摘要: 以江西省临川区为例,采用2005、2010和2015年土地利用数据及相应的统计数据,估算临川区各乡镇土地生态系统服务价值,探究10年间其空间分异规律。在此基础上,开展基于土地生态系统服务价值与需求的土地利用生态可持续程度评价。结果表明,10年间临川区土地生态系统服务价值在选取的时点上呈下降趋势,主要归因于林地和水域面积的减少及建设用地面积的急增;空间上主要呈现地均价值量“四周高、中间低”的分布格局;土地利用可持续生态程度远高于临界值,生态环境水平较高;应保护林地和水域数量,维持林地规模的优势。

Abstract: Taking the Linchuan district of Jiangxi province as a case, using the 2005, 2010 and 2015 land use data and corresponding statistics, the value of land ecosystem services in Linchuan district towns was estimated, and its spatial differentiation law in the past 10 years was explored. On this basis, the evaluation of ecological sustainability of land use based on the value and demand of land ecosystem service was carried out. The results showed that the value of land ecosystem service in Linchuan district in the past 10 years was declining, mainly due to the reduction of forest land and water area and the rapid increase of construction land area. The spatial distribution pattern of land ecosystem service value was "high average value around and low average value in the middle". The sustainable ecological degree of land use was much higher than the critical value, the ecological environment level was high. The number of forest land and water should be protected in future, and the superiority of forest land scale should be maintained.

Key words: land use/cover, ecosystem service value, ecological sustainability, temporal and spatial change, Linchuan district
