长江流域珍稀濒危和国家重点保护植物综述

Summary of rare and in imminent dangerous plants as well as the plants mainly protected by government in the Yangtze basin

根据众多研究者对长江流域19省(自治区、直辖市)珍稀濒危植物和国家重点保护植物已有研究结果,结合1991年《中国植物红皮书(第一册)》和1999年8月国务院批复的《国家重点保护野生植物名录(第一批)》,对长江流域珍稀濒危植物和国家重点保护植物资源进行了统计与分析。结果表明,长江流域珍稀濒危植物60科109属154种,占全国珍稀濒危植物种类的39.7%,其中蕨类植物9科9属10种,裸子植物7科23属38种,被子植物44科77属106种;长江流域国家重点保护植物126种,其中Ⅰ级31种,Ⅱ级95种。分析了长江流域珍稀植物和国家重点保护植物的分布特点及保护现状,提出了相应的保护措施。

Based on research achievements on rare and in imminent dangerous plants as well as the plants mainly protected by government in 19 provinces(Autonomous Regions,cities directly under the Central Government)of the Yangtze basin,and in the combination of 《Red Book of Chinese Plants(volume one)》 and 《Wild Plant Directory Mainly Protected by Government(Group one)》 approved by the State Council in August,1998,the rare and in imminent dangerous plants as well as the plant resources mainly protected by government in the Yangtze basin are counted and analyzed.The statistical and analysis results demonstrate that there are the rare and in imminent dangerous plants of 154 species,60 families and 109 genus,accounting for 39.7% of the national rare and in imminent dangerous plants,in which,pteridophyte of 10 species,9 families and 9 genus,gymnosperm of 38 species,23 families and 7 genus,angiosperm of 106 species,44 families and 77 genus;the plants mainly protected by the government are 126 kinds,in which,31 kinds in classification I,95 kinds in classification II.The distribution condition and protection status quo of rare and in imminent dangerous plants as well as the plants mainly protected by government in the Yangtze basin are analyzed and correspondent protection measures are put forward.
