摘要
利用遥感手段进行作物种植面积监测是国家保障粮食安全的基础性措施之一。以2010年度黑龙江地区大豆种植面积遥感监测为例,利用抽样的方式对遥感监测样区进行面积监测,在抽样样方监测调查的基础上对遥感监测样区的结果进行修正,对比2009年黑龙江地区大豆种植面积监测的结果,得出2010年黑龙江地区大豆种植面积相比2009年减少3.17%,原因主要是经济因素。
Using RS Technology to monitor crop planting area is one of the basic measures.This paper takes example of RS monitoring soybean planting area in 2010 in Heilongjiang province.Taking sampling method to monitor the RS sample plot,correcting the RS monitor sample plot result according to sampling quadrat.Then compared with the soybean planting area last year in Heilongjiang province to obtain that Heilongjiang province soybean planting area reduced 3.17% compared with 2009.The reason for it was economic factor.
