A comprehensive evaluation system for anti-typhoon performance of trees in coastal areas
-
摘要: 为了对沿海地区抗台风树种进行合理选择与科学评价，选取对林木抗台风性能有重要影响的生长形态、根系与材性等3大类因素16个指标，利用层次分析法构建沿海抗台风树种评价指标体系，对沿海地区10个主要造林树种（或无性系）进行优选评价。结果表明：木材材性因子是影响树种抗台风性能的关键因素，权重为0.633 3；生长形态因子次之；根系因子对树种抗台风性能影响最小，权重为0.106 2。木材材性因子中纤维长宽比与木材密度对树种抗台风性能影响最大，生长形态因子中地上部与地下部鲜质量比对林木抗台风性贡献率最大，根系因子中根深所占权重最大，所构建的抗台风树种评价指标体系为生产实践中抗台风树种的选择利用与评价提供重要参考。10个树种（或无性系）优选评价排序为木麻黄Casuarina equisetifolia无性系W8＞K18＞P6＞G1＞A8＞琼崖海棠Calophyllum inophyllum＞苦楝Melia azedarach＞巨尾桉Eucalyptus grandisE. urophylla＞马占相思Acacia mangium＞厚荚相思A. crassicarpa。该评价结果与台风过后田间风害调查结果基本一致。表7参25Abstract: To effectively evaluate and select trees in coastal areas for protection against typhoons, 16 traits from three categories including 1） growth and properties of 2） roots and of 3） wood types were chosen to establish a comprehensive evaluation system using the analytic hierarchy process （AHP）. Then 10 trees （Casuarina equisetifolia W8, Casuarina equisetifolia K18, Casuarina equisetifolia P6, Casuarina equisetifolia G1, Casuarina equisetifolia A8, Calophyllum inophyllum, Melia azedarach, Eucalyptus grandis Eucalyptus urophylla, Acacia mangium, and Acacia crassicarpa） were selected and evaluated using the comprehensive evaluation system. Results of tree performance in resisting typhoons showed that wood property was the key factor with a weight of 0.633 3, growth was second, and root traits had a minimal influence （weight of 0.106 2）. Wood property traits of 1） wood density and 2） ratio of fiber length to width had the greatest influence on anti-typhoon performance. For growth traits, the ratio of aboveground to belowground fresh weight had the largest contribution, and for root traits, root depth had the largest weight. The comprehensive evaluation system ranked the 10 trees as: Casuarina equisetifolia W8 ＞ Casuarina equisetifolia K18 ＞ Casuarina equisetifolia P6 ＞ Casuarina equisetifolia G1 ＞ Casuarina equisetifolia A8 ＞ Calophyllum inophyllum ＞ Melia azedarach ＞ Eucalyptus grandis Eucalyptus urophylla ＞ Acacia mangium ＞ Acacia crassicarpa. Evaluation results were consistent with typhoon damage investigations, so this comprehensive evaluation system could provide an important reference when selecting and evaluating trees for anti-typhoon performance. ［Ch, 7 tab. 25 ref.］
