摘　　要：根据陇南1980～2014年气候资料,以≥10℃的积温、年平均降雨量、空气相对湿度、年日照时数等4个气候因子作为区划指标,采用MR-GIS(即多元回归GIS)模型进行油橄榄气候适宜性研究与分析,得出其气候种植区划:最适宜区主要分布在白龙江、白水江沿岸海拔1 300 m以下河谷及半山区;适宜区主要分布在成县、康县交界处的西汉水和徽县、两当县嘉陵江流域的河谷浅山地带;次适宜区主要分布在礼县、西和南部西汉水河谷区1 300 m以下浅山地带;不适宜区主要分布在陇南各县区海拔1 600 m以上中高山地区。研究结果与陇南市油橄榄实际种植分布区域基本相符,可为研究区油橄榄种植布局提供依据。According to the climate data of Longnan from 1980 to 2014,taking≥10℃accumulated temperature,annual average rainfall,relative humidity of air and annual sunshine hours as the zoning indexes,we used MR-GIS model to study and analyze the climate suitability of olive,and obtained the climatic planting area.The most suitable areas are mainly distributed in the valley and semi-mountainous area below an altitude of 1 300 meters along the Bailong River.The more suitable areas are mainly distributed in the valley and low mountain zone along Jialing River in Hui County and Liangdang County,and the Xihan River at the junction of the Cheng County and Kang County.The suitable areas are mainly distributed in the low mountain zone below 1 300 meters along the Xihan River within Li County and the southern of Xihan River.The unsuitable areas are mainly distributed in the mountain area above sea level more than 1 600 meters in Longnan County.The results are basically consistent with the actual planting area of olive trees in Longnan,which can provide the basis for the olive planting arrangement in the study area.
