With the interpretation and analysis of 1978, 1988, 1998 and 2008 remote sensing images, evolutionary process during different periods of Suaeda heteroptera and reed wetlands in Liaohe Delta was discussed. Results showed that, although areas of Suaeda heteroptera and reed wetlands during 1978–1988 were increased, their areas were abbreviated from 1978 to 2008 in the mass. The area degeneration of...
Evaluating the level and extent of urban land intensive use objectively can provide scientific basis for urban land resources reasonable allocation and the land sustainable utilization. This article takes Mudanjiang built-up area as total evaluate unit, takes Xian area, Dongan area, Yangming area, Aimin area as partition evaluate unit, obtain the land area of some kinds of the four central areas by...
Discusses the re-utilization of the riverside, comparing the differences between the regular design of riverside and ecological balance. Further summarizing the strategy of the old urban riverside ecological stability, according to the gathering of internal and external empirical research and methods of contrast and analysis: First, the antecedence measure of the river's ecological balance, including...
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 paper takes the land arrangement project of GuiHua Town Xian' An District as an example, mainly research on the impact on the ecological environment by the land arrangement projects. With 3S technology, aimed at extracting images from remote sensing information, the GIS-assisted spatial data analysis functions, an econlogical assessment model of land arrangement is formed on the basis of 3S technology.
This research simulated the urban growth scenarios of a mountain city of Chongqing, China through a CA-based model of SLEUTH. The fundamental data were four Landsat TM images of 1978, 1988, 1993, and 2001 which were utilized for generating maps of land use, road networks, and urbanized area. Three alternative development scenarios, including business as usual, compact city and decentralized concentration,...
As the best preserved inland canal in Taiwan, Tainan canal has witnessed the rise and fall of the city along with the Tainan people. Due to the industrial restructuring along the canal in the past years, its navigation function gradually declined and the areas adjacent fell into a recession. In order to revive the canal and revitalize the areas along it, the Tainan city government initiates a re-development...
Facing the monitoring demand to the progress of key project using remote sensing technology, the Beijing-Tianjin inter-city railway project (Beijing South Railway Station) was taken for example and the high resolution remote sensing image of 2005 (before project) and 2007 (in project) were used as data source. At first, we built land-use classification index system. Then land-use information of South...
Japan leads the world in green technology. With the expansion of the scale of land development and the higher level of civil Engineering Construction mechanization, Japan has already developed the appropriate technology to green land. Japanese government implements strict environmental protection measures. The concept of ecologically sustainable development take root in people's community. Many of...
The evaluation of land exploitation according to its capability is one of the most fundamental issues in sustainable development. For this purpose, selection of a suitable method is very crucial to consistent the results with fact. Hitherward different methods have been used for evaluation studies and talk about the effectiveness of each method. In this study, the irrigated agricultural site selection...
China's arable land resource is scarce. To protect the arable land, China carries out a basic farmland protection system. Arable lands with best natural qualities, location conditions and larger areas are protected as basic land. It's specifically stipulated that the basic farmland should be determined in the general land use planning. A certain quality and quantity of basic farmland is not only a...
The veracity of land evaluation is tightly related to the reasonable weights of land evaluation factors. A new method is proposed for determining land evaluation factors by combining the subjective and objective weights based on rough sets mining theory in this paper. Objective weight is obtained based on the rough sets theory. On the basis of the experience knowledge and practical applications, decision-makers...
Rural highway construction is the important content of building a new countryside. The rapid development of rural highways construction means that a large demand for land resources. In the analysis of the basis of the status and trends of land use for construction of rural highways, this paper summed up the characteristics and main problems in land use of construction of rural highways, according...
Research on characteristics of expressway so that the space planning service area a reasonable scale appropriate to use both to meet the clients needs and save investment at the same time, reducing the land, protecting the environment. Help to optimize the expressway traffic environment, improve operational efficiency and social benefits of expressway.
Discussing the spatial distribution of industrial land intensive use has become a new international researching area now. This work sets the Wuhan metropolitan areas as the researching example, based on widely collecting the industrial land use data of 42 industrial development parks in the researching area. It built an industrial land intensive use appraisal system which includes 16 indexes, such...
From a spatial view, the rural-urban fringe zones are rapidly change areas near big cities. It is evident that the road construction and improvement played an important role in these processes. Quantifying the landscape change of main road on land use is important to elucidate effects in future. We chose an expressway near Beijing as a case, calculated and compared the land use change in 1991 and...
Following the extensive urbanization, more and more people swarm into cities. Demands for urban infrastructure and land use, therefore, will change rapidly and drastically, and most urban planning should be regulated or remade. Under the new situation, location of public service facility should be paid more attention to, while the general software platform could not assist it well. Therefore, a new...
Based on SLEUTH urban growth model and Technology of GIS and RS, the process of urban growth of Xinxiang City from 1989 to 2009 was simulated, and the process of urban growth from 2010 to 2050 was predicted. The result illuminated that SLEUTH model had a credible accuracy, and it could well describe Xinxiang city's extension to the southeast as a whole during 20-year period. The city's area increased...
Rapid urbanization processes have been primarily attributed to tremendous changes in the exploitation manner and intensity of urban land use. The limited and nonrenewable characteristics of urban land resources prompted to develop and utilize urban land use rationally, which would push the sustainable development of urban land use. The evaluation of urban land use suitability contributed to identify...
Construction land location advantages and agricultural land suitability evaluation are the most important basis for land use decision in urban region. This article focuses studying on Hangzhou case, an urban region with very rapid construction expansion. In this study, GIS is using for spatial analysis and mapping, while K-Means Clustering (KMC) and BPNN for attribute data process. Factors including...
