Carbon Emission Evaluation in Jinan Western New District based on Multi-source Data Fusion

doi:10.5814/j.issn.1674-764x.2021.03.004

Abstract

Abstract:

Carbon emissions caused by human activities are closely related to the process of urbanization, and urban land utilization, function vitality and traffic systems are three important factors that may influence the emission levels. For clarifying the space structure of a low-carbon eco-city, and combining the concept of “Combining Assessment with Construction” to track and contrast the construction of the low-carbon eco-city, this research selects quantifiable low-carbon eco-city spatial characteristics as indicators, and evaluates and analyzes the potential carbon emissions. Taking the Jinan Western New District as an example, diversity of construction land, travel carbon emission potential, and density and accessibility of adjacent road networks in the overall urban planning were measured. After the completion of the new urban area, the evaluation mainly reflected certain factors, such as the mixed degree of urban functions, the density of urban functions, the walking distance to bus stops and the density and number of bus stops. Dividing the levels and adding equal weights after index normalization, the carbon emission potential is evaluated at the two levels of the overall and fragmented areas. The results show that: (1) The low-carbon emission potential areas in the planning scheme basically reached the planned goals. (2) There is inconsistency between districts and indicators in the planning scheme. The diversity of construction land and the accessibility of the adjacent road network are relatively small; however, there is a large difference between the travel carbon emission potential and the road network accessibility. (3) Carbon emission potential after completion did not reach the planned expectation, and the low-carbon emission potential plots were concentrated in the Changqing Old City Area and Central Area of Dangjia Town Area. (4) The carbon emission indicators varied greatly in different areas, and there were serious imbalances in the density of public transportation lines and the mixed degree of urban functions.

West Railway Station Area	40.81	Construction began in 2009. The core growth pole of Jinan Western New District has both external transportation, residential, and business functions. The planning goal is to create a new Qilu portal, a new commercial port in Quancheng, a new city center and a new cultural highland
Changqing Old Town Area	97.19	Formerly defined as Changqing County, removed in 2001 to set up a district. The road network density in the central area is high, and the buildings are mainly low-rise. It is the most representative old city in the study area
University Science and Technology Park Area	36.33	Constructed in 2003, in total 12 universities were located in this area until 2017.

Dangjia Town Area	71.97	An important industrial cluster in Jinan, above the east-west development axis of one city and two districts proposed in the master plan of Jinan. It is the ecological isolation zone between the main city and the new western city. The southeast has many exposed mountains and the ecological environment is sensitive
Gushan Town Area	68.67	The terrain is dominated by hills, and due to the terrain, the distribution of construction land is scattered. The Jinyun Lake reservoir is located in the middle, and the ecological environment is good. In the latest Jinan City Regulatory Planning Division, it is designated as a university town area together with the University Science and Technology Park Area
Duandian Town Area	39.37	The belt-shaped development along Jingxi Road has developed medical industry, industry and logistics. The current buildings are mainly low-rise and multi-story buildings, and there are many rivers in the area. It is an important water source protection area
Pingandian Town Area	83.66	The belt-shaped development along Jingxi west Road has been affected by the establishment of Jinan Economic Development Zone. In recent years, industrial development has been rapid. The current buildings are mainly low-rise and block-story buildings. The Jixi Wetland is the ecological core of Jinan Western New District, with superior ecological conditions
