摘要
采用统计学方法以及ArcGIS的精细化空间插值技术,对1961—2016年天山北坡酿酒葡萄成熟期(8—9月)降雨日数、降雨量、连阴雨天气次数及连阴雨天气降雨量等要素的时空变化进行研究,并结合前人关于该区域酿酒葡萄种植气候适宜性区划成果,对不同适宜种植区酿酒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呈现随海拔升高而增加的特点。过去56 a研究区酿酒葡萄成熟期除降雨日数以-1.16 d/10 a的倾向率极显著(P=0.001)减少、大量以上降雨日数以0.07 d/10 a的倾向率显著(P=0.05)增多外,其他降雨气候要素变化趋势均不显著。该区域酿酒葡萄最适宜、适宜和次适宜种植区成熟期降雨量大多不足90 mm,降雨日数少于25 d,大量以上降雨日数不足2 d,连阴雨天气次数少于1次、连阴雨降雨量不足40 mm,这对提高酿酒葡萄产量和品质均十分有利。而8—9月降雨量达90 mm以上,降雨日数30 d以上,大量以上降雨日数2 d以上,连阴雨天气次数多于1次,连阴雨降雨量40 mm以上的区域均在海拔1500 m以上的酿酒葡萄不适宜种植区,对酿酒葡萄基本无影响。
Using statistical methods and ArcGIS refined spatial interpolation technology,this paper studied the temporal and spatial changes of elements such as the number of rainfall days,the amount of rainfall,the number of cloudy and rainy days and the amount of rainfall during the ripening period(august-september)of wine grapes in the northern slope of Tianshan Mountains in Xinjiang from 1961 to 2016.According to the results of previous studies on climatic suitability regionalization of wine grape planting in this region,the characteristics of rainfall and its influence on ripening stage of wine grape in different suitable planting regions were analyzed.The results showed that the spatial distribution of the number of rainfall days,rainfall,consecutive rainy weather,rainfall intensity,and the number of rainfall days of a large number of days during the ripening period of wine grapes on the northern slope of Tianshan Mountains all showed the characteristics of increasing with altitude.In the past 56 years of wine grape ripening stage in the study region,except for the extremely significant decrease in rainfall days with a tendency at rate of-1.16 d/10 a(P≤0.001),and a significant increase in the number of rainfall days of a large amount with heavy rainfall with a tendency at the rate of 0.07 d/10 a(P≤0.05),The change trend of other rainfall climatic factors was not significant.In the most suitable,suitable and sub-suitable for wine grape growing areas in this region,the rainfall is less than 90 mm,the number of rainy days is less than 2 days,the number of consecutive rainy days is less than once,and the number of consecutive rainy days is less than 40 mm during the grape ripening period,there are less than 90 mm of rainfall,less than 25 of rainfall days,less than 2 days of heavy rainfall,less than 1 consecutive rainy weather,less than 40 mm of continuous rainfall during the grape ripening period.It is very beneficial to increase the yield and quality of wine grapes.From August to September,the regions with rainfall i
