南天竹开发利用价值评价体系的建立

以湖南南天竹13个地方种源为研究对象,开发利用价值为目标,并基于观赏植物的观赏特证,确定了22个评价指标,建立了观赏植物南天竹种质资源开发利用价值层次分析(Analytic Hierarchy Process,简称AHP)评价模型.结果表明:岳阳、祁阳、衡山、柏加、黄花机场等地的南天竹的观赏价值、资源潜力、生物学特性等在园林应用中得分值最高,即开发利用价值高,而张家界、邵东南天竹在园林应用中开发利用价值较低;可根据开发利用途径和目的进行其它方面的开发利用,如盆景和水土保持方面.以AHP模型评价湖南南天竹,旨在为今后开发利用湖南南天竹资源提供理论依据.

Establishment of Value Evaluation System for Exploitation and Utilization of Nandina domestica in Hunan

In order to excavate the exploitation and utilization value of Nandina domestica in Hunan,22 appraisal indexes were determined,and based on the characteristics of Nandina domestica resources,an evaluation model was established by means of Analytic Hierarchy Process(AHP).Using this appraisal system,the whole Nandina domestica resources were evaluated.Results show that the exploitation and utilization of such Nandina domestica resources is of the highest value as in Baijia,Yueyang,Huanghua Airport,Qiyang and Hengshan,but the exploitation and utilization of such Nandina domestica resources is of the lowest value as in Zhangjiajie and Shaodong concerning their application to gardening.The exploitation and utilization of the latter can be done in other aspects according to their different purposes.These appraisal results with AHP will provide a theoretical foundation for further exploitation and utilization of Nandina domestica resources in Hunan.
