摘要
材用毛竹林上、中、下不同坡位之间的产量、产值、采运用工量均差异显著。以400 m2的样地为单位,一次采伐的竹材的重量分别为836.37 kg、1112.85 kg、1 354.12 kg,竹材产值分别为556.87元、766.43元、939.22元,采运每担竹材的用工系数分别为0.096工、0.050工、0.028工;钩梢的毛料重量分别为300 kg、160 kg、350 kg,产值分别为120元、64元、140元,每担毛料的用工系数分别为0.21工、0.18工、0.08工。支付采运等工资后,经营效益分别为-100.31元、294.66元、622.47元,平均270.45元,差异显著并且总体效益不高。事实上已经有部分上坡位的毛竹林因为没有经营效益而开始抛荒了。毛竹林的作用定位及经营模式,应该根据社会的发展变化情况,及时作出调整。
The annual yield,output value and work labor cost of harvesting bamboo were significantly different between slope positions,i. e. upper,middle and lower slope. In a plot of400 m2,on the upper,middle and lower slope,the weight of the harvested bamboo per year was836. 37 kg,1112. 85 kg and 1354. 12 kg respectively,the annual output value was 556. 87 Yuan,766. 43 Yuan and 939. 22 Yuan respectively,and the coefficient of work labor for harvesting each picul of bamboo was 0. 096,0. 050 and 0. 028 respectively. The weight of pruned bamboo tips was respectively 300 kg,160 kg,and 350 kg,achieving a value of 120 Yuan,64 Yuan and 140 Yuan respectively,each picul of pruned bamboo tips needed 0. 21,0. 18 and 0. 08 labor. The annual harvesting benefit was- 100. 31 Yuan,294. 66 Yuan,and622. 47 Yuan respectively after the payment of cutting and transportation,the average is 270. 45 Yuan. The benefits were significantly different between locations,being low on a whole. In fact,some uphill bamboo forests has been abandoned due to little economic benefit. The function and management model of bamboo forests need to be adjusted promptly to adapt to social development.
