摘要
本文主要论述了我国当前草地生态失调和草地超载过牧的情况和问题,并针对这种情况提出了依法管理草地的有关措施。
There are about 400 million ha of grassland in china. Grassland is the base of animal hus bandry development and the enviroment to mankind existing. However, serious deterioration on grassland has occured and the problems of ecosystem imbalance have appeared because of various reasons.Desertification, Soil erosion, and precipitation decreasing are getting serious in large areas. The author recognized that the basic reason for the ecological imbalance is Overgrazing Caused by heavy stocking rate. For example, a sheep unit had only 0.87 ha of pasture in 1988 in Inner Mongolia. The influence of the orergrazing on grassland is wide and grave. The overgrazing not only damages the viability of grasses, but also Changes the physical property of soil. Therefore, author considers that the key of maintaining ecological balance is controlling stocking rate. So the grassland must be managed by scientific way according to grassland laws, the stipulation of appropriate stocking rate, and the establishment of rotational system in order to protect grassland ecosystem.
