Priority area assessment for species diversity conservation of spermatophytic genera endemic to China in Gansu Province

Abstract

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.
