【题目】近几年,新疆建设兵团在中科院的帮助下成功地利用无人遥控直升机对所属农场的农作物病虫害进行了防治,大大提高了其准确度和工作效率。据此回答下列问题。
【1】工程技术人员指挥无人遥控直升飞机运用的地理信息技术是
①RS ②GPS ③GIS ④数字地球
A.①② B.③④ C.②③ D.①④
【2】对农作物病虫害的监测,新疆采用了卫星遥感技术,是因为
①.农作物遭受病虫害时,发射和反射的波谱会有一定变化
②.卫星遥感分辨率高,可拍摄到清晰的照片
③.卫星遥感探测的范围广,连续性强
④.卫星遥感智能化高,在治虫过程中无需人工参与
A.①② B.③④ C.①③ D.②④
【答案】
【1】A
【2】C
【解析】
试题分析:
【1】RS是遥感技术,对地理事物进行动态的监测,可以监测作物病虫害分布状况;GPS可准确定位,进行除虫;GIS是分析、查询、评价过程,可以分析病虫害的状况,但不能指挥精准除虫;数字地球是“3S”技术+互联网,是在网络上共享资源,不能指挥除虫。选A正确。
【2】卫星遥感技术通过获取地理事物的电磁波信息,来判断地理事物的性质;卫星遥感技术应用在农作物遭受病虫害时,发射和反射的波谱会有一定变化,①正确;卫星遥感探测的范围广,连续性强,③正确;卫星遥感相对近地面遥感分辨率低,②错;卫星遥感提供的是地理信息,人类通过信息分析,才可进行治虫,④错。选C正确。
