摘　　要：赣南流域受稀土矿山开采影响,水土污染较为严重,局部生态环境有恶化的趋势,文中利用1995年TM影像、2000年TM影像、2006年TM影像和2013年Landsat8 OLI影像进行解译分析,以濂江流域为例进行土地利用变化分析.选取合适的研究区影像分类方法,通过4期影像的分类成果解译出流域内不同时期的土地分布利用,分析濂江流域土地利用类型面积随时间变化情况,并通过土地变化转移矩阵,研究各种土地利用类型变化去向,实现土地的动态监测,提供濂江流域内土地的利用变化信息,有助于实现资源的合理利用.结果表明:研究区矿区开采范围趋势是先增后减,在2006年前后研究区采矿用地面积达到最大峰值,2013年采矿用地面积有所降低,而林地的面积变化趋势刚好与采矿用地的面积变化趋势相反,其原因与当地的经济发展与政府的相关政策有直接联系.Influenced by rare earth mining, the water and soil pollution in South Jiangxi basin is very serious,thus the local ecological environment has a tendency of deterioration. Taking Lianjiang River basin as an example, this study analyzes the land use change with the TM image in 1995,TM image in 2000,TM image in2006 and Landsat8 OLI image in 2013.With the four image classification results, the study analyzes the situation of land use types of Lianjiang River drainage area changes over time by adopting the appropriate classification method of the study area, analyzes the whereabouts of various land use changes through land use transfer matrix, realizes the dynamic monitoring of land use and provides the land use change information,which contributes to the reasonable use of land resources. The conclusions are as follows： the trend of mining area scale increased at first and then decreased; the area of mining land reached maximum peak around 2006 and decreased in 2013; the land change curve trend of forest was just the opposite with mining land area,which had a direct relation with the local economic development and government policies.
