浑河流域近20年土地利用与生态系统服务价值变化研究

Study on the changes of land use and ecosystem service values in the Hun River basin in the past 20 years

生态系统服务价值变化研究是生态系统可持续性研究的热点和前沿。以浑河流域为研究对象,基于1995~2015年5期土地利用数据,采用生态系统服务价值当量因子方法,估算了不同土地利用变化对浑河流域生态系统服务价值的影响。结果表明:研究时段内浑河流域土地利用变化最大的是建设用地面积,生态系统服务价值贡献最大的是林地和草地,说明草地和林地是主要的贡献因子和敏感因子。本研究对全面了解浑河流域生态系统服务价值变化原因和生态文明可持续发展具有重要指导意义。

Research on the changing value of ecosystem services is the hotspot and forefront of ecosystem sustainability research.Based on the data of the ecosystem service value equivalent factor from 1995-2015,the influence of the ecosystem service value was estimated.The results show that the biggest land use change in the Hun River basin was the construction land area,and the largest woodland and grassland,reaching 94%,indicating that the grassland and woodland are the main contributing factors and sensitive factors.This study is of direct significance for comprehensively understanding the causes of ecosystem service value and the sustainable development of ecological civilization.
