掌握新疆天山北坡酿酒葡萄成熟期降雨特征,对科学制定酿酒葡萄种植规划,采取趋利避害的生产管理技术措施具有实际意义。基于天山北坡35个气象站1961-2016年8-9月逐日降雨资料,采用线性趋势法和ArcGIS空间插值技术,对过去56a该区域酿酒葡萄成熟期(8-9月)降雨日数、降雨量、连阴雨天气次数、连阴雨天气降雨强度等要素的时空变化进行研究,并对照前人关于该区域酿酒葡萄种植气候适宜性区划成果,对酿酒葡萄不同适宜种植区葡萄成熟期降雨特征及其影响进行分析。结果表明:天山北坡酿酒葡萄成熟期(8-9月)降雨日数、降雨量、连阴雨天气次数、降雨强度、大量以上降雨日数的空间分布均总体呈现随海拔高度的升高而增加的特点。1961-2016年,研究区酿酒葡萄成熟期除降雨日数总体以-1.16d·10a-1的倾向率极显著 (P=0.001)减少,大量以上降雨日数以0.07d·10a-1的倾向率显著 (P=0.05)增多外,降雨量、连阴雨天气次数、连阴雨天气日数及其降雨量变化趋势均不显著。天山北坡酿酒葡萄种植气候最适宜和适宜区葡萄成熟期的降雨量、降雨日数、连阴雨天气次数、连阴雨天气日数及其降雨量都很小,期间总降雨量大多不足40 mm、降雨日数少于20 d、大量以上降雨日数不足1 d、连阴雨天气次数少于0.3次、连阴雨天气日数少于5d、连阴雨天气降雨量不足25mm,该分区降雨量以及连阴雨天气少,对提高酿酒葡萄产量和品质十分有利。酿酒葡萄次适宜种植区葡萄成熟期降雨天气稍多,降雨量40~90 mm、降雨日数20~25 d、大量以上降雨日数1~2 d、连阴雨天气次数0.3~1.0次、连阴雨天气日数5~8 d、连阴雨天气降雨量25~40 mm,对酿酒葡萄产量和品质有一定不利影响。天山北坡8-9月降雨量90 mm以上、降雨日数30d以上、大量以上降雨日数2d以上、连阴雨天气次数多于1.0次、连阴雨天气日数8d以上、连阴雨天气降雨量40 mm以上的区域均在海拔1500m以上的山区,该区域恰恰也是酿酒葡萄不适宜种植区,因此对酿酒葡萄无影响。综上所述,新疆天山北坡酿酒葡萄种植区尤其是适宜及最适宜种植区葡萄成熟期的降雨量、降雨日数、连阴雨天气次数和日数都较小,且近56a稳定少变,因此,对该区域酿酒葡萄生产的影响较小。  相似文献

As global warming is scientifically and widely accepted, its impacts at regional scales are raising many questions for wine producers. In particular, climate parameters, especially temperature, play a decisive role in vine growth and grape ripening. An overview of expected climate change in terms of bioclimatic indexes (Winkler and Huglin) and thermal extremes in the wine-producing region of Champagne is presented. A variable-grid atmospheric general circulation model, ARPEGE-Climate, with a local zoom at 50 km over the area of interest, is used to investigate potential future changes in thermal extremes and bioclimatic indexes. Changes in daily maximum and minimum temperatures at key stages are discussed for three emission scenarios (B1, A1B, A2) that are currently used in studies of impacts of climate change. Model outputs are analyzed and critically assessed for a control period (1971–2000) and for changes in extreme events in relation to future scenarios, such as a decrease in extreme low temperatures in spring (April) during bud break and an increase in extreme high temperatures in summer, associated with more frequent heat waves during ripening.  相似文献

Climate Change and Global Wine Quality   总被引:10,自引:0,他引:10  
From 1950 to 1999 the majority of the world's highest quality wine-producing regions experienced growing season warming trends. Vintage quality ratings during this same time period increased significantly while year-to-year variation declined. While improved winemaking knowledge and husbandry practices contributed to the better vintages it was shown that climate had, and will likely always have, a significant role in quality variations. This study revealed that the impacts of climate change are not likely to be uniform across all varieties and regions. Currently, many European regions appear to be at or near their optimum growing season temperatures, while the relationships are less defined in the New World viticulture regions. For future climates, model output for global wine producing regions predicts an average warming of 2 C in the next 50 yr. For regions producing high-quality grapes at the margins of their climatic limits, these results suggest that future climate change will exceed a climatic threshold such that the ripening of balanced fruit required for existing varieties and wine styles will become progressively more difficult. In other regions, historical and predicted climate changes could push some regions into more optimal climatic regimes for the production of current varietals. In addition, the warmer conditions could lead to more poleward locations potentially becoming more conducive to grape growing and wine production.  相似文献

Changes in maximum spring and summer temperature are expected to have impacts on plant phenology and the occurrence of forest fires. Homogenised instrumental records of maximum spring and summer temperature are available in northern France for the past century, as well as documentary records of grape harvest dates and forest fire frequencies. Here we provide a new proxy of seasonal climate obtained by the analysis of latewood tree ring cellulose isotopic composition (δ18O, δ13C and δD), from 15 living oak trees (Quercus petraea) sampled in the Fontainebleau forest, near Paris. For the past 30 years, we have conducted a study on the inter-tree (for oxygen isotopes) and inter-station (for oxygen and hydrogen) isotopic variability. Multiple linear regression statistical analyses are used to assess the response function of documentary and tree-ring isotopic records to a variety of climatic and hydrological parameters. This calibration study highlights the correlation between latewood tree-ring δ18O and δ13C, grape harvest dates and numbers of forest fire starts with maximum growing season (April to September) temperature, showing the potential of multiple proxy reconstructions to assess the past fluctuations of this parameter prior to the instrumental period.  相似文献
