Study On The Master Layout Towards Ecology In The Middle Or Small-scale Cities In The Eastern Region Of Northwest China

In the strategetic background of speeding up urbanism, the eastern region of northwest China, as the chiefly important development region in the Western Development, will face the fast urbanism. The middle or small-scale cities, which are the principal part of urban system, will be the key to carry out the urbanism stratagem. Because the whole ecological environment in the eastern region of northwest China is frangible, the fast urbanism is in contradiction with ecological resumption and protection. It is very instant to discuss the urban master layout towards ecology.The dissertation is mainly in combination with the theory & methodology research and the practice & case research.Part one starts from research the basic urban ecological theories, such as ecocity, urban ecology, ecological urban planning, ecological resumption and so on, as well as the differentiation and analyse discrimnately of their relationship with urban planning. This is to try to seek the theoretical base of combining urban master layout with ecology. According to the correlated planning practice at home and abroad, on the basis of the noumenon theory of master layout in the middle or small-scale cities, the paper seeks for the applicable principals, characteristic and decision-making process of the urban master layout towards ecology. So the framework of the objective theory takes shape.Part two investigates the macroscopical ecological conditions, the deveolopment of middle or small-scale cities and their master space layout. Based on investigation above, the article educes the main factors in which urban master layout is restricted by frangible ecological environment and the main influences of urban layout pattern upon urban ecology. Finally the dissertation analyses the practice and cases of urban master layout and gives some advice about the master layout of middle or small-scale cities in the eastern region of northweat China, so as to adapt to their sustainable development.
