| Urban is an environment massed by people, the environmental problem is getting serious day by day with urbanization. Estimating is one of the important ways to ameliorating urban ecology &improving living environment which is precondition of sustainable urbanization. This leads a great deal of research on estimating and programming of urban landscapes. Voice of "introducing forest into urban" and building urban forest ecology network is getting regarded recently, in particular.After knowing and grasping city ground-using actuality by using 3S technology which was based on SOPT-5 satellite data as main information source, the urban landscapes were classified, the interrelated landscape ecology was estimated, and beneficial discussion was made on the construction of Chengdu Urban Forest Ecology Network lastly in this dissertation. Main research contents include four aspects:(1) The study area which is inside the circle freeway of Chengdu city main urban landscapes were classified, and grasped urban landscapes elements distribution actuality.(2) The patch-level and landscape-level index's analysis &estimating were made on the study region landscapes elements by using landscape ecology theory. Landscape diversity &equality is low, the urban forest and general greenland's proportion is also low, and the distribution is not equal even. Large-area urban forests with interior habitat were lack; connectivity of interspaces is also absence which went against species intercommunion. Those were not good enough to improving Chengdu city environment as a whole(4) After discussion on the layout form of Chengdu Urban Forest Ecology Network, some maneuverable and macroscopically guidelines of the construction of Chengdu UrbanForest Ecology Network in study region was funded.(5) Logical foliage species programming and vegetation scheme were educed which was based on the goal of construction of Chengdu Urban Forest Ecology Network...
