The model application of ecosystem service valuation based on TM remote sensing in Yongding River
基于TM遥感技术的永定河生态系统服务价值评估模型及应用

Dynamic evaluation of Yongding river ecosystem services make a certain improvement of traditional static evaluation in long period work, mass amount of work, high price, low precision, and so on. By correlating TM remote sensing and equivalent weight factor, it is with ecosystem services value unit area of Yongding River ecosystem that established multi regression model could calculate based on a mere remote sensing data directly and precisely. What is more, the model is used to calculate the land use area corresponding to different ecosystem services for the propose of Yongding river restoration quantificationally.
