摘　　要：选择3种不同立地质量的土地:Ⅰ类地(坡底旱田)、Ⅱ类地(中下坡旱田)、Ⅲ类地(中坡荒地),进行黄甜竹造林试验,并分析不同立地质量经营黄甜竹的经济效益。结果表明:黄甜竹在不同立地质量土地上生长效果不同,笋、材产量从大到小的排序为Ⅰ类地>Ⅱ类地>Ⅲ类地,Ⅰ类地上的笋产量和竹材产量分别是Ⅲ类地产量的1.38倍和1.93倍;从经营黄甜竹的经济效益上看,通常在造林后5年内可全部收回前期的投资成本,造林后第8年不包括已建成的竹林价值,可获利6 079元/667 m2,在造林后的8年期间每投资1元平均每年可产生0.3元的直接经济效益。可见,生产上黄甜竹宜种植在山坡中下部土壤较肥沃的土地上,经营黄甜竹经济效益可观。Three types of sites with different conditions are selected for the Acidosasa edulis afforestation experiment,i.e.,Site TypeⅠ(dry farmland at the foot of slope),Site TypeⅡ(dry farmland at the lower part of slope)and Site TypeⅢ(bare land at the middle part of slope),and the economic benefits on the 3 types of sites are analyzed.The results show that A.edulis forests present the different growth effect on the sites with different conditions,and the yield of shoots and bamboo timber is ordered as Site TypeⅠ>Site TypeⅡ>Site TypeⅢ.The yield of shoots and bamboo timber on Site TypeⅠare 1.38 and 1.93 times of the yields on Site TypeⅢrespectively.For the economic benefits of A.edulis forest management,the initial investment can return within 5 years after the afforestation,and can produce the economic benefits of the forest at the 8th year can reach 6 079 RMB/667 m2 except the value of forest itself.In the eight years after afforestation,an average economic benefit of 0.3 yuan per year can be directly generated for every dollar invested.It could be seen that the A.edulis forest should be established on the fertile land in the middle and lower parts of the hillside,which can produce considerable economic benefits.
