【摘要】 在寒露风发生期间,通过建立逐日温度的空间计算模型,应用地理信息系统计算了江西省小网格逐日温度分布情况;再根据寒露风指标,进一步计算了不同地形下的寒露风灾害分布情况,并结合卫星遥感监测的晚稻种植地理分布数据,制作了全省寒露风灾害分布图,计算了各地寒露风受害面积,研究了一种新的基于3S技术的灾害分析评估方法。更多还原

【Abstract】 Space models of daily temperature are established during the cold-dew wind period,so sub-grid temperature distribution in Jiangxi province is mapped in accordance with the geographic information system.Using cold-dew wind index,the cold-dew wind disaster distribution in different terrain is calculated and combined with geographic data of late rice derived from remote sensing to produce the cold-dew wind disaster map and influence area.The new disaster evaluation method based on 3S technique is explored in this article.更多还原
