Abstract
2019年8月对韶关北江特有珍稀鱼类省级自然保护区内水域开展了浮游植物、浮游动物、底栖动物等调查,共发现浮游植物种类6门67种(属),浮游动物68种(属),大型底栖动物3门27属(科).浮游植物种群丰度为6.41×105~11.03×105 cells/L,Shannon-Wiener多样性指数为2.226~2.803;浮游动物种群丰度为54~151.25 ind/L,Shannon-Wiener多样性指数为2.814~3.244;底栖动物种群丰度的变化范围为18~102 ind/m2.表明:韶关北江特有珍稀鱼类自然保护区内水体为中营养型,生物多样性指数一般,水体环境质量中等,水体受污染程度较低.
