摘　　要：分析了BFW490型背负式挖坑机在福建省三明市梅列区陈大镇林场挖坑造林的使用效果。结果表明:利用挖坑机造林能够大幅度提高工作效率,当挖坑直径为200mm(以下简称J200)和300mm(以下简称J300)时的工效分别是人工挖坑处理(以下简称CKR)的5.40倍和4.78倍。每667m2(亩)植树造林单挖坑环节J200J、300处理比CKR分别节省1.38和1.36工日;投入成本J200J、300仅为CKR的40.4%和44.4%J,200J、300可以减少投入成本55.75元和52.01元。不同处理造林10年生生长量存在差异,挖坑采用J200J、300处理与CKR处理相比平均胸径分别提高了2.4%和4.8%;平均树高分别提高了3.8%和1.3%;蓄积量都提高了12.9%。在闽西北山地使用挖坑机造林是一条切实可行的造林新途径。The analysis is made of the effect of using BFW490 backpack digger in the pit digging and tree planting operation in the forest farm in Chenda County, Meilie District, Sanming City of Fujian. The result shows that afforestation using a digger can improve working efficiency considerably, when the pit diameter is 200 mm （hereinafter referred to as J200 ） or 300mm （hereinafter referred to as J300）,the working efficiency is 5.40 and 4.78 times that of the digging operation manually （here- inafter referred to as CKR）respectively. As for an afforestation area of 667m^2 （Mu）, the digging chain alone for J200 and J300 can save 1.38 and 1.36 work days respectively than CKR; the input cost of J200 and J300 is only 40.4% and 44.4% that of CKR, with input cost of J200 and J300 reduced by 55.75 yuan and 52.01 yuan respectively. The increment of the affroesta- tion over the 10 years varies with different treatment methods. The diameter at the breast height of J200 and J300 using ma- chines for pit digging has improved by 2.4% and 4.8% respectively, compared with that of CKR, the averaged tree height up by 3.8% and 1.3% respectively and volume up by 12.9% and 12.9% respectively. It is a feasible way to plant trees using a digger in the northwest region of Fujian.
