四川森林资源的可持续发展

四川森林是我国三大林区之一“青藏高原东部林区”的重要组成部分，该区的森林植被是维系长江流域生态平衡的主要天然屏障。本区森林资源能否持续发展整关长江流域的生态安全。通过对四川森林资源的现状，特点和存在问题的分析表明，四川森林资源丰富，具很高的生物多样性，发展潜力大，是重要的生态屏障，但天然林多、人工林少、林地土中退化严重，资源分布不均，树种单一，森林结构不合理，引种与林副产品的开发也存在许多问题，经济、生态效益差，也是森林植被生态系统的脆弱区之一。要促进该省森林资源的可持续发展，保护其生物多样性，发挥潜力，增强生态屏障作用，必须走以保护为主，多渠道开发，经济与生态效益并重的综合发展之路。

SUSTAINABLE DEVELOPMENT OF FORESTRY RESOURCES IN SICHUAN PROVINCE

Forest resource in Sichuan province is an important component of east part of Tibetan Forest Area, which is one of the three largest forest areas in China. A natural defense in maintaining the ecological balance in the Yangtze River Valley, forest resources in Sichuan province can play an extremely importal role with its sustainable development. Based on analysis on the current status,characteristic and existing problems of forestry resources in this area, we conclude that forest resources in Sichuan province is rather abundant with great potential and high biodiversity. Existing problems include insufficient artificial forest, serious forest soil degradation, unevenly distribution of resources, monotonous species and unreasonable forest structure. Meanwhile more effort should be made on varieties of introduction and exploitation of the forest resources, to preserve the biodiversity and enhance its role in natural defense,and emphasis should be put equally on and economical as well as ecological benefits.
