以江西省受威胁的32种药用植物为研究对象，制定出江西省珍稀濒危药用植物保护的定量化分级标准。经过一系列评价标准的定量化及权重分配处理，以求得药用植物种的“濒危系数”和“急切保护值”，然后确定药用植物的受威胁程度和急切保护的序列。通过对32种药用植物的综合评价表明，本定量分级比目前国内外采用的定性分级，能更客观地反映出药用植物的受威胁状态和需要急切保护的程度。
Taking the 32 kinds of medicinal plants that are threatened in Jiangxi Province as the research object, the quantitative classification standards for the protection of rare and endangered medicinal plants in Jiangxi Province were formulated. After a series of evaluation criteria quantification and weight distribution processing, in order to obtain the “endangered factor” and “emergency protection value” of medicinal plant species, and then determine the threatened degree of medicinal plants and the sequence of eager protection. Through the comprehensive evaluation of 32 medicinal plants, it is shown that this quantitative classification can more objectively reflect the threatened status of the medicinal plants and the degree of urgent protection needed than the current domestic and foreign adoption of qualitative classification.
