Effect of Changes of Temperature and Precipitation Trend on Agricultural Production in 50 Years at Chaoyang District in Liaoning
[Objective] The study aimed to master the changes of heat and water resources in Chaoyang district, and offer basis for adjusting structure and avoiding-disaster. [Method] Though applying the method of common mathematical statistics, the increasing extent of factors of heat resource were resolved by linear asymptote in Escel procedure.[Result] The warming extent of 3 district in Chaoyang existed differences , average temperature increased 0.8 - 1. 9℃ , and that in winter was the most obvious; the annual precipitation induced 50 millimeter, and mainly in summer from 1960 to 2008. [ Conclusion] The temperature increase and precipitation decrease had different effect on agrometeorolo-gy resources and disaster, and had both advantages and disadvantages in agricultural production.
