2015-2020年黑龙江省大兴安岭地区蓝绿空间土地利用变化及其对碳储量的影响
Land Use Changes in Blue-green Space and Their Impacts on Carbon Storage in Daxing'an Mountains of Heilongjiang Province from 2015 to 2020
摘要
Abstract
[Objective]The changes in blue-green space land use were predicted and their impacts on carbon storage in Daxing'an Mountains were analyzed in order provide scientific strategic for realizing the"dual-carbon"goal guidance references.[Methods]Based on land utilization data for Daxing'an Mountains in 2015 and 2020,the driving factors of a binary logistic regression test were introduced into the PLUS model to predict the blue-green space land utilization pattern in 2030.The InVEST model was coupled with the results to analyze the impact of changes in blue-green space on carbon storage.The main driving land types of blue-green space causing changes in carbon storage were quantified and verified.[Results]① Blue-green space continued to grow from 2015 to 2030.Forest land increased over this time period,accounting for more than 60％of the blue-green space transfer,indicating that forest land held an absolute advantage.② From 2015 to 2020,blue-green space accounted for 96.52％of the total area of carbon storage growth space.Carbon storage for the natural development,blue-green space protection,and rapid urban development scenarios in 2030 were 1.459 4× 109 t,1.483 1 × 109 t,and 1.464 7× 109 t,respectively,mainly due to the transfer of a large amount of non-blue-green space to forest land and grassland.Protection of blue-green spaces had the most obvious effect on the increase of carbon storage.③ The degree of aggregation of forest land,grassland,and water areas in the blue-green space was significantly and positively correlated with carbon storage.Forest land and grassland were the first and second most dominant types of carbon storage changes.[Conclusion]Excellent ecological policies should be promoted in the future to protect the blue-green space and to improve the structural integrity of forest land and grassland so as to achieve the"dual-carbon"strategic goal in the Daxing'an Mountaions.关键词
