摘要
五台山地区草地资源丰富,草地生态系统不仅对当地提供重要的生态、生活功能,而且对整个华北地区生态系统的格局和稳定都起到重要作用。文中以五台山地区为研究对象,对其草地生态系统服务功能进行价值估算。结果表明:五台山地区草地生态系统服务总价值为114.62亿元,其中供给功能价值为34.64亿元(占30.22%),支持功能价值为55.86亿元(占48.73%),调节功能价值为20.26亿元(占17.68%),文化服务功能价值为3.86亿元(占3.37%),草地生态系统单位面积价值量为4.33元/(m2·a);按价值量大小各服务功能类型依次为:提供食物产品>固碳释氧>营养物质保持>涵养水源>生物多样性保护>休憩娱乐>废弃物降解>环境净化>土壤保持。该研究结果对于人们加强对五台山地区草地生态系统重要性的认识,为本区制定合理的区域生态保护、资源开发对策有重要意义。
Grassland ecosystem produces an array of goods and services for mankind,which plays a key role in maintaining the structure,functions and ecological processes of natural ecosystems. The grassland ecosystem services of Wutai Mountains area were evaluated. The results showed that the total economic value was 11. 462 billion Yuan,among which the value of provisioning service was 3. 464 billion Yuan,the value of supporting service was 5. 586 billion Yuan,the value of regulating service was 2. 026 billion Yuan,the value of cultural service was 0. 386 billion Yuan,accounting for 30. 22%,48. 73%,17. 68% and 3. 37% of the total value respectively. At the same time,the grassland ecosystem economic value per unit area was 4. 33 Yuan. Based on the different service types,the services could be arranged from the maximum to the minimum value as： product offers,carbon sequestration and oxygen release,nutrient cycling,water conservation,biodiversity protection,eco- tourism,waste degradation,environmental purification,soil conservation. The research results were beneficial to strengthen the recognition of the importance of grassland ecosystem of Wutai Mountains area,make reasonable regional ecological protection method and grassland resource utilization.
