摘　　要：榆林是元宝枫自然分布区之一,但各县区的地理环境、气候条件不同。本文采用无霜期、1月份平均最低气温、大于10℃活动积温作为元宝枫种植区划的主要指标,将榆林各县区划分为元宝枫可种植区和不可种植区,在此基础上,参考各县区的降水量和地理环境特征进一步区划出了适宜种植区和次适宜种植区。研究结果对榆林沙区大面积栽培元宝枫提供了重要理论依据和生产指导。Yulin is one of the natural distribution areas of Acer truncatum.However,the geographical and climatic conditions vary across its counties and districts.In this paper,the frost-free period,average minimum temperature in January,and active accumulated temperature above 10°C are adopted as the main indicators for delineating the planting regions of Acer truncatum.Based on these indicators,the counties and districts of Yulin are divided into suitable and unsuitable planting areas for Acer truncatum.Furthermore,with consideration of precipitation and geographical features in each county and district,the suitable planting areas are further subdivided into optimal and secondary optimal planting regions.The research findings provide important theoretical support and production guidance for large-scale cultivation of Acer truncatum in the sandy areas of Yulin.
