The Research Of Human Settlement's Quality Evaluation Of City Community Based-on Remote Sensing

Along with the rapid development of growth of China's economy, the demand of Chinese towards residential living has risen to a level where people striving to have a high quality community on Human Settlements. With the fast development of housing, more and more problems have been discovered within these communities on human settlements. In result, It becomes an obvious issue between the people's need for better quality living and the current status of residential living.Human settlements quality covers a wide range of topics. It's a new research focus to evaluation the quality of the community on Human Settlements. Based on the theory of sciences of human settlements, this article probes the inner connotation of human settlements of residential community, analyses the important influencing factors of human settlements of residential community. Combined with the modern remote sensing technology advantages on extraction of objects from urban aerial images, this article sets up an index system of human settlements of residential community based-on Remote Sensing. This index system includes buildings, green land and population factors. Among the many indexes of the valuation system, this article uses the Analytic Hierarchy Process (AHP) by the calculation of the experts'judgment Matrix and consistency Test to give value of the indexes of the system. It's a new way to use remote sensing methods to obtain the indexes, not only in remote sensing application, but also in the environment assessment. The primary is the extraction of the green land and the shadow of the buildings.Last, this index system is put to use in an evaluation a project of residential community in a university. It uses the aerial image of the community and some static information to obtain the indexes. And we get a comprehensive evaluation of the residential community. Also, it tests the scientific quality of this index system of human settlements quality of residential community after the analysis of the result. And, we can know that the RS method is utility and timeliness.
