AB  - Xishuangbanna in the southwestern border of China is located in the upper reaches of the Mekong River between the Indo-China Peninsula and the East Asian continent. It is the largest tropical rain forest and monsoon forest in China. They have an irreplaceable ecological service function and are an important barrier to maintaining the ecological security of the Mekong River transboundary basin of the Lancang River. Based on three sets of remote sensing data (1996, 2003, 2010 and 2016), this study has made an exploration on spatio-temporal changes of Xishuangbanna, and also made an assessment on different ecosystem values of six types of ecosystem in Xishuangbanna based on related theories of ecological economics. Results showed that the values of Xishuangbanna ecosystem services in 1996, 2003, 2010, and 2016 were 70.4014billion yuan, 70.2115 billion yuan, 68.5129 billion yuan and 63.6098 billion yuan, respectively. The total value shows a continuous decreasing trend, reflecting the continuous decline in the ability of the Xishuangbanna ecosystem to provide services to humans. If divided by ecosystem types, forest and rubber were two types that have the greatest proportion of service values. In the perspective of service types, soil formation and protection account for the largest proportion, followed by gas regulation and biodiversity protection. Studying Xishuangbanna’s ecosystem service values is helpful to explore the sustainable development of resources and economy.Highlight This paper used coefficient of sensitivity to determine the dependence of ESV on the change of ecosystem value coefficient over time.The total amount of ESV shows a continuous downward trend, indicating that the ecological environment of Xishuangbanna is still severe.The temporal-spatial change of ESV was analyzed for two decades.
