The Grassland Locust Hazard Remote Sensing Monitoring And The Valuation Methods Research

Locust pest is the our country endangers the agriculture production and people life of three one of the great universe disasters. Went to 2004 in 1997 our country Xinjiang, QingHai, Inner Mongolia, GanSu, Tibet the steppe big area of the region of etc. took place the locust pest. Have become the most serious natural disaster in the steppe region, can keep on the development to constitute the serious threat to the steppe ecosystem environment and the steppe livestock husbandries.The Normal University remote sensing of Inner Mongolia and the geography information system key laboratories undertook in 2004 the weather remote sensing monitor estimate service system of the steppe locust pest the sub- topic of the item the steppe locust pest remote sensing monitor item , this thesis is a foundation that studies at that up complete of.This research chooses steppe region in Inner Mongolia as research object, monitoring the remote sensing conduct and actions to correspond the point, with the open country experiment is basis, went to 2005 to open the exhibition in the whole area scope on July 28 on June 7 in 2005 open country experiment work. The experiment mainly carries on the test to the environment condition (earth's surface temperature, soil degree of humidity, produce the amount of grass) that the steppe locust pest rely for existence. The explosion area of the choice main consideration steppe locust pest of the remote sensing data is big, descend the mat noodles piece is uniform, and the data of MODIS is cheap, the wave band scope is wide, the data resolution compare the NOAAAVHRR have the bigger improvement and can get everyday at least 2 times renewal data, to solid hour disaster monitor have the...
