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。
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.
