Abstract: This paper carries out the research of theory and method of river basin major function oriented zoning(MFOZ),in a case of Yangtze River Basin,aiming at the deficiency of natural unit MFOZ and the need of river basin coordinated development,based on overview of the theories and research findings of space planning and river basin planning at home and abroad,and clarifies and combines the relationship between MFOZ and river basin planning.The paper first describes the connotation and characteristic of river basin MFOZ,and indicates essence is the organic combination of MFOZ and river basin planning.And then it constructs the logical ideas and method route.Furthermore,this paper selects zoning index,determines weight coefficient and constructs index system of Yangtze River Basin MFOZ,using Delphi and analytic hierarchy process(AHP),based on the principles including scientificness,systematicness,basin characteristics,balancing efficiency and fairness.The index system is divided into the target layer,rule layer,support layer and element layer.The target layer is the suitability of land spatial development;the rule layer consists of development constraints,development strength and development potential;the support layer contains ecological vulnerability,ecological significance,importance of agriculture,development density,industrialized level,the level of urbanization,economic development aftereffect and traffic advantage;the element layer is composed of 22 indicators;other factors and indicators are brought into auxiliary analysis.Finally,the Yangtze basin is identified into eight types of major function oriented regions,namely,promotion development zone,transition development zone,priority growth zone,key foster zone,general development zone,agricultural development zone,ecological protection zone and strictly protected zone,based on the orientation of development suitability and protection necessity,and on the dimension of ecology,agriculture and development.
