摘要: 为探讨山区公路沿线土地利用变化对生态系统服务价值(ecosystem service value, ESV)的影响,以贵州省麻江县309省道为例,基于1992年、2002年、2012年和2032年土地利用数据和中国陆地生态系统服务单位面积ESV系数,对309省道沿线土地利用变化所引起的ESV变化进行估算。结果表明:①研究期间,耕地和草地持续减少,建设用地不断增加,而不同时期的林地、水域和未利用地或增或减。②1992—2032年间,除情景B外,情景A和C的ESV均不断增加。各地类的ESV变化趋势与各地类面积变化一致。除情景B外,情景A和C的各种ESV均不断增加。越靠近公路的缓冲区(距公路0~500 m区域),ESV变化越剧烈,不同时期各缓冲区ESV变化存在差异。③快速经济发展、退耕还林政策、地形限制等是影响公路沿线ESV变化的主要因素。

Abstract: In order to discuss the effects of land use change along the road in mountains region on the ecosystem service value, we took provincial road 309 in Majiang county in Guizhou Province as an example, and analyzed the change of ecosystem service value along the road resulting from land use change based on land use data 1992, 2002, 2012 and 2032 and ecosystem service value coefficient per unit area in China. The results showed that: ① farmland and grassland were consistently decreasing, construction land would keep increasing, while forest land, water body and unused land underwent a positive or negative change during the study period. ② Ecosystem services value for scenario A and C increased except for scenario B. The variation trend of each ecosystem services value was in accordance with the change trend of each land use type. Each category of ecosystem services value continued to increase for scenario A and C except for scenario B. The change rate of ecosystem service value in 0-500 m buffer was bigger than that in the other buffers. In addition, there were differences between different periods for the change of ecosystem service value in four buffers. ③ Rapid economic development, grain for green policy and terrain were the main factors influencing the change of ecosystem service value along the road in mountains region.
