评价了新疆草地生态系统的主要功能,重点对不同草地类型的生态系统服务和功能价值进行尝试性的估算.结果显示,新疆草地系统年平均价值为71.32×10^8美元;新疆草地的主体类型提供的服务价值仅占总价值的43.17%,对草地生态系统服务总价值贡献率不高;低平地草甸提供的生态服务价值最高;沼泽和温性草甸草原在草地生态系统中所占的地位很低;草地各类功能价值中,提供给畜牧业生产上的经济功能仅是草地经济服务价值的很小部分.这些结论体现了新疆草地生态系统的特殊性以及开发和保护的潜力.
We analyze the main services function of Xinjang' s grassland ecosystem and puts emphasis on evaluating the value of ecosystem services and function. The results show that the average value of Xinjang's grassland ecosystem is $ 71. 32× 10^8 each year;the value of the main grassland type is only up to 43.17% ;the meadow provides the highest while the swampland and temperate zone grassland have lower value in the whole ecosystem services value;the function of providing goods is a smalle part of the whole grassland ecosystem' s services function. Those results help people have a better understanding of the special features of Xinjang's grassland ecosystem and its potentiality of exploitation and protection.
