2007年实现杭嘉湖水文巡测区域大包围。通过对2007—2010年包围区域进出水量分析,入境水量均小于出境水量,尽管相对误差在标准允许值范围内,但其绝对误差约为10亿~15亿m3/a。进一步提高测验精度,查找误差来源,提高杭嘉湖巡测水量精度,值得探讨。
2007年實現杭嘉湖水文巡測區域大包圍。通過對2007—2010年包圍區域進齣水量分析,入境水量均小于齣境水量,儘管相對誤差在標準允許值範圍內,但其絕對誤差約為10億~15億m3/a。進一步提高測驗精度,查找誤差來源,提高杭嘉湖巡測水量精度,值得探討。

Hydrometric Tour Gauging covered the entire area of Hangjiahu Plain.Water quantity statistics of inflow and outflow in this area showed the quantity of inflow was less than outflow.Although the relative error was in the value range of standard,the absolute error of about 1.0~1.5 billion m3/a.Improving accuracy of test and analyzing error source for increasing the accuracy of flow measurement by tour gauge in Hangjiahu plain was worth discussion.
