Evaluation of Ecosystem Service Value in Mountainous Tourism Areas Based on Value Equivalent Factor Methods:A Case Study of Mount Tai in Shandong Province
Changes of land use/cover,which is significant to ecosystem service value,plays an important role in maintaining ecosystem service function.As famous mountain tourism area,safeguarding ecosystem services of Mount Tai is important for the development of tourism.This paper takes the area of Mount Tai as the re-search object.Firstly,different land use/cover types were divided by GIS and remote sensing technology.Secondly,based on the land use/cover data of 2000,2005,2010,2015 and 2020,and due to the improved assessment methods of ecological service value,impacts of land use changes on ecosystem service value in area of Mount Tai in the past 20 years were analyzed.Thirdly,sensitivity of ecosystem service value to coefficient variation was discussed.The results are as follows.① From 2000 to 2020,total area of arable land,forest-land and grassland in the area of Mount Tai accounted for more than 97％,while the area of water and unused land was less than 3％;During the period,area of arable land decreased by 12289.95 square hectometers,and area of forest land and the grassland decreased by 1279.92 square hectometers and 926.1 square hectome-ters respectively,while the water area increased by 232.56 square hectometers.② In the past 20 years,eco-logical service value in the area of Mount Tai increased from 19.67 × 10^8 yuan to 23.12 × 10^8 yuan,with an increase amplitude by 17.56％.③ Sensitivity indexes of ecosystem service value in area of Mount Tai were all below 0.30 in different years,that shows the response of ESV to changes of the indexes were not signifi-cant,so the selected indexes was reasonable and reliable.
