开封市棉花产量对气候变化的响应分析
Response Analysis of Cotton Output to Climatic Change in Kaifeng
摘要
Abstract
[Objective] To analyze the response of cotton yield to climate change and countermeasures. [ Method ] With mathematical statistics and fuzzy mathematics method to analyze the relationship between Kaifeng climatic change trend,light,temperature,water and cotton yield,create database. In the support of Excel software, using second order polynomial, cotton production, temperature, precipitation and sunshine time were separated into social quantity and climate of research. [Result] Accumulative temperature and cotton output in cotton growth period were both increase in Kaifeng. Climate warming was main influencing factor for cotton output; rainfall and cotton output showed increase trend,rainfall was greater than needed water in cotton growth period; sunshine hours decreased,cotton production would increase. The results showed that although sunshine hours had greatest effect on the quality and yield of cotton,it's not the crucial role. [Conclusion]Grasping climate change rule,adopting effective active measures,can reduce the loss caused by meteorological disasters.关键词
