Estimation of Urban Ecosystem Services Value: A Case Study of Chengdu, Southwestern China

Research on the service values of urban ecosystems is a hot topic ecological studies in current era rapid urbanization. To quantitatively estimate ecosystem value Chengdu, China from perspectives natural ecology and social ecology, technologies remote sensing (RS) geographic information system (GIS) are utilized this study to extract land use type RS images Chengdu 2003, 2007, 2013 2018. Subsequently, driver analysis services was performed based socioeconomic data last 16 years. The results indicated that: (1) 2003 2018, utilization changed significantly, with area cultivated lands, forest lands water decreasing remarkably, while construction dramatically increased. (2) (ESV) decreased by 30.92% years, CNY 2.4078 × 1010 1.6632 Based future simulation, ESV further predicted be reduced 1.4261 2033. (3) showed negative correlation total population, urbanization rate per capita GDP region, indicating that studied region inter-coupled development can maintained at high level through rationally regulating structure.
