Based on sample-plot survey,rare and endangered plant resources inYerengu Nature Reserve of Hubei province was investigated, and the priority conservation of rare and endangered plants was quantita-tively analyzed by 5 synthetical indicators like threat coefficient, genetic coefficient, species value coeffi-cient ,comprehensive evaluation value, protection status coefficient and breeding difficulty coefficient, and 15 individual indicators.
