摘要
为探讨县域尺度土地利用变化的生态效应,以武陵山区慈利县为研究区,基于2006—2016年土地利用变更数据,根据单一土地动态度及土地利用综合指数,对县域土地利用的面积变化和结构变化进行分析,分别从县域尺度和乡镇尺度分析了慈利县的生态系统服务价值和单一类型生态系统服务价值的动态演变。研究结果表明:2006—2016年慈利县土地利用变化呈“三增四减”的态势,其中建设用地面积明显增多,生态用地和未利用地面积显著减少;2006—2016年慈利县生态系统服务价值减少了0.25亿元,其中美学景观提供价值量减少最多;各乡镇的生态系统服务价值变化存在较大差异,其中江垭镇变化最明显,其他乡镇变化相对较小。
In order to explore the ecological effects of land use change at the county-scale,taking Cili County in Wuling mountain area as the research object,based on the data of land use change from 2006 to 2016 in Cili County,the author analyzed the area and structure changes of land use in the county by using single land dynamic degree and comprehensive land use index.The dynamic evolution of ecosystem service value(ESV)and single-type ESV in Cili County were analyzed at county and township scales respectively.The results show that the land use change in Cili County from 2006 to 2016 shows a trend of"three increases and four decreases",in which construction area increases significantly,while ecological land area and unused land decreases significantly.From 2006 to 2016,the ecosystem service value of Cili County decreased by 25 million yuan,of which the aesthetic landscape provided the most value reduce;There are great differences in the value change of ecosystem services among the townships,among which Jiangya Town has the most obvious change,while other townships have relatively small change.
