摘要/Abstract

摘要： 在上海市选取20个公园和2个化工厂设立22个样点,对地面藓类植物进行野外样方调查、标本鉴定和数据统计.基于5种记录的藓类植物及其盖度数据,应用双向指示种分析法(TWINSPAN)和除趋势对应分析(DCA)分析其分布格局.结果表明,上海市地面藓类植物可聚类为3个样点组,样点组1为市中心2个公园和2个化工厂,共有藓类23种,总盖度最小(21.29%);样点组2为部分市中心公园和外围公园,共有藓类44种,总盖度37.94%;样点组3主要为外围公园和市郊公园,共有藓类49种,总盖度为49.66%.结果反映了藓类植物分布与不同生境,环境污染及人为干扰有一定相关性.

Abstract: The mosses on the floor of 22 sites at 20 main parks and 2 chemical plants in Shanghai city were investigated and sampled.Based on 75 recorded moss species and their coverage,Two-way Indicator Species Analysis (TWINSPAN) and Detrended Correspondence Analysis (DCA) were used to analyze their distribution patterns.The results showed that the study sites could be identified as three groups.Group 1 included two chemical plants and two parks at the center of the city,with 23 moss species and the smallest total coverage of 21.29%;group 2 included part of the parks at the center of the city and surrounding areas,with 44 moss species and total coverage of 37.94%;and group 3 mainly included the parks at surrounding areas and suburbs of the city,with 49 moss species and total coverage of 49.66%.The results reflected a certain correlation of the distribution of moss species with different habitats and polluted and disturbed environments in the city.
