    摘要:

    芜申运河是重要的省际干线航道,规划对其整治达到三级航道标准后通航,而芜申运河通航需要固城湖上的通航河道开闸。固城湖为重要的饮用水源地,开闸通航对固城湖水量影响较大。通过建立模型计算得出,每天开闸10次固城湖水量损失约为1.71×108m3/年,每天开闸20次水量损失约为2.87×108m3/年;而固城湖的常态水位为9.5m,相应库容为1.28×108m3,通航对固城湖水量的年损失量占到了固城湖常态水量的1.342.24倍左右。如果开闸20次,固城湖需要外调补水以保证水量满足用水需求。经计算,在90%、75%、50%的降水保证率下,需要外调补水保证量达0.64×108、0.61×108、0.12×108m3/年,占固城湖常态库容的50%9%。

    Abstract:

    Wuhu-Shanghai Canal is an important inter-provincial trunk channel, and it was planned to renovate and meet Grade III standard navigable waterway. The Gucheng Lake is an important source of drinking water, and the Wuhu -Shanghai canal navigation will reduce the quantity of the Gucheng Lake substantially. In this study, the variation of water quantity in the Gucheng Lake after the renovation were calculated by modeling. The results show that opening-gate 10 times per day will result in the water losses of 1.71×108 m3 /a, and the loss is 2.87×108 m3 /a for 20 times per day. The normal water level of the Gucheng Lake is 9.5m, corresponding to storage capacity of 1.28×108 m3 . The Gucheng Lake will loss normal water quantity by 133.6% and 224% if the renovation is completed and open to navigation. In addition, if the gate open 20 times per day, the Gucheng Lake will have to supplement water quantity to meet the water demand. If the preparation reach 90% of that in normal year, the Gucheng Lake need 0.64×108 m3 supplement water per year,which is almost half of the storage capacity of the Gucheng Lake.
