In this paper, the spatial pattern analysis is made on the development level difference among the primary industry, secondary industry and tertiary industry in 11 counties and cities with Class-I ports. The analytical results show that the economic development is unbalanced and quite different in these counties of Yunnan Province with Class-I ports.
The mobility of population has its own rule. The paper bases on the theory of the floating population and the related data of shaanxi to do the research. The article also analyses the trend of population moving and spatial pattern of evolution by using the grey prediction and markov chain empirical analysis. From the paper, we can know that the best way to improve the efficiency of the population...
Aerosol optical thickness is a principal indicator to describe the atmospheric condition and the effect of aerosols on radiative transfer in the earth's atmosphere. In this study, the distribution and seasonal variation trends of AOT over the Yangtze Delta during 2001–2008 and World Expo were studied. The results show that the MODIS AOT550 was in good agreement with data obtained from four ground-based...
Since the beginning of 1998, China has begun its gradual and but incremental implementation of housing reform nationwide. Over the last decade, residential housing is leading the growth and expansion of China's real estate market. There is a need to understand how housing prices are spatially structured and differentiated in metropolitan areas in order to provide relevant information for policy makers...
The study choose Guangzhou city as study area to analysis the temporal and spatial change of land use and coverage change from 1996 to 2004 based on remote sensing images. The main conclusions are listed as follows. First, the areas of cultivated land, woodland, grassland and unused land decreased during the period, while the area of construction land and water area increased. The change rate of construction...
In this study, using "3S" techniques and partial correlation coefficients analysis, the spatial pattern and the factors of urban green spaces (UGS) in Hong Kong were analyzed in detail. Results indicate that there are many chances to improve the current conditions of UGS especially in the less densely place. The positive roles of PD and BD indicate that the organization and distribution...
Xinjiang has experienced considerable urban growth in the past sixty years, especially since the implementation of socio-economic reforms in 1978. When Xinjiang was founded as a Uygur Autonomous Region in 1955, there were only three cities with an urban population of 870 thousand, while in 2008 it had 21 cities with a total urban population with 8.45 million. Such an urban growth is attributed to...
The cities and Towns along the Jialing River can be categorized into 9 spatial patterns: top-outside, top-inside, heart, neck, waist-inside, waist-outside, twins, straight and intersection. Each pattern has its own advantages and disadvantages. Analysis on 95 cities and Towns in the mainstream of Jialing River shows that the dominant spatial patterns are top-outside, straight, and intersection. Optimal...
Land use change (LUC) model is fundamental in decision making process for regional sustainable development. It is practically important to analyze LUC in rapidly urbanizing region, such as Panyu District of Guangzhou, China, where a fast economy development makes it necessary to study the rule of urban land use change. Taking time-spatial land use change as the key point, a case study is carried out...
Based on the remote sensing image interpretation data of land use of Ningjin county in 2008, using the county and township scale as the basic measuring and calculating unit, through the calculation of fractal dimension of cultivated land, garden and residential site which belong to this county and all its towns, the results can be get. The result shows that, within unitscale of county, the fractal...
The application of GIS in regional studies has been an increasingly active area of research in recent years. The core issues include spatial statistics and the visualization of spatial data. In this paper, we discussed some exploratory approaches in identifying the urban center-periphery areas growth patterns using spatial statistics and GIS visual techniques. Some traditional spatial statistics and...
Soil organic matter (SOM) is an essential and dynamic variable in terrestrial ecosystem. This study used a method for mapping its spatial distribution by remote sensing technique. An image observed by Landsat 5 was used to estimate the spatial pattern of surface SOM in a town scale. The results showed that the concentration of surface SOM in study Jianshe town had a negative correlation (r =0.51,...
The spatial distribution of commercial service has significant importance for land management and urban planning. This paper attempts to discuss the spatial pattern of the commercial service at a general/city scale based on the voronoi model which is a powerful tool for the proximity analysis in GIS. Firstly, the commercial parcels are assigned to particles enduring their commercial function so as...
Rapid economic development, combined with tremendous population growth and migration from rural areas, has resulted in a dramatic urbanization in the Yangtze River Delta over the last three decades. In order to develop a more quantitative understanding of urbanization trajectory in the Yangtze Delta from the late 1980s to 2005, the time-series national land cover / land-use database (NLCD), interpreted...
By gradient analysis of landscape elements using remote sensing, this paper studied the spatial pattern of urbanization of Shijiazhuang, Hebei Province, China. Several landscape indices and class level were calculated in Fragstats with a moving window on two land use maps derived from remote sensing images along two transects of 64 km times 6 km, 66 km times 6 km wide, respectively. The result showed...
Global climate changes are changing our ecosystem and therefore changing the spatial distributional pattern of plants and trees. In this paper, we examine and compare the two South African Acacia tree species: Acacia gerrardii var. gerrardii and Acacia tortilis subsp. Heteracantha, and look at how they change in terms of distribution in the future (2100). We used the PDEAR (partial differential equation...
Remote sensing of urban land surface temperatures (LSTs) has been conducted based largely on pixel-by-pixel correlation with land use and land cover (LULC) types. Few studies have examined the spatial variations of LST within land use zoning polygons, in spite of its significance on the knowledge of environmental implications or planning practices. This study aimed to analyze the spatial patterns...
