论自然保护与资源开发的策略

物种保护的根本途径是保护其生境，生境的完整性遭到破坏则物种将趋于灭绝［１，２］。不少国家的政府及非政府组织正投入巨资设置保护区试图将至少部分生物多样性资源加以永久保存［３］，但这些目标的达到往往是基于如下假设：即保护区将不受干扰、原封不动的加以保存并与经济活动及周围环境难以达成任何形式的妥协。然而越来越多的证据表明，在全球范围遭受人类干扰的背景下无论是保护区内还是保护区外的生境均将趋于退化，因此现行建立保护区的模式并不能有效阻止生物多样性灾难性的损失［４］。特别对于发展中国家，人口、资源、环境的…

Habitat Renewal and Habitat Mitigation - on the Strategy of Natural Conservation.

The conservation of species requires preservation of natural habitats,where the integrity of natural habitats has been severely disturbed and species goes extinct. All natural habitats are continuing to decline both inside and outside of reserves. Habitat change is partly a natural process (e.g., succession), but human activities have accelerated the process so that natural rate of renewal is insufficient to maintain natural habitats. This paper provided concept, methods of habitat renewal, habitat mitigation and their implication to protection and exploitation of natural resource. We argue that our only resourse, in light of these scenarios, is to adopt a new conservation strategy that considers the importance of habitat renewal and habitat mitigation in addition to habitat preservation. Accordingly, in our management decision, we must not only choose the size of area to preserve ,but also the size of area to balance habitat loss with habitat renewal or habitat mitigation. Finally, we explored the application of habitat renewal and habitat mitigation in regional sustainable development of Liaohe Delta wetland.
