补充资料：滦河
| 滦河 位于中国河北省东北部。发源于河北省丰宁满族自治县西北的巴颜图尔古山麓。流入内蒙古自治区称闪电河，在多伦县附近，有上都河注入称大滦河，经两度曲折，转回河北省，在郭家屯附近汇小滦河后称滦河。此后，干流呈东南向，横穿燕山和冀东平原，最后在乐亭县、昌黎县间注入渤海。全长833千米，流域面积4.49万平方千米。水系发育，常年有水的支流500多条。主要支流有伊逊河、青龙河等。多年平均年径流量46.3亿立方米，但分配不均匀。水力资源理论蕴藏量59.64万千瓦。由于流域植被覆盖较好，河水含沙量（滦县站）多年平均仅4.73千克／立方米。干流上已建有潘家口水库、大黑汀水库。1983年引滦入津工程全长234千米，是中国最长的引水工程（截止1995年），平均每年向天津市输送8.1亿立方米的淡水。 |
