摘  要：
以中国和蒙古国克氏针茅针茅草原为研究对象,采用生产性能和生态学两种方法评价草原退化程度。生产性能评价结果显示,四季游牧和两季轮牧草原均呈中度退化,四季轮牧草原呈重度退化,定居放牧草原呈极度退化;生态学综合评价结果表明,四季游牧草原呈轻度退化,两季轮牧草原呈中度退化,四季轮牧草原呈重度退化,定居放牧草原呈极度退化。

摘  要：
Using the method of performance evaluation and ecological evaluation the degradation degree of Stipa krylovii steppe in China and Mongolia was evaluated.The results of performance evaluation showed that the four-season grazing pasture in Mongolia and two-season rotational grazing pasture in China showed moderate degradation,four-season rotational grazing pasture and grazing pasture of inhabited pasturage showed heavy degradation and extreme degradation in China and Mongolia.In contrast,ecological evaluation showed that four-season grazing pasture in Mongolia was in light degradation,two-season rotational grazing pasture,four-season rotational grazing pasture and grazing pasture of inhabited pasturage showed the same result as performance evaluation.The study suggested that ecological evaluation can evaluate degradation degree of grassland more comprehensively and systematically.
