On the basis of the remote sensing images of 1989, 1999 and 2009, integration of ICA-TSVM classification and visual interpretation was used to do monitoring research on soil salinization at the level of over medium in the region of central Asia. The results showed that soil salinization in the region of central Asia mainly distributes in Turkmenistan, Kazakhstan and western part of Uzbekistan. In the view of quantity, soil salinization becomes more and more severe year by year, especially in Uzbekistan,there is a greater degree of change. With local conditions, the cause of soil salinization has been analyzed from the aspects of natural environment factor and social economy factor. And some prevention measures such as a sound irrigation systems, establishment of modern drainage systems, planting salinity plants have been proposed to provide as scientific basis for the future soil salinization control and development in this region.%以1989、1999、2009年3期NOAA遥感影像数据为基础,采用ICA-T-SVM分类和目视解译结合的方法,对中亚地区中度以上级别的土壤盐渍化进行监测研究分析.结果显示,中亚地区的盐渍化主要集中在土库曼斯坦、哈萨克斯坦以及乌兹别克斯坦的西部地区;从数量上看,盐渍化程度在逐年加重,特别是乌兹别克斯坦变动程度较大.结合当地情况,从自然环境因子和社会经济因子2方面分析了盐渍化成因,提出建立完善的灌溉系统,建立现代化排水系统,种植耐盐碱植物,增施农家肥等防治措施.
