2.3 Data description

  • Yield records of buckwheat and naked oats during 1961-2010 at Wuchuan County;

  • Meteorological observations during 1961-2010;

    • maximum temperature, minimum temperature, average temperature, precipitation, sunshine hours

3 1 meteorological elements statistical analysis2

3.1 Meteorological elementsstatistical analysis

  • The minimum temperature , maximum temperature and average temperature increased in the past 50 years;

  • The precipitation and sunshine hours fluctuated greatlyand reduced in general during this period ;

3 3 sensitive analysis between yields and climatic elements

3.3 Sensitive analysis between yields and climatic elements

  • Climat1: temperature is the first typical variable;

  • Climat2: precipitation is the first typical variable;


3 3 sensitive analysis between yields and climatic elements1

3.3 Sensitive analysis between yields and climatic elements

  • Buckwheat and Naked oats are negatively correlated with the maximum temperature, minimum temperature and average temperature. There is a significant negative correlation between the maximum temperature and the yield. The correlation of buckwheat is more significant than that of naked oats.

  • Buckwheat and naked oats are positively correlated with the precipitation. The correlation of buckwheat is more significant than that of naked oats;

  • The buckwheat is positively correlated with the sunshine hours while the naked oats is negatively correlated with the sunshine hours.

4. Conclusions and discussion

  • The correlation between the yields of buckwheat and the meteorological elements is more significant than that of naked oats.

  • Temperature and precipitation are the main elements which affect yields of naked oats and buckwheat.

  • The yields of naked oats and buckwheat show great sensitivity to climate change and global warming.
