Study On The Ecosystem Services Value In Response To Land Use Change In Zhangzhou

This study based on the land-use data which was interpreted from TM(1985) and ASTER(2004) remote sensing images in Zhangzhou city, estimated ecosystem service value by quantitative evaluation model which was modified by climatic productivity obtaining from 731 meteorological stations distributed in the whole country. The results of analysis and prediction showed as follows: (1)There were 356.7 billion yuan(1985) and 354.6 billion yuan(2005) in whole city, and ecosystem service value was decreased in Yunxiao, Changtai, Zhaoan, Zhangpu, Huaan counties and Urban district, which was increased in Nanjing, Pinghe, Dongshan counties and Longhai city; (2) Ecosystem service value barycenter migrated 14659 meters from south to west by 6.7 degrees in whole city and had different extent migration in every county; (3)There were gradually increased and increased-jumped trends respectively for inland counties and river-seaside counties’ ecosystem service average value by area with the distance increased from ecosystem service value barycenter, and there were gradually increased trend and a jump between 1km to 2km for every county’s ecosystem service average value by area with the distance increased from building barycenter; (4)The ecosystem service value would have a different extent change in every county and 360.26 billion yuan in whole city for 2023. At last, this study gave some land-use countermeasures to improve ecosystem service value.
