珍稀植物优先保护分级指标的研究

Study on superior conservation grading index of the rare plants

通过对珍稀植物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” ,从而确定物种的濒危程度和优先保护的序列 ,研究结果表明 ,该定量分级比当前国内外普遍采用的定性分级更能真实和全面地反映植物的濒危状态和优先保护的程度 ,该方法适应各类植物优先保护的比较评定。

The coefficient of endangerment and the value of superior conservation of the rare plants were computed through fixing quantity and balancing arrangement treatation with evaluating index, thus the degree of endangerment and the alignment of superior conservation were determined; the study conclusion shows that this fixing quantity method is and more reliable comprehensive than fixing quality method in reflecting endangerment situation and degree of superior conservation and is fit to comparative judgment all class plant's superior conservation.
