生态公益林价值核算研究

论文采用成本法、意愿调查法、森林环境效果评价法及木材需求曲线修正法等方法对井冈山林区生态公益林价值进行核算,并对其结果进行分析。经计算,成本法(社会贴现率以10%计算)、意愿调查法、森林环境效果评价法及木材需求曲线修正法的计算结果比例为0.4592∶0.2185∶1.7106∶1。分析认为,以木材需求曲线修正法得出的每年森林资源价值平均为1302元hm²较为合理可作为区域内生态公益林的补偿值成本法计算的年成本值597.9元hm²可作为生态公益林补偿的最低限值意愿调查法计算的每年支付意愿值284.5元hm²可作为当地受益群众对生态公益林的补偿费用。

A study on ecological forest

In this paper,cost method,contingent value method,forest resource environmental ef-fect evaluation method and timber demand curve amend method were applied to calculate value of ecological forest in Jinggang Mountain region,Jiangxi of China.The results showed that the e-cological forest's value ratio using cost method(discount rate is10%),contingent value method,forest resource environmental effect evaluation method and timber demand curve amend method is0.4592:0.2185:1.7106:1.Analysis revealed that the timber demand curve amend method,whose annual accounting value is1302yuan/hm 2 and can be applied to ecological forest's value compensation,is more reasonable than others;the cost method with an annual accounting value of597.9yuan/hm 2 can be considered as the minimum of the value compensation;and contingent value method with an annual value of284.5yuan/hm 2 can be only used as the amount of the value compensation for those people benefited from the ecological forest.
