基于RS的安达市土地盐碱化面积提取研究
Research on extraction of land salinization area in Anda City based on RS
摘要
Abstract
Taking Landsat remote sensing images as the main data，with the support of RS and GIS, applying the methods of unsupervised classification and visual interpretation of human-computer interaction, the area of salinized land in Anda city in different periods was obtained quantitatively, and the cause of the development and driving force of the saline-alkali soil was analyzed in Anda City. The results showed that after the land improvement，the area of mild，moderate and severe saline-alkali soil in Anda City decreased by 1.78%，1.24% and 2.56% respectively, and the total area of saline-alkali soil decreased by 87830.46 hm2.The formation of saline-alkali soil in Anda Area was mainly related to climate factors and human factors. The development of saline-alkali soil wad mainly influenced by both natural and geographical factors and human factors. After banning grazing and planting rice to improve the soil and other measures，the saline-alkali land generally developed slightly.关键词
