Abstract: In view of the unclear interactive coupling relationship between land use and ecological environment along the Grand Canal, taking 4km along the Cangzhou section of the Grand Canal as the study area, a coupling coordination model is established to evaluate the relationship between land use and ecological environment in the study area by using the land use data of 2014, 2018 and 2020 and the ecological environment data evaluated by RSEI model. The results show that from 2014 to 2020, within 4km along the Cangzhou section of the Grand Canal, the main land use types are cultivated land and construction land, accounting for more than 95%, and the ecological space along the Grand Canal is seriously occupied. The overall ecological environment quality index RSEI shows a downward trend, with a decrease of 9.5%. Forest land and grassland make positive contributions to the ecological environment, and construction land makes negative contributions to the ecological environment. By 2020, the coupling relationship between land use and ecological environment is extremely uncoupled, and the development of land use lags behind, indicating that the contradiction between land development and utilization and ecological environment is further intensified, and the unreasonable use of land has a negative impact on the ecological environment.

Key words: 4km along the Cangzhou section of the Grand Canal, land use, ecological environment quality, coupling coordination analysis

摘要： 文中针对大运河沿线土地利用与生态环境交互耦合关系不明确等问题,以大运河沧州段沿线4km范围为研究区,利用2014,2018和2020年3期的土地利用数据和RSEI模型评价的生态环境数据,建立耦合协调度模型评价研究区土地利用与生态环境的关系。结果表明:2014-2020年间,大运河沧州段沿线4km范围,主要土地利用类型是耕地和建设用地,两者占比达95%以上,大运河沿线生态空间挤占严重;生态环境质量指数RSEI整体呈降低趋势,降幅达9.5%,林地、草地对生态环境有积极的贡献,建设用地对生态环境有消极贡献;至2020年,土地利用与生态环境的耦合关系表现为极不耦合发展土地利用滞后型,说明土地开发利用与生态环境之间的矛盾进一步加剧,土地的不合理利用对生态环境造成了消极影响。
