Quantitative assessment of priority for rare and endangered plants in Wanchaoshan Nature Reserve of Hubei
摘要
Abstract
Based on sample-plot survey and sample-line survey, rare and endangered plantsresurces in Wanchaoshan Nature Reserve of Hubei Province was investigated, and the priority conservation of rare and endangered plants was quantitatively analyzed by using threatened confficient, genetic coefficient, species value coefficient and comprehensive evaluation value.The results showed that there were 47 species of rare and endangered plants belonging to 34 genra of 44 families;9 species was ranked as the first grade for conservation priority, 23 species as the secondgrade,12 species as the third grade, and 3 species as the fourth grade, according to the distribution characteristics of rare and endangered plants.It is found that the distribution of the rare and endangered plants is relatively concentrated, and at the altitude of 900-1 600 m, the species and the number of rare and endangered plant species were the most.This research result is more realistic and effective, which provides a scientific basis for the management of the protected area to make the protection plan of the rare and endangered plants in the area, and makes it more efficient and effective in guiding the protection of the area.关键词
