| 摘 要： | 吉泰盆地间我省自然灾害频发区，农作物产量水平居全省最低。以吉安地区为研究区域，在遥感、地理信息系统和全球定位系统的技术支持下，利用美国陆地资源卫星Ｔｍ资料，采用野外调查和计算机监督分类相结合的方法对吉安地区的农田、有林地、居民区和水体进行解译。根据历年各乡（镇）双季水稻和粮食总产资料，采用ＧＩＳ中的空间分析方法从分类后的农田中提取吉泰盆地中低产田面积及其分布状况。分类结果可为吉泰盆地生态环境治理和

| Abstract: | Natural disasters always happen in Jian-Taihe Basin. In this region, crop yields are lower than other places in Jiangxi Province. On the support of the techniques of RS, GIS and GPS, based on the landsat satellite Tm data, combined the field investigation with supervised classification in computer, the areas and distributions of forest landform, farm land, residential places, waste land and ground water resources can be interpreted. According to the double rice and total grain yields, the areas of middle and lower crop yield and their distributions in this region can be gotten with space analysis method of GIS. Such results can be applied in planning and improving the ecological environment of Jian-Taihe Basin. |
