| 摘 要： | 利用黔西南州近50年气象资料对降水量的时空分布特征进行了分析。结果表明,黔西南5~10月（雨季）降水量占年降水量的82%~85%,而头年11月到次年4月（旱季）的降水量只占15%~18%,有长达6个月的少雨干旱期,即季节性缺水期;旱季降水量有减少、旱灾有加重的趋势。并分析了工程性缺水的现状,提出了有关的对策建议。

| Abstract: | The meteorological data in recent 50 years in Southwest Guizhou were used to analyze the temporal-spatial distribution characteristics of precipitation.The results indicated that the precipitation(rainy season) during May–October accounted for 82%-85% of annual precipitation,however,the precipitation from November of last year to April of the next year(dry season) only accounted for 15%-18%,there was rainless dry periods for 6 months,namely seasonal water shortages;the precipitation of dry season showed decreasing trend and drought showed increasing trend.Finally,the present situation of engineering shortages was analyzed and some suggestions and countermeasures were put forward. |
