摘要:
土壤盐渍化是影响干旱区绿洲生态环境稳定的重要因素。以新疆焉耆盆地开都河下游灌区为例，基于GIS平台，以两个时期的遥感影像数据作为主要信息源，对研究区的土壤盐渍化现状、程度与分布特征进行遥感解译和实地调查。研究表明：近20年来研究区的土地盐渍化数量和程度有所减缓。盐渍化土地面积由1990年的1928.90km2下降到2008年的1513.40km2，盐渍地面积减少了415.50km2，平均每年减少21.87km2，年减少率为1.13%；土壤盐渍化程度有所减缓，但土壤盐渍化依然对区域的生态环境安全与绿洲经济的可持续发展构成威胁。
Abstract:
Soil salinization poses a substantial threat to the eco-environmental stability of the oasis irrigation areas. The downstream of Kaidu River irrigation areas located in the Tarim Basin, Xinjiang as an example, based on GIS platform, taking the remote sensing images in 1990 and in 2008 as the main information, by interpreting the images with combination of the field survey, the status quo, degree and distribution characteristics of the soil salinization are analyzed. Some results are concluded as follows: the saline land has decreased in area and degree in the studied period of 20 years. Area of saline land has decreased from 1928.90 km2 in 1990 to 1513.40 km2, and the decreased area is 415.50 km2, decreased by 21.87 km2 per year on average, and the decrease rate is 1.13% per year. The degree is weakened, but the saline land has constituted a serious threat to the ecosystem environment and oasis economic development, thus, more concern should be given to it.
