摘要
玛纳斯河流域作为新疆重要的绿洲农业耕作区,生态环境脆弱,探讨土地利用转型及其生态环境效应对该区国土空间优化以及乡镇可持续发展有着重要意义。基于“生产-生活-生态”空间主导功能,分析玛纳斯河流域土地利用功能转型和生态环境效应演变,探讨该区域生态环境效应分异机制。结果表明:(1)2010—2020年,玛纳斯河流域主要发生生态空间向生产空间和生活空间的转出。(2)玛纳斯河流域整体生态环境质量指数从0.29变化为0.27,农业生产空间侵蚀生态空间带来的生态环境负面影响逐渐增强。(3)地形因素和气候因素是玛纳斯河流域生态环境效应变化的主导因子,因子间的交互作用共同驱动流域土地利用转型,导致玛纳斯河流域生态环境质量格局复杂。
As a significant desert oasis agricultural area in Xinjiang,the Manas River Basin has a fragile ecological environment.Understanding land use changes and their environmental impacts is crucial for optimizing land use and promoting sustainable development in this region.Based on the spatial function classification of“production-living-ecological,”this study analyzes the shifts in land use capabilities and the evolution of eco-environmental effects in the Manas River Basin,while exploring the mechanisms underlying the differentiation of eco-environmental impacts.The results indicate that:(1)From 2010 to 2020,there is a prominent conversion of ecological space into production and living spaces in the Manas River Basin.(2)The eco-environmental quality index of the Manas River Basin declines from 0.29 to 0.27,with the negative environmental impacts of agricultural production space encroaching on ecological space gradually intensifying.(3)Topographic and climatic factors are the primary drivers of changes in eco-environmental effects in the basin,and the interactions among these factors propel land use transformations,leading to a complex pattern of eco-environmental effects in the Manas River Basin.
