Abstract: Based on the richness,evenness and species diversity indicators,this paper analyzed diversity level of 10 kinds of resource plants,such as edible plants,oil plants,wild forage plants,medicinal plants,wood plants,tanning plants,aromatic plants,fiber plants,environmental protection plants,honey plants in Qinghai Datongbeiheyuanqu Nature Reserve.The result showed that:medicinal plant richness was the highest (R=49.85033),the second was environmental protection plants,while honey plants minimal;environmental protection plants evenness was the highest (J=0.064914),the second was medicinal plants,nectar source plant the lowest;medicinal plants diversity index was the highest (H′=0.362267),the second was environmental protection plants,while honey plants minimal.Thus,the diversity of medicinal plant resources was higher than others;its utilization prospect was the best in Qinghai Datongbeiheyuanqu Nature Reserve.

Key words: Qinghai Datongbeiheyuanqu Nature Reserve, resource plants, diversity
