大别山区生态系统碳储量时空变化特征
Spatiotemporal variation characteristics of carbon storage in Dabie Mountain Area Ecosystem
摘要
Abstract
Study of the spatio-temporal variation relations between the land use change and the carbon storage in Dabie Mountain Area is important for the protection of regional ecosystem and the sustainable development of carbon storage.Based on the remote sensing data of land cover in Dabie Mountain Area from 2000 to 2020,the temporal and spatial changes of different ecosystem was analyzed from three aspects:annual change rate,dynamic degree,and transfer matrix.The main carbon storage changes in the past 20 years were investigated with InVEST model.The results showed that:(1)The cultivated area continued to decrease from 2000 to 2020,while the industrial and mining land for urban and rural residents increased rapidly.The ecosystem dynamic change index(LC value)of the whole Dabie Mountain Area was 0.13 percent.The cultivated land was mainly converted into the industrial and mining land for urban and rural residents.(2)The carbon storage in 2000,2010 and 2020 in the research area was 24540.06×104 t,24504.99×104 t,24368.2×104 t respectively.Over the past two decades,the carbon storage had reduced 171.86×104 t,with a much higher magnitude decrease in the second decade.(3)The transformation of land use pattern was the primary cause of the variation of the carbon storage.The decrease of the carbon storage was mainly due to a shift from the high carbon-intensive cropland and forestland to the low carbon-intensive industrial and mining land in urban and rural residents.关键词
