Human settlement analysis based on multi-temporal remote sensing data: A case study of Xuzhou City, China

Abstract

To evaluate urban human settlement, we propose a human settlement environment development index (HSEDI) model by choosing vegetation coverage, land surface temperature, impervious surfaces, slope, wetness, and water condition as the evaluation factors. We applied the proposed model to Xuzhou City, Jiangsu Province, China. Landsat-5 Thematic Mapper (TM) images from 1998 to 2010 and digital elevation model (DEM) data with a 30-m resolution were used to calculate the values of the six evaluation factors. The HSEDI value in Xuzhou City was found to be between 2.24 and 8.10 from 1998 to 2010, and it was further divided into five levels, uninhabitable, moderately uninhabitable, generally inhabitable, moderately inhabitable, and inhabitable. The best HSEDI value was in 2007. The generally inhabitable region was about 100.98 km 2 , covering 30.87% of the total area in 2007; the moderately inhabitable region was about 170.58 km 2 covering 52.15% of the total area; the inhabitable region was about 32.03 km 2 , covering 9.79% of the total area; the percentage of the uninhabitable region was zero; and that of the moderately uninhabitable region was very small, less than 1.00%. Moreover, we analyzed the habitability in the respect of spatial patterns and change detection. Results show that the degraded regions of habitability quality are mainly located in the urban fringe and the improved regions are mainly located in the main urban and rural areas. Reason for the degraded habitability quality is the rapid progress of urbanization. However, the increase in urban green spaces and the construction of the main urban area promoted the improved habitability quality. Besides, we further analyzed socioeconomic and socio-demographic data to confirm the results of the habitability analysis. The results indicate that the human settlement in Xuzhou City is in a satisfactory condition, but some efforts should be made to control the possible uninhabitable and moderately uninhabitable regions, and to improve the quality of the generally inhabitable regions.

Evaluation and analysis on suitability of human settlement environment in Qingdao

“…As an objective and real-time RS data to record the light intensity of ground buildings and roads, nighttime light RS images [ 27 , 28 ] have been widely used in the identification and monitoring of social production and life [ 29 – 31 ]. According to the research results of Lu et al (2008), nighttime light data is selected as the evaluation index of the humanity factors of suitability of human settlement environment in Qingdao [ 32 ], denoted as Nighttime Light RS index.…”

Research on the Coordination between Economy and Human Ecological Settlement Environment

“…There is a lot of research literatures on the relationship between human ecological settlement environment and economy with the focus on the impact of economy on human ecological settlement environment and the relationship between economy and ecological environment. The development of the human ecological settlement environment cannot be separated from the economy, which is not only an important factor affecting the human ecological settlement environment, but also an important factor leading to the differences of the human ecological settlement environment in different regions [1][2]. The ecological environment influences the living environment of the city and then the human ecological settlement environment [3].…”

Assessing Suitability of Human Settlements in High-Altitude Area Using a Comprehensive Index Method: A Case Study of Tibet, China

“…The weight of indicators directly determines the reliability of the evaluation results. The methods such as expert scoring, analytic hierarchy process, and comprehensive evaluation approach were used to calculate the weight [9,23]. However, the methods of the above are subjective, which may lead to a lack of objectivity in evaluation results.…”
