Spatio-temporal differentiation of residential land for coastal town: A case study of Dalian Jinshitan

Abstract

Based on SPOT5 satellite remote sensing images and land use data in five time phases covering the period 1988-2012, the distribution characteristics, spatial differentiation processes, and driving mechanisms affecting the residential land of the Jinshitan Tourist Resort were studied. The work included a combination of GIS technology, adoption of the differentiation index D, and the multi-group differentiation-measure model D (m). The results provided a basis for the following conclusions: 1) From 1988 to 2012, the degree of differentiation of the rural residential land first decreased, and then increased. The general residential, commercial residential and garden-house land-types all showed declining trends, of which the garden-house type presented the most intense volatility. 2) The overall background of the traditional residential land type was gradually replaced by a new residential land type, and the total area of residential land increased year by year, significantly improving the overall residential conditions. The areas of the new residential land type showed growth, and were increasingly widely distributed in the coastal tourist resorts, transportation corridors, and scenic areas. 3) Government policy, social differentiation, market mechanisms, and individual choices (along with other factors) were mutually promoted, although still restrained. However, all of these factors interacted to constrain the developmental direction and the processes affecting tourism real estate in the Dalian Jinshitan Tourist Resort.

Detection and Simulation of Urban Expansion and Socioeconomic Segregation in the Greater Paramaribo Region, Suriname

“…Residential characteristics were used to gain insight into the socioeconomic status of the population (Munyati et al ; Yang et al ; Sun et al ). Visual differentiation was based on five spatial residential characteristics (Table ).…”

Spatiotemporal Fragmentation of Urban Residential Land Use: A Case Study from China

“…In the context of socio-economic transition, Nantong's residential development is also closely linked to the dynamics of the land market and local governments' land planning policies [43]. In the early period of China's market-oriented reform [44], economic growth and people's desire to attain better living conditions were the driving force behind investment in housing estates [45]. Since 2003, Nantong has experienced a boom in its housing estate market [3] and an unprecedented scale of housing development in newly established zones.…”

Geospatial Analysis of Urban Expansion Using Remote Sensing Methods and Data: A Case Study of Yangtze River Delta, China

“…In recent years, with the increasing availability of remote sensing data, investigating urban development patterns through the integration of different sources of remote sensing information has become a popular avenue of urbanization research. For example, studies of the intensity and mode of construction land expansion in developed and developing countries using multiple-source remote sensing data and the Defense Meteorological Satellites Program/ Operational Linescan System (DMSP/OLS) night-time light data revealed the effect of policy factors at different economic development levels and of heterogeneous regional landscapes on urbanization [12][13][14]. Following the implementation of the Chinese national policy of reform and opening-up in the 1980s, the spatiotemporal changes of Chinese cities and their driving factors have attracted increasing attention from researchers [15][16][17][18][19].…”
