文水县气候变化对玉米产量的影响
Effects of climate change on corn yield in Wenshui county
摘要
Abstract
[Objective] To explore the influence of climatic factors on the yield of corn and predict the yield of corn under the circumstance of future climate change.[Method] According to the climate data of monthly temperature,precipitation,evaporation,sunshine duration and the yield data of corn from 1998 to 2014,corn yield under long time series climate change in Wenshui county was analyzed by using mathematical statistics,regression analysis,Principal Component Analysis and Thornthwaite Memoriae model.[Results] During the last 17 years,the temperature and sunshine duration in corn growing period in Wenshui county showed fluctuational trend of descending,while the precipitation and evaporation rate showed an upward trend.The yield and climate yield of corn in the same period kept increasing.[Conclusion] The rise of temperature was inconducive to the increase of the yield of corn;much precipitation was favorable to the production of corn there were three components that affected the yield of corn in Wenshui County:temperature,moisture and extreme climate,The study showed that:"warm and wet" and "cold and wet" climate type were conducive to the increase of the yield of corn,"warm and dry" and "cold and dry" climate type were unfavorable to the yield of winter corn.关键词
