Title: $The Process Study of LUCC in Typical Vulnerable Ecological Region——A Case of the Mountain Areas of Southern Ningxia Hui Autonomous Region
Abstract: The study of LUCC process is an important part of LUCC study.In order to get the status of LUCC in the mountain areas of southern Ningxia Hui Autonomous Region,the LUCC process is studied based on the integrated technology of Remote Sensing(RS)and Geographic Information System(GIS).After interpreting the Landsat MSS/TM remote sensing date of 1975,1985 and 2001,it gets the study area originality data of LUCC in three periods.Using these data,the change extent,dy- namic change index and state index of LUCC are studied.The result indicates that farmland has a high input speed,but the grassland,woodland and water have a high output speed from 1975 to 1987.So,the area of farmland increases and the area of grassland,woodland and water decrease greatly.The LUCC is unbalanced.But in the period of 1987~2001,the grassland,wood- land and water begin to input and the farmland begins to output.The LUCC also is unbalanced.In the whole period of 1975~2001,besides city land and unused land,the other kinds of LUCC have a curve change.The whole LUCC is balanceable.
