摘　　要：为推进盐碱区粮食安全与生态环境协同发展,本研究以吉林省西部典型盐碱区为例,基于2000、2010、2020年3期土地利用数据,运用土地利用转移矩阵和InVEST模型,分析研究区土地利用的生境质量时空动态演变特征,划分生态修复功能区。结果表明:2000—2020年研究区土地利用类型以耕地为主,占比超过60%,耕地和裸地呈扩张趋势,草地面积逐渐缩减;20年间生境质量等级为优的面积增加361.74 km^(2),生境质量等级为差的面积增加1080.54 km^(2),研究区整体生境质量差异增大。基于生境质量和陆地生态系统服务价值等级划分重点修复区、适度修复区、自然修复区和适度开发区,针对性地提出修复策略。研究表明,土地利用类型转化导致研究区总体生境质量两极分化差异显著,未来在提升盐碱化地区粮食产能的同时,还要兼顾生境质量,注重协调粮食生产和生态保护两者之间的关系。To promote the coordinated development of food security and eco-environmental resources in saline-alkali region,this study took the typical saline-alkali region in western Jilin Province as an example,based on three periods of land use data in 2000,2010,and 2020,using the land use transfer matrix and InVEST model,analyzed the spatio-temporal dynamic evolution characteristics of habitat quality of land use in the study area,and divided the ecological restoration areas.The results showed that:from 2000 to 2020,cultivated land was the main type of land use in the study area,accounting for more than 60%,cultivated land and bareland showed an expanding trend,and grassland area gradually reduced.Over the past 20 years,the area with excellent habitat quality grade increased by 361.74 km^(2),and the area with poor habitat quality grade increased by 1080.54 km^(2),which increased the overall difference of habitat quality in the study area.Based on the habitat quality and the service value of terrestrial ecosystem,the key restoration areas,moderate restoration areas,natural restoration areas and moderate development areas were divided,and the restoration strategies were put forward.The study showed that the land use type transformation led to significant polarization of the overall habitat quality in the study area.In the future,while improving the food production capacity in saline-alkali region,we should also take into account the habitat quality and pay attention to coordinating the relationship between food production and ecological protection.
