Estimation Methods And Model Research Of The Urban Ecological Environment's Basic Functions With RS Technology

With the development of urbanization and industrialization, many problems are brought in to the society besides many profits, and the deterioration of the urban ecological environment becomes one of the problems we concern about . In the paper, remote sensing technology is used to estimate the urban ecological environment's basic function (one of the problems of researched urban ecological environment's basic function) quality within the outside line area of Shanghai. Firstly , according to the actuality of the urban ecological environment's basic function, estimation factors are acquired and a new estimation system suiting to the urban ecological environment's basic functions is built by the dint of lots of urban ecological environmental quality estimation system in and abroad. Then , a new estimation method and an estimation model (including single factor estimation model ,integration estimation model) are built in virtue of the analysis of estimation methods and estimation models in and abroad .And then ,remote sensing information is acquired taking the example of urban greenbelt and the water , and urban ecological environment basic information is acquired in virtue of remote sensing technology and the classification result veracity is analyzed which is the basis of urban classification image and the latter estimation . Finally , urban ecological environment basic function's remote sensing quality estimation is performed within shanghai urban outside line by the new building estimation method and model and the estimation results are analyzed combining the reviewing on the spot to validate the correctness of the estimation method and model. In a word, in this paper, the quality estimation method and model of the urban ecological environment basic function are researched by remote sensing technology, which abundantly empresses the application value of the remote sensing technology in the urban ecological environment inspecting estimation. And at the same time, an estimation method and an estimation model which are suit to the estimation of the urban ecological environment basic function are built, which is very important to the comprehensive boosting ecological urban building's referent management and the programming and supplying scientific data and technological supporting to the decision.
