摘要
利用醴陵市1956—2012年气象站及近年来区域自动站降水资料,采用《湖南省地方气象灾害术语与分级》中的干旱标准,分析了醴陵干旱发生时空规律,发现醴陵干旱灾害呈现冬春干旱出现几率少,夏秋干旱发生频率高;西部干旱重于北部,农业灾损严重的特点。并结合作物布局和水利设施实际情况,认为醴陵干旱主要与气候、地理位置、水系特征与土质状况、农业种植业结构、现有水利工程及设施、人类活动等因素有关。根据干旱形成的原因,提出了加强现有抗旱基础设施建设和管理、实施"生物治水工程"、科学调整农业种植业结构、发展节水农业、加强旱情测报和预报等应对措施。
Based on the data from meteorological stations and regional auto-matic weather stations in Liling City from 1956 to 2012, temporal-spatial occur-rence laws of drought in Liling City were analyzed according to the standards specified in Hunan Local Meteorological Disaster Terms and Classification. Drought disasters in Liling City show the following characteristics： less in winter and spring, more in summer and autumn;more in west than in north; causing seri-ous agricultural losses. Considering crop layouts and water conservancy facilities, this paper proposed that drought disasters in the local area were related to climate, geographical location, water system characteristics and water quality, structure of agriculture and farming, existing water conservancy projects and facilities, human activities. According to the drought causes, corresponding measures were given, such as enhancing construction and management of drought-resistant infrastructure, applying “biological water control”, adjusting structure of agriculture and planting industry, developing water-saving agriculture, enhancing drought forecast and warning etc..
