| 1 | Influence of Climate Change on Winter Wheat Growth in North China During 1950-2000显示文摘The crop model World Food Studies (WOFOST) was tuned and validated with meteorological as wellas winter wheat growth and yield data at 24 stations in 5 provinces of North China from 1997 to 2003.The parameterization obtained by the tuning was then used to model the impacts of climate change onwinter wheat growth for all stations using long-term weather data from 1950 to 2000. Two simulations weremade, one with all meteorological data (rainfed) and the other without water stress (potential). The resultsindicate that the flowering and maturity dates occurred 3.3 and 3 days earlier in the 1990s than that in the1960s due to a 0.65° C temperature increase. The simulated rainfed yields show that the average droughtinduced yields (potential minus rainfed yields) have decreased by 9.7% over the last 50 years. This is tobe compared with a 0.02% decrease in yield if the precipitation limit is lifted. Although the precipitationduring the growing season has decreased over the last 50 years, the drought effects on the rainfed yieldsremained to be practically unchanged as the spring precipitation did not decrease markedly. | 宋艳玲 Elisabeth SIMELTON 陈德亮 董文杰 | 2005 | Acta meteorologica Sinica2005，19，4： | 5 |

| 12 | 气候和人为因素对黄土高原地区小麦生产的影响显示文摘为量化气候和人为因素对黄土高原地区小麦产量的影响,找到减少干旱对小麦生产影响的途径,利用气象数据和多种来源的作物数据模拟了1955~2004年冬小麦产量。结果表明,黄土高原地区的降水量、和蒸散量在1960~2000年间,以每10年高达20mm的速度减少,并且自20世纪90年代以来气温上升加剧了土壤水分的亏缺,但黄土高原稳定的春雨降低了气温上升带来的影响。在过去的50年里,人为因素(非气候,技术进步)对小麦总产量的走向起了决定性作用,然而最近10年来,模拟结果显示,气候影响已经上升到了60%,达到每10年每公顷300kg(总量约500kg)。现代农业中重型农机具的使用对黄土土壤质量和小麦产量都有不良影响。相反,免耕措施与小麦秸秆覆盖改进土壤水分平衡及其再分配,不仅增加了作物产量,而且降低了减产的风险。 | Elisabeth Simelton 张树兰 杨学云 | 2008 | 麦类作物学报2008，28，6： | 1 |
