摘要
本文选取2000、2010和2018年作为研究时段。在分析洞庭湖区域土地利用现状情况下对其生态系统服务价值进行测算与评估。研究结果表明:2000—2018年,建设用地、湿地面积呈增加态势,耕地、林地面积呈减少态势,草地、未利用地面积虽有所减少但变化不显著。2000—2018年,洞庭湖区域生态系统服务总价值由339885.68×10^(8)元增加至340054.88×10^(8)元,共计提升1692×10^(8)元,呈先升后降再升的变化趋势。
Based on the actual situation of Dongtinghu area and important nodes of social and economic development,2000,2010 and 2018 were selected as the research time periods and the ecological service value of Dongtinghu area was assessed based on land use change data.The results show that during 2000—2018,the construction land and wetland increase,the arable land and forest land decrease,and the area of grassland and unused land decrease but the change is not significant.The total value of ecosystem services in Dongtinghu area of Hunan increase from 339885.68×10^(8)yuan to 340054.88×10^(8)yuan during 2000—2018,with a total increase of 1692×10^(8)yuan.It shows a trend of change of firstly increase,then decrease and finally increase.
