摘要
降水量是区域干旱评价的决定性因素之一。采用宜良县区域内10个雨量站近33年的实测资料序列,通过区域干旱风险模型、干旱缺水量模型的建立,对宜良县区域干旱风险及其区域干旱缺水量进行了分析。结果表明,宜良县区域受旱面积为57.49%时风险性最大,区域年平均缺水量为39 179.76×104m3。
Precipitation is one of the decisive factors in regional drought evaluation. This paper adopted the observed data at the 10 stations in Yiliang County during recent to analyze drought risk and water shortage by using the local drought risk and water shortage model. The result shows that there is the maximum risk when the drought area reach 57.49% of the total area in Yiliang County, and local average annual water shortage is391.7976 million m3.
