摘要
根据1989年赵宗慈用美国大气环流模式输出结果计算出的当CO_2倍增时我国地面温度和降水量变化情况,得出CO_2倍增时河北省温度和降水的输出结果,分析了CO_2倍增时河北省棉花生长季内气候变化的可能性及其对棉花分布、种植结构、产量、品质和对病虫害的影响。结果表明,CO_2倍增后河北省棉花种植区域扩大,复种指教增加,产量质量有不同程度的提高,有些病虫害的发生将趋干严重,而有些病虫害则可能趋于缓解。
Based on the results calculated by Zhao Zongci,who used the GCM models from USA to forcast the possible changes of land surface temperature and precipitation in China when doubled CO2 occurred,the possible climate change during cotton growth period in Hebei Province and its influences on cotton distribution,planting pattern,yield,quantity,disease and insect pests were initially predicted under doubled CO2 condition. The results indicated that under doubled CO2condition, the regions suitable for cotton growth would be enlarged,multiple crop index would be increased,yield and quantity of cotton would be also raised; damage of some cotton disease and insect pests might be heavier,that of others might be lower.
