| 摘要: |
| 1997年 4月至 1998年 1月,在浮桥河水库 14个采样点调查底栖动物,共获 47种.其优势种类为霍甫水丝蚓 (Limnodrilus hoffmeisteri)、中国长足摇蚊 (Tanypus chinensis)、前突摇蚊属 (Procladius sp.)和摇蚊属 (PChironomus sp.).水库底栖动物的Shannon指数和Margalef指数偏低,上游的指数值最高.从种类相似性来看,底栖动物的季节变化不明显;在水平分布上,上游与库汊的种类相似性最低,库汊与下游的种类相似性最高.浮桥河水库底栖动物的平均密度为529.1ind/m2,平均生物量为 3534.1mg/m2,均以水生昆虫占优,其时空变化主要受水生昆虫控制.能量估算法估算出浮桥河水库底栖动物的渔产潜力为 1.5×104 kg/a. |

| Abstract: |
| During the investigation from Apr.1997 to Jan.1998,a total of 47 species of zoobenthos were recorded at 14 sampling stations in Fuqiaohe Reservoir, Hubei Province, of which Limnodrilus hoffmeisteri, Tanypus chinensis,Procladius sp.and PChironomus sp.were dominant species.The Shannon index and the Margalef index were lower with the peak in the upper reaches.Changes of zoobenthos similarity coefficients in different seasons were not significant.In horizontal distribution the similarity coefficient between the upper reaches and the cove was the lowest and the highest between the lower reaches and the cove.The density and biomass of zoobenthos in the reservoir were 529.1 ind./m2 and 3534.1mg/m2,respectively and both dominated by Insecta.The spatiotemporal change of the zoobenthos standing crops was mainly related to Insecta.It was calculated that the fish production potential from zoobenthos was 1.5×104kg/a It is suggested studies on zoobenthos as an indicator for trophic classification in reservoirs should be conducted. |
