摘要
本文采用生态经济学的理论和方法 ,揭示了中国北方牧区草原雪灾背后的生态经济问题 ,中国北方草原牧业生态经济系统的主要特点是结构脆弱 ,功能低下。随着人口的高速增长 ,经济系统对生态系统的干预大大超过生态系统的自我调节能力 ,不合理的人类经济活动破坏了生态经济平衡 ,使草原生态系统严重退化 ,牧业经济系统陷于困境 ,系统抗灾能力降低。在缺乏有效生态经济管理的情况下 ,生态效益的外部性将不可避免地使生态经济系统矛盾更加尖锐化 ,系统运行陷入双轨恶性循环 。
This article disclosed the eco-economic problems behind prairie snow disaster on north pasturing area with eco-economic theories and methods.The characteristics of prairie eco-economic system in north pasturing area are fragile eco-structure and low system function.The degree of interference of economic sytem to the eco-system exceeded self-regulation power of ecosystem with the rapid increase of population Irrational human activities destroyed eco-economic balance,and caused the prairic eco-economics degenerated and anima husbandry got into a hobble,reduced the eco-economic system the resistibility on natural disasters.Under the situations of inefficicent eco-economic management,the externality of eco-economics will inevitably aggravate conflict of eco-economic system,which will get into vicious circles on double-tracks,and then block the economic development of pasturing area.
