摘　　要：采用EM 50土壤水分测定系统,对4种不同整地规格的土壤含水量进行连续监测。以整地成本、土壤平均含水量、造林成活率、林木生长量为指标,综合分析不同整地规格的效果。结果表明,4种整地规格中,2 m×1 m×0.5 m(G2)规格的土壤平均含水量最低,整地成本最高。由于太行山北段土壤干旱瘠薄,造林困难,整地时优先选取0.8 m×0.6 m×0.4 m(G0.8),0.6 m×0.5 m×0.4 m(G0.6)这两种规格。The soil water content of 4 kinds of soil preparation was continuously monitored by adopting EM50 as soil water determining system.The effects of different soil preparation types were analyzed through cost of soil preparation,average water content of soil,afforestation survival rate and growth increment of tree.The results showed that soil water content of 2 m×1 m×0.5 m（G 2）was the lowest,but the cost of soil preparation was the highest.Two types of 0.8 m×0.6 m×0.4 m（G 0.8） and 0.6 m×0.5 m×0.4 m（G 0.6）were preferentially selected because the northern section in Taihang Mountain is barren,cold and drought,and its afforestation is difficult.
