【摘要】 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。更多还原

【Abstract】 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 characteristics,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 LevelⅢ,which are of low ornamental value and unapplied.But some of them are of high research value.更多还原
