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.
