Investigation and Analysis of the Wild Resources of Poisonous Seed Plants from Yunlong Reservoir Area in Yunnan
摘要
Abstract
In the area of Yunlong reservoir in Yunnan province,there were 103 species of poisonous seed plants which belonged to 50 families and 82 genera.The percentage of the poisonous seed Dlants to the total seed plants in this area was 23.1%,and the percentages of the species number and family number of the poisonous plants to those of the poisonous plants in whole China were 7.9% and 35.7% respectively.The preponderant families of the poisonous plants were Asclepiadaceae, Compositae,Ericaceae, Leguminosae, Lolanaceae and Ranunculaceae,and the preponderant genera were Anemone,Carpesium,Ranunculus and Rhododendron.The most dominant ecotype of the poisonous Dlants was herbage.The species number in the altitude of 2010 m was the maximum,which was also reflected by the maximum abundant index. But some poisonous seed plants diffusely distributed in a wide range of altitudes.After the water-storing of reservoir was fulfilled completely,61.17% of the poisonous seed plants would permanently be submerged.The poisonous plants in the area basically belonged to"Venenous".The main venenous part of the poisonous plants was the whole plant.and it was comnlon that only one oragan of the plant was the most venenous.Basic education,timely establishment of relative law systems,enlarging the artificial planting area and strengthening the management to the market should be the effective measures to protect and exploit the wild resources of poisonous seed plants in the area.This research could provide essential informations for the protection of the entironment surrounding the reservoir and for the scientific safeguard and utilization of the poisonous seed plants.关键词
