Abstract
用五种不同的方法估算了滆湖水生植物的生物量,比较分析了全湖断面生物量和群丛生物量.分三个方面对滆湖水生植物的演替规律进行了讨论,对草型湖泊水生植物的合理利用进行了探讨.初步提出了草型湖泊估算渔产潜力的公式.在分析引起水生植物生物量变化的原因的基础上,提出了若干合理利用植物资源的建议.;The present study was carried out from 1986 to 1990. Five different methods were chosen to calculate the biomass of aquatic plants in Gehu Lake. The transect association in whole lake is compared and analysed. The changing pattern of aquatic plants in the lake is discussed in three aspects, also a discussion about their rational utilization is given. An equation for estimating potential fishery production in a densely macrophyte-covered lake is preliminarily proposed. in the last part of the paper, the reasons for the biomass variation of aquatic plants in Gehu Lake are discussed, some suggestions are preliminarily made of the rational utilization of aquatic plants in Gehu Lake.
