The differences of the regional ecosystem service value (ESV) in time and space are an important symbol to reflect the health of the ecosystem. Based on the theory and method of ESV, take Fengnan district as an example, and the paper analyzes the change of ESV from 1998 to 2009, evaluates the temporal and spatial differences among the 15 towns, and compares the relationship between ESV change and economic development. The results are the ESV of Fengnan is in a declining trend during the period. According to the ESV variation of the towns, Fengnan district is divided into four zones: value-added area, low consumption area, middle consumption area, high consumption area. The economic development has a great negative impact to the ESV in Fengnan. In order to protect the coordinated development of economy and ecosystem, some proper measures should be carried out, such as transforming the economic development mode, using land resources intensively, protecting and restoring the ecological areas.
