甘肃葡萄气候区划与栽培建议

Climatic Regionalization and Viticulture Suggestion of Grape in Gansu Province

选用无霜期和活动积温作为甘肃葡萄气候区划的热量指标,生长季干燥度为水分指标,埋土防寒线为辅助指标,以甘肃省80个气象站点1981—2010年30年气象数据和全省3"(90 m)分辨率数字高程模型(DEM)为基础数据,建立了全省无霜期、活动积温的多元逐步回归模型,并将全省分为3个区域分别建立了干燥度多元逐步回归模型,对各指标空间回归模型进行残差插值校正,在此基础上绘制了甘肃省葡萄气候区划图,将甘肃省欧亚种葡萄适宜栽培区划分为4区、11亚区,将山葡萄种植区划分为可种植区和适宜种植区,并根据不同区域特点对各区葡萄栽培提出了意见和建议。

This study considered frost-free period and active accumulated temperature as the heat index of the climatic regionalization of grape in Gansu Province,and the dryness index in the grape growth season as the moisture index,buried line as an auxiliary index,to establish the multivariate stepwise regression model of the frost-free period and active accumulated temperature on the basic of the meteorological data of 80 stations during the past 30 years（from 1981 to 2010）and the digital elevation model（DEM）with the resolution of 3＂（90 meter） in Gansu Province,and divided the province into 3 zones for each one we established the multivariate stepwise regression model of dryness index,made residual interpolation correction for each spatial regression models with different index,the climatic regionalization map of grape in Gansu Province was produced on this basis,the suitable cultivation area for Eurasian grape in Gansu Province was divided into 4 districts and 11 sub-districts. The mountain grape cultivation area was divided into ordinary cultivation area and suitable cultivation area,opinions and suggestions for grape cultivation in different regions were also put forward according to the different regional characteristics.
