Description :
The AA. investigated the responses of cropland phenophases to changes of agricultural thermal conditions in Northeast China using the SPOT-VGT Normalized Difference Vegetation Index (NDVI) ten-day-composed time-series data, observed crop phenophases and the climate data collected from 1990 to 2010. For the extracted length of growing season and the observed growth period, notable correlations were found in almost same regions. However, there was no obvious correlation between the end-of-growth date and the first frost date in the study area. The results indicated that the crop growth periods were shortened because of the elevated temperature; in contrast, the extended growth period usually meant a crop transformation from early- or middle-maturing varieties into middle or late ones.
