利用TCM法和CBA法对日本朝日林进行经济效益评价

The Economic Benefits Evaluation for Asahi Forest of Japan by TCM and CBA approaches

从环境保护的角度出发,将旅行费用法TCM和费用效益法CBA结合起来,把TCM方法评价出的森林游憩效益纳入了森林的经济收益中,再用CBA法对日本朝日林进行了经济效益评价。评价结果,1997～2001年的游憩效益分别为1079、1084、1211、950、930万日元,B/C比值分别为1 39、1 48、1 29、1 15、1 19,平均值为1 3。这种考虑了森林的公益效益的经济效益评价方法,符合森林的可持续经营理论,比较合理地反映了森林的经济效益,为经营者的合理决策提供了参考。
