摘要: 采用水稻生育生理生态综合模型ORYZA1,模拟分析了未来15种可能气候变化对浙江省水稻产量的影响结果表明,CO2浓度的增加将使水稻增产,温度增加将导致水稻减产虽然CO2增加和相应增温对各季水稻产量在各地区的影响表现不同,但在不考虑温室效应将同时导致旱涝和病虫害变化条件下.GFDL、GISS和UKMO模型预测的气候变化将使浙江省全年水稻产量分别平均增产9.53%、8.92%和0.04%.

Abstract: Acomprehensive process-band model ORYZA1 was used to simulate the impact of 15 cases ofprobable climate changes on rice yield in Zhejiang Province. Thc results show that CO2 concentration increase could result in the grain yield increase, whereas the rdevant temperature increase could decrease it. The impact of CO2 concentration and relevant temperature increases onrice yield varies among regions. However, when the changes in rainfall and crop pest status areneglected, the annual rice yield could increase by 9. 53, 8. 92 and 0. 04 % under the climatechanges predicted by GFDL, GISSand UKMOmodels, respecitively.
