摘要: 基于数学统计方法,从案例研究入手,研究了1978—2008年中国十省主要农业气象灾害动态及其空间分布特征,评价了农业气象灾害成灾面积风险。结果表明,旱灾是中国最主要的农业气象灾害,而霜冻成灾面积年际间波动最大。在区域分布方面,旱灾受灾风险体现为东部省份高于西部省份,北部省份高于南部省份;长江中下游地区和东北地区省份遭受洪涝的风险较高,而西北地区省份的风险较低;青海省是风雹的重灾区。各省主要农业气象灾害成灾面积风险差异较大,旱灾和洪涝成灾面积风险高于风雹灾和霜冻灾。

关键词: 中国, 农业气象灾害, 成灾面积, 风险

Abstract: Ten provinces in China were chosen to assess the dynamics and impact of agro-meteorological disasters in 1978-2008 by the application of agricultural statistical data on statistical methods, and the spatial risk distribution of agricultural disasters were analyzed. The results show that drought disaster was one of the most important disasters in China; however, a high temporal variation was observed in the frost disaster areas. In terms of spatial variation, the risk of drought disaster in the eastern provinces was higher than that in the western, the northern provinces higher than the southern; high flood disaster risk mainly occurred in the Yangtze River region and the northeastern region in China; Qinghai Province in Tibetan Plateau had a high risk in hail disaster. There were large differences in the risk probabilities of four agro-meteorological disasters in China. The probabilities of drought and flood disasters were much higher than those of frost and hail disasters.

Key words: China, agro-meteorological disaster, disaster area, risk
