Study On Potential Evaluation Of Urban Land Intensive Use Based On RS

The land is one of non-renewable resources, and the economical development has huge demand to the land. Especially our country is being in the economical development and the urbanized advancement acceleration period now. She has many people but little land, under the land resource supplies limited condition, it becomes the sustainable development on maintains the essential farming quantity, and must reasonably satisfy the urbanization use at the same time. Currently, it has prominent contradictory in the urban development and construction use to take up land high-speedily. It has Massive facts indicates that to tap new resources and economize on expense and uses the land intensively is the way to solve the problem. Meanwhile, the economic growth form is radical changing from extensive to intensive. It is the harmonious development of economy and society, and the sustainable development of environment and resource in the market economy condition. Therefore, it is very important to study on potential evaluation of urban land intensive use, not only in favor of the protection land resource, the urban development and the city land reasonable disposition, but also on the economical optimization growth way.This thesis studies the theories of urban land intensive use, and the theory, methods, index system and standards of urban land intensive use and potential evaluation. Case study of Shijiazhuang city, it takes the apply study on Potential evaluation of urban land intensive use base on RS, and analyses the evaluation result and gives Countermeasures and suggests at the end.1. The urban land use intensification potential evaluating mostly used the actuality land using map and cadastres in the past. It is weak on timeliness, possibly on mistake and less practicability. This thesis bases on RS and the integration basic data such as the nation economy and community development planning, the land using planning, the urban planning, the cadastre of urban and so on, which makes the2. It forms the index system and standards of urban land intensive use and potential evaluation base on RS. It evaluates the urban land intensive use potential of Shijiazhuang city and Qiaodong district for the first time. And the evaluation result accords with the fact.3. It applies the artificial neural network (ANN) in the urban land intensive use andpotential evaluation for the first time. ANN has the self-study function, and avoids the effect factors of human.4. The application of high ground resolution RS data, the image processing and the acquirement of information, which has technology advantage in the function area partition and evaluate unit selection of urban land intensive use and potential evaluation.5. It evaluates the urban land intensive use potential of Shijiazhuang city and Qiaodong district. The result and suggest offer the basis of the urban land use macro regulation and land resource optimal arrangement to the government of HeBei province and Shijiazhaung city, and the department of land resource management and city planning.
