摘  要:
土地盐碱化是造成土壤退化、土地资源短缺和生态环境恶化的主要原因之一。为此,在遥感和GIS技术支持下,以1990和2000年Landsat TM/ETM遥感影像为主要数据源,并辅以地形图等资料,提取哈尔滨市对青山镇典型区土地盐碱化动态信息;同时,分析了土地盐碱化的自然和人为驱动因素,为防治土地盐碱化提供决策依据。

摘  要:
One of the major reasons of soil degradation,land resources shortage and ecological environment worse is land sali-alkalization. Supported by RS and GIS technology, the dynamic information of land sali-alkalization in the typical zone of Duiqingshan town, Harbin city is extracted from two sequences of classified landsat TM/ETM remote sensing images, dating from1990 to 2000, with the combination of relief map and investigation results. The physical and human being driving factors are further analyzed for decision making in prevention and harness of land sali-alkalization of Duiqingshan town.
