There is big economic development gap among such three districts as Chuan District of north Ningxia， the drought area in middle Ningxia and mountainous district of south Ningxia，and the urban and rural integrated development level on Chuan District of north Ningxia is much higher than mountainous area of south Ningxia and the drought area in middle Ningxia. Chuan District of north Ningxia closely connects the cities and countryside by depending on developed industrialized cities and small town construction of Ningxia Capital Yinchuan，Shizuishan and so on and by using the radiating role of “central city-small city”，boosts agricultural industrialization，modernization，and specialization to develop specific industries and cultural and tourism industries，which uses the urban and rural integration model of “using urban system construction to drive industrial structure upgrading”，however，the drought area in middle Ningxia and mountainous area in south Ningxia start with environment improvement，launch ecological emigration，adjust industrial structure and develop specific industries while conducting planted land withdrawal to grass land and desert management，which uses the urban and rural integration model by “developing specific leading industries at the premise of ecological and environmental construction”. The urban and rural integrated development in the west part of China should sufficiently let central city and small cities play radiating and driving role and the urban system construction must drive industrial structure upgrading and optimization. In ecological fragile areas，urban and rural integrated development should take ecological and environmental construction as the premise.
