- Abstract:
-
Ecosystem service value can be used to measure the status of ecological environment, however there is no unified accounting method, and the calculation results are quite different. This paper aims to compare the differences between evaluation methods and calculation results. Therefore, the equivalent factor assessment method and the functional value assessment method were simultaneously used to calculate the ecosystem service value of the Hangzhou Bay area from 2000 to 2015, and the results were compared and analyzed. The results of equivalent factor evaluation method showed that the ecosystem service value was 77.958 billion yuan and 73.663 billion yuan in 2000 and 2015, respectively, and the results of functional value evaluation method were 78.186 billion yuan and 81.037 billion yuan, respectively. The results show that the outcomes of the two methods are relatively close, but present two opposite trends: rising and falling. In view of this difference, we compare the two calculation methods of ecosystem service value, and learn that the functional value evaluation method is more detailed for the evaluation of smaller spatial scale, which can fully evaluate the output of construction land in eco-cities with ecosystem service value being more balanced in the functional structure and spatial distribution, therefore, it is more suitable for the areas with higher urbanization degree, such as the Hangzhou Bay area.
