南方季节性干旱成因及抗旱对策

连续三年在我国南方传统丰水地区发生的季节性干旱已严重危害了我国经济社会的和谐健康发展。因此，有必要对季节性干旱进行分析探讨，以利于更好地应对干旱及防灾减灾。分析了季节性干旱的成因及特点，对抗旱对策进行了思考。气候变化异常引起的降雨少、温度高是造成季节性干旱的主要原因，水利设施的不完善加剧了干旱的危害。今后在继续发挥已有水利设施抗旱作用的同时，必须狠抓水源工程建设，确保有水可用；严格水资源管理分配，实现用水合理；推广节水技术，提高水资源利用率。

The Causes And Countermeasures of Seasonal Drought in South China

Last three years, seasonal drought in south china has seriously harmed the harmonious and healthy development of our social and economic. Analysis of seasonal drought will be useful to cope with drought and reduce the drought disaster. The causes and characteristics of seasonal drought and the drought response were analyzed in this paper. Less rainfall and high temperature, which caused by anomaly climate changes, is the main reason of season drought, imperfect water conservancy facilities aggravated the drought damage. In the future, drought resistant function of water conservancy facilities should be continually played, at the same time, vigorously promote the water projects construction to ensure water available; enforce management and allocation of water resources to realize rationalize water use; generalize water-saving technology to improve the water utilization rate.
