摘要
报道了 1 981～ 2 0 0 1年对中国三北地区内陆盐水生物资源调研的结果。总计对大约5 0个水体进行了采样调查 ,其中盐度为 0 8～ 2 86 0 ,碱度 1 75～ 6 7 0 0mmol/L ,pH 7 3～ 1 0 6 ,离子系数 0 45～ 6 7 0 0。共见到浮游植物 1 3 2种和变种 ,浮游动物 1 93种 ,底栖动物 3 1种 ,鱼类 3 7种。根据出现率和平均生物量 ,有 3 3种浮游植物、 3 4种浮游动物和6种底栖动物为三北地区内陆盐水的主要种类。此外 ,还讨论了浮游生物对盐度、碱度和pH的适应性、内陆盐水生物资源的渔业利用以及利用盐水或耐盐性淡水枝角类作为海水鱼苗活饵料的前景。
This paper is a review on the results of the investigation of biological resource from inland saline waters in North China during 1981-2001. At some 50 localities with salinity of 0.8-286.0, alkalinity of 1.75-67.00 mmol/L, pH values of 7.3-10.6, ionic coefficient of 0.45-67.00, there were 132 species phytoplankton, 193 species of zooplankton, 31 species of zoobenthods and 37 species of fishes. According to the rate of occurrence and the average biomass, 33 species of phytoplankton, 34 species of zooplankton and 6 species of zoobenthods were the important species in the inland saline waters in North China. Adaptability of plankton to the salinity, alkalinity and pH value, fishery exploitation of biological resources in inland saline waters and use of halophiles or salt tolerant freshwater cladocera as live food for marine fish larvae were discussed.
