摘要:

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。

Abstract:

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.
