摘要
通过野外调查和大量文献资料的整理和分析,确定杭州有外来杂草75种,隶属于30科55属。通过对杭州外来杂草的种类组成、原产地、入侵途径和生境特点进行分析,结果表明:杭州的外来杂草主要为菊科、苋科、大戟科、豆科和旋花科,占总数55%;来源于美洲的外来杂草对杭州容易入侵并造成较大危害;荒地等地表裸露较大的生境外来杂草容易入侵定居。并对如何加强管理和控制外来物种提出几点建议。
75 exotic weed species belonging to 55 genera, 30 families are identified and recorded in Hangzhou through investigation and related literatures. The composition, origin area, invasive routes and habitat characteristics are discussed in this paper. The results show that： Compesitae, Amaranthaceae, Euphorbiaceae, Leguminosae and Convolulaceae are the five main families, comprising about 55 percent of the exotic weeds in Hangzhou; Exotic weeds originating from America are easier to invade and take more harm to Hangzhou; Uncovered habitats such as wasteland trend to be invaded and settled more easily than others. And some effective management strategies are proposed.
