资源型城市土地利用和生态系统服务功能的时空变化与耦合效应分析
Analysis of Spatial-temporal Evolution and Coupling Effects of Land Use and Ecosystem Services in a Resource-based City
摘要
Abstract
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.关键词
