| 摘 要： | 以农牧交错带的典型县——内蒙古武川县为例,计算出武川县生态系统水土保持、涵养水源、气候调节和维持营养物质循环等服务的总价值为6179638.49万元,是2000年该县国民生产总值的151倍,而其中草地发挥了巨大的作用。通过研究该县的生态系统服务功能和价值,试图为农牧交错带地区的生态建设与农业结构调整的战略问题提供理论上的支持。

| Abstract: | The Wuchuan county of Inner Mongolia, situated in the ecotone between agriculture and pasture in North China,was taken as the study example. We have calculated the value of its ecosystem service, which mainly composes of conserving soil water, keeping water, regulating climate and maintaining nutriment circling, etc. The gross value of the ecosystem service is 61.796 billion Yuan(RMB),which is 151 times of the GDP of this county in 2000. Among the ecosystem service value the grassland has contributed much to. Based on the research above we try to provide some theoretical support for strategic issues such as ecological construction and agricultural structure adjustment for this area. |
