摘要：利用TWINSPAN(双向指示种分析)和CCA排序(典范对应分析)的方法,对北京西卓家营采砂迹地型退化湿地植被进行了群落类型划分,并探讨了湿地植被空间分布与土壤环境因子关系,确定了影响湿地植被空间分布的关键因子。结果表明:38个样方40个植物种可划分为7个群落类型,即茭白+针蔺群落(Zizania latifolia+Eleocharis congesta);牛鞭草+旋覆花+野艾蒿+竹节灯心草+茵陈蒿+扁杆藨草群落(Hemarthria sibirica+Inula japonica+Artemisia lavandulifolia+Juncus turczaninowii+Artemisia capillaries+Scirpus planiculmis);千屈菜+苣荬菜+小香蒲群落(Lythrum salicaria+Herba Sonchi Brachyoti+Typha minima);竹节灯心草+问荆+酸模叶蓼+芦苇群落(Juncus turczaninowii+Equisetum arvense+Polygonum lapathifolium+Phragmites australis);针蔺+扁杆藨草+茵陈蒿+野艾蒿群落(Eleocharis congesta+Scirpus planiculmis+Artemisia capillaries+Artemisia lavandulifolia);鬼针草+狗尾草+香蒲群落(Bidens pilosa+Setaria viridis+Typha orientalis)和朝天委陵菜+猪毛菜+大刺儿菜+稗群落(Potentilla supine+Salsola collina+Cephalanoplos setosum+Echinochloa crusgalli)。植物群落物种和土壤因子的CCA分析表明:益母草、大车前、猪毛菜主要受土壤pH的影响;茭白主要受氨氮、土壤有机质(SOM)的影响;马唐、鸡眼草主要受土壤全氮(TN)和Mg2+的影响;针蔺、狼杷草受土壤K+的影响;苦苣菜、苣荬菜、牛鞭草主要受土壤Na+的影响;黄香草木犀主要受土壤Cl-的影响;灰绿藜、大刺儿菜、球穗莎草主要受土壤NO3-的影响;扁杆藨草、小香蒲主要受全磷(TP)和含水率的影响。研究结论将为采砂迹地型湿地恢复提供科学支持。
The structures and types of plant communities of sand-mining land deteriorating wetland in Xi zhuojiaying were analyzed by the methods of TWINSPAN and CCA ordination.The distribution pattern and its impact factors were discussed.The results showed that 40 species of 38 samples were divided into seven formations which can be described as follows： Zizania latifolia＋Eleocharis congesta,Hemarthria sibirica＋Inula japonica＋Artemisia lavandulifolia＋Juncus turczaninowi＋Artemisia capillaries＋Scirpus planiculmis,Lythrum salicaria＋Herba Sonchi Brachyoti＋Typha minima,Juncus turczaninowii＋Equisetum arvense＋Polygonum lapathifolium＋Phragmites australis,Eleocharis congesta ＋Scirpus planiculmis Fr.Schmidt＋Artemisia capillaries＋Artemisia lavandulifolia,Bidens pilosa＋Setaria viridis＋Typha orientalis and Potentilla supine＋Salsola collina＋Cephalanoplos setosum＋Echinochloa crusgalli.Plant species and soil factors in CCA analysis showed that Leonurus japonicus,Plantago major and Salsola collina were mainly affected by pH,Zizania latifolia mainly was affected by NH4-N and soil organic matter（SOM）,Digitaria sanguinalis and Kummerowia striata were mainly affected by TN and Mg2＋,Eleocharis congesta and Bidens tripartita were mainly affected by K＋,Sonchus oleraceus,Herba Sonchi Brachyoti and Hemarthria sibirica were mainly affected by Na＋,Melilotus officinalis was mainly affected by Cl-,Chenopodium glaucum,Cephalanoplos setosum and Cyperus globosus were mainly affected by NO3-,Scirpus planiculmis and Typha minima were mainly affected by TP and soil moisture.The results of this study would provide scientific support for sand-mining wetlands restoration.
