And new urbanization emphasizes the coordinated development of urban and rural areas,and it provides new idea for constructing new relationship between urban and rural areas and solving issues of agriculture. This paper sees new urbanization as background,takes Jinan City as an example to study the constraints on coordinated development of urban and rural areas,path choice,urban and rural primary missions. The strategies and measures are finally put forward. This paper will help to solve the problem of the uncoordinated development of urban and rural areas,enrich the research content of urban and rural areas,and provide a reference for other cities.展开更多

Previous studies mainly focus on the ore characteristics, metallogenic setting and the granites in the mining area, and there is still controversy on the ore genesis. Recent research has revealed that the iron ore bodies are spatially closely related to diabase rocks, especially those in the Makeng Fe deposit. Diabase dykes are widely distributed in the Makeng, Luoyang, Zhangkeng and other iron deposits,展开更多

These are the new summations of the practice of socialism with Chinese characteristics, and the latest achievements in the theory of the political economics of socialism with Chinese characteristics."People-centered"is both the starting point and final purpose of coordinated economic development, an accurate mastery of social and economic development rules, and also the foundation and specific manifestation of coordinated development between people and society. People's subjectivity, coordinated inclusiveness and dialectics of development are the characteristics of coordinated economic development. Regional coordinated development, urbanrural coordinated development, industrial coordinated development, coordinated development of national defense and economic construction, supply and demand coordinated development, ecological coordinated development and interacted coordinated development of the global economy are the important relationships of coordinated economic development that we have to recognize and handle properly.展开更多
