Abstract: The results of quantitative analysis on the amount of tourist, service-environment capacity, eco-environment capacity, and their relations in Five-finger Mountain eco tourism resort indicate that the amount of tourist in common situation and in its extreme was 1918 and 2301 visitor-hour per day, and the service-environment capacity and eco-environment capacity were 6000 and 2400 visitor-hour per day,respectively.The eco-environment capacity was smaller than its service environment capacity,and would become the first limiting factor to the increase of tourist amount,which was mainly due to the ecological fragility of resort,the lower resistance of biological communities to the disturbance,and the slower speed of ecosystem restoration after its being destroyed.
