小型湖泊湿地自然保护区功能区划探讨

以安徽沱湖省级自然保护区功能区划的实践,探讨了小型湖泊湿地自然保护区的功能区划分思想及方法,以期为相似生态功能区划提供参考。文章提出把连接水陆异质景观生态系统的特殊单元的生态交错带,作为保护区中发挥重要作用的功能区域。在生态交错带内进行生态恢复,保护景观多样性,并使之成为连接核心区斑块的廊道。通过生境多样性、生态系统多样性的保护及景观连接度的提高达到生物多样性保护的目的。同时,通过设立保护性经营区缓解发展与保护的矛盾。

Discussion on the function zoning of minitype lake-wetland natural reserve

The practice of function zoning of the Anhui Tuohu provincial natural reserve is introduced,and the thought and method of function zoning of minitype lake-wetland natural reserve are discussed. The ecotone that is a special unit joining different aquatic-territorial landscape ecosystem is regarded as an important functional part of the natural reserve. Through ecological recovering and landscape diversity conservation, the ecotone becomes the corridor of joining the core area patches. The target of biodiversity conservation is realized by protecting habitat diversity and ecosystem diversity and by promoting landscape connectivity. At the same time, the protecting development area is set up to weaken the contradiction of development and protection. The case study is beneficial to the similar ecological function zoning.
