【摘要】 为生态系统服务价值的深入研究提供理论参考。运用灰色关联等模型方法,构建生态系统服务价值评价指标体系,对贵州省黔东南州生态系统服务价值及影响因素的动态演变进行分析。结果表明:2010-2015年,该州生态系统服务总价值呈降低趋势;生态系统服务价值与影响因素间的时间动态关联度及各指标层与生态系统服务价值的空间演变关联度均在中度以上,且以强度居多;各县市受各指标层因素的影响不同。对深入研究生态系统服务价值的演变驱动机制有一定的参考作用。更多还原

【Abstract】 In order to provide theoretical reference for the in-depth study of ecosystem service value,the evaluation index system of ecosystem service value was constructed by using the grey correlation model,and the dynamic evolution of ecosystem service value and influencing factors in Qiandongnan Prefecture of Guizhou Province was analyzed.Results:The total value of ecosystem services in Qiandongnan Prefecture had a decreasing trend from 2010 to 2015.The temporal dynamic correlation degree between ecosystem service value and influencing factors and the spatial evolution correlation degree between each index layer and ecosystem service value are all above moderate and most of them were strong.Each county and city suffer the influence of each index layer factor to differ somewhat.It could be used as a reference for the further study of the evolvement driving mechanism of ecosystem service value.更多还原
