【摘要】 针对岩溶区生态系统服务价值研究相对薄弱的现状,以中国三个生态文明试验区之一的贵州省为研究对象,基于研究区2015年ZY-3和GF-1号卫星影像数据,采用修正后的生态系统服务价值系数,估算了贵州省生态系统服务价值,并分析其岩性分异和地域分异特征。结果表明,2015年贵州省各种类型生态系统服务价值总量约4809.1×10~8元,主要为调节服务功能,以灌木、阔叶林为主的森林服务价值量最高。贵州省生态系统服务功能价值区域分异明显,总体上呈现出西北较低,东南部较高的特征,大体趋势上从东南向西北逐渐降低。贵州省岩溶区生态系统服务价值比非岩溶区高767.8×10~8元,但岩溶区单位面积生态系统服务功能价值比非岩溶区低4617元/hm~2。更多还原

【Abstract】 Based on the data of ZY-3 and GF-1 satellite images in 2015, the service value of ecosystem in Guizhou Province, one of the three experimental areas of ecological civilization in China, is estimated by using the modified service value coefficient of ecosystem, and the characteristics of lithologic and regional differentiation are analyzed. It is suggested that in 2015, the total value of ecosystem services of various types in Guizhou Province was about 4809.1×10~8 yuan, mainly for regulating the service function, and the forest service value mainly composed of shrub and broad-leaved forest was the highest. The regional differentiation of ecosystem service value in Guizhou province is obvious, which is generally lower in the northwest and higher in the southeast, with a general trend of decreasing from southeast to northwest. The service value of ecosystem in karst area of Guizhou Province is 767.8×10~8 yuan higher than that in non karst area, but the service value of ecosystem per unit area in karst area is 4617 yuan/hm~2 lower than that in non karst area.更多还原
