摘要

以洱海流域典型湿地——罗时江湿地为例,调查分析湿地内主要湿地植物物种,测定主要湿地植物秋季地上可收割部分生物量、植株含水率及氮磷含量,计算单位面积湿地植物氮、磷同化量。再依据各种湿地植物面积,初步估算开展秋季湿地植物收割可移除的氮、磷数量。
        Taking Luoshijiang wetland,a typical swamp of Erhai Lake basin,as an example,the major wetland plant species were investigated and analyzed. The dominate wetland plants' biomass of harvest parts,water content,nitrogen content and phosphorus content in autumn were measured. The assimilation amounts of nitrogen and phosphorus of wetland plants per unit area were calculated based on these parameters. Finally,the overall quantities of removable nitrogen and phosphorus by conducting the autumn wetland plants harvest were preliminary estimated.
