内蒙古和林格尔县草地生态系统服务功能价值评估

The Service Function Values of Grassland Eco-system of Holingeer County in Inner Mongolia

根据生态系统服务功能的研究成果,结合内蒙古和林格尔县草地生态系统实际情况,参照Constanza等的思路与方法,估算了内蒙古和林格尔县草地生态系统的各项服务功能价值,得出全县草地每年的生态系统服务价值为564.8×106元,其中土壤侵蚀控制价值占82.0%,其他价值占18.0%,说明和林格尔县草地生态系统对减少土壤侵蚀、保持土壤养分有巨大作用.

According to the development of ecosystem service function research and grassland eeosystem＇s actual situation in Holingeer county of Inner Mongolia, each kind of service function value is estimated based on the Constanza＇s method. The results show that the grassland ecosystem service value in Holinger county is ￥564.8× 10^6 ,of which the value of conservation of water and soil account for 82.0%, and others 18.0%. So the grassland ecosystem in Holinger county has huge economic efficiency to reduce the soil erosion and carry out water and soil conservation. The study results can help people understand the grassland ecosystem service functions, and strengthen the grassland ecological environment construction and management.
