摘要:

基于深圳市仙湖植物园收集保存的蕨类植物资源,运用层次分析法构建评价体系,对42种具有园林应用潜力的蕨类植物进行观赏价值综合评价。结果表明,在一级指标中,叶片所占权重最大,为46.73%,其余依次为生境情况(27.72%)、根状茎(16.01%)以及孢子囊群(9.54%)。在二级指标中,叶色、长势、叶整体形态和茎走向占蕨类植物观赏价值的总权重均超过10.00%,对评价结果有较大影响。其中叶色的总权重达到19.98%,是影响蕨类植物观赏价值的关键指标。根据指标权重和评分标准,对42种蕨类植物进行综合评分并划分为4个等级:Ⅰ级(总分>4.0)为观赏价值高的种类,共计7种;Ⅱ级(3.5<总分≤4.0)为观赏价值较高的种类,共计11种;Ⅲ级(3.0<总分≤3.5)为观赏价值一般的种类,共计15种;Ⅳ级(总分≤3.0)为观赏价值低的种类,共计9种。聚类分析结果表明,疣茎乌毛蕨、肾蕨、笔筒树、苏铁蕨、平鳞黑桫椤、长叶肾蕨、大叶黑桫椤等7种Ⅰ级蕨类植物均长势优良,且在叶片和根状茎的观赏性状上表现突出,具有较好的园林应用前景,可大规模开发利用。

Abstract:

Based on the fern resources collected and preserved in Shenzhen Fairy Lake Botanical Garden,the evaluation system was constructed using the analytic hierarchy process to comprehensively evaluate the ornamental value of 42 species of fern with potential for garden application. The results showed that among the primary indicators,leaves accounted for the largest weight,which was 46.73%,followed by habitat conditions(27.72%),rhizomes(16.01%),and spore sac group(9.54%). Among the secondary indicators,leaf color,vigor,overall leaf morphology,and stem direction accounted for more than 10.00% of the total weight of the ornamental value of fern,which had a great influence on the evaluation results. Among them,the total weight of leaf color reached 19.98%,which was the key indicator affecting the ornamental value of fern. According to the indicator weights and scoring criteria,the 42 species of fern were comprehensively scored and divided into four levels:Level I(score>4.0)was for species with high ornamental value,totaling 7 species;Level Ⅱ(3.5<score≤4.0)was for species with relatively high ornamental value,totaling 11 species;Level Ⅲ(3.0<score≤3.5)was for species with average ornamental value,totaling 15 species;Level Ⅳ(score≤3.0)was for species with low ornamental value,totaling 9 species. In addition,the results of cluster analysis showed that seven Class I fern species,including Blechnum gibbumNephrolepis cordifoliaSphaeropteris lepiferaBrainea insignisGymnosphaera henryiNephrolepis biserrata,and Alsophila gigantea,all grew well and performed outstandingly in the ornamental traits of their leaves and rhizomes,which had good prospects for garden application and could be developed and utilized on a large scale.
