摘要
初级生产力是水生生态系统结构与功能的基础环节,是评价水体富营养化水平的重要指标,对研究水生生态系统及其环境特征具有重要意义,同时对湖泊生态系统和湖泊环境特征具有较强的指示作用。本文通过对巢湖湖区20个监测点位的初级生产力进行为期2年的调查研究,分析巢湖湖区初级生产力的分布情况,得出西半湖日产量、净生产量、呼吸作用量和P/R系数均高于东半湖,由此可知,西半湖的生物量高于东半湖。
Primary productivity is the basic link of the structure and function of aquatic ecosystem.It is an important index to evaluate the level of water eutrophication.It is of great significance to the study of aquatic ecosystem and its environmental characteristics.At the same time,it has a strong indicating effect on lake ecosystem and lake environmental characteristics.In this paper,the primary productivity of 20 monitoring points in Chaohu Lake area is investigated for two years,and the distribution of primary productivity in Chaohu Lake area is analyzed.It is concluded that the daily yield,net production,respiration and P/R coefficient of the west half lake are higher than those of the east half lake.Therefore,the biomass of the west half lake is higher than that of the east half lake.
