双碳背景下黑龙江省土地利用碳源汇时空格局及预测分析
Analysis on the Spatiotemporal Pattern and Prediction of Carbon Sources and Sinks of Land Use in Heilongjiang Province under the Background of Dual Carbon
摘要
Abstract
Land use change has a significant impact on the scale and intensity of regional carbon cycling.This paper uses data such as land use and economic development to analyze the spatiotemporal pattern of carbon sources and sinks of land use in Heilongjiang Province from 2000 to 2020,and uses the CA-Markov model to evaluate land use changes in 2030 and 2060,and predict the spatiotemporal pattern of carbon sources and sinks from 2030 to 2060.The results show that from 2000 to 2020,carbon sources in Heilongjiang Province decreased and carbon sinks increased;the grassland has the highest contribution rate to carbon sinks among different land types,while the farmland has the lowest contribution rate,and the net carbon emissions in Heilongjiang Province first increase and then decrease;the positive correlation between land use carbon emissions between different cities is gradually increasing,indicating that the impact of various regions in Heilongjiang Province on carbon sources and sinks is deepening;according to predictions,from 2000 to 2060,the net carbon emissions from land use in Heilongjiang Province will increase by 6.82×108 t,the overall range of carbon sources has been reduced and emissions have significantly increased,while the distribution range of carbon sinks has significantly expanded.According to the current development trend,Heilongjiang Province can achieve its carbon peak target around 2030.关键词
