摘要: 中国东北平原西部土地沙漠化, 不仅影响该地区农、牧业和农村经济的发展, 而且已危及人民的生存。该地区科尔沁沙地土地沙漠化每年以1.5%~3.7%递增速度发展。沙漠化的形成有自然和人为两方面原因。该地区沙漠化发展具有脆弱性、可恢复性和可逆性的"三性"特征, 以及生态环境恢复的时间周期。并根据长期以来沙漠化整治试验示范成果, 加以集成优化, 提出一整套符合该区沙漠化综合治理的技术和模式, 有的技术已被当地政府推广和应用。

Abstract: Sandy desertification in Horqin Sandy Land expanded at an annual rate of 1.5%~3.7%. The two causes are related to natural and anthropogenic factors. The sandy desertification of this area is characterized by vulnerability, restorability and reversibility, by which the ecological-environment reversion period has been determined. A set of optimized techniques for comprehensive treatment of sandy desertification are put forward on the basis of much experience, some of which have been applied and popularized by local government.

Key words: western Northeast Plain, sandy desertification, present situation and causes, comprehensive treatment
