- Abstract:
-
Using the four-year data of remote sensing images accepted in 1964, 1988, 2005 and 2010, land-use situation of Wulingyuan in these four years was monitored. With the help of GIS space analysis, land-use area change, change in using level and the transfer of land category of Wulingyuan during the last 40 years were quantitatively analyzed. The results showed that the land use structure of Wulingyuan changed obviously with the influence of natural factors and human activities. During the research period, the water bodies and unused land decreased slowly. With the influence of the cities’ economic development, the area of crop land decreased substantially. Orchard, construction land and the road increased in different degrees, in which the change rates of orchard and construction land were the fastest in all land use types. Areas of wood land remained the least changes during the 40 years. According to the types of land use transfer matrix, various land types had different degrees of conversion. For example, crop land was converted principally into orchard and construction land, and it was mainly converted from orchard. Crop land, orchard and construction land were transferred frequently to each other. Substantial increase in construction land areas were primarily caused by the occupancy of crop land. Through a series of research and analysis, the land use in the research area was still at the developing stage, and the land use patterns were deeply influenced by human farming and living activities.
