| 摘 要： | 从江河源区气候、地理及生态系统功能的特殊性入手,对江河源区一系列自然资源、生态环境问题进行分析和评述.指出江河源区生态环境问题非常复杂,生态环境建设应该从保护生态系统入手,维持已经建立的江河源自然保护区模式,国家持续性投资于生态补偿、恢复以及相应的科学研究是江河源区生态环境长久改善的基础.重视文化教育,科技培训及推广,能给江河源区生态环境建设带来持久性的效果.在退化草地生态系统上建立家庭牧场模式的草地农业体系,改变退化草地生态功能,使之成为高效的饲草供应基地,是实现极度退化草地生态恢复和经济作用的最佳措施.江河源区生态环境威胁日趋严重,因此问题的解决需要我国政府、人民以及科技力量的共同努力.

| Abstract: | Problems in natural resources,ecology and environment in headwater areas of Yangtze and Yellow Rivers in Qinghai-Tibetan Plateau were analyzed from climate,geology and eco-system functions.These problems were quite complicated and eco-construction should start with eco-system protection,continue to maintain the pattern of conservation region in the headwater area.It is must be emphasized that the government invest to ecological supplement,restoration,and some research,which is the fundamental for the ecological construction.Education,technical training and extension could guarantee the effect of eco-environment improvement.Establishing family pasture system on degraded grassland and converting its ecological function to feed supply base are the best way to rehabilitate severely degraded grassland and economy.The serious situation of eco-environment in headwater area needs government,people and technology work together to deal with. |
