In this paper, taking the campus planning of Sanxia University as an example, the natural ecological factors in the planning were analyzed. An ecological sensitivity model was drawn out after comprehensive appraising. In combination with the requirements for campus planning, a mode of eco-division for land use and the development intensity control was proposed. The stress on ecology arrangement and construction of campus with consideration of local conditions is suggested. Thus the concept of 'design in consideration of the nature and in coordination with the environment'is realized.
