摘　　要：利用已有数据和补充调查数据,试图对西部地区荒漠生态系统进行综合性价值评估,生态系统服务功能价值的货币表示为537.24亿元/a。结果表明,荒漠生态系统每年为人类提供的各种服务的总价值远远大于人们的想象,人们利用的物质产品仅仅是其生态系统服务功能中很小的一部分。We try to do an integrated assessment of desert ecosystem conditions based on theory of ecosystem functions in western China. The result of this assessment is that total value of desert ecosystem service functions in western China is ￥ 53.72 billion every year. The conclusion is that total value of desert ecosystem service is much more than what people can imagine. The physical product that is used in economic accounting is only a little part of ecosystem service functions.
