Valuation of ecosystem services for Huzhou City, Zhejiang Province from 2001 to 2003 by Remote Sensing data

Abstract

The land covers of Huzhou City (119°14'–120°29'E, 30°22'–31°11'N) that includes five regionalisms of Anji County, Changxing County, Deqing County, Wuxing District and Nanxun District were classified into eight types by using Remote Sensing data, which were forest, grassland, shrub, paddy field, dry land, bare land, water and wetland. The indexes of ecosystem services of each type of land cover were divided six items, such as the producing organic matter, assimilating CO₂, releasing O₂, recycling nutrient matter, holding water, and conserving soil and water. The results showed that the value of ecosystem services for Huzhou City in 2001, 2002, and 2003 was 194.82×10⁸ yuan, 207.68×10⁸ yuan, 173.56×10⁸ yuan, respectively. Anji County of five regionalisms had the best environment conditions among all the districts, which played the most important role in ameliorating the ecological environment for Huzhou City. Environment conditions of Deqing County were at the worst level. The GDP per capita and per unit area of each county (district) was in inverse proportion to the value of ecosystem services per capita and per unit area, which implied that the higher GDP was, the more severe contamination of environment was.
