摘　　要：为了研究宁夏沙坡头国家级自然保护区的土地利用类型变化对碳储量时空分布的影响,利用该保护区1990—2020年土地利用数据,运用斑块生成土地利用模拟(PLUS)模型和生态系统服务和权衡的综合评估(InVEST)模型研究保护区碳储量对土地利用类型变化的响应,预测2030年保护区不同情景下的土地利用类型及碳储量的变化。结果表明:1990—2020年保护区内未利用地面积持续减少,草地和耕地面积增加;未利用地向草地转化以及草地的碳密度较大,导致草地碳储量增大;2030年保护区在自然变化情景和生态保护情景下的碳储量分别增加2.39×10^(5)、1.05×10^(5)t,而在耕地保护情景下的碳储量则减少0.1×10^(5)t,自然变化情景更有利于提高保护区的碳储量。To study the effect of land use type change on temporal-spatial distribution of carbon storage in Shapotou National Nature Reserve of Ningxia,land use data from 1990 to 2020 were used,and patch-generated land use simulation(PLUS)model and integrated valuation of ecosystem services and trade-offs(InVEST)model were used to study the response of carbon storage in the research region to the changes in land use types and carbon storage under different scenarios in 2030.The results show that the unused land area in the research region continuously decreases,while the area of grassland and cultivated land increase from 1990 to 2020.The conversion of unused land to grassland and the higher carbon density of grassland led to the increase of grassland carbon storage.In 2030,the carbon storages of the research region under the natural change scenario and ecological protection scenario increase by 2.39×10^(5) t and 1.05×10^(5) t,respectively,while the carbon storage under the cultivated land protection scenario decreases by 0.1×10^(5) t.The natural change scenario is more conducive to improving the carbon storage of the research region.
