摘要: 在确定中国东北地区受威胁植物的基础上,依据植物优先保护值确定受威胁植物的优先保护区域.结果表明: 中国东北地区共有受威胁植物25科42属60种.在东北地区219个县(市)中,共119个县(市)分布有受威胁植物.吉林省安图县是东北地区拥有受威胁植物最多的县,有受威胁植物42种.确定吉林省安图县、辽宁省桓仁满族自治县等16县(市)为东北地区受威胁植物优先保护县(市).根据受威胁植物的优先保护区域值,划分出中国东北地区的5个优先保护区域,分别为长白山优先保护区、辽东优先保护区、辽南优先保护区、张广才岭优先保护区和小兴安岭优先保护区,并对各优先保护区的主要受威胁植物进行了分析.

Abstract: Based on the identification of the threatened plants in Northeast China and the priority conservation value of plants, the priority conservation regions of the threatened plants in Northeast China were determined. In the study area, there were 60 species of threatened plants, belonging to 42 genera and 25 families. In the 219 counties (or cities) of Northeast China, 119 counties (or cities) had the distribution of threatened plants. The Antu County in Jilin Province had the most species (42) of threatened plants. A total of 16 counties (cities) such as the Antu County of Jilin Province and the Huanren Manchu Autonomous County of Liaoning Province, etc. were identified as the priority conservation regions of the threatened plants in Northeast China. According to the priority conservation value, five priority conservation regions of threatened plants in Northeast China were divided, including Changbai Mountain conservation region, East Liaoning conservation region, South Liaoning conservation region, Zhangguangcai Mountain conservation region, and Xiaoxing’an Mountain conservation region. The main threatened plants in each priority conservation region were also analyzed.
