This thesis main targets the urban, a place where humans highly gathered. Beginning form the environmental for ecology of point and learning form the natural life pulse. By applying the natural function and rule of nature to the built area of urban space, we can take the worsening urban programs to be the targets of sustainable development. Hence, moving toward to the goal of sustainable developing. Let us compare the urban to a complex mosaic where joins the urban nature to its built environment. By returning the concept of ecological network to the analysis of true environment, we can unite the single relationship which analyzed by every true condition and try to return detail of near the true environment’s space system patterns and true conditions. We will take a future referable direction to be the normal or small scale urban space system design.
