摘要/Abstract

摘要： 以甘肃省境内11个主要天然林区作为基本的地理单元,选择天然分布在各林区的中国种子植物特有属的物种丰富度、相对特有性和等级性作为评价指标,对各林区中国种子植物特有属物种多样性进行综合评价,确定出甘肃省中国种子植物特有属物种多样性保护的关键林区,并且运用互补性原理设计出最低保护区域组合及其优先序。分析得出关键保护林区为白龙江下游(白水江)林区、白龙江中上游林区和小陇山林区;最低保护区域组合按其优先序依次为白龙江下游(白水江)林区、白龙江中上游林区、东祁连山林区、小陇山林区和太子山-大夏河林区。

Abstract: In this paper,11 main natural forest areas in Gansu Province were selected as the basic geographic units to identify priority areas for species diversity conservation of spermatophytic genera endemic to China in Gansu Province.Based on the factors of species abundance,relative endemism and hierarchy of the plant species,the species diversities of spermatophytic genera endemic to China in these forest areas were evaluated,respectively,and the critical forest areas were identified.The principle of complementary was applied to design the priority ordination of the conservation areas.The results showed that the critical forest areas should include the lower reaches of Bailong River,the mid-upper reaches of Bailong River and Xiaolong Mountain region.The minimum set of forest areas and its ordination were the lower reaches of Bailong River,the mid-upper reaches of Bailong River,the eastern Qilian Mountain region,Xiaolong Mountain region and the middle-upper reaches of Tao River.
