50种山茶科植物的综合评价

Comprehensive Evaluation of Fifty Camellia Species

应用层次分析法,选择观赏特性、生态习性、利用价值作评价因素,对山茶科50个原生种进行了综合评价。结果表明:观赏特性为最重要评价因素,生态习性居次,最后是利用价值;观赏特性的指标层按权重值大小排列依次是形、花、叶、果、枝。50种山茶科植物分为3个等级,Ⅰ级有14种,形态特征明显,观赏价值高,被开发利用程度也最高;Ⅱ级有20种,观赏性还未受到关注,开发利用潜力很大;Ⅲ级16种,观赏性偏低,未见应用,但有些种科研价值很高。

Applying AHP method,50 species of Camellia were comprehensively evaluated through ornamental characteristics ,ecological characteristics & utilization value.Result shows that ornamental characteristics are the most important evaluation factors,ecological subordination,and finally the utilization value;the descending order of index layer for ornamental characteristics by the weights is shape,flowers,leaves,fruits,branches.Fifty species of Camellia were classified into three levels.There are fourteen species in LevelⅠ,with evident morphological charac-teristics,high ornamental value and the highest utilization extent;while there are twenty species in LevelⅡ,with ornamental value still unconcerned and large developed potential;there are sixteen species in Level Ⅲ,which are of low ornamental value and unapplied.But some of them are of high research value.
