人类活动对气象-水文干旱传递特征影响的识别方法、装置及系统

By using hydrological models and drought index sequence analysis, the impact of human activities on the meteorological-hydrological drought transmission characteristics is identified and quantified. This solves the problem of the difficulty in accurately identifying this issue in existing technologies, improves the accuracy of drought assessment and early warning, and optimizes water resource allocation.

Abstract

本发明公开了一种人类活动对气象‑水文干旱传递特征影响的识别方法、装置及系统，基于率定好的水文模型模拟无人类活动影响下研究区域的水文过程，获得无人类活动影响下的径流数据，计算出第一水文干旱指数序列；基于气象观测数据和水文观测数据，计算出人类活动影响下的气象干旱指数序列和第二水文干旱指数序列；基于气象干旱指数序列、第一水文干旱指数序列和第二水文干旱指数序列识别出干旱事件及其特征，计算出有人类活动影响和无人类活动影响情景下气象干旱事件向水文干旱事件传递的干旱传递特征；比较两种情景下的干旱传递特征得到人类活动对干旱传递特征的影响。本发明能够得到人类活动对气象‑水文干旱传递过程的影响程度，可为水资源的合理配置提供参考。
