摘要
本研究以1993—2005年对调查的85科、199属、270种、25变种、3变型长白山区珍稀濒危保护植物为对象,通过对其评价指标的定量化和权重分配处理,求得物种的“濒危系数”和“优先保护值”,确定出了物种濒危程度和优先保护序列。为国内外专家研究长白山区珍稀濒危植物及有关部门制定具体的保护措施提供了第一手原始资料。
This paper dealed with 85 families, 199 genuera, 270 species, 25 varieties and 3 formes of rare and endangered plants investigated in Changbai Mountains from 1993 to 2005. The＂ coefficient of endangerment＂ and the ＂value of superior conservation＂were obtained through index quantification and weight allocation, thus the degree of endangerment and the sequences of protection priority were determined. They could offer a first-hand primitive materials for the domestic and foreign experts who studied the rare and endangered plants in Chanbai Mountains and for some relevant departments who formulated the concrete protection measures.
