【摘要】 本文利用2003年卫星遥感干旱监测资料和哈尔滨市土壤湿度资料,应用土壤热惯量法计算和分析了全省和哈尔滨市的受灾情况,同时提出了防治措施。研究表明:这种方法是目前对裸露地面进行干旱遥感监测中定量水平较高的,对裸露土壤湿度遥感精度可达到60%,根据农业气象观测规范,它可以给出土壤干旱的绝对等级。利用此方法,可以计算出哈尔滨市12个县(市)不同级别干旱灾害的分布情况。更多还原

【Abstract】 The situation of drought in Heilong jiang province and Harbin was calculated and anylsed using secondary planet remote sensing drought and soil humidity data in Harbin in 2003 by means of soil heat inertia,and put forward prevention and cure measure.The result shows:the method is higher on ration level that secondary planet remote sensing drought on bare surface is inspected,which precision is 60%,and absoluted grades on soil drought are given by agriculture meteorological observation criterion.The distribution of drought that are different grades in harbin 12 county (city) may calculated by using the means.更多还原
