Characteristic analysis of ecosystem service value of water system in Taiyuan urban district based on LUCC

Changes in the land use and ecosystem service value of the 600 m buffer zone of Jinyang Lake and the 1000 m riparian zone of the Fenhe River in the Taiyuan urban district in China, were studied using satellite image data collected in June 2006 and June 2013. According to the ecosystem services assessment system based on expert knowledge, the ecosystem service value (ESV) per unit area was determined for various land-use types and the value of the water system and its buffer regions in the Taiyuan urban district were determined. And then the relationship between LUCC (Land Use/Cover Change) and ESV was discussed. The results showed that: the areas of green vegetation and water bodies of Jinyang Lake and its buffer region decreased by 24.96% and 3.22%, respectively, between June 2006 and June 2013, whereas the areas of farmland and built-up land increased by 15.81% and 12.37%, respectively.
