摘　　要：在调查同德县草地退化现状的基础上,综合分析了同德县草地退化的原因,指出了同德县畜牧业可持续发展的策略。同德县的草地退化是自然因素和人为因素共同综合作用的结果。人类活动和气候变化是导致同德县草地退化、区域生态环境恶化的两大因素,鼠虫害对它们产生的影响起了促进作用。只有合理利用和保护天然草地,综合治理退化草地,优化畜牧业产业结构,使草地生态系统步入良性循环,才能使同德县的草地畜牧业协调发展。Based on the current situation of grassland degradation of Tongde County, the causes of grassland degradation were analyzed and sustainable strategies for animal husbandry were provided.

Rodent and pest accelerated the serious situation.
