2001-2003年浙江省湖州市生态系统服务功能价值遥感测量(英文)
Valuation of ecosystem services for Huzhou City, Zhejiang Province from 2001 to 2003 by Remote Sensing data
【摘要】 研究区选择在浙江省湖州市,该市分为德清县、长兴县、安吉县、南浔区和吴兴区五个行政区。利用TM 遥感影像将区域土地利用类型解译为林地、草地、灌丛、水田、旱地、裸地、水域及湿地八类;每类生态系统服务功能又分为生产有机物质、固定和吸收CO2、释放O2、营养物质循环、涵养水源和水土保持六项指标;结合气候数据、统计数据分别测得每项生态系统服务功能价值。结果表明:2001-2003 年湖州市生态系统服务功能价值分别为:194.82、207.68、173.56 亿元;其中安吉县的环境质量状况相对最好,环境容纳能力与自净能力明显要高于其它县(区),因此安吉县对湖州全市生态环境的改善贡献最大。德清县的环境容纳量与自净能力最弱。市辖区及长兴县居中。各县(区)人均及单位面积生产的GDP与单位人口及单位面积分配的生态系统服务功能价值成反比关系,GDP 越高所对应的环境污染也相对较大。表1 图11参12。
【Abstract】 The land covers of Huzhou City (119o14’–120o29’E, 30o22’–31o11’N) that includes five regionalisms of Anji County, Changx- ing 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 propor- tion 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.
