中文摘要	由于气候干旱加之超载过牧使得草地退化严重,不仅使内蒙古希拉穆仁草原区生态环境恶化,而且也严重威胁京津地区生态安全.因此,治理退化草地及防止草地进一步退化迫在眉睫.内蒙古希拉穆仁草原地处干旱荒漠草原区,在多年的过度放牧压力下,草地植被、土壤均严重退化,水土流失严重.但这时草地还没有遭到根本破坏,还未产生沙化、盐碱化现象.终止过度利用令其自然修复,2、3年以后即取得明显效果.观测研究表明,经连续3年封禁自然修复,到第3年样方干草量增加到4.6倍,草高增加到9.2倍,盖度增加到1.6倍.草群结构和土壤改善,草地水土保持功能大大增强,水土流失减少20%.
英文摘要	Due to the drought climate and overgrazing, the grassland degraded severely, which not only influenced local environment, but also threatened ecology safety of areas around Beijing and Tianjin. Urgent control of degraded grassland and prevention of further deterioration was needed. Xilamuren grassland in Inner Mongolia was located in arid desert grassland area. After years of overgrazing, the grassland vegetation and soil degraded severely and the soil erosion was serious. But the degradation was not fatal yet, the grassland has not become desertification and salinization. So enclosing the grassland and letting it rehabilitate naturally, obvious effect would acquire after just 2 or 3 years. The related observation and research indicated that the yield of the grassland increased to 4.6 times, grass height increased to 9.2 times and coverage increased to 1.6 times after successive three years’ enclosure and natural rehabilitation. The grass community structure and the soil improved ecologically. The conservative function of the grassland strengthened greatly. The soil erosion decreased by 20%.
