| Abstract: | Based on field investigation,this paper made quantitative studies to assess the sequence of emergent protecting demand for national protected plants distributed in Shenonngjia Nature Preserve in Hubei.“the Coefficient of Endangerment”“the Coefficient of Lost Genetic Diversity”and “the Coefficient of Value” were used to determine the priority of conservation.The results showed that of the 14 assessed plants,4 is in the first grade protection,5 in the second and 5 in the third.Moreover,some effective measures of conservation have been put forward. |
