| Abstract: | In order to realize multi-scale dynamic monitoring of oriental migratory locust habitats and analysis of the factors driving the changes of locust habitats,our study combined remote sensing and geographic information system techniques to extract the spatial distribution data of locust habitats in Dagang reservoir,Tianjin in 2002,2006 and 2013 by using multi-temporal remote sensing images.The temporal and spatial variations in locust habitats were quantitatively analyzed at the scales of landscape(area change),pixel(multi-temporal binary coding method)and patch(landscape indices).The results showed that the area of locust habitat tended to increase from 329.98 km2in 2002 to 146.34 km2in2013.During 2002—2013,the patch number of locust habitat declined;the patch shape index and mean patch area decreased firstly and then increased,and the landscape fragmentation index first increased and then decreased,which indicated that the degree of landscape fragmentation was relatively high from 2002 to 2006 and relatively low from 2006 to 2013.The temporal and spatial variation in locust habitats could be quickly acquired with multi-temporal remote sensing images,which is conducive to the monitoring,early warning and scientific prevention and control of migratory locusts. |
