土壤盐渍化遥感监测研究进展综述

土地盐渍化是干旱、半干旱地区由于人类不合理的开发土地资源活动和脆弱的生态环境相互影响而引起的土地退化问题,也像沙漠化一样是当今世界重要的环境和社会经济问题.因此,提高土壤质量、促进农业持续发展、保护环境是已成为世界21世纪土壤科学的主题.本文首先对国内外土壤盐渍化研究的进展进行了全面地描述,然后介绍了对土壤盐渍化遥感监测研究方法、研究目的及其研究焦点,同时对土壤盐渍化研究中急待解决的研究课题及其有效的研究手段进行了总结,从而为进一步拓展和深化土壤盐渍化研究的内容及水平打下了牢固的基础.

Research Progress and Summary of Remote Sensing Monitoring of Soil Salinization

Soil salinization is the land degradation problem which is mainly caused by inter-effecting between the unreasonable human activity and frail eco-environments in the arid and semi arid regions. Like desertification, it is also main worldwide social and environmental problem. It becomes one of the disasters which worsen unceasingly for human economical development and ecological improvement. Hence, main subjects in 21century of soil science are improvement in soil quality, promotion in sustainable agricultural development and protection in environment. This article mainly presents and summarizes domestic and foreign research progress, remote sensing monitoring methods, research objects, and research focus of soil salinization. At the same time, effective study methods for solving urgent needed soil salinization problems is given, thereby it can be given in a firm bases for developing and deepening the content and levels of soil salinization study.
