摘要
在分析甘孜州草地退化特征的基础上,利用因子分析和灰色关联分析的原理与方法建立了草地退化的社会经济驱动力模型,结合理塘县的实际对草地退化的主要社会经济驱动因子及驱动力的大小进行了研究。结果表明,牲畜数量、人口数量、产业结构、草地保护政策执行情况、草场围栏面积以及牧民人均纯收入是草地退化的主要社会经济驱动因子。在此基础上,探讨了防止草地进一步退化的对策与措施。
Based on the analyses of grassland degradation characteristics in Ganzi Prefecture, using principle and method of factor analysis and grey incidence analysis established the socioeconomic driving model of grassland degradation, Combined with the actual situation of Litang County, the authors studied the main socioeconomic driving factors and the size of driving forces. The result showed that main socioeconomic driving forces of grassland degradation were the number of livestock, population, industrial structure, and implementation of protecting grasslands＇ policies, enclosure grassland areas and annual net income per capita in pasture.
