Studies on Floristic Elements of Rare and Endangered Plants and National Conservative Plants in Yunnan

According to the red book of Chinese plants(Vol.1) and the national important wild conservative plants list(List 1) which was issued by the State Council in August of 1999, there are 83 families, 152 genera, 191 species of rare and endangered plants and national conservative plants in Yunnan. Based on deepgoing investigation and detailed floristic statistics, the floristic elements and the geographical distribution are analyzed here. The results have shown that the floristic elements have such features as ancient origin, obvious endemism, complicated elements, wide connection with other flora and uneven geographical distribution. In addition, some suggestions about conservation are put forward at the end of this paper.
