摘　　要：基于1990年、2000年、2010年、2020年4期土地利用数据,利用InVEST模型模拟了大庆市4种生态系统服务功能(碳储存、产水量、土壤保持和生境质量)的变化,并对生态系统服务之间的权衡与协同关系进行评估。结果表明:在1990-2020年大庆市草地面积呈减少的趋势,建设用地的面积不断增加;4种生态服务功能均呈先降低再增高的变化趋势,其中土壤保持和产水量变化幅度较大;产水量与其他3种生态系统服务功能之间呈现“权衡”关系,碳储存、生境质量和土壤保持之间存在“协同”关系;林地和水域面积的提升可以提高碳储存和生境质量,各土地利用类型的占比对产水量和土壤保持两种生态系统服务功能影响很小。研究结果对制定合理的土地利用政策,以及提高生态系统服务功能具有一定的积极作用。Based on 4 periods of land use data in 1990,2000,2010 and 2020,the InVEST model was used to simulate the changes in 4 ecosystem service functions(carbon storage,water yield,soil conservation,and habitat quality)in Daqing and relationships of the trade-offs and synergistic among ecosystem services were evaluated.The research results indicate that during the period of 1990–2020,the area of grassland in Daqing showed a de-creasing trend,while the area of construction land continued to increase;all 4 ecosystem services showed a trend of decreasing first and then increasing,with soil conservation and water yield showing larger changes;there was a"trade-off"relationship between water yield and the other 3 ecosystem services;with a synergistic relationship among carbon storage,habitat quality,and soil conservation;the enhancement of forested land and water area can improve habitat quality and carbon storage,and the correlation between the two ecosystem services,namely wa-ter yield and soil conservation,and the proportion of land use types is weak.The research results have a certain positive effect on formulating reasonable land use policies and improving ecosystem service functions.
