- 摘要:
- 生态系统服务功能是生态学、生态经济学研究的热点问题，对于促进生态系统可持续管理具有重要作用。昌都地区属于青藏高原的一块典型高原生态脆弱区，对其进行生态系统价值评估有利于其生态和经济的可持续发展。运用谢高地等人制定的中国陆地生态系统的价值评估方法，对昌都地区的生态系统服务功能价值进行评估。结果表明：该区各类生态系统的总价值为105435.12×106元，是当年GDP的37倍。各生态系统类型中林地价值最高，其次是草地。直接利用价值（包括食物生产、原材料生产、娱乐文化功能）每年约为13567.38×106元，间接利用价值（包括气体调节、气候调节、土壤形成与保护等）约为59412.5×106元，间接利用价值远远大于直接利用价值，说明间接利用价值对人类的贡献和作用与提供产品本身一样重要。
- Abstract:
- The study of ecosystem services and their valuation is a hot-pot issue in ecology, which plays an important role in boosting sustainable ecosystem management.Changdu is a typical ecological frangible district in tableland of Tibet.Ecosystem valuation is in favor of the strategy of sustainable development of economy and environment in the region.This article valuates the ecosystem services in Changdu district by using the methods of valuation of land ecosystem in China which established by Xie Gaodi et al.The results indicated that ecosystem services value of Changdu is some 105 435.12×106 Yuan annually, which is 37 times than the GDP in the same year of the region.The woodland is the most valuable type in ecosystem and grassland in the next place.The direct values including food and raw materials manufacture along with tourism are 13 567.38×106 Yuan annually, the indirect values in terms of climates adjusting, pneumatic control and soil formation and protect are 59 412.5×106 Yuan annually, the conclusion which indirect values higher than direct values indicates that indirect values have the same contribution and effect with the manufacture itself.
