| Abstract: |
| 【Objective】 Making an evaluation on the value of comprehensive service benefits will provide a solid basis for study and practice of eco compensation and Green GDP evaluation in Lantian County.【Method】 The study,using western eonomics as the foundation of theory according to the forestry data of Lantian County,with shadow engineering method of cost evaluation,opportunity cost method and damage/income evaluation method,made an evaluation on comprehensive service benefits of the forest ecosystem in Lantian County. 【Result】 The total forest ecosystem value is about 28 089.53×104 yuan/a,0.485 9×104 yuan/(hm2·a),about 4.3 times more than direct economic value of the forest resources in 2006.【Conclusion】 The value of forest ecosystem service benefits is mainly manifested in conserving soil and water and forest recreation.The compensation policy of ecological benefits to forest should be carried out continuously and the standard of compensation should be improved. |
