Abstract

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
