山西地处黄土高原,丘陵和山地占70％以上,常年干旱少雨,水资源较少,且水土流失严重。果树大部分布在干旱丘陵、山地,其中太行山为山西果树的主要分布区,其海拔、气候、土壤等生态条件极有利果树的生长发育。但目前由于缺乏以保水为中心的科学管理 Shanxi is located in the Loess Plateau, hills and mountains account for more than 70%, perennial drought and drought, less water resources, and serious soil erosion. The fruit trees are mostly distributed in arid hills and mountains. The Taihang Mountains are the main distribution areas of Shanxi fruit trees.
