摘　　要：采用TWISPAN分析方法,对北京市延庆采矿迹地湿地40个样地51种植物进行了分类排序,将群落类型划分为7个类型,即茵陈蒿-狗尾草-黄花蒿群落、野艾蒿-茵陈蒿-尖叶胡枝子-狗尾草群落、野艾蒿-茵陈蒿-狗尾草-野大豆-苣荬菜群落、狗尾草-苍耳-黄香草木犀-虎尾草群落、狼拔草-野艾蒿-旋覆花-大籽蒿-芦苇群落、香蒲-芦苇-茭白-野大豆-鬼针草群落和竹节灯心草-褐穗莎草-稗群落;同时运用双变量主坐标分析(DPCoA)对51种植物进行了排序分析,研究结果显示研究区存在两种演替规律,即由喜湿旱生耐淹水植物演替为喜旱旱生植物和由湿地挺水植物向湿生植物演替两种类型。对于采砂基地型湿地植被恢复不仅恢复土壤营养条件,调控湿地水分条件也是十分关键的。研究结论将为采砂迹地型湿地恢复提供科学支持。In this paper, we analyzed and ordered the 51 plant species in 40 sampling locations in trail wetlands in Yanqing County,Beijing City by using TWISPAN analysis, and divided the vegetation communities into seven types, which were type Artemisia capillaris-Setaria viridis-Artemisia annua, type Artemisia lavandulaefolia-Artemisia capillaris-Lespedeza caraganae-Setaria viridis, type Artemisia lavandulaefolia-Artemisia eapillaris-Setaria viridis-Glycine soja-Sonchus arvensis, type Setaria viridis-Xanthium sibiricum-Melilotus officinalis-Chloris virgate, type Bidens tripartita-Artemisia lavandulaefoIia-lnula japoniea-Artemisia sieversiana-Phragmites australis, type Typha orientalis-Phragmites australis-Zizania latifolia-Glycine soja-Bidens bipinnata, and type Juncus effusus-Cyperus fuscus-Echinoehloa crusgalli. We also sorted and analyzed the 51 plant species by double variables principal coordinates analysis （DPCoA）. The results showed that there were two succession rules for plant communities in this area, which were the succession from typical stand wetland plant species to ordinary wetland plant species, and the succession from hygrophilous plants to terraneous plants. The vegetation restoration in sand-mining wetland should not only restore soil nutrient, but also regulate water condition. The findings can provide a scientific support for mining trail wetlands restoration.
