中文摘要：

区域水文过程复杂性研究是一种新的研究模式，降水复杂性变化更是当前研究热点。运用等概率粗粒化的LZC方法，以红兴隆分局为例，对红兴隆分局辖区内10个农场逐月降水序列复杂性进行诊断，运用GIS技术绘制降水复杂性空间分布图。结果表明：八五三农场降水复杂性最高，八五二农场次之，五九七农场最低。进一步分析表明，降水是当地地下水埋深复杂性变化的主导影响因素之一。研究成果揭示了当地降水复杂性演变特征，为区域降水、地下水埋深准确预测及水资源合理优化配置提供了科学依据。

英文摘要：

Regional hydrologic process complexity is a new research mode, and the evolution characteristic of complexity of precipitati- on has been a hot topic. This paper diagnosed the complexity about monthly rainfall series of 10 farms in Hongxinglong Branch Bu- reau, based on equal probability coarse graining LZC. Using GIS technology drew a picture of complexity space pattern. The result showed that Bawusan farm was the most complex, Bawuer farm was less, Wujiuqi farm was the least. The follow-up analysis ex- plained that the precipitation was one of the main influence factors on the changes of underground water depth. The research findings have revealed the evolution of complexity of local precipitation, and provided scientific evidence for the forecast of regional rainfall and the depth of underground water and sustainable utilization and allocation of water resources.
