珍稀濒危植物评价分级专家系统研究

The evaluation and gradation expert system for rare and en-dangered plants

开列珍稀濒危植物的清单并划分其保护序列，是生物多样性保护的一项最基本的工作。本文通过对珍稀濒危植物评价分级指标的研究，以评价指标体系为基础，并引入专家系统方法，建立了珍稀濒危植物评价分级专家系统。该系统模拟人类专家的思维过程，将有助于把珍稀濒危植物优先保护级别的划分，由定性划分提高到定量定性相结合的水平。

The listing of stressed plants checklist and di-vision of conservation sequence is one of the most important issues in plant diversity conservation .In this paper,the evalua-tion and gradation indexes for rare and endangered plants were studied,the method of expert system was introduced and an expert system for evaluating and grading rare and endangeredplants was established.The established expert system can,to acertain extent,simulate human experts' thinking process .It will be helpful to turn the qualitative division into a combina-tion of qualilative and quantitative division for prior conserva-tion class of stressed plants.so as to make more objective andaccurate evaluation of the extent of stressed plant species andreasonable determination of the conservation level of plant species.
