| 摘要: |
| 通过2006年7月至2007年5月首次对沂河流域水体浮游植物展开的周年调查,结果表明:该流域共有浮游植物7门73属181种及变种,以绿藻和硅藻种类最多,其中沂河7门137种、祊河7门134种、东汶河7门75种、蒙河6门67种、涑河6门70种、柳青河7门80种.应用污染指示种、污染指示群落和浮游植物综合指数评价沂河流域水质,综合评价其水质分别为:东汶河、涑河、蒙河、祊河和沂河均为β-中污,柳青河为α-β-中污;水质从优至劣排序为:涑河>东汶河>祊河>沂河>蒙河>柳青河.橡胶坝建设改变了沂河和祊河的水量时空调配,严重降低了其水流速度,导致浮游植物群落从河流相向湖泊相转变;对东汶河、蒙河、涑河、柳青河四条河流影响相对较小. |

| Abstract: |
| Water samples were collected by using standard methods at ten locations in Yi River watershed from July 2006 to May 2007. Yi River watershed contains 181 species and varieties, 73 genera, and 7 divisions of phytoplankton, among which Chlorophyta and Bacillariophyta are the most important component. Within the watershed, there are 137 species and varieties, and 7 divisions of phytoplankton in Yi River; 134 species and varieties and 7 divisions in Beng River; 75 species and varieties, and 7 divisions in Dongwen River; 67 species and varieties, and 6 divisions in Meng River; 70 species and varieties, and 6 divisions in Su River; and 80 species and varieties, and 7 divisions in Liuqing River. Water quality assessment was calculated by using saprobic indicator, saprobic indicator commuuity, and phytoplankton general index. Overall evaluation result of Yi River watershed water quality is: Dongwen River, Su River, Meng River, Beng River and Yi River are β-ms, and Liuqing River is α-β-ms. The water quality orders are: Su River> Dongwen River> Beng River> Yi River> Meng River> Liuqing River. Building rubber dams has changed the rearrangement of the water yield in Yi River and Beng River, which has reduced their streams speed greatly and caused the change of phytoplankton community from fluvial facies to the lake facies. However, it has less effect on Dongwen River, Meng River, Su River and Liuqing River, relatively. |
