贵州省森林生态恢复效益评价研究

Study on Benefit Evaluation of Forest Ecological Restoration in Guizhou Province

文章采用森林生态恢复效益评价模型,对贵州省森林新造林资源的涵养水源、净化空气、释O2固碳和物种多样化等方面的生态恢复效益价值进行评价。研究结果显示,贵州省森林生态恢复效益总价值为47亿元/年。恢复效益价值最高是释O2价值22亿元/年,占46.79%。调节水量价值12亿元/年,占25.52%;净化水质价值5.44亿元/年,占11.57%;提供负离子价值0.0354亿元/年,占0.08%;吸收污染物价值0.38亿元/年,占0.81%;固碳价值6.23亿元/年,占13.25%;物种多样化保护价值0.934亿元/年,占1.99%。结合社会经济发展水平修正后的贵州省森林生态恢复效益的总价值为31亿元/年。

In this study, the evaluation model of forest ecological restoration benefits was used to evaluate the ecolog- ical restoration benefits of conservation water sources, air purification, carbon sequestration by releasing O2 and spe- cies diversity of new forest resources in Guizhou Province. The results showed that the total value of forest ecologi- cal restoration in Guizhou was 4.7 billion Yuan/year. The highest value of recovery was O2 value of 2.2 billion Yuan/year, accounting for 46.79%. Regulated water volume value was 1.2 billion Yuan/year, accounting for 25.52%; purified water quality value was 544 million Yuan/year, accounting for 11.57%; negative ion value was 3.54 million Yuan/year, accounting for 0.08%; pollutant absorption value was 38 million Yuan/year, accounting for 0.81%; carbon sequestration value was 623 million Yuan/year, accounting for 13.25%; species diversity protection value was 93.4 million Yuan/year, accounting for 1.99%. The total value of forest ecological restoration benefit in Guizhou Province was 3.1 billion Yuan/year after the revision combined with the social and economic development level.
