丘陵山区灌溉面积分布高程相差较大,灌溉水源较低。如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级提水,可直接灌田;边远地区要长距离自江河翻水上山。在翻水站级数及线路规划中着重论证了以下三个问题。
Hilly and mountainous areas of irrigated area distribution of the elevation difference is larger, lower irrigation water. Such as Jiangning County Cultivation elevation generally 30 meters below, up to 60 meters. Drought source is mainly taken from the Qinhuai River and the Yangtze River. Dry season tidal range of the Yangtze River about 5.5 meters, about 6 meters Qinhuai River water level of 25 to 55 meters. Hill and rolling hills, posts red wrong, terrain broken. Located near the river from 1 to 2 to mention water, can be directly irrigated fields; remote areas to long distances from the rivers into the mountains. In the water level of the station and line planning focused on demonstrating the following three issues.
