摘　　要：研究达赉湖自然保护区生态系统服务价值的变化。采用市场价值法、影子工程法、机会成本法、司法价格法等方法评价了达赉湖自然保护区1999年和2007年的主要生态系统服务价值。1999年保护区生态系统服务价值达353.28亿元。1999—2007年保护区生态系统服务价值下降了28.66%,其中调蓄水量价值、物质生产价值、生物多样性价值下降较大。达赉湖地区气候变化的暖干化趋势和人类活动影响造成的湖面萎缩、草地退化是造成保护区生态系统服务价值下降的主要原因。Analysis on the ecosystem service value change in Dalai Lake Natural Protection Area. The ecosys- tem service value of Dalai Lake Natural Protection Area in the year of 1999 and 2007 were analyzed using mar- ket value method, shadow engineering method, opportunity cost method, wildlife judicial price method and etc. The ecosystem service value of Dalai Lake Natural Protection Area was 353.28 x 108 Yuan in the year 1999. The ecosystem service value decreased by 28.66% from the year 1999 to 2007. In the changed value of each ecosystem service, the value of controlling water, material production and biodiversity had sharply de- clined. The reason of ecosystem service value decreasing in Dalai Lake Natural Protection Area was due to re- duced water area and grassland degradation caused by climate change and human activity.
