摘要
以MODIS数据和气象数据为数据源,用偏相关和复相关分析、趋势分析、残差分析及驱动分区法,从生态区和时空尺度分析2001—2015年华北平原植被覆盖度变化及与气候、人类的关系。基于像元的小样本分析跟以往把整个研究区作为统计单元相比更能体现空间差异性。
Based on MODIS and meteorological data,a linear regression analysis,correlation analysis,partial correlation analysis,multiple correlation analysis,residual analysis and driving zoning were used to study the change of vegetation cover in the North China Plain in the past 15 years（ 2001—2015）.According to the analysis of different ecological zones,the vegetation coverage of North China Plain showed an upward trend with the interannual change.
