Evaluation Of City Living Quarters Living Environment

With the research on urban living environment, it as an index expression city sustainable development, can reflect the residents enjoy all of the resource convenience and equality, or not, and reflects the urban spatial distribution pattern very well. Actually habitat environment is the epitome of urban living environment, it is the key of measure the quality of living environment, and the key to effective prerequisite and foundation of other urban functions.This paper discusses the human environment from micro aspect based on the scale of residential of Guilin city. On the one hand, With the residential quarter position in urban for the study of spatial scope, the research contents are close to the residents, including convenience, life convenient, etc; On the other hand, to research residential area base on the micro content and index, reflect live comfort. Different from traditional research limitations, try to comprehensive use of GIS spatial analysis method and the urban planning analysis model, to explore how to resolve GIS spatial analysis technology and urban planning specific problem. For analysis and annotation habitat environment through the residential quarter, and using the mathematical model to analyze it, discusses how to make habitat environment academic turn to implement and operation.The evaluation result is:the qunshanhuayuan quarter weight 0.3369, the donganfengjing quarter weight 0.2359, the lanqiaoshengfei quarter weight 0.2182, the huguangshanse quarter weight 0.2092. The weight bingger, the living environment better. Find out the differences about living environment, analysis their facilities, environment etc. Not only for urban residential environment construction and scientific evaluation, but also for provide both comprehensive application theoretical and case reference. Its main contents include:Firstly, this paper is evaluate the entity unit of living environment, established the resource distribution and traffic network's mutual relationship of the residential area in the urban, with away from parks, schools, hospitals, and commercial center's distance as the index. Based on the theory of accessibility, using the GIS network analysis technology, construction the time zones, expression the spatial relationship as time distance between the two place, analysis using the resource convenience of each residential quarter.Secondly, for reasonable evaluation the quality of living environment, measure the construction of land use, reflect the ecological and the virescence of residential, with the plot ratio and virescence ratio as evaluation indexes. At the same time, will express sunshine time length of the sunshine duration and can reflect the building toward of the sunlight space as evaluation indexes. It must be pointed out, for reasonable express sunshine duration, analysis with the other various indexes convenient, proposed "the sunshine percentage" this impact factor, that is to say, take the sunshine duration calculation converted to the sunshine percentage. Each index is quantified values, more experience than described on the comparability.Lastly, evaluate the urban residential based on the Analytical Hierarchy Process, with parks, schools, hospitals, commercial center, plot ratio, greening rate, sunshine percentage, sunshine distance altogether as the evaluation indexes. Note that in the process of establishing judgment matrix are base ong each index summary data, and the structure of the matrix can reflect each index contain information intuitive, this evaluation calculation process is the special content of this paper. Finally, through combination weights of total sorting reflect differences in living environment, reduce the errors caused by subjective judgment. This paper comprehensively used GIS spatial analysis technology and the field of urban planning professional analysis model, from establish the evaluate indexes, partition the evaluate cell, distill the evaluate indexes to establish evaluate model process evaluate practice, has formed a set of relatively complete technical route and method of regional living environment.
