摘要
描述了黄河三角洲地区耐盐乡土植物的种类及生态价值。黄河三角洲地区耐盐乡土植物以草本植物为主,灌木和乔木零星分布。主要耐盐乡土植物有芦苇、盐地碱蓬、柽柳和旱柳等。黄河三角洲地区耐盐乡土植物发挥着重要的生态作用,主要包括:防风固沙,保持水土,调节气候;固碳增汇,补偿碳排放;防治重金属等污染;净化水质;维持生物多样性;改良盐渍土。
The kinds and ecological value of salt-tolerant native plants in Yellow River Delta were de- scribed in this article. The salt-tolerant native plants in Yellow River Delta majored in herbs, shrubs and trees just scattered in herbs. The primary species of salt-tolerant native plants were Phragmites australis, Suaeda salsa, Tamarix chinensis, Salix matsudana and so on. These plants played an important role on the ecology. First, they prevented wind, fixed sands, conserved water and soils, and regulated climate. Secondly, they sequestrated carbon and increased the carbon sink, so it compensated the carbon emis- sions. Thirdly, they prevented and controlled pollutions such as heavy metals. Besides, they cleaned the water quality, maintained biodiversitv and improved saline soils.
