中文摘要	Floristic Quality Assessment (FQA) is proposed as a new method to assess floristic integrity. In the present study, we use both the conventional method broadly adopted in the USA and a new one proposed herein to assess the floristic quality of the Jiuding Mountain. For the application of the FQA, each plant species was assigned an integer from 0 to 10 termed coefficient of conservatism (C) based on its global distribution area. The coefficient shows the degree of fidelity of each plant species to the flora of the west slope of the Jiuding Mountain and represents a rank based on its distribution area. Those species receiving a C value of 0-1 are distributed all over the world, those receiving a C value of 2-3 mostly in tropical areas, and those receiving a C value of 4-6 broadly in temperate areas. Species with C values of 7-8 are endemic to China and those with coefficients 9-10 are restricted to the Hengduan Mountains or even endemic to the Jiuding Mountain. Based on the fact that different plant species show different relative importance values (IV), the new method estimates the weighted averages for the coefficient of conservatism called the weighted mean coefficient of conservatism . The floristic quality index (FQI) was then derived from C or C-w, native species richness (N) and non-native species (A). As expected when using the new method, the dominant species of the communities obtained different Cs, which resulted in different C (w)s and FQI(w)s as compared to the conventional method.
