Purpose The purpose of this paper is to analyze the characteristics of spatio-temporal dynamics and the evolution of land use change is essential for understanding and assessing the status and transition of ecosystems. Such analysis, when applied to Horqin sandy land, can also provide basic information for appropriate decision-making. Design/methodology/approach By integrating long time series Landsat imageries and geographic information system (GIS) technology, this paper explored the spatio-temporal dynamics and evolution-induced land use change of the largest sandy land in China from 1983 to 2016. Accurate and consistent land use information and land use change information was first extracted by using the maximum likelihood classifier and the post-classification change detection method, respectively. The spatio-temporal dynamics and evolution were then analyzed using three kinds of index models: the dynamic degree model to analyze the change of regional land resources, the dynamic change transfer matrix and flow direction rate to analyze the change direction, and the barycenter transfer model to analyze the spatial pattern of land use change. Findings The results indicated that land use in Horqin sandy land during the study period changed dramatically. Vegetation and sandy land showed fluctuating changes, cropland and construction land steadily increased, water body decreased continuously, and the spatial distribution patterns of land use were generally unbalanced. Vegetation, sandy land and cropland were transferred frequently. The amount of vegetation loss was the largest. Water body loss was 473.6 km2, which accounted for 41.7 per cent of the total water body. The loss amount of construction land was only 1.0 km2. Considerable differences were noted in the rate of gravity center migration among the land use types in different periods, and the overall rate of construction land migration was the smallest. Moreover, the gravity center migration rates of the water body and sandy land were relatively high and were related to the fragile ecological environment of Horqin sandy land. Originality/value The results not only confirmed the applicability and effectiveness of the combined method of remote sensing and GIS technology but also revealed notable spatio-temporal dynamics and evolution-induced land use change throughout the different time periods (1983-1990, 1990-2000, 2000-2010, 2010-2014, 2014-2016 and 1983-2016).

Tailan River Basin

Based on the land use data observed over the Tailan River Basin (TRB) during the years 1990, 2000, 2005 and 2008, fractal theory is adopted and applied to expound spatial distribution characteristics and variation law of land use change in the arid inland TRB, Xinjiang, China. The results demonstrate spatial fractal characteristics in all land use types. The analysis indicate that the fractal dimensions of different land use types in the TRB are in the order of waters > industrial, mining and residential areas > farmlands > grasslands > unused lands > woodlands in 1990, and in the order of waters > industrial, mining and residential areas > grasslands > farmlands > woodlands > unused lands in 2000, and in the order of waters > industrial, mining and residential areas > grasslands > woodlands > farmlands >unused lands in 2005, and in the order of waters > industrial, mining and residential areas > grasslands > unused lands > woodlands > farmlands in 2008. The fractal dimension values of land use in the TRB in 1990, 2000, 2005 and 2008 are calculated as 1.5993, 1.5986, 1.6079 and 1.6348 respectively. Fractal dimension of land use in the basin is decreased at first then increased, the spatial structure of land used exhibit complex trend, while the land use types show an increase trend. The stability indexes of spatial structure of land use in the TRB in 1990, 2000, 2005 and 2008 are 0.1720, 0.1563, 0.1435 and 0.1428 respectively. These values suggest that the stability of the spatial structure of land use in the basin is gradually decreased.
