湖北珍稀濒危野生植物物种多样性就地保护之评议

Evaluation and Proposal to In-situ Conservation of Species Diversity of the Precious,Rare and Endangered Wild Plants in Hubei

摘要:

研究表明，湖北省２２个野生植物和森林生态系统类型自然保护区现已就地保护了５５种国家第一批公布的珍稀濒危野生植物，占全省总数６２种的８８．７％，在对珍稀濒危野生植物物种多样性就地保持现状进行综合评价的基础上，提出了合理调整和局自然保护区，大力发展自然保护小区，自然保护点和禁伐区，就地保护和其它保护手段相结合等建议。

Abstract:

This paper deals with evaluation and proposal to the present state of in-siteu conservation of the species diversity of the precious,rare and endangered wild plants in Hubei province. The results show: 1. 55 species hanve been in-situ protected by 22 nature reserves of hubei,accounting for 88.7% of their tolal ones (62 species). 2.22 nature reserves play an important role in the in-situ conservation of these species diversity,especially in their communities. 3. A few key species (7 species) haven't been in-situ conservated,such as pinus dabeshanensis,Torreya jackii and Heptacodicum miconioides,etc:Some important species haven't been in-situ conservated as good as possible,e. g. Amentotaxus argotaenia and Manglietia patungensis, etc. 4. Some endangered plants should be ex-situ conservated instead of in-situ conservation,e. g. Taiwanin cryptomerioides, Magnolia sieboldii,M. amoena,Torreya jackii,and Sinojackia xylocarpa,etc. 5. Add justing the distribution of the nature reservas,setting up more nature reserves in many different regions, expanding the area of some nature reserves,developing much rnore small nature reserves, nature protected spots,and forbidden zones,as well as taking ex-situ conservation,are the rugent tasks now.
