摘要
2016年初在"拉尼娜"现象的影响下,福州市园林植物遭受严重冻害.本研究以福州市43个公园的绿地植物及其受冻害情况的调查为基础,分析其受冻植物组成、生活型和来源地特征.结果表明:1)常见绿地植物901种(隶属148科547属),共有受冻害植物272种(隶属97科197属,占总量的30.19％);其中,受冻的本地植物68种,占本地植物总量的13.44％,受冻的外来植物204种,占外来植物总量的51.65％.2)在生活型上,草本受冻害物种最多,其次为灌木、乔木,藤本植物最低,多年生草本＞一年生草本,常绿木本＞落叶木本.3)在受冻外来植物的引种地上,国内的广东、云南、海南和国外的美洲热带、南美洲、亚洲热带、北美洲、大洋洲等8个地区的受冻植物占相应地区引种总量的半数以上,引种受冻风险高.
Abstract
Under the inpact of＂La Ni?a＂ in early 2016,the gardening plants had suffered seriously frozen injury in Fuzhou.Based on the investigation of 43 parks in Fuzhou,the species composition,life form and origin areas of the frozen plants were analyzed in this study.The results showed that 1)there are 901 species of common green plants in 547 genera and 148 families,including 272 species of frozen plants(accounting for 30.19％)in 197 genera and 97 families.Among the frozen plants,there are 68 native species accounting for 13.44％of the total number of native species,and 204 non-orginal species accounting for 51.65％of the total number of non-orginal species.2)In the life forms,the degrees of freezing injury are herb ＞shrub ＞tree ＞vine,evergreen woody ＞deciduous woody,and perennial herbs ＞annual herb.3)For the domestic and abroad areas the plants introduced from,the proportions of frozen plants introduced from the Guangdong,Yunnan and Hainan Province,and tropical Asia,South America,North America and Oceania abroad accounted for more than half of the introduced plants numbers in the corresponding area separately,implying high freezing injury risk for introduction from these areas.
