Abstract

Phenology consistency information was extracted from MODIS NDVI time series data of plain sin-gle-rice district northern Zhejiang.NDVI time series data were treated using discrete fourier transformation method in order to rectify the wrong data.Land use map was used to derive the NDVI time series data of cultivated land in study area.Maximum values of time series data per pixel were extracted to make analysis about the regional crop phenology characteristics.The result showed that rice had better phenology consis-tency than rape and wheat,and phenology information got from 8days composite data was more detailed than that from 16days composite data.Growing period response of rice to NDVI time series was much bet-ter than that of rape and wheat.The result indicates that the potential senses of MODIS NDVI time series to analyzing regional crop phonologies.
