摘要
平原井灌区可划分为两类区块:村镇驻地区块和农田区块,两类区块地下水位动态特征存在明显差异。通常村镇驻地区块地下水位高于农田区块,形成地下水丘;村镇驻地区块地下水位年变幅小于农田区块;村镇驻地区块地下水位变化相对平缓,而农田区块地下水位常有陡坎,呈阶梯状。根据不同类型区块地下水位动态特点,提出了平原井灌区地下水位监测站点代表性的差异,和选取监测站点的方法。
The well irrigated area in the plains can be divided into two kinds, including the place where villages and towns are located, and the farmland location. The characteristics of groundwater level in these two locations are different. Commonly in water table at the farmland area is lower and higher in the village location with a mound shape. This paper presents a method for locating water table monitoring stations in well irrigated plain area.
