广西紫金牛属野生观赏植物的综合评价

利用层次分析法,综合观赏价值、资源开发潜力、生物学特性三大约束因素共14个指标,对分布于广西的29种紫金牛属野生观赏植物进行综合评价。结果表明:按照开发利用价值的高低,可将29个种(变种)根据轻重缓急划分为4个等级,其中:Ⅰ级:开发利用价值高的种类,5个;Ⅱ级:开发利用价值较高的种类,9个;Ⅲ级:开发利用价值一般的种类,9个;Ⅳ级:开发利用价值较低的种类,6个。研究结果将为科学、合理地开发利用广西紫金牛属野生观赏植物资源提供决策依据。

Comprehensive evaluation of the wild ornamental plants of Ardisia in Guangxi

The analytical hierarchy process(AHP) was used to evaluate the wild ornamental plants of Ardisia which mainly distributed in Guangxi,and three major constraint factors with 14 indicators:ornamental value,resource development potential and biological characteristics.According to the discretion of the exploitation and utilization value,29 species of Ardisia were classified into four grades,including Level Ⅰ,the exploitation value of 5 species was the highest;Level Ⅱ,the exploitation value of 9 species was higher;Level Ⅲ,the exploitation value of 9 species was general;Level Ⅳ,the exploitation value of 6 species was lower.The results would provide the basis for decision-making the development and utilization of the wild ornamental plants of Ardisia.
