摘要
Abstract
[Objective] The research aimed to study the spatial and temporal variation characteristics of surface ALBEDO in the middle Yellow River based on remote sensing. [ Method] Based on the MODIS/MCD43B3 and the rainfall and temperature of weather stations data set from 2001 to 2010 years, used pearson correlation analysis and partial correlation analysis,the spatial and temporal variation characteristics of surface ALBEDO and the relationship between ALBEDO and rainfall and temperature of the Middle Yellow River. Were sudied. [ Result] The results indicated that the study area of ALBEDO has the feature of fluctuation change, the order of ALBEDO with different land-surface cover of the yearly average is: plantation > land of construction > grassland > forest land. The correlation between ALBEDO and rainfall and temperature is diversity in different terrain, land-surface cover type. [Conclusion] The study provides the theoretical basis for raising the level of long-term climate forecasting.关键词
