	%X Understanding how precipitation inter-annually
changes and its implication in agricultural drought and production change in winter wheat (Triticum aestivum L.) growth season is critical for crop production in China. MODIS Temperature-Vegetation Dryness Index (TVDI) and daily mean precipitation time series for the main growth season(Feb. to May) of winter wheat from 2000 to 2010
were used to analyze the distribution of trends of precipitation,
agricultural drought and winter wheat yield change respectively, and
relationships between them in North China region(Huang-huai-hai
region, HHH region), China. The results indicated that the trend of
precipitation in HHH region past 11 years was increasing, which had
induced generally corresponding decreasing trend of agricultural
drought and increasing trend of wheat yield, while the trend of drought
was spatially diverse. The study could provide a basis for agricultural
drought research during winter wheat season in HHH region under the
ground of climate change.
