摘　　要：人类改造自然的速度和强度在不断提高,对区域生态环境的可持续发展构成了重大威胁。基于Modis卫星影像数据,利用遥感生态指数探究了赣州市2001—2015年生态环境质量时空变化特征及其对人类活动的响应,并利用趋势分析法研究了像元尺度上赣州市生态环境质量和人类活动强度的空间变化趋势。结果表明:(1)2001—2015年间,赣州市的生态环境质量呈波动上升趋势,且在所有的区县中,章贡区的RSEI最低,多年平均值为0.518;(2)人类活动强度和耦合协调度在市中心发达地区呈下降趋势,在市中心周围呈上升趋势;(3)人类活动强度与生态环境质量之间表现出负相关关系,人类活动的持续增强,使得耦合协调度呈现先增后减的趋势,表明人类活动强度的提高不会一直对区域环境产生积极影响。The speed and intensity of human transformation of nature are increasing,which poses a major threat to the sustainable development of the regional ecological environment.Based on the Modis satellite image data,the remote sensing ecological index was applied to explore the temporal and spatial variation characteristics of the ecological environment quality in Ganzhou City from 2001 to 2015 and its response to human activities,and the trend analysis method was explored to analyze the ecological environment quality of Ganzhou City at the pixel scale.and the spatial trend of human activity intensity.The results showed that:(1)From 2001 to 2015,the ecological environment quality of Ganzhou City displayed a fluctuating upward trend,and among all districts and counties,Zhanggong District had the lowest RSEI,with a multi-year average of 0.518;(2)The intensity of human activities and the coupling coordination degree shows a downward trend in the developed areas of the city center,and an upward trend around the city center;(3)There was a negative correlation between the intensity of human activities and the quality of the ecological environment.The trend of increase and decrease indicates that the increase in the intensity of human activities would not always have a positive impact on the regional environment.
