西部干旱地区生态环境脆弱,土壤盐渍化严重破坏了国民经济的生产和生态环境的平衡,为了解决这一问题,对干旱区盐渍化的这一问题进行系统的研究是非常必要的。以新疆塔里木盆地南缘于田县为例,利用近30年来遥感影像,深入分析以于田为代表的干旱区盐渍化土壤的光谱特征及其空间特性,借助PCI图像处理平台,进行盐渍化土壤专题信息的提取,分析得出盐渍化动态演变的趋势。
In western arid region, the ecological environment is fragile and soil salinization severely undermines the balance between the production of the national economy and the ecological environment. To solve this problem, it is necessary to conduct a systematic study on the salinization of arid areas. Taking Yutian County in the southern margin of Tarim Basin, Xinjiang as an example, the spectral characteristics and spatial characteristics of salinized soils, represented by Yutian, were analyzed based on remote sensing images for nearly 30 years. With the aid of PCI image processing platform, Extraction of soil thematic information, analysis of the trend of salinization dynamic evolution.
