Applying Non-stable Time Series Model to Forecasting the Groundwater Dynamic Varies in Area of Well Irrigation Rice in Sanjiang Plain
非平稳时序模型在三江平原井灌水稻区地下水动态变化中的应用

Recently, the problem of shorting of groundwater resources is rather serious in San Jiang Plain. More and more funnel and "hanging pump" appears. The groundwater level descends continually. So, the paper takes Jiang San Jiang Department Chuang Ye Farm as the example, through applying the method of random analyze to building up the non\|stable time series random model. Through using this model, the paper simulates the dynamic varies and forecast the varied trend in the future. The authors want to provide some references for the sustainable development of agriculture and groundwater resources.
