摘要
采用作物模拟模型与气候变化情景耦合的方法，评价了全球气候变化对我国东北、华北和长江中下游平原大豆、产量和灌溉量的影响；还结合若干成功的农业气候指标和计算方法，分析了研究区域未来夏播大豆种植北界的地理位移，以及水分条件和大豆品质方面的变化等。对ＣＯ２浓度增加的直接生理影响也进行了考虑。
Usins an approach to link crop simulation model and climate change scenarios, the effects of global climate change on soybean, yield and irrigation requirement in the Northeast China Plain, the North China Plain and the Middle and Lower Valley of the Yangtze River were evaluated. Besteds, chanses in the northern limit for summer - sowing soybean, moisture condititon and soybean quanlity were analyzed, interms of several successful agroclimatic indices and mathematical methods. The direct effedts of CO2 on soybean yield were also considered.
