| 摘 要： | 在重庆市江北区铁山坪森林公园对13个主要树种进行了调查,选择有代表性的10个样地,主要从树木的死亡率、落叶率并结合树叶的变色率和变形对树种抗旱性进行综合分析评价,得到结论:抗旱性强的树种为木荷;较强的树种依次为枫香、峨嵋紫楠(Phoebe sheareeni vomeiensis);中等的树种依次为石栎、野杏树(Prunus)、毛桐(Mallotus barbatus)、漆树、青皮(Schoepfia jasminodora)、香樟、杉木、马尾松;差的树种依次为槲栎(Quercus fabri hance)、毛叶木姜子(Litsea mollis)。 |

| Abstract: | Drought resistance is an important indicator of adaptation of treespecies￡··it is of vital significance for op-erations of forestation and forestmanagement. In 2006,a severe droughthappened in Chongqing,this enables usto clearly see the difference of drought re-sistance among main tree species undernatural conditions. The drought resistancewas investigated for 13 main tree speciesat the Forest Park of Tieshanping,Chongqing,by comparing several indica-tors among the individual trees in 10stands. The indicators are mortality,defoliation,discoloration and leafdeformation. Mainly based on the com-parison of mortality and defoliation,thedrought resistance of the 13 investigatedtree species are ranked as following:1)high drought-resistance: Sapiumsebiferum; 2) relatively high drought-resistance: Liquidambar formosana,Phoebe sheareeni var. omeiensis; 3) mod-erate drought-resistance: Lithocarpusglaber,Prunus,Mallotus barbatus,Toxi-codendron verniciflua,Schoepfiajasminodora,Cinnamomum camphora,Cuninhamia lanceolata,Pinusmassoniana; 4) low drought-resistance:Quercus aliena,Litsea mollis. |
