Natural landscape is made up of natural environment, substances and scenes, which can provide people many kinds of services and benefits, such as enjoying the scenery and participating recreational activities. However, these benefits were not included in the cost-benefit analysis when people developed natural resources. People's underestimate and ignorance of natural landscape's value have led so many irreversible environmental problems. If we can evaluate the value and analyze the value's change over years, the decisions related with exploitation of natural resources can be scientific supported. This research uses Xiangshan Park as a study case to evaluate the natural landscape value, which is supposed to be the sum of use value and non use value. Choosing individual travel cost method and contingent valuation method to evaluate use value and non use value, respectively. The use value of Xiangshan Park is 1925 million RMB while non use value is 346 million RMB in 2012.This study then deeply analyzes the value change between 1992 and 2012. We discover that the landscape value is 17.5 million RMB in 1992 and 2271 million RMB in 2012, which means the value increases almost 130 times with a growth rate of 113 million RMB per year. When exploring the reasons for these changes, we find out that visitor's number is double, people are spending more money visiting Xiangshan Park than before, and they are willing to pay more money to protect the environment and reserve the natural resources. As the environment pollutions are happening every day, people are anxious for a healthy life, so we can predict that natural landscape value and demand of Xiangshan Park will continue to rise. The scenic spot authority should get a full understanding of Xiangshan Park's value, finding practical ways to solve the environmental problems when developing tourism.
