秦巴山区生态屏障建设的初步探讨

A Preliminary Study of Building Ecological Defense System in Sichuan Qinba Mountain Areas

秦巴山区是长江上游生态屏障的重要组成部分,四川秦巴山区具有丰富的自然和人文资源,是四川北部和东北部重要的生态屏障,提供了重要的生态系统服务,但对四川秦巴山区有限的研究影响了对这一区域生态屏障建设重要性的认识,该区域还是典型的"丰富自然资源与落后经济矛盾体"。对区域、生态系统服务功能和生态屏障的片面认识、区域分割和缺乏系统规划等是该区域生态屏障建设面临的主要问题,解决这些问题是建设四川秦巴山区生态屏障的关键。

The Qinba Mountain areas is an important component o{ the ecological defense system of the upper and middle Yangtze River. The Qinba mountain areas is enriched in natural and cultural resources which plays an important role in ecological system while acting as an important ecological defense for northern Sichuan province and northeaster Sichuan province. However,lacking of research and understandings toward such areas has led to insufficient awareness of building ecological defense system in such areas. In addition,the Qinba mountain areas is a typical paradox between abundant natural resources and backward economic development. Facts like insufficient understanding towards ecosystem services and ecological defense system,segmentation,no systematic planning are major problems that hinder ecological defense construction which are highlighted as the pivotal issue of the construction of the ecological defense system in Qinba mountain areas.
