Study on the Spacial Arrangement of Urban System Based on the Fragile Eco-environment in Ningxia Hui Autonomous Region

Urbanization is a necessary tendency of mankind progress in the 20 th century,urban system is the regional combining form of urbanization,whose occurrence and development have the necessary and close connection with the surrounding natural system,and this connection is adequately shown by the regional features,the spatial pattern and (the spatial) arranging rules of urban system. In the West China,urbanization development is generally backward,fragile eco-environment will necessarily lead to regional path of urbanization. Aimed at the main eco-environment question in Ningxia today,on the basis of the understanding of the five eco-environment subarea,the paper firstly attempts to analyze the regional features of the spatial arrangement of Ningxia's urban system,then clarify the development strategy of urban system's spatial arrangement,In the end,under the direction of the strategy,the paper proposes the spatial arrangement pattern of Ningxia's urban system.
