摘要
以宁波天童天然林为例,探讨了将天然林碳汇纳入碳汇贸易的方法和途径,采用条件价值评估法(CVM)估算了天童天然林碳汇价值,并探讨了天然林碳汇贸易的可行性。结果表明:(1)与人工林碳汇相比,天然林碳汇在数量、生态功能和保育价值方面具优势,将天然林碳汇纳入碳汇贸易,是对现有人工林碳汇贸易的有益补充;(2)公众对碳汇贸易普遍持支持和偏好态度,但对碳汇概念认知程度低、对相关政策态度谨慎;(3)据CVM法评估得到天童天然林年均贸易价值合理值约1379万元/a,合2.06万元/t,高于人工林碳汇价格,反映公众对天然林整体生态功能和保护价值的较高支付意愿;(4)影响天然林碳汇价值因素为个人收入、概念了解度、政策支持度和责任的定位;(5)公众对天然林碳汇贸易高度关注、对保护天然林富有热情,所以天然林碳汇进行贸易具有社会基础和可行性。
Taking Tiantong Forest in Ningbo as an example,methods that integrated natural forest into carbon trade market by estimating its carbon sinks and politically feasibility via contingent valuation method（CVM） were discussed.Results indicated that natural forest which has advantages over planted forest in terms of quantity,ecological function and conservation value is a favorable supplement to bring natural forest into current carbon trade.The public supports and prefers natural forest while has limited knowledge of carbon sinks and conservative attitude toward relative policy.Via CVM,carbon sinks of Tiantong Forest is estimated as 13.79 million RMB,that is 20,600 RMB per ton which is higher than that of planted forest reflecting a public preference.Factors affecting WTP include personal income,understanding of related concept,support to the possible policies and awareness self-responsibility.Public awareness and support is the foundation to establish carbon trade of natural forest.
