Abstract:: Analysis of dynamic monitoring of district land utilization is an important part of the land utilization research and provides the basis for rational utilization of land area and the government’s macro-control.In order to grasp information and trend of land use situation and dynamic as well as provide the auxiliary means for the dynamic balance regulation of the land utilization and the protection of ecological environment,Kowloon County was chosed as the research area in this paper.Using three Landsat TM satellite images in the year 1994,2000 and 2007,remote sensing (RS) and geographic information system (GIS) technology,we finished the dynamic monitoring and analysis in land utilization changes of Kowloon County of 13 years.Through variation diagram in the distribution of land utilization,transition matrix land utilization,various condition of Kowloon County land use types can be reflected.The net increase of the woodland area amounts to 170.96km² ,where 169.94km² of grassland is the net change into the woodland and 1.9km² dryland is the net change into the woodland.The condition concludes the woodland mainly changes from dryland and degraded grassland.The net increase of the glacier area amounts to 18.67km²,the net decrease of the bare land area amounts to 6.14km².The condition concludes Natural Forest Protection Project and Grain for Green Project has played a remarkable role in the local soil-water conservation.We used Markov model to predict Kowloon County land use trends of the next few decades.The woodland area will be 2% increments every 13 years.The glacier area will be 1.5% increments every 13 years.The trends conclude the ecological environment of Kowloon County wil be the healthy development in the future and provide the scientific basis for environment improvement in Kowloon County.
