Make use of the principle of the view ecology to carry on a research to the city view space structure and form， is the valid means that announces to public the city ecosystem condition and the space variation characteristic， to the change city ecosystem environment，support the ecosystem balance， carry out the strategic target that the city co-exist with nature， constuct the ecosystem city to have important This text with the 徐 state downtown 1987 and 20002 period TM/ETM+image for main data source， adopt the ERDAS IMAGINE 6，ArcGIS 0 analyze the software FRAGSTATS with the view structure 3， carry on the contrast analysis to the view structure and form of the xv state downtown 1987 and Main research result is as follows: From 1987-2000 years， farmland view，constuct to use more obvious variety of the view main factor structure and form existences such as a ground of view and the woodland view s， appear this situation that eliminates that to grow， the performance uses a ground of view to extend further for the construction and more the rule become a slice， the construction of 2000's using a ground of view area is 200% of 1987 many;But the farmland view，the woodland view and other land views are let up in the view with broken up， the farmland area of 2000 compared the farmland area of 1987 to reduce a 7595 hms 2， but the woodland area of 2000 then compare 1987 reduce a 675 hms
