松江县地面高程在2.6m以下的土地4万余亩,习惯上叫作泖田,实则上就是低洼地。我们的内河水位一般都控制在2.8m以下。这就形成了内河水位高于地面的外部条件,特低地区的地面水无法自流排出田外,加上雨水多是我们的泖田成灾的主要原因。从1989年到1993年我们对石湖荡镇的西泖圩区、五厍镇河西泖田、小昆山镇的泖口进行了改造。其中以石湖荡镇的西泖圩区共
Songjiang County ground elevation 2.6m below the land more than 40,000 acres, habitually called 泖 Tian, in fact, is a low-lying land. Our inland water level is generally controlled below 2.8m. This creates an external condition where the inland water level is higher than the ground. The surface water in the ultra-low area can not be drained out of the field by gravity. Adding more rain is more the main reason for our disaster. From 1989 to 1993, we rebuilt Xikou polder area in Shihutang Town and Qiaokou in Hexi Xiongtian and Xiao Kunshan Towns in Wuyi Town. Among them, the town of Shek Pik town of Xidi polder area
