气候变化对水稻生长影响的模拟分析
Simulation of Climate Change Impacts on Rice Yields
摘要
Abstract
Based on the General Circulation Model（HadCM3） and Statistic Downscaling Model（SDSM）,the future climate was simulated in ZIS in scenario A2 and B2.Based on the ORYZA2000,the rice growth was simulated in those climate scenarios.In terms of rice production and environment pollution,the feasibility of different kinds of water and nitrogen managements was discussed in those climate scenarios.It showed that the results of SDSM were quite close to the observation on temperature,precipitation,and sunshine duration.In scenario A2,gains yield decreased and irrigation and nitrogen fertilizer use ratio increased.In scenario B2,rice product on great benefit,both grains yield and use ratio of water and nitrogen increased.Increasing CO2 concentration would help increasing grain yield and dry weight of rice,and the yield of different managements was getting close.The most applicable management for both the scenarios was AWD combined with 4 times nitrogen application.关键词
