摘　　要：基于2000、2010、2020共3期绥棱县土地利用数据,利用InVEST模型测算2000—2020年绥棱县碳储量变化,并通过FLUS模型与Fragstats模型模拟出3种场景下绥棱县景观格局及碳储量变化。结果表明:1)2000—2010年期间,绥棱县景观破碎度增加,蔓延度下降;碳储量呈现上升趋势,共增加1.076×10^(5)t。2010—2020年期间,景观破碎度加剧,景观异质性增加;碳储量下降趋势明显,共减少0.609×10^(5)t。2)3种场景下景观异质性均有增加,生态保护场景相较其他2种场景有所缓解,自然发展场景与农田保护场景下碳储量均呈现下降趋势,分别为18.051×10^(6)、18.059×10^(6)t,其中生态保护场景下碳存储量有所增加,为18.116×10^(6)t,相较自然发展场景高出6.08×10^(4)t。因此,通过分析绥棱县不同场景下土地景观格局变化特征,进而计算碳储量变化,为绥棱县国土空间规划提供参考依据,其中生态保护场景更有利于城镇发展,故应遵循低碳城区开发模式,以人居环境为导向,合理组织土地资源区划,推进生态绿色城区建设。Based on the land use data of Suiling county in 2000,2010 and 2020 changes in carbon stock in Suiling county from 1990 to 2018 were calculated using the InVEST model,and changes in landscape pattern and carbon stock of Suiling county under three scenarios were simulated using the FLUS model and the Fragstats model.Taken together,these all provide suggestions for the green and low-carbon development of Suiling county.The results showed that,1)Suiling county mainly benefited from the protection of forest resources during the period from 2000 to 2010,with increased landscape fragmentation,decreased spreading degree and increased carbon stock(1.076×10^(5) t in total).While Suiling county showed intensified landscape fragmentation,increased landscape heterogeneity,and decreased carbon stock(0.609×10^(5) t in total)during the period from 2010 to 2020.2)Landscape heterogeneity increased in all three scenarios,while ecological protection scenarios changed slightly compared with other two scenarios.Carbon stock in natural development scenarios and farmland protection scenarios showed a downward trend,with a value of 18.051×106 t and 18.059×10^(6) t,respectively.Ecological protection scenarios showed increased carbon stock of 18.116×10^(6) t,which was 6.08×10^(4) t higher than that of natural development scenarios.In conclusion,by analyzing the characteristics of land landscape pattern changes in different scenarios in Suiling county,the changes of carbon storage were calculated.Among them,the ecological protection scenario was more conducive to urban development.We should follow the low-carbon urban development model,take the living environment as the guide,rationally organize the division of land resources,and promote the construction of ecological green urban areas.
