渭河干流陕西段沿岸碳汇生态服务供需格局时空差异
Spatiotemporal differences in the supply and demand pattern of carbon sequestration ecological services along the Shaanxi section of the Wei River mainstream
摘要
Abstract
Carbon storage module in InVEST model and ArcGIS were employed to analyze the regional variations and supply-demand matching of carbon sequestration items of ecosystem services.The land use,carbon density,and carbon emission data of 2010,2015,and 2020 in 22 districts and counties in Shaanxi Province were selected for the analysis.The results show that the total supply of carbon seques-tration services decreased from 24.6614×106 to 23.8044×106 t from 2010 to 2020;whereas the demand increased from18.9881×106 to29.0765×106 t,exhibiting a significant spatiotemporal mismatch.From 2010 to 2020,the carbon sequestration per unit area decreased by 44.49 t/km2,and the carbon emission per unit area increased by 523.76 t/km2,which aggravated the imbalance between supply and demand of carbon sequestration services.The deficit of carbon sequestration services in the study area continued to spread,especially in the central urban agglomerations which showed an obvious deficit tendency caused by excessive carbon emission.This study can provide a support for the management of regional ecological development planning,optimization and coordination of regional resource allocation,as well as implemen-tation of regional carbon compensation.关键词
