- 摘要:
- 以海口市公园常见的18种棕榈植物为试材,采用分区调查法,研究了棕榈风害受损情况并测定形态学相关指标,利用层次分析法(AHP)对所测指标进行量化处理,再用综合评价法对受损指标、模糊隶属函数法对形态指标分别进行综合评分,根据综合评分进行聚类对比分析,以探索棕榈植物抗风性强弱及其与受损指标之间的关系,建立抗风性强弱的形态指标预测体系。结果表明:受损指标中主干断裂、主干倒伏、枝梢断裂及形态指标中的树木类型、树高、胸径、冠幅与棕榈植物抗风性强弱关系密切,权重值分别为0.444 6、0.287 6、0.124 3、0.415 5、0.148 6、0.236 8、0.126 1,分别高于其它所测指标;受损指标与形态指标聚类分析结果基本一致,18 种棕榈植物抗风性强弱均可分为3级,分级完全相符的有14种,其中Ⅰ级6种,Ⅱ级4种,Ⅲ级4种,其余4种分级结果相近。滨海公园棕榈植物的抗风性强弱差异较大,模糊隶属函数法可作为棕榈植物抗风性评价方法,主干断裂、主干倒伏及枝梢断裂可作为判断其抗风性强弱的主要指标,可通过树木类型、树高、胸径、冠幅来预测棕榈植物的抗风性强弱。
- Abstract:
- Taking the common 18 species of palm plants in the gardens of Haikou city as materials,using partition survey method,the wind damage and morphologic indexes was surveyed,using the analytic hierarchy process for the indexes measured to make quantitative processing and then comprehensive evaluation was used on the damaged indexes,fuzzy subordination method was composite score of the morphological indexes,based on comparative analysis of cluster combined score between palm plants to explore the wind resistance and damaged indexes relations,to establish aprediction system of the wind resistance of the morphological indexes.The results showed that the trunk breakage,trunk lodging,shoot breakage in damaged and morphological indexes of trees type,height,diameter,crown were close to the wind resistance of the palms plants,weight factors were respectively 0.444 6,0.287 6,0.124 3,0.415 5,0.148 6,0.236 8,0.126 1,which higher than the other measured indexes.Damaged indexes consistent with the morphological indexes in clustering analysis,18 species of palm plants wind resistance strength both could be divided into three grades,entirely consistent with the classification of 14 species,of which grade I were 6 species,grade Ⅱ were 4 species,grade Ⅲwere 4 species,another 4 species were similar.Coastal park palm plants had different wind resistance strength,the method of fuzzy function could be used as wind resistance evaluation method of the palm plants,the trunk breakage,trunk lodging,shoot breakage could be used as the main indexes of its wind resistance,the trees type,height,diameter,crown to predict the strength of the wind resistance of the palms plants.
