干旱是自然现象,是由于局部地区无雨或少雨导致的土壤和空气干燥。随着社会的进步、经济的发展,水资源短缺现象日趋严重,加上近些年局部极端灾害性天气频繁发生,旱灾和洪灾一样越来越受到人们的重视。本文就2011年的干旱情况,从降雨、径流、地下水、蒸发、墒情等方面进行总结和分析,希望对今后的工作有所帮助。
Droughts are a natural phenomenon due to soil and air dryness caused by no rain or light rainfall in some areas. With the progress of society and the economic development, the phenomenon of water shortage has become increasingly serious. In addition, due to the frequent occurrence of some extreme disastrous weather in recent years, more and more people are paying attention to the drought and flood. This article summarizes and analyzes the drought situation in 2011 from the aspects of rainfall, runoff, groundwater, evaporation and soil moisture, hoping to be helpful for future work.
