摘要

摘要: 利用1986年（TM）和2001年（ETM）卫星遥感影像数据和RS-GIS集成技术，对松嫩平原盐渍化土地的现状、程度和发展趋势进行了量化分析.结果表明，这15年中，松嫩平原盐碱地面积增加了21.7112×104 hm2，每年增加1.45×104 hm2，年平均增长率为1.4%.其中轻度盐渍化土地增加8812 hm2，年平均增长0.16%；中度盐渍化土地增加3.8306×104 hm2，年平均增长0.64%；重度盐渍化土地面积增加了16.9994×104 hm2，年平均增长了4.2%.气候变暖，降水减少，人为活动增强是盐渍化程度加重的主要驱动力.

Abstract: Landsat TM (ETM) images acquired in 1986 and 2001 and the RS-GIS integrated technique are adopted to quantitatively analyze the present situation, degrees and developing trend of salinized-alkalized land in Songnen plain. It is concluded that, during the 15 years, the area of salinized land has increased 21.7112×104 hm2, averagety 1.45×104 hm2 per annum, with average annual increase rate of 1.4%. Among them, the salinized areas in light-degree, mediate-degree and heavy-degree have increased respectively by 0.8812×104 hm2, 3.8306×104 hm2 and 16.9994×104 hm2, with average annual increase rate of 0.16%, 0.64% and 4.2% respectively. The main drives for the increase of salinization are the warming climate, reduced precipitation and increased human activities.
