Study On The Urban Land Use Change Based On High Resolution Remote Sensing Imagines

City is a complex adaptive system with the typical characteristics of the dissipativestructure. This system and the external environment affect each other through the exchangeof materials and energy in a non-linear mechanism, just like the synergy processing amongits various elements, and in this way the function promotes the city and its factors' changeand development all the time. As the carrier of city's economic and societal activities urbanland use is in the changes constantly. Generally this change can be divided into internalurban area and external urban area. Urban land's utility is meeting the demand for spaceoccupation of urban economic and societal activities, and the urban land coverage canchange lonely without the company of the change of land use type. So complete urban landuse change should include two aspects what are changes in urban land use types andintensity of urban land use changes. Under the support of high resolution remote sensingimagines, we can gain the information of urban land use change promptly and truthfullyincluding type, structure and intensity, and can efficiently improve the development of thedetail-scale dynamic monitoring of land use change. As a result urban government canacclimatizes itself to the environment of urban land use in a fast urbanization age moreeasily.Based on the techniques of RS and GIS, taking the high resolution remote sensingimagines as the basic sources of information that is utilized later, this paper analyses theurban land use change of Shijiazhuang city in two aspects, urban built-up area and urbanfringe area, from 1994 to 2002.According to the dimension of the urban land use change, we build up our analysisdepending on the high resolution remote sensing imagines; and the spatial resolution is lmeter in the both two imagines, when we select the basic information sources.Referring to the meaning and the characters of LUCC, we define urban land usechange as the one including land use type and land use intensity two aspect.When it comes to the selection of index, we adopt four indicators what are land usechange rate, land use intensity change rate, land use change comprehensive dynamic rateand urban land use structure dominance. To some extent, the indicators using inconjunction with each other can reduce the limitation of a single indicator, when they areused in describing the process of urban land use change. During the time 1994 to 2002, one character of Shijiazhuang city urban land usechange is the dominance of land use structure adjusting in internal area of the city wherethe range of variation isn't very prominent, and the other is the fast changing in externalarea of the city where farming land drop so speedily in contrast.We should adopt the measure to improve the efficiency of land use throughaccelerating the rate of change in land use management. Another aspect we need pay moreattention is the reducing of farming land. Some countermeasure can been used to guaranteethe farm land change in a rational way.
