小黑山自然保护区森林生态系统服务功能及价值评估

以小黑山自然保护区的森林生态系统为研究对象,采用影子工程法、机会成本法、市场价值法等研究方法,对其生态系统服务功能的直接价值和间接价值进行了评估.结果表明,小黑山自然保护区的生态系统服务功能价值达10.52×108元/a,其中直接价值为5 406.89×104元/a,仅占服务功能总价值的5.14%,而间接价值高达99 825.04×104元/a,两者之比为1∶18.46.间接价值中大小顺序依次为:涵养水源水土保持维持生物多样性固碳释氧净化空气科研文化.小黑山自然保护区对维持当地社会经济可持续发展具有举足轻重的作用.

Evaluation on Forest Ecosystem Service Function and Values of Xiaoheishan Nature Reserve

Taking forest ecosystem of Xiaoheishan nature reserve as an objective,this paper adopted shadow engineering method,opportunity cost method,market value method and other methods to evaluate the direct and indirect ecological service values.The results showed that ecosystem service value of Xiaoheishan nature reserve amounted to 10.52 ×108 yuan/a,in which direct value was merely 5406.89 ×104 yuan/a,accounting for 5.14% of total service functional value,while indirect value was high to 99825.04×104 yuan/a,the ratio of the direct to indirect value was 1∶18.46.The order of indirect value of ecosystem service from big to small was as followed： water conservation erosion control maintaining biodiversity carbon fixation and oxygen release purifying air scientific research and culture.In conclusion,Xiaoheishan nature reserve played a significant role in maintaining sustainable development of local economy.
