摘　　要：【目的】在“三生空间”视角下,定量分析鹰潭市土地利用转型及其生态环境效应,为协调市域国土空间规划、土地政策实施、生态环境保护提供借鉴。【方法】基于鹰潭市2010、2014、2018年3期土地利用现状数据,按“生产—生活—生态”土地利用主导功能进行分类,运用土地利用转移矩阵、生态环境质量指数模型、土地利用变化生态贡献率等方法,定量分析2010—2018年鹰潭市土地利用转型的时空演变格局、生态环境效应。【结果】(1)2010—2018年,鹰潭市“三生空间”用地结构发生显著变化。土地利用转型主要表现为生态用地减少,生产、生活用地增加。土地转出面积最多的为林地,共计3860.60 hm^(2),转入面积最多的为农业生产用地,共计1581.72 hm^(2)。(2)生态环境质量指数呈现波动的趋势,在2010年为0.6055、2014年为0.5962、2018年为0.5980,生态环境质量指数在2010—2014年间降低,但在2014—2018年间上升。(3)2010—2018年,鹰潭市的生态环境质量同时存在生态改善与恶化两种趋势,最终抵消呈现出一定的下降趋势,林地大量转为建设用地是生态环境恶化的主要原因,农业生产用地等生态环境质量较低的生产用地转为林地和草地是生态环境改善的主要因素。【结论】鹰潭市生态环境自2014年开始得到有效改善,但总体看来生态环境恶化的趋势大于生态改善的趋势,定量研究鹰潭市过去9年的土地利用转型及其生态环境效应,能为鹰潭市的生态建设提供数据、理论支撑。针对生态用地减少等问题,鹰潭市未来要科学规划土地转型的方向,合理划定生态保护红线,以江西省“生态文明建设试验区”为主导,协调区域经济与生态的同步发展。[Objective]From the perspective of“production-living-ecological space”,this paper quantitatively analyzes the land use transformation and its eco-environmental effects in Yingtan City,so as to provide reference for coordinating the land space planning,land policy implementation and eco-environmental protection.[Method]Based on the current land use data of Yingtan City in 2010,2014 and 2018,which are classified according to the dominant function of“production-life-ecological space”,the temporal and spatial evolution pattern of land use transformation and ecological environment effect in Yingtan City from 2010 to 2018 are quantitatively analyzed by using land use transfer matrix,eco-environmental quality index model and ecological contribution rate of land use change.[Result](1)From 2010 to 2018,the land use structure of“production-living-ecological space”in Yingtan City changed significantly.The transformation of land use was mainly manifested in the reduction of ecological land and the increase of production and living land.The largest area of land transferred out was woodland,with a total of 3860.60 hm^(2).The most area transferred in was agricultural production land,with a total area of 1581.72 hm^(2).(2)The eco-environmental quality index showed a fluctuating trend,which was 0.6055 in 2010,0.5962 in 2014 and 0.5980 in 2018.The eco-environmental quality index decreased from 2010 to 2014,but increased from 2014 to 2018.(3)From 2010 to 2018,the ecological environment quality of Yingtan City had two trends of ecological improvement and deterioration at the same time,and the final offset showed a certain downward trend.The main reason for the deterioration of the ecological environment was that a large number of forest land was converted to construction land,and the main factor for the improvement of the ecological environment was that the production land with low ecological environment quality such as agricultural production land was converted to forest land and grassland.[Conclusion]The ecological env
