三江平原井灌水稻区地下水动态变化规律研究

Study on Dynamic Variation Regularities of Groundwater in Area of Well Irrigation Paddy in Sanjiang Plain

由于水田面积迅速增加,导致三江平原井灌水稻区地下水位持续下降,吊泵、局部超采现象时有发生。为解决上述问题,以853农场为例,采用时间序列分析方法建立了853农场地下水埋深动态预测模型,对地下水埋深进行模拟和预测,揭示了该区地下水动态变化规律,为三江平原地下水资源的可持续利用提供了科学依据。

The rapid increase of paddy field acreage has led to continually descending of groundwater level in area of well irrigation paddy in Sanjiang Plain. More and more hanging pump and partial overpumping have been occurring in area of well irrigation paddy. In order to solve above-mentioned problems, this paper took 853 Farm as example, built up the groundwater embedment depth dynamic forecast model of 853 Farm through applying the method of time-series analysis. Through using this model, this paper simulated and forecast groundwater embedment depth, revealed the groundwater dynamic variation regularities of this area. This paper can provide scientific gist for sustainable development of groundwater resource in Sanjiang Plain.
