Study On The Development Of New Urban Area Based On Smart Growth

The emergence of new urban area is accompanied by the rapid development of economyand urbanization of our country, it is a new area that is built in the outskirts of the city, inorder to seek bigger development space. At present, the new urban area has become a newgrowth point of China’s city development. But the new urban area did not solve the problemsuch as urban sprawl, traffic jam and environmental pollution of the old city fundamentally,due to the lack of guidance of new planning concept. Smart growth is a new mode of citydevelopment that proposed on urban sprawl by America last century, this mode aims atprotecting the ecological environment, promoting the coordinated development of urban andrural areas and improving the quality of life, through reasonable planning and comprehensiveland use. The study of smart growth abroad has been relatively mature, and its application isextensive, but in China it is still in the initial stage, and has not formed a complete set oftheory system suitable for China, there is not so much application in city planning andconstruction.In this paper, we started from the current situation of domestic and international city andthe development of new urban area in China, discussed some problems existing in the citydevelopment, introduced the background and application of smart growth, and applied thetheory to the land use evaluation of new urban area, determined the feasibility of smartgrowth’s application in China. For this purpose we established a set of evaluation indexsystem on land use according to the principle of smart growth, with "smart degree" as theevaluation object, evaluated the effect of land use on social benefits, environmental benefitsand economic benefits, and determined the weight of evaluation indexes at all levels by usingthe improved entropy method, calculated the figure of smart degree of comprehensive landuse by means of multi-factor assessment method. Through calculation and analysis, we cameto the conclusion that it is feasible the smart degree evaluation of this system on land use inour country’s new urban area, and it has a significance of reference to the evaluation of landutilization.This paper combined the overall planning of Xi-Xian New Area, selected the statistical data in2010, the planning data in2015and2020, and analyzed the case with the index systemand method. Through the analysis, we confirmed the feasibility of the index system and theevaluation method, and found that the figure of3years’ smart degree showed a rising trend,by using the planning concept of smart growth in the planning and construction of Xi-XianNew Area. This shows that smart growth has important theoretical value to the developmentof new urban area in our country, we hope to extend the application of this theory to theplanning and construction of city and new urban area, and even the construction of smalltowns and new towns nationwide.
