Chinese Abstract

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。

English 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.
