| 摘要: |
| 在地处广东省沿海的汕头市市区设置固定风口调查小区，分别在 2003 年第 13 号台风“ 杜
鹃”、 2005 年第 10 号强热带风暴“ 珊瑚”、 2006 年第 1 号强台风“ 珍珠” 过后进行绿化树种风害调查 ; 以
灾后风害木恢复原景观的修复投入比例综合专家咨询确定权重，采用改良加权评分法分析城市绿化树种
的抗风性，结果表明：汕头市区 66 个常见绿化树种，可以划分为 4 个抗风级别，其中Ⅰ级树种 36 个，
抗风性较强； Ⅱ级树种 19 个，抗风性一般； Ⅲ级树种 7 个，抗风性较差； Ⅳ级树种 4 个，不抗风。 |

| Abstract: |
| Through setting up a fixed tuyere investigation area in the coastal area of Guangdong province,
Shantou city, the wind damage on greening tree species were investigated after three wind damage, which were
the thirteenth typhoon“ cuckoo” in 2003, the tenth tropical storm“ coral” in 2005, and the first strong typhoon
“ pearl” in 2006. In order to analyze the wind resistance of greening tree species, this paper took the repair investment ratio and expert consultation as weight coefficient by modified weighted mark method. The result showed
that there were sixty-six common greening tree species in Shantou city, which could be divided into four wind-resistant levels. The 36 species of the first class have superior wind-resistance, the 19 species of second class have
the general wind-resistance, the wind-resistance of 7 species in third class is low, and the 4 species in fourth class
do not have the wind-resistance. |
| Key words: greening tree species wind damage type repair investment wind-resistant level |
