摘要
以沂河流域为例,在ARCGIS10.2中解译沂河流域2005年和2015年遥感影像,得到两期土地利用数据。并分析了2005—2015年沂河流域土地利用及其变化情况,以Costanza生态服务价值计算方法为参考,分析了沂河流域生态服务价值变化情况。结果表明:研究区耕地面积显著减少,但生态服务总价值却从2005年的2 338 964万元上升到2015年的2 427 039万元,上升了约3.77%,这主要是由于林地面积的增加带来的较高的生态服务价值。
Taking Yi River Basin as an example, interpreted the 2005 and 2015 remote sensing image of Yi River Basin in ARCGIS10.2, finally got two issues of land use data. Analyzed the 2005-2015 Yi River Basin land use change, and referring to the calculation method of ecological service value of Costanza, analyzed the change of ecosystem service value of Yi River Basin 2005-2015. The results showed that the cultivated land in the study area was significantly reduced, but the total value of ecosystem services has increased from 23 389.64 million yuan in 2005 to 24 270.39 million yuan in 2015, mainly due to the ecological service value brought by the increase of ecological service forest area.
