Abstract: Based on landsat satellite remote sensing image and supported by ENVI and ArcGIS technology,Markov transfer matrix,barycenter transfer model and quadrant analysis method were used to study the changes of land use structure in the central urban area of the shrinking city Hegang from 2011 to 2016.The results showed that,from 2001 to 2016,the population of Hegang city kept losing,while the land for construction continued to increase.The change in quantity of land use types was “two increases and two decreases”,and the spatial distribution pattern basically remained unchanged.The transfer amount of cultivated land and forest land was large,and the transfer amount of water area was the smallest.The main source and destination of cultivated land were all forest land.Construction land expanded to occupy a large area of arable land,but the most transfer amount was changed for arable land,forest land.Among all types of land,the largest distance of shift of the center of gravity was the water area,and the smallest was the cultivated land.The center of gravity of cultivated land shifted to the southeast,and the center of gravity of construction land shifted to the southwest.The transfer direction of the two was opposite.The spatial evolution of construction land showed the characteristic of “north retreat and south expansion”,and the land in the Xing’an district has undergone dramatic changes.Construction land contracted mainly along the coal industry belt and rural settlements.

Key words: evolution of land use structure, urban shrinkage, the change of gravity center, quadrant analysis, Hegang city
