利用陕西96个气象站1981—2010年气象资料和地理信息数据，采用GIS技术对核桃种植进行气候适宜性区划。通过对陕西核桃生长的生态气候适宜性和陕西气候特点分析，选取年平均气温、年降水量、年日照时数、极端最低气温多年平均、日平均气温≥38℃日数5个因子作为陕西核桃种植气候适宜性区划指标，建立区划因子的小网格推算模型，在GIS技术的支持下完成其空间化，采用模糊综合评判的方法得到陕西核桃精细化气候适宜性区划图，并进行分区评述。研究结果表明：适宜区主要分布在北起陕北北部的安塞、子长、清涧、吴堡一线，南至陕南汉江河谷，除秦岭、陇山、黄龙山的深山外，陕北沟壑区、渭北塬区、关中平原和秦岭的浅山丘陵地区；渭北旱塬以北和秦岭北麓高海拔适宜区，应选种抗霜冻核桃品种，在避风向阳、半阳坡的坡地栽植；陕南秦巴山区适宜区应选种抗湿性好、抗病性强的核桃品种。

Based on the meteorological data of 96 weather stations from 1981 to 2010 and geographical information in Shaanxi province ,GIS technology was employed for climatic divisions of walnut to provide scientific basis for sustain-able development .Through the analyses of climatic suitability and characteristics in Shaanxi ,five indexes including an-nual mean temperature ,annual mean precipitation ,annual mean sunshine hours ,extremely minimum temperature ,and the day numbers of daily maximum temperature ≥38℃ ,were selected as the climatic regionalization criteria .Subse-quently ,small grid reckon model was established to calculate the spatial distributions of each regionalization index values using GIS technology .Comprehensive evaluation method was further used to assess the distribution graph of the climati-cally suitable planting areas for walnut . The results indicated that the suitable regions were distributed in northern Shaanxi from the area along Ansai ,Zichang ,Qingjian ,and Wubu to the area along Hanjiang river;and in southern Shaanxi ,these regions included the Loess Hilly and Gully Region of Northern Shaanxi ,the northern bank of Weihe river , Central Shaanxi Plain ,and the valley and shallow mountain areas of Qinling ,excluding the remote mountain areas of Qinling ,Longshan ,and Huanglong .The suitable region of the northern Weibei Plateau and the high altitude areas of North Slope of Qinling Mountains should select anti-frost walnut varieties planting in sheltered sunny and semi-sunny slope region;And that of Bashan Mountains may choose walnut varieties with good moisture and strong disease resistance .
