A Study On Urban Afforesting And Greening Construct Of Lanzhou City

It experienced a long and tortuous process, the mankind from ignorance, the original to civilization, from fishing and hunting civilization to agriculture development of civilization, and from agricultural to industrial civilization. Nowadays, the world is facing another change of social development model. It is that industrial civilization is changing to the green civilization. Green thinking is the result of the awakening of Human Ecology recent decades, which awakened people to re-examine their own behavior, thinking and living conditions. In recent years, with the worldwide process of urbanization is accelerating and the environmental problems intensifying, the human increasingly recognized that urban greening is an important means to improve the urban ecological environment. The paper select Lanzhou City, which is serious short of urban afforesting and greening, and try to offer useful suggestions for Lanzhou urban afforesting and greening.The full paper is divided into seven parts. The first part is the introduction, mainly describes topics on the background, significance, progress at home and abroad of the research, and the paper does a prospect of the 21st century urban Eco-green. On this basis, the paper proposed the research methodology and research ideas. The second part is the basis of relevant theories(Man land relationship, the Sustainable Development theory, the Green theory, Landscape Ecology theory), circumscribe relative concept of the research. The third part define the scope of the study area,step back the history of urban afforesting and greening; analyze the problems and implementation of the urban afforesting and greening; At last, the paper to assay the present situation of Lanzhou city. The fourth mainly to address an issue of urban afforesting and greening, and elaborate implementation and destination of urban afforesting and greening; bring fixed targets of urban afforesting and greening. The fourth mainly to meditate spatial layout of urban afforesting and greening, the overall pattern of green can generalize"one river-two wing-three axis-three area–four city zone."The six part of the paper countermeasures and suggestions of c construction of urban afforesting and greening. In the end, the paper to point out the main conclusions and problems and lack of the study.
