| With the rapid development of urbanization,urban industries are constantly adjusting,optimizing and upgrading in the context of market economy.At the same time,the spatial distribution pattern of the industry is also being adjusted and reorganized.To formulate a sound urban development policy,we must have a correct grasp of the city’s development trends and development laws.Understanding the changes in urban industrial spatial structure can help us predict the trend of urban development,and then provide necessary for urban development,planning,management,etc.Decision support,at the same time,is also an important guarantee for the coordinated development of the city in terms of population,resources,economy and society.This paper takes the main urban area of Xining as the research object,and analyzes the main city of Xining City from 2000 to 2017 by using the indicators of industrial structure entropy,industrial structure similarity index,employment industry structure deviation and deviation-share analysis and grey correlation analysis.With the support of ArcGIS software,the evolution of industry and its internal industrial structure is analyzed.The evolution of the spatial structure of major industries in different periods is analyzed,and the influencing factors affecting the evolution of industrial spatial structure in the main urban area are discussed.The main conclusions of this paper are as follows:(1)From 2000 to 2017,the output value of the three industrial areas in the main city of Xining City increased by different degrees.The increase of the output value of the primary industry was small,the output value of the secondary industry and the tertiary industry increased substantially,and the output value of the tertiary industry gradually surpassed the first.The second industry.With the advancement of urbanization.The employed personnel continue to shift from the primary industry to the secondary industry and the tertiary industry,and the employment of the tertiary industry gradually exceeds the secondary industry.With the adjustment of industrial policies in Xining City,the development of the three industries in the main city is basically in line with the pace of industrial advancement in Xining.The adjustment of the industrial structure in the main urban area of Xining is generally moving in a healthy and orderly direction.(2)From 2000 to 2015,the development of the primary industry in the mainurban area of Xining City was mainly based on agriculture and animal husbandry.In terms of output value,it was mainly distributed in Chengbei District and Chengzhong District,but the output value declined to some extent.In the implementation of forestry,forestry has developed to a certain extent,but it is not distributed in the four districts;the proportion of fishery in the production is not large,and only in the urban area in 2010-2015;the agriculture,forestry,animal husbandry and fishery services accounted for The proportion is not large,and it will only be distributed in Chengbei District and Chengzhong District in 2010-2015.As the urban land use structure is mainly based on construction land,the urbanization has led to a continuous reduction in the area of cultivated land.Therefore,the research on the spatial structure evolution of the primary industry mainly starts from the spatial change of the cultivated land area in the main urban area of Xining City from 1990 to 2015.It is found that the cultivated land area of the main urban area shows a trend of gradually decreasing from the central city to the surrounding area.This has a direct relationship with the acceleration of urbanization in the main urban area of Xining City,in line with the law of urban development.(3)From the perspective of the entire main city,the distribution of large enterprises is mostly located in the core area of the main city of Xining.This is because the headquarters of these enterprises are mainly responsible for decision-making and office functions;the number of medium-sized industrial enterprises is relatively large,but large The number of industrial enterprises is relatively small.Overall,the layout of large and medium-sized industrial enterprises in the main urban area of Xining presents an X-shaped spatial distribution pattern,which is basically consistent with the spatial evolution of the urban area of Xining.In the long run,large and medium-sized industrial enterprises in the main urban area of Xining will gradually migrate from the core areas of the city due to the influence of land rent,transportation and policies.Industrial enterprises and factories will gradually move to industrial parks.Give full play to the industrial cluster effect,and also facilitate the unified layout management of the park,and gradually eliminate those high-energy-consumption and high-pollution enterprises that do not meet the economic development trend,so that the secondary industry in the main urban area of Xining City will develop in a healthy and orderly direction.(4)The tertiary industry mainly consists of six representative industries:accommodation and catering,finance,transportation,warehousing and postal services,real estate and scientific research technology,services and geological exploration,and information transmission computer services and software industries.Through the spatial distribution map and the nuclear density map,three time nodes(2009,2013 and 2017)were selected for comparison.It was found that these five industries were gradually spread from the core area of the main city to the surrounding area.The number of enterprises is increasing,and the direction of the south of the city is increasing along the Ninggui Expressway.(5)Through the study of the evolution characteristics of the industrial space structure in the main urban area of Xining from 2000 to 2017,combined with the particularity of the development of the main urban area,this paper divides the influencing factors of the evolution of the industrial space structure in the main urban area of Xining into four categories,namely natural factors.There are five categories of location factors,transportation factors,policy factors and urban industrial layout. |
