三峡库区湖北段川明参的生境特征及保护对策

川明参为中国特有种子植物，现仅知分布于我国四川和湖北二省内的局部地区，在三峡库区也有其分布。根据在三峡库区湖北段内的实地调查情况，描述了川明参的分布、生境特点和群落学特征。分析表明，三峡工程的兴建对川明参的影响主要来自工程建设和移民开发的间接影响。针对川明参的生长状况、分布特点和工程影响的程度，提出几点保护建议：（１）加强宣传教育，帮助人们合理利用川明参；（２）建立川明参保护点；（３）开展川明参的生物生态学研究。

A PRELIMILARY STUDY ON THE ECOLOGICAL CHARACTER ISTICS AND CONSERVATION STRATEGY OF CHUANMINGSHEN (Chuanminshen violaceum)AT HUBEI SECTOR OF THE THREE-GORGE RESERVOIR REGION

ChuanMingShen(Chuanminshen violaceum)is a Chinese endemic seed plant sp ecies.It is currently known to distribute at some local sites in Sichuan and Hubei Provinces,including the Three-Gorge Reservoir Region.In this paper,the characteristics of distribution,habitat and community of C.violaceum are described according to the field condition aquired in Hubei sector of the Three-Gorge Reservoir Region in a recent investigation.The analysis suggests that the influence of the Three-Gorge Project to C.violaceum mainly comes from the indirect effect due to the construction,the resettlement of local people as well as the economic exploitation.The advice on the conservation of C.violaceum is given in terms of its distribution,growth and the degree of engineering effect on it :(1)Enhance publicity and education to help people properly utilize this plant;(2)Set up a conservation site for it ;(3) Begin its biological and ecological study.
