Land use and land cover change (LUCC) plays an important role in the evolution of the global environment and sustainable development. Land use is related to natural geography and human actions, and the factors during some period are mainly studied in LUCC. Most researches are concerned about rural area but few about urban fringe area. In this paper, land use change in the outskirtsis studied, taking...
Urbanization is a kind of project system where everything lies within and the relationships among them, which could be group into matter, human and affair. The harmony among them is absolutely necessary for the co-sustainability. Herewith the 3 concepts of “Matter-human-affair” principles have been defined and the relationship between the “3 Principles' Harmony” discussed. Taking the research of urbanization...
Facing the global environmental problems and energy crisis, landscape architecture appeals for the sustainable landscape design. Environment, economics, equity, aesthetics, experience, and ethics are the connotations of the sustainable landscape design. Based on the study of the themes of the sustainable landscape design, this paper points out that in the context of rapid urbanization the sustainable...
From the perspective of "human", this study focuses on the feeling of people in a certain region about the waterfront environment, by combining with theories in landscape architecture, environmental psychology and other interdisciplines, in view of present situation of waterfront landscapes in the Yellow River Scenic Area of Zhengzhou City, tries to find new approaches for waterfront landscape...
The water-level-fluctuating zone (WLFZ) in the Three Gorges Reservoir (TGR) changes seasonally because of the special hydrological characteristics and agriculture practices. Rapid land use changes have taken place in the WLFZ of the TGR, which is affected by the functions and structures of the local environmental system directly or indirectly. Land use change analysis is very important for land planning...
The objective of this paper was to develop a complete suitability evaluation index system on brownfield redevelopment using a case study of the Former Huishan Pesticide Factory in Wuxi City, China. In this paper, the Extreme Condition Method, the Fuzzy Comprehensive Evaluation Method and the Analytic Hierarchy Process (AHP) were employed for the case study. The results indicated that (1) the suitability...
Based on the RS and statistics methods, the objective of this study is to ascertain the spatial differences of urban land cover conversion of regional land cover with the Landsat TM images of the years 1988 and 2007. This paper illustrates the spatial expansion process of urban land cover with fractal model. The result shows: the land cover types changed greatly during 1988 to 2007; the area of construction...
Land use change plays vital roles in regional, social and economic development. Based on three phases of NDVI and climate images acquired in 1982, 1990 and 1998, and fuzzy rule-based classification, this paper took China as a case study to analyze spatial change of land use by combining NDVI, Landscape indices and transformation matrix. The research results indicate that land use has grown more and...
Taking Yanchi County as a case study, the driving factors of desertification had been analyzed. The results show that the remarkable feature of desertification of Yanchi County is the landscape changing from grassland and farmland to desert. At the same time, the fragmentation of grassland landscape is increasing continually, while the farmland is linked up on space with the decreasing landscape fragmentation...
For the target of ecological restoration and landscape overall optimization, the study selects China Jingxi abandoned coal mines for typical cases, takes advantage of remote sensing data and GIS spatial information processing technology, through the method combing existing land-use planning, damage assessment of ecological environment and overall optimization of land resource using pattern, determines...
Taihu Lake basin is among the most developed regions in China, and changes in land use and land-cover change were distinct in last two decades. The rapid economic growth and lagged measures in pollution control have resulted in serious environmental problems in this region. Using Landsat satellite imagery of different periods (1985, 1995, 2000, and 2005), we achieved the land use data in Taihu Lake...
This article analyzes the threats of peasant's livelihood after losing land, and delimits the connotation of lost-land peasant's sustainable livelihood, finally, rebuilds the compensations of land expropriation based on sustainable livelihood. They are agricultural land prices/the payment of employment and development and the price of social security. It calculates the agricultural land prices by...
This paper used RS and GIS techniques analyzed the landscape structure and changes in Cheng-Yu Economic Zone during its rapid urbanization and discussed the primary driving factors by means of canonical correlation method. And comes to these conclusions: (1) Considering the human disturbance and landscape anti-disturbance in landscape classification, statistical analysis showed that farmland was the...
Human activities on land-use make the land-cover gradually change or transit. With the GIS/RS technique, the paper studies the ecosystem service values change in Qianjiang City which is begotten by land use change. The results shows that the ecosystem service values shows an upward trend, and the land use structure is more reasonable.
Responses of hydrologic process to human induced land use changes, which have affected a wide portion of China since last century, were evaluated with a coupled land surface-hydrology model. The main land use changes were assessed by the International Satellite Land Surface Climatology Project (ISLSCP) historic (1970) and potential land use types in the Huaihe River basin. The variations of flood...
Land use/cover change (LUCC) is a key aspect of global environment change and in a sense indicates the influence of human activities on natural environment. Regional case study is the core of LUCC research. Taking the Hotan river basin, an oasis area of the Tarim river origin basin, as an example, Supported by RS and GIS technology, this paper reconstructed LUCC patterns in three periods of 1960,...
In this paper, the author taking the geological problem of environment and occurred geological disasters evaluating objects, apply GIS HAP to evaluate three subsystems of rock environment, environmental soil, water environment which affect the quality of geological environment of Wuhan megalopolis. By analyzing the main factors which affect the subsystems, the author establishes subsystem hierarchy...
Satellite images are now used as the primary source of spatial information for land-use pattern analysis. In this paper, land-use information is extracted by the maximum likelihood classification (MLC) and neural network classification (NNC) method, which is a combinative methodology of automatic extraction and recognition of land-use in Beijing City from remote sensing data. The temporal and spatial...
With development of RS and GIS, research in land use is a hotspot at present. Using RS images in 1986 and 1996 as data source; synthesizing to carry on land use classification of Xian Tao city. The law of land use changes is: cultivated land area has been declining; woodland is in a little growing magnitude; water and unused land grow to the high trend. Comprehensive index of Xiantao land use increases...
To investigate the state and degradation degree of wetland ecosystem in Dagu River estuary, the comprehensive assessment index (CEI) method was employed. A set of assessment indicator system was established based on the pressure-state-response (PSR) model. In this study, wetland landscape pattern and some data was interpreted from Landsat-TM images in 2000 and 2003 for the subsequent ecosystem health...
