鄱阳湖流域NDVI的时空变化及其与气候的关系
Spatial -temporal Changes of NDVI and Their Relations with Climate Factors in Poyang Lake Valley
摘要
Abstract
According to the data of 10 - day SPOT VEGETATION during 1998 ~ 2010, the variation trends of annual and seasonal NDVI in the Poyang Lake valley during this 13 years were analyzed by using the averaging method, and the spatial distribution characteristics of the NDVI change were studied by using the unitary linear regression method. The results indicated that: from the year 1998 to 2010, the annual average NDVI presented an increasing trend in the Poyang Lake valley, and it was significantly increased in the mountainous and hilly areas, moderately or slightly improved in the basin and plain area; while in larger cities the annual average NDVI reduced less and less (significantly, moderately, slightly, or little) from the central urban zone to suburban zone. The correlations between annual NDVI and annual precipitation, annual average air temperature were not significant, while those between monthly NDVI and monthly precipitation, monthly average air temperature were significant, its reliability was up to 95%.关键词
