摘要:
1997年5~9月低洼盐碱地鱼虾混养塘中的浮游生物数量与生物量的月变化特点为:浮游植物中隐藻、裸藻与硅藻生物量在实验期间较高,蓝藻与绿藻在数量上占优势,进入秋季后蓝藻数量逐渐超过绿藻;浮游动物中原生动物、桡足类数量分别在5、6月份占优势,桡足类生物量这两个月占绝对优势,轮虫、原生动物的数量分别在7、8月份优势明显.结果表明实验期间小型浮游生物数量增加.分析表明,低洼盐碱地池塘水体浮游生物的变化与水体营养盐的含量、水产经济动物(鱼虾)、水温等因素密切相关.

Abstract:
This paper studied the plankton community of fish and shrimp culture ponds in saline-alkaline wetlands during May to vSeptember 1997.In terms of numbers, the species of Chloro-phyta dominated the community of phytoplankton in May, June and August, and Cyanophyta were the main taxa in July and September.However, Cryptophyta, Euglenophyta and Ba-cillariophyta were the most important components of the phytoplankton community in terms of biomass.According to the analysis of biomass, Copepoda was predominant in May and June, and Rotifera and Protozoa dominated the zooplankton community in July and August, respectively.Our results also suggests that the changes in the plankton communities of the ponds in saline-alkaline wetlands are due to a number of factors including nutrient concentration, abundance of fish and shrimp and water temperature.
Key words:  plankton  culturing pond  saline-alkali wetland
