基于土地利用变化的高阳县生态系统服务价值和碳排放风险研究
|
摘要
研究土地利用变化下区域生态系统服务价值和土地碳排放风险的变化,对于了解土地利用变化的生态环境响应,促进区域经济与环境的协调发展,实现低碳土地利用具有重要意义。以高阳县为研究区,基于2009年和2016年土地利用数据,利用网格法划分评价单元,运用模型法定量评价了生态系统服务价值和土地碳排放风险,并分析了时空演变特征,最后对二者进行了相关性分析。结果表明:2009—2016年高阳县土地利用变化特点为建设用地迅速扩张、水域等生态类用地大量减少;生态系统服务价值总体偏低且研究期间呈下降趋势,县域东中部地区整体高于西部地区;土地碳排放风险总体偏低但在研究期间呈上升趋势,县域中西部地区整体高于北部和东南部地区;土地碳排放风险与生态系统服务价值存在显著负相关关系,表明生态系统服务分析在土地利用碳排放研究中应用的可能。
Study of the changes of regional ecosystem service value and land carbon emission risk under land use change has great significance for understanding the ecological environment response of land use change, promoting the coordinated development of regional economy and environment, and achieving low carbon land use. We took Gaoyang County as the research area. Based on the land use data of 2009 and 2016, we used the grid method to divide the evaluation unit, and used the model method to quantitatively evaluate the ecosystem service value and land carbon emission risk, then analyzed the temporal and spatial evolution characteristics, and finally analyzed the correlation between the two. The results showed that the characteristics of land use change in Gaoyang County were the rapid expansion of construction land and the reduction of ecological land use such as water area from 2009 to 2016. The ecosystem services value was generally low and declined during the study period, it was higher in eastern and central areas of the county than the western area. The land carbon emission risk was generally low but rose during the study period, it was higher in the western and central areas of the county than the north and southeast area. There was a significant negative correlation between the land carbon emission risk and the ecosystem service value, indicating the possibility of application of ecosystem service analysis to land use carbon emission research.
