自然保护区面积确定方法探讨

自然保护区面积确定问题是自然保护区建设和管理以及自然保护区学中迫切需要解决的问题.该文分析了自然保护区面积确定问题的复杂性,阐述了岛屿生物地理学、种群生存力分析、最小可存活种群、有效种群理论、群落或生态系统稳定性等理论或观点在自然保护区面积确定中的应用和不足,并对解决自然保护区面积确定问题提出了一些可能的途径,包括集合种群理论、景观生态学理论的应用,加强种群生存力分析应用的研究,对某些自然保护区可以考虑种子雨与群落演替规律,有时也可以考虑动物行为学的特征等. 

Approaches for setting the minimum area of nature reserve

It is urgent to resolve the problem of setting the minimum area of nature reserve, either for nature reserve construction and management or for the nature reserve science. However, this problem has not been resolved up to date because of its complexity. This paper discussed the complexity of this problem, and expounded the application and shortcomings of the theory of island biogeography, population viability analysis, minimum viable population, effective population theorg and the stability of community or ecosystem in setting the minimum area of nature reserve. Afterwards, some possible ways helping to resolve this problem were suggested, such as the application of metapopulation theory and landscape ecology, reinforcing researches on the application of population viability analysis in setting the minimum area of nature reserve. Dispersal of germs and community succession rules as well as the characteristics of animal behavior can be taken into account in some nature reserves.
