| 摘 要： | 基于多时相遥感信息可以有效反映区域尺度上作物物候期特征的原理,利用1998—2009年期间的SPOT/VGT NDVI逐旬时间序列数据,采用TIMESAT软件集成的非对称高斯函数拟合方法对数据序列进行平滑重构处理,进而根据拟合曲线变化特征定义并提取了我国东北地区耕地生长季特征参数（包括生长季开始期、峰值期、结束期与生长...

| Abstract: | The authors investigated spatio-temporal patterns of seasonality parameters of crop growing season in Northeast China,by using the SPOT/VGT NDVI ten day composed time-series data collected from 1998 to 2009.First,to minimize the effects of anomalous values caused by atmospheric haze and cloud contamination,the software TIMESAT was used to generate smooth time series of NDVI based on an asymmetric Gaussian function;second,the seasonality parameters,such as the start date,the end date,the peak date,and length... |
