| 摘 要： | 荒漠生态系统是中国西北地区的代表性生态系统,具有不同于其他生态系统的独特结构和功能.开展荒漠生态系统服务价值评估,对干旱区的生态恢复与重建以及区域环境保护具有重要意义,有助于促进干旱区的可持续发展.把荒漠生态系统服务划分为防风固沙、土壤保育、固碳释氧、水资源调控、生物多样性保育、旅游文化等6类.在此基础上回顾与评述了相关研究,简要概括了已有研究中存在的主要问题,最后建议加强荒漠生态系统提供的独特服务的价值评估和针对特定地区开展小区域的荒漠生态系统服务价值评估等方面的研究,以及科学选取与调整价格参数.

| Abstract: | Desert ecosystem is a representative ecosystem type in Northwest China, and it has unique structure and functions which are different from those of other ecosystems. It is meaningful to valuate desert ecosystem services for ecological restoration and rebuilding, regional environment protection, and eventually sustainable development in arid lands. This paper classifies desert ecosystem services into six types, i.e. wind break and sand fixation, soil conservation, water resource regulation, carbon fixation and oxygen release, biodiversity conservation, and tourism and culture. Based on the classification, this paper reviews literatures about the valuation of desert ecosystem services, and points out main problems existing in current literatures. Finally, several suggestions for further research are put forward, including enhancing research on valuation of unique services that desert ecosystem provides and on valuation of desert ecosystem services according to specific conditions in small regions, and reasonable selection and adjustment of price coefficients for desert ecosystem service values valuation. |
