天祝县天然草地退化成因及对策分析
Degradation causes and sustainable development of grassland in Tianzhu County
摘要
Abstract
230 000 ha grassland accounted for 58.76%of the total grassland area have degraded at Tianzhu County in 2010. At present, the county's natural grassland is still degrading by a rate of 13 300 ha per year. The grassland degradation was caused by both natural factors and human activities. However, over- grazing was a main reason for natural grassland degradation from light to heavy. Therefore, comprehen sive countermeasures based on controlling grazing capacity and resolving conflicts between grass and live- stock were put forward for natural grassland in the paper, which can help sustainable development of Tianzhu natural grassland and offer technical references for areas of Qilian Mountains on rational utilization of grassland resources and control of degradation.关键词
