摘 要:报道了2001年5、7、9月黑龙江中游水域理化特征和季节变化动态。结果表明:该水域水质基本处于良好状态,其透明度均值为41cm,pH均值为7.4,水中溶解氧丰富,水型属重碳酸盐类,钙组Ⅰ型(C1Ca)和软水。水中主要营养元素含量较高,总氮均值为0.452mg/L,磷酸盐含量均值为0.113mg/L。水中多数理化组分在平面和季节分布上有所差异,但差异不明显。本文对水质理化特征与季节变化和主要理化指标、营养状况及其与鱼类为主的水生生物的相关性进行了讨论和评价,为发展水产业和持续利用渔业资源提供一定的理论基础依据。The physico-chemical characteristics and seasonal changes of middle reaches water in Heilongjiang River were studied in May, July and September in 2001.The results showed middle reaches water in Heilongjiang River had good water quality, with tansparency mean 41cm and pH value 7.4. The dissolved oxygen was rich,and the water belongs to ClCr and soft water.The contents of major nutrient elements were high,the content of TN in water was 0.452mg/L,and the content of phosphate was 0.113mg/L.There were hydrobgial and seasonal changes of the physico-chemical characteristics of middle reaches water in Heilongjiang River,but changes did not occur markedly. The water quality changes of different seasons and major physicochemical factors, nutrient state and the correlation were discussed and assessed.This study provides a theoretical basis for fishery and sustainable use of fishery resources.
