Study on the Dynamic Change of Regional Water Level and Climate Based on Forecast Equation

Abstract Because there are too many factors affecting the change of hydrometeorological elements in the long term, it is necessary to use a single linear relationship to construct the forecast equation, which will omit too many forecast factors. Therefore, it is necessary to use a variety of nonlinear function types of correlation coefficient calculation and comparison, clear optimization of forecast factors to build the corresponding forecast equation. In this paper, we study spatial change of water in the understanding of trend test principle, analysis method and dynamic time series model, on the basis of based on regional water level change to build the corresponding forecast equation, the design and implementation of the regional water level change and climate dynamics forecasting system software, the empirical analysis found that the regional water level has a close relationship between dynamic change and climate change.
