  2. Based on the original data of tm in 1988, 1992 and 1998, then after some processing and analysis, the author have the thematic data of land - use by interpretation. on the basis of them, the author made the analysis of land - use for this area based on the spacial analysis of gis and the method of comparison between result of land - use classification as follows : the method of aggregating analysis, the analysis of urbanization, the analysis of the transformation rate of cultivated land, the analysis of the driving force of land - use change and the sustainable use of land. the conclusions may be demonstrated below : the cultivated land decreases with the patchs fragment ; road spreads radialy surround second - ring road ; the urban land expands quickly toward southwest along the major roads and be concentrative. rural land and industry increse rapidly with dispersing ; 0thers change slowly. the major driving forces of land - use change in this area are the rapid expansion of urban and rapid growth of population, foreign investment and the development of tertiary industry which was based upon the real estate. according the trendency of land - use change, the author consider that we must insist on the way of the sustainable use of land based on protecting the cultivated land

    在此基礎上，應用分類結果比較法，在gis各種空間分析功能（幾何量算、統計分析、疊加分析及緩沖區分析）的支持下，對該區土地利用變化進行了如下分析：土地利用綜合分析、城市化進程分析、耕地轉化率分析、土地利用變化因素分析及土地的可持續利用分析。結果表明：該區土地利用變化主要表現為耕地大量減少，斑塊破碎化；交通用地沿二環線呈放射狀向四周擴展；城鎮用地沿交通干線向西南方向擴張迅速，用地趨于集中；農村居民點和工礦業用地增加，用地趨于分散；其它用地變化較慢。這一用地變化的主導因素是城鎮用地擴展快、人口增長迅速、外資的大量投入及以房地產為主的第三產業的快速發展。
