摘　　要：荒漠生态系统是我国西北地区的代表性生态系统类型，具有独特的结构和功能。我国荒漠生态系统面积约为165万km2。荒漠生态系统功能主要体现在防风固沙、土壤保育、水资源调节、固碳、生物多样性保育、景观游憩、沙尘生物地球化学循环。本文初步构建了一个较为系统的荒漠生态系统功能与服务评估体系，并给出了各类功能与服务可行的评估方法与模型，为定量评估荒漠生态系统功能与核算其服务价值奠定基础。进一步研究需应用与完善该评估体系与相应的评估方法，从全国尺度上全面定量评估整个荒漠生态系统的功能与服务。Desert ecosystem is the representative ecosystem type in northwestern China, which covers around 1.65 x 106 km2 in this country. Desert ecosystem has its unique structures and functions, for example, its functions mainly include wind-breaking and sand fixation, soil conservation, water resource regulation, carbon sequestration, biodiversity conservation, landscape recreation, and biogeochemical recycling of sand. Thus, this paper proposed a preliminary framework for assessing the functions and services of desert ecosystem, and it suggested feasible methods and models for assessing each function and service quantitatively. Thus further research could focus on improvement and application of the proposed assessment framework and methods, in order to quantitatively assess the functions and services of desert ecosystem at the national scale.
