浙江省平原河道植物调查和应用

为了研究植物措施在平原河道生态治理的中重要作用,通过对浙江省13个县市的平原河道植物进行全面调查,结果表明:浙江省平原河道有河道维管束植物751种(包括种下分类等级),隶属97科.其中蕨类植物11科15种,裸子植物2科5种,被子植物84科731种.按植物的生态学特性分类,中生植物459种,湿生植物169种,水生植物123种.在水生植物中,挺水植物68种,沉水植物25种,浮叶根生植物19种,漂浮植物11种.根据河道植物的适应性、群落亲和度、功能性和景观性的原则,筛选出71种作为浙江省平原河道生态整治的推荐植物.结合浙江省平原河道的特点,讨论了植物措施在平原生态河道整治中的展望.

Investigation and utilization of plain river plants in Zhejiang Province

To study the function of plants in ameliorating river environment, the plain river plants investigated from 13 counties in Zhejiang Province. The investigation shows that there are 751 species of vascular plants of river in Zhejiang Province, bordinate to 97 families, including 11 families 15 species fern,2 families 5 species gymnosperm ,84 families 731 species angiosperm. Based on the ecological characteristic the plants could be classified into 459 species of common plants, 169 species of hygrophyte, 123 species of aquatic plants. The aquatic plants could be classified emergent plants 68 species, submerged plants 25 species, floating-leaved plants 19 species, floating plant 11 species. According to principles of plant adaptability, communication appetency, functionality and landscape, 71 species with high value of utilization river plants are recommended. The paper suggests the ways to utilize plants to ameliorate river environment.
