摘要:
 灌木围障是预防林木兔害的有效方法。为了评价灌木围障方法的经济性,研究了灌木围障的投入产出比和投资收益率。结果显示,灌木围障成本主要是用工支出,总效益取决于处理区和对照区林木的保存率、单价和定植株数。试验期内,桥北林区2种处理的净增益分别为(2 806.25±37.84)元·hm-2和(490.33±3.47)元·hm-2,旬邑为(711.84±5.45)元·hm-2和(388.25±3.30)元·hm-2。桥北灌木篱笆投资回收期2 a,投入产出比1∶5.98;灌木围墙投资回收期为3 a,投入产出比1:2.50。旬邑2种处理的回收期均为4 a,投入产出比为1∶2.05和1∶1.41。证明灌木围障,尤其是灌木篱笆处理是一种经济有效的林木兔害预防方法。
Abstract:
 Barriers established with shrub branches around newly planted seedlings are effective measures to prevent young seedlings from hare damages.The seedlings were enclosed by the shrub branches with a shape of squared fence (SF) and tetrahedronal walls (TW).In order to evaluate the economic efficiency of these measures,input and output ratio and the rate of return on investment were analyzed.The costs of the two measures were mainly from the labors used.Total benefits were determined by preserving rate,unit price,and the number of the seedlings. During the trial period,the net gain of the two methods in Qiaobei were (2 806.25±37.84)yuan·hm-2 and (490.33±3.47)yuan·hm-2,respectively; in Xunyi were(711.84±5.45)yuan·hm-2 and(388.25±3.30)yuan·hm-2.In Qiaobei,the payback period of the SF was 2 years with a ratio of input to output 1∶5.98,3 years for TW with a ratio of input to output 1∶5.98.In Xunyi the payback periods of the two methods both were 4 years,and the ratios of input to output were 1∶2.05,and 1∶1.41,respectively.The data indicated that two methods,especially SF,were cost-effective to prevent forest damage from hares.
