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 capillaris-Setaria viridis-Glycine soja-Sonchus arvensis,type Setaria viridis-Xanthium sibiricum-Melilotus officinalis-Chloris virgate,type Bidens tripartita-Artemisia lavandulaefolia-Inula japonica-Artemisia sieversiana-Phragmites australis,type Typha orientalis-Phragmites australis-Zizania latifolia-Glycine soja-Bidens bipinnata,and type Juncus effusus-Cyperus fuscus-Echinochloa 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.
