Quantitative Study on Priority Protection of Rare and Endangered Wild Woody Plants in Xinfengjiang Reservoir Area
In order to strengthen the protection of wild rare and endangered woody plants in Xinfengjiang Reservoir area,based on the field survey data of 9 sample plots in Xinfengjiang Reservoir area,the paper calcu-lated 10 evaluation indicators affecting the priority protection of wild rare and endangered woody plants by using the protection of endangered plants priority law and analytic hierarchy process,the results showed that:(1)There were 147 species of wild woody plants belonging to 53 families and 84 genera in Xinfengjiang Reservoir area,including 7 species of rare and endangered wild woody plants belonging to 6 families and 7 genera;(2)Through the analysis of 10 indexes of endangered coefficient,genetic value coefficient and species value coeffi-cient of 7 wild rare and endangered woodyplants and the comprehensive evaluation value calculation,it was found that the priority conservation order of wild rare and endangered woody plants was Calophyllum membrana-ceum,Diospyros vaccinioides,Erythrophleum fordii,Ormosia semicastrata,Ixonanthes reticulata,Castanop-sis kawakamii,Michelia odora,among them,C.membranaceum,M.odora,E.fordii,D.vaccinioides,O.semicastrata were endangered species,I.reticulata and C.kawakamii were gradually endangered species;(3)By using analytic hierarchy process(AHP),the comprehensive weight calculationof 10 indicators showed that the priority protection order of rare and endangered wild woody plants was C.membranaceum,D.vaccinioides,O.semicastrata,E.fordii,I.reticulata,M.odora,C.kawakamii;(4)According to the pri-ority protection level,7 wildrare and endangered woody plants,such as Calophyllum membranaceum,D.vaccinioides,E.fordii,O.semicastrata,I.reticulata,C.kawakamii,M.odora,belong to the highest pri-ority protection plants of Class I.
