Groundwater shortage has become a very serious problem in Sanjiang Plain. More and more
so-called “funnels” and “hanging pumps” situations occurred due to water shortages. The overall trend of
groundwater level has decreased continually over the years. In this study, the Chuang Ye Farm in Jian
San Jiang Department was taken as an example to develop a non-stable time series random model by
applying the random analysis method. The model was used to simulate the dynamic variation and
forecast the trend in the future. This study aims to provide a better understanding for the sustainable
development of agriculture and use of groundwater resources. [Nature and Science. 2004;2(3):55-61].
