摘 要:本文基于贵溪市2010-2018年土地利用现状数据为基础,在“三生空间”视角下,使用土地利用转移矩阵表达了贵溪市土地利用转型过程,并通过生态系统服务贡献值从正负两方面量化土地类型转变造成的生态系统服务价值效应。结果表明,2010-2018年,贵溪市生态用地面积减少,生产和生活用地不断增加,其中林地生态用地减少最多,共计2 330.73 hm^(2),农业生产用地增加最多,面积为1 183.35 hm^(2)。贵溪市生态系统服务价值存在明显差异,整体上是“南北高,中部低”的空间分布。2010-2018年,从生态系统服务价值总体层面,贵溪市呈下降趋势。由于城市化和工业化的快速推进,生活用地和生产用地正在侵占大量生态用地,对生态系统服务价值产生负效应影响。对生态系统服务有正效应影响的主要土地利用转换类型是农业生产用地向各种生态用地的转换,“退耕还林还草”的实施是主要原因。贵溪市生态系统服务价值从2014年开始下降幅度得到缓解,但总体上生态系统服务价值负效应大于正效应。分析2010-2018年贵溪市土地利用转型及其生态系统服务价值效应对贵溪市国土空间规划和“生态文明建设”具有指导意义。Based on the land use status data of Guixi City from 2010 to 2018,and from the perspective of"theeliving spaces",the land use transfer matrix was used to express the process of land use transformation in Guixi City.The ecosystem service value effect caused by land type transformation was quantified from both positive and negative aspects through the contribution value of ecosystem services.The results show that from 2010 to 2018,the ecological land area in Guixi City decreased,while the production and living land continued to increase.Among them,forest ecological land decreased the most,totaling 2330.73 hm^(2),and agricultural production land increased the most,with an area of 1183.35 hm^(2).There are significant differences in the value of ecosystem services in Guixi City,with an overall spatial distribution of"high in the north and south,low in the middle".From 2010 to 2018,the overall value of ecosystem services in Guixi City showed a downward trend.Due to the rapid advancement of urbanization and industrialization,living and production land are encroaching on a large amount of ecological land,which has a negative impact on the value of ecosystem services.The main type of land use conversion that has a positive impact on ecosystem services is the conversion of agricultural production land to various ecological land,and the implementation of"returning farmland to forests and grasslands"is the main reason.The decline in ecosystem service value in Guixi City has been alleviated since 2014,but overall,the negative effect of ecosystem service value is greater than the positive effect.Analyzing the land use transformation and ecosystem service value effects of Guixi from 2010 to 2018 has guiding significance for the land spatial planning and"ecological civilization construction"of Guixi City.
