内蒙古生态系统服务价值遥感测量

Measurement of Ecosystem Service Value Based on Remote Sensing——A Case Study in Inner Mongolia,China

生态系统功能是地球生命系统的支持系统,为人类创造赖以生存的生态环境条件,有巨大的直接与间接经济价值。利用遥感技术,通过对生态系统类型、植被覆盖度和净第一性生产力的测量,建立生态系统服务价值遥感定量计算模型,结合前人的研究成果,对内蒙古生态系统服务价值进行定量的计算。

The biosphere of the Earth is essential to human survival and development. The services of ecosystems are critical to the functioning of the Earth＇ s life-support system. They contribute to human welfare both directly and indirecdy. An estimation model for ecological service value based on remote sensing is presented in this paper. The parameters in the model are quantitatively measured using MODIS and other ancillary data, including the land cover types, the vegetation coverage, and the net primary productivity （NPP） of terrestrial ecosystem. A case study is conducted in Inner Mongolia. We encountered most of problems and uncertainties, but it could reflect the special distribution of ecological service value in a way, and could offer the basis of scientific layout for region ecological construction in Inner Mongolia.
