三峡库区稀有濒危植物异地保护群落设计的初步研究

提出了建造群落舁地保护三峡库区稀有濒危植物的方法。从地点选择、面积确定、物种组成和群落结构等方面探讨了异地保护群落设计的原理和方法。根据对三峡库区及其附近的残存稀有濒危植物群落的调查，选择九宫山自然保护区的一个独特生境，设计了一个面积约３０００ｍ＾２，优势种为珙桐（Ｄａｖｉｄｉａ ｉｎｖｏｌｕｃｒａｔａ）、金线槭（Ｄｉｐｔｅｒｏｎｉａ ｓｉｎｅｎｓｉｓ）、水青树（Ｔｅｔｒａｃｅｎｔｒｏｎ ｓｉｎｒ

A PRELIMINARY STUDY ON THE DESIGN OF A COMMUNITY FOR EX SITU CONSERVATION OF THE RARE AND ENDANGERED PLANTS IN THE THREE GORGE RESERVOIR AREA

A method for constructing a community for ex situ conservation of the rare and endangered plants in the Three Gorge Reservoir Area was proposed.The principles and methods of choosing habitat and determining area,species component and community structure were discussed.According to the results of investigation of the archaic and relict communities of the rare and endangered plants in the Three Gorge Reservoir Area and its adjacent area,a community for ex situ conservation in a unique habitat of Jiugongshan Nature Reserve was designed.The community area was about 30 0 0 m2 and dominant species were Davidia involucrata,Dipteronia sinensis,Tetracentron sinensis and Tapiscia sinensis.There were35species of the rare and endangered plants of the Three Gorge Reservoir Area and more than70 species of other plants in the community.The community structure and the patterns of plants populations will be developed step by step with the growth of the plants in the community.
