丘陵山区灌溉面积分布高程相差较大,灌溉水源较低。如江苏省江宁县山丘区耕种高程一般在30米以下,最高达60多米。抗旱水源主要取自秦淮河和长江。旱季长江潮位5.5米左右,秦淮河水位6米左右,提水高度25～55米。山河间为起伏丘陵,岗冲相错,地形破碎。离江河近处设1～2级站提水,可直接灌田;边远地区要长距离自江河反水上山。在提水站级数及反水线路规划中考虑节能,着重论证了以下三个问题。
There is a large difference in the elevation of the irrigated area in the hills and mountains, and the irrigation water source is relatively low. For example, the elevation of farmland in the hilly area of Jiangning County, Jiangsu Province is generally less than 30 meters and the maximum is more than 60 meters. Drought water sources are mainly from the Qinhuai River and the Yangtze River. In the dry season, the tide level of the Yangtze River is about 5.5 meters, the water level of the Qinhuai River is about 6 meters, and the elevation of the water is 25 to 55 meters. Between the mountains and rivers is the rolling hills, Gang Chong is in the wrong place, and the terrain is broken. From the river near the 1 to 2 station set up water, can directly irrigation; remote areas from long distances from the river against the water. Considering energy conservation in the water lifting station series and planning of the anti-water route, the following three issues were emphatically demonstrated.
