| 摘 要： | 对甘肃省张掖市黑河流域中游典型退化湿地植被特征进行了研究,分析了影响湿地植被退化的主要原因,探讨了研究区退化湿地的植被恢复技术。研究结果表明,研究区分布有植物45科123属196种,其中,禾本科(Poaceae)、菊科(Asteraceae)、藜科(Chenopodiaceae)和豆科(Leguminosae)包含的植物属较多,分别占研究区植物属总数的17.07%、9.76%、7.32%和7.23%。湿地植物群落的种类组成主要以广布性的湿生、盐生和中生植物为优势种,植物群落以盐生、湿生和沼泽型的植物群落为主。提出了采用天然湿地补水、湿地封育、人工种草和栽植湿地植物恢复技术,以及实施生态农业与"退耕还湿"等工程,进行湿地植被恢复。

| Abstract: | The vegetation characteristics of typical degradation wetlands in the middle reaches of Heihe River basin in Zhangye city,Gansu province were studied in this study.The main influence factors of vegetation degradation were analyzed and the restoration technology of the degradation vegetation was discussed in the paper.The results indicated that there were 45 families,123 genera and 196 species of the plants distributed in the study area.The main types of plant species composition in the degradation wetlands were humidogene,halophytes and mesophyte,and the main types of plant communities included Com.Acorus calamus,Com.Halerpestes sarmentosa,Com.Phragmites australis,Com.Rhizoma Scirpi Yagarae,Com.Tamarix chinensis,and Com.Potamogeton pusillus—Myriophyllum verticillatum.The technology of ecological water supplement,enclosure of the degradation wetlands,planting grasses artificially and cultivated plants of the wetlands was put forward to;and the projects of the ecological agriculture and ’to return farmlands to wetlands’ were carried out for the restoration of degradation wetlands. |
