| 1. | Zoobenthos investigation and water quality assessment in erlonghu reservoir 二龙湖水库底栖动物调查与水质评价 |
| 2. | Longgan lake represents natural fishing lake , having little effect on zoobenthos 尤感湖代表天然捕捞湖泊,可以认为天然捕捞对底栖动物的影响不大。 |
| 3. | Zoobenthos investigation and assessment of water quality in drinking water sources of five cities in jiangsu province 江苏五市饮用水源地底栖动物调查及水质评价 |
| 4. | Investigation of heavy metals and zoobenthos in jiangsu section of the yangtze river and ecological risk assessment 长江江苏段沉积物中重金属与底栖动物调查及生态风险评价 |
| 5. | Models using nonlinear optimization methods for the recognition of water quality classes by zoobenthos are proposed 把非线性最优化模式的模型用于过底栖生物来确定水质级别的方法被提出来了。 |
| 6. | The biomass of zoobenthos in four lakes existed differences but the differences were not distinct statistically ( p > 0 . 05 ) 四个湖泊底栖动物及其各类群生物量差异较大,但在统计学上未达显著界限。 |
| 7. | Zoobenthos were affected by mitten crabs in two ways : direct feeding on benthos and indirect effect through damage of submerged macrophytes 河吸对底栖动物的影响一是直接觅食,二是通过破坏水草间接影响。 |
| 8. | Taxonomic groups of zoobenthos were significantly correlated with biomass of submersed aquatic macrophytes , depths , secchi disk transparencies , total phosphorus and total nitrogen contents 底栖动物各个类群的现存量与水草生物量、水深、透明度、总磷和总氮的关系均较密切。 |
| 9. | The species number of zoobenthos in east tangsun lake , niushan lake , longgan lake and huang lake were 36 , 24 , 33 , and 18 , respectively . the differences in species richness and species diversity in the four lakes were obvious 主要结果如下:东汤孙湖、牛山湖、龙感湖、黄湖四个湖泊底栖动物的种类数分别为36 、 24 、 33 、 18 ,各类群的种类数以及生物多样性指数相差很大。 |
| 10. | For the relationships between zoobenthos and environmental factors , results showed that zoobenthic standing crops were positively correlated with submersed aquatic macrophytes , total phosphorus and total nitrogen contents but were negatively correlated with depths and secchi disk transparencies 环境分析表明底栖动物总的现存量与水草生物量、总磷总氮含量均正相关,与水深、透明度均负相关。 |
