| 中文摘要: |
| 本文基于区间化变量理论，研究了珠江三角洲网河区的水位空间变异性。给出了描述该网河区水位空间分布结构的半变异函数；揭示了该地区水位的空间结构性—方向性和相关距离。分析了该网河区水位的空间分布。提出了珠江三角洲河网水位空间插值的克里格方法，并给出了丰水期的一个应用实例。计算结果表明了该网河区水位空间分析的克里格方法的可行性。 |
| 英文摘要: |
| Based on the theory of regionalized variable the spatial variability of water levels in the river net of Pearl River delta in flood season was analyzed. The semi-variagram describing the spatial distribution structure of water levels was deduced. The directionality and the range of correlation for the water levels were revealed. The spatial distribution of water level in the river net was analyzed. The approach to spatial interpolation of water level by means of Kriging method is proposed. An example of application is given. |
