Obviously, the urban planning is the precondition and the base of urban land development and urban construction. So the level of urban planning will affect the development degree of urban.
Consequently, the quality of urban ecological environment and the environmental capacity of pollution in Guangzhou have been decreasing. That is the main barrier to the sustainable development of the city. Some measures to coordinate urban construction with ecological environment are suggested: improve the urban spacial structure, enhance afforestation of the city, and increase the area of waters.
Starting from the areas of constituting the digit standards of geographic information metadata, designing metadata warehouse, developing metadata operation tools and building up metadata warehouse in Shanghai urban construction.
Chapter Five has further described the construction and implementation of database of the geographic spatial information metadata in Shanghai urban construction, one of the information sharing tools in "digital Shanghai". Through the discussion and study on its theory, technology and implementation of a "digital city" in above-mentioned chapters, the paper has provided an overall methodology, a structural framework, an implementing approach
Conference on problems of urban construction in thegas-bearing regions of the Tyumen' province
Urban construction activity also disrupted the inflow stream bed and facilitated transport of clay into the lake to generate non-rhythmic banding in the lake's deep hole.
According to the features of abundant wetland in Wuhan City, we suggested that protection of wetland landscape should cooperate with urban construction, which means wetland should become important part of urban landscape.
The reasons for these results were mainly because of urban construction.
Then, transformation probabilities of wetland landscapes into non-wetland landscapes were calculated based on Markov Model, and on these grounds the relationship between changes of wetland landscape pattern and urban construction was analyzed.
The structure of information system corresponding to a complicated system, which composed of population, resource, environment and economics, is multi-level, respectively applied to national macro decision-making, regional development and urban construction. There are different emphasis on spatial or statistical pattern for different level system. The progress of developing resource information system which started late in China varies in different fields, and current systems are incomplete, of which the...
The structure of information system corresponding to a complicated system, which composed of population, resource, environment and economics, is multi-level, respectively applied to national macro decision-making, regional development and urban construction. There are different emphasis on spatial or statistical pattern for different level system. The progress of developing resource information system which started late in China varies in different fields, and current systems are incomplete, of which the population database lacks spatial pattern, economic database is statistical pattern, and ocean environment and resource information system only acts as a literature retrieval system. The resource information system should not be limited to retriving and inquiring, but be expanded to the functions of high-level analysis, simulating and forecasting. Recently, several software systems can answer some major problems in decision-making procedure, such as the reliability of data, the capacity of resource, suitability of environment, the accessibility of transportation, the feasibility of engineering and the stabability of production, and the work developing system dynamic model and expert system are being done.
This paper introduces briefly progress in research of urban geomorphology at home and abroad; and mainly deals with principal contents: relations between distribution of cities, urban disasters and pattern of landforms in China; effects of gcomorphological environment on urban construction and development, artificial agents and manmade landforms in cities, theories and methods of research of urban geomorphology and other problems.
China has vast territory and various geomofphic types. Based.on the relationship between the geornorphic ' structure and urbanization, China may be divided into three regions, i. e. High plateau and mountains in the southwestern China; Plateau and basins in the northwestern China; and Great plain and hilly land in the eastern China. The cities of China are varied, and the urban geomorphic sites are different. The cities of China are mostly distributed at the confluences of the rivers, river-terrace plains, the...
China has vast territory and various geomofphic types. Based.on the relationship between the geornorphic ' structure and urbanization, China may be divided into three regions, i. e. High plateau and mountains in the southwestern China; Plateau and basins in the northwestern China; and Great plain and hilly land in the eastern China. The cities of China are varied, and the urban geomorphic sites are different. The cities of China are mostly distributed at the confluences of the rivers, river-terrace plains, the boundary between two big geomorphic units and seasides and islands. The present geomorphic processes have had great effects on the urban construction and caused the disasters, such as flood, subsidence, landslide, debris flow. etc. Therefore, it is important to understand the evolutive laws of geomorphic processes in order to prevent and control the disasters.
