中文摘要	绿洲空间发育适宜性指的是绿洲发育相对空间某一区位的适宜程度.针对目前尚缺乏定量方法分析空间区位相对绿洲发育适宜程度的问题,根据绿洲发育特征以及与空间各环境变量之间的关系,利用地理信息系统基于准则的多要素综合分析功能,构建了绿洲空间发育适宜性研究的数学模型,阐述了该模型的实现步骤和应用过程.
英文摘要	The .suitability of oasis development means the suitable degree which oasis development relative to the specifically space. It contains three meanings: 1) Oasis always lies in specifically position but any-place; 2) The place in which oasis lie is changeable. Oasis steadily develop when every factors are suitable to oasis, otherwise, oasis will degenerate; 3) Exploiting oasis might follow the rule of oasis develpment so that we could keep oasis sustained development. According to the features of oasis development, thinking the relationship between spaces the oasis lies and the factors dominating development of oasis accords with the multi -factors liner equation; S =Wi Aj + W2AZ+ W;iA3+ +WmAm, in equation, W; is weightiness of each factor, Ai is the contribu-tion of each factor. Based on the GIS, the process of model design and suitability analysis are discussed.1) Selecting the factors which directly and steadily control oasis development and deciding which data-sets will need to be as inputs; 2) Creating data from existing data and reclassify each dataset to a com-mon scale; 3) Weighting all the datasets and giving each a percentage influence, the higher the percent-age, the more influence a particular dataset will have in the uitability model; 4) Simulating to combine datasets based on GIS software ArcGis 8. 3.
