摘　　要：【目的】探讨克里雅河流域土地利用功能转型对生态环境产生的影响。【方法】基于1990、2000、2010、2020年4期土地利用遥感监测数据,定量分析了克里雅河流域生产、生活和生态功能空间的时空演变特征,以及功能空间相互转移的生态环境效应。【结果】1990~2020年,克里雅河流域生产空间和生活空间增加,而生态空间减少,土地利用功能转型主要表现为草地生态用地与其他生态用地之间的转化和其他生态用地与农业生产用地之间的转化;1990~2020年,克里雅河流域生态环境质量指数呈现先减后增的变化趋势。变化较大是中游和下游区;1990~2020年,其他生态用地转化为草地生态用地和水域生态用地是克里雅河流域生态环境质量提升的主要原因,二者贡献率达97.28%;相反,农业生产用地、草地生态用地和水域生态用地向其他生态用地的转入是流域生态环境质量退化的主要原因,三者贡献率达负的98.50%。人口与经济因素、农业发展因素是克里雅河流域三生空间变化的主要驱动力。【结论】克里雅河流域生态环境质量虽有所好转,但生态环境问题依旧突出,需要加强对农业生产用地、草地生态用地及水域生态用地的治理与保护。【Objective】 The study aimed to explore the impact of land use transformation on ecological environment in the Keriya River Basin.【Method】 Based on four periods of land use remote sensing monitoring data in 1990,2000,2010 and 2020,The spatial and temporal evolution characteristics of production,living and ecological function spaces in the Keriya River Basin and the eco-environment effect of function space transfer were quantitatively analyzed.【Result】 From 1990 to 2020,the production and living space in the Keriya River Basin increased and the ecological space decreased,and the transformation of land use functions was mainly manifested by the transformations between grassland and other ecological land,and between other ecological land and agricultural production land.From 1990 to 2020,the ecological environmental quality index in the Keriya River Basin showed a downward trend firstly and then a upward trend.The biggest change occurred in the midstream and downstream areas.From 1990 to 2020,the improvement of the ecological environment quality in the Keriya River basin could be mainly attributed to the transformation of other ecological land into the grassland and the water ecological land,and the contribution of both reached 97.28%.On the contrary,the conversion of agricultural production land,grassland ecological land and water ecological land to the other ecological lands was the main reason for the deterioration of ecological environment quality in the basin,and the contribution rate of the three was 98.50%.Population,economic factors and agricultural development factors were the direct driving forces for the change of Production-LivingEcology spaces in the Keriya River basin.【Conclusion】 Although the eco-environmental quality of Keriya River basin has improved,the eco-environmental problems are still serious and it is necessary to strengthen the governance and protection of agricultural production land,grassland ecological land and water ecological land.
