摘要
Abstract
Basing on counted latest frost date and frost time of wine grape frost climate index,the article analyzes the basic characteristic and variation trend of Ningxia wine grape late frost according to everyday minimum air temperature data in 16 meteorological stations in Ningxia from 1961 to 2015 with the methods of statistics and climatological diagnosis.The result shows that,the average latest frost date of wine grape is between middle April till early May in Ningxia,and the boundary line of latest frost is between end April and middle of May at each stations counted according to assurance rate of 90％;the average period of wine grape latest frost in the whole region is 92 days.The average latest frost date tends to be earlier in Ningxia,the interannual variation tendency in 2 districts accords with the whole region;the frost period of wine grape tends to decrease in the whole region;the frost time linear tendency in Yellow River diversion irrigated area is close to the whole area.The average latest frost in the whole area tended to be late from 1960s to 1980s,and earlier after 1990s,the latest frost tends to be earlier significantly since 21st century,especially recent 5 years;comparing with the mean value of 55 years,the light,medium,and heavy frost period tends to be more in 1970s,identical in 1960s and 1980s,and less in 1990s,it decreases significantly since 21st century,especially recent 5 years.The mutation year of Ningxia's latest frost is 1984 in recent 55 years,and 1986 in Yellow River diversion irrigated area,and 1983 in central arid area;the mutation year of frost is 1984.关键词
