　The landscape ecological structure and the essential features of landscape ecological procedure are analyzed in this paper . Desert2oasis2river and canal corridor is the main landscape model. The grain of patches was large and the structure of landscape was simple. The mosaic pattern ,which was seriously depended on the water source ,was formed a sharp contrast . The landscape ecology was very fragile with poor function and lower resistance. The ecological process was instability. From the point of landscape ecological view ,the research theory of ecological environment building in arid area are put forward. The article expounded some basic principles about landscape evaluation ,management and ecological designing in arid area ,such as the development and protection of oases and the building in arid area ,such as the development and protection of oases and the building of green corridor , etc. The main questions or subjects of landscape ecology in arid area from now on are discussed and advanced.
