摘要:

论述场时间序列 (时空序列) 分析问题的提出以及理论基础,并在此基础上,根据状态空间重构理论和嵌入定理,参考单变量时间序列状态空间动力学预报模式,给出场时间序列的动力学预报方法的基本思想和预报思路,并尝试应用于我国华北地区5年、10年和20年尺度旱涝的长期预测试验中。初步的预测结果表明,场时间序列方法对其有一定的预测能力;我国华北地区5年及20年的旱涝等级为正常,近10年的旱涝等级为正常略涝。

关键词: 时间序列, 华北, 旱涝

Abstract:

Methodology and theoretical basis of the spatial-temporal series analysis is discussed in this paper, based on the phase space reconstruction theory and Taken's embedding theory, according to the prediction method of the phase space dynamics reconstruction theory for single variable time series, the dynamics prediction idea and method of the spatial-temporal series analysis is conducted then, which is also used in the long-term prediction of 5-, 10- and 20-year scales of drought and flood in the region of northern China. The preliminary results are as follows: to a certain degree, the method of the spatial-temporal series analysis has the predictable ability, and the dryness and wetness grades for 5- and 20- year scale on northern China are as normal, the dryness and wetness grades for 10-year scale in this region is a little wet above the normal.

Key words: spatial-temporal series analysis, flood and drought, northern China
