-Guizhou Plateau,which can provide a scientific basis for the ecological environment construction of the region.关键词
