基于生命特征的城市竞争生态位评价分析
Contrastive analysis of urban competitive niche on vital signs
摘要
Abstract
From the perspective of system theory,city can be identified as a life of complex giant system with the characteristics of metabolism,growth and development,genetic variation,adaptability and emergency.Because urban life's location is stationary,it was necessary to investigate the competitive niche and competitive strategy for the long-term survival competition.This paper argues that the urban competitive niche is urban life in time and space on the relative specific position and functional relationship with the ecological environment.If urban life's competitive niche was stronger,it could obtain more external resources and be more probable to access a higher level of development.From the inherent nature of urban life,the index selection principles are proposed as broadly representation,quantitative analysis and conciseness.Nineteen indexes sorted into four different groups-metabolism (A),growing development (B),genetic variation (C),and adaptive and emergency (D) were selected.The method of information entropy was applied to determine the weight coefficients of each index,then a urban competitive niche evaluation model based on life characteristics was proposed.On this basis,the Yangtze River delta city group including Shanghai,Nanjing,Hangzhou and other 26 cities are selected as an empirical sample.we calculated urban competitive niche and 4 types of urban competitive sub-niche of the relevant city from 1984 to 2014.With the application of spatial correlation and correlation analysis to explore the sample data,the results showed that:① the overall cities' competitive niche present an increasing growth trend;② the cities' competitive niche growth was not balanced;③ the cities' competitive niche gradually emerged an obvious stratification;④ the cities' competitive niche closer to the first city closer maintained a faster growth;⑤ the effects of genetic variation of the ecological niche on the relatively changes of city competition is greater than other index.Therefore,this paper proposed the corresponding countermeasures and suggestions such as ① strengthening the function of the first city;② striving to improve the quality of the development of the urban group;③identifying the competitive strategy to achieve dislocation development;④ strengthening the complementary development and the first city or center city;⑤ increasing investment in fixed assets,science and technology,education and so on.关键词
