Abstract:Ecologically-sustainable land use is essential for human beings to survive. The changes to land use in mountainous areas, the resources used, and the environmental effects caused by people are reflections of changes in people-land relations mountain regional system. It is important to understand and discuss the spatio-temporal distribution and mechanisms of ecologically-sustainble land use for maintaining regional ecological balances, and for guiding sustainable economic and social development. Based on the land use spatial analysis model and meta-analysis method, the spatial pattern of changes to ecologically-sustainble land use, and the profit and loss of ecosystem services in Jinggangshan were analyzed. Logistic regression and geo-detectors were used to diagnose the spatial orientation characteristics and measure change over time of ecologically-sustainble land use.The results showed:(1)From 1990 to 2015, ecologically-sustainble land use in Jinggangshan has changed significantly, showing a continuous downward trend, which is especially obvious near urban area where the land is used for construction. (2) Dominant factors influencing ecologically-sustainble land use over time are population numbers and industrial development. In the spatial change pattern, the distance from the river and the distance to the regional center have a great influence on changes ecologically-sustainble land use in Jinggangshan. (3) From 1990 to 2015, the value of ecosystem services decreased, but the rate of decrease slowed down gradually, and the annual average decrease from the years 1990-2000 years was greater than the average annual decrease during the years 2000-2015.Woodlands provided the greatest contribution to ecosystem services. Countryside revitalization efforts in the mountainous area should be guided by the value of ecosystem services, and aim to achieve optimal coordination between farmers' livelihoods and ecological security. Meanwhile, making use of geographical resources in the mountains and strengthening the integration of the three industries will promote "the countryside revitalization" in the mountains.
