摘要
长江流域生态环境多样,生物种类与群落类型繁多,已建立的多种类型的自然保护区对保护各类重要生态系统及其环境、拯救濒于灭绝的生物物种及自然遗迹具有重要作用。采用叠图法、数学统计等方法,对长江流域自然保护区的数量、面积、类型、分布、管理等基本情况进行了识别、整理、统计分析与制图,结合长江流域自然保护区分布特点,对长江流域水资源开发利用中生态制约问题进行了初步讨论。至2008年12月长江流域共建立各种类型、不同级别的自然保护区827个,保护区总面积约占长江流域面积的19.9%,高于全国平均水平,长江流域初步形成了类型较齐全、布局较合理、功能较健全的自然保护区网络。长江流域水力资源主要分布于长江上游区,而长江流域自然保护区的重点分布区在长江上游地区,因此长江上游区水电开发需关注现有各级各类自然保护区的生态保护。
In the Changjiang River Basin,there are diverse eco-environment and numerous bio-species and communities.Various types of natural reserve which have been set up have played a crucial role in protecting all kinds of essential bio-environment,and saving extinct bio-species and natural relics.This paper utilized several analytical methodologies such as overlay method and math statistics to recognize and count amount,area,type,distribution and management in this region.Meanwhile,it also discussed bio-restrictive issues on the exploitation.The study shows that up to Dec.2008,there are 827 natural reserves set up in the Changjiang River Basin.The total area accounts for 19.9% of the whole valley,being higher than the national average.A network of natural reserve with various types,sound distribution and strong function has begun to take shape.However,in this region,both water power resources and key natural reserves mainly distribute along the up-stream.Under these circumstances,a conflict between how to make considerable use of water power resources and how to preserve natural reserve arises.Therefore,eco-environmental protection for natural conservation areas with different kinds and at diverse levels should be regarded when water power is exploited among the up-stream region.
