摘　　要：采用EM 50土壤水分测定系统,在晋北太行山区雁门关林场,对造林后采用石块、石块薄膜双层、生态垫3种不同覆盖处理的土壤含水量进行连续监测,以不同覆盖处理成本、造林成活率、苗木生长量、蓄水保墒效果等为指标,对不同覆盖处理综合效果进行秩次综合评价,3种覆盖处理被分为两类,以生态垫覆盖效果最好。Using EM50 soil moisture determination system,the soil moisture contents were continuously determined through 3 kinds of mulching treatments which are stone blocks after forestation,stones and film double-layer mulching,eco-mat mulching.The comprehensive evaluation of rank order on the effects of various mulching treatments was made with costs of various mulching treatments,the afforestation survival rate,seedling increment,moisture conservation effect,etc.as indexes,the three mulching treatments were divided into two types,of which eco-mat had the best effect.
