The Waterfront Space Night Light Environmental Quality Comprehensive Assessment Research For Funan River In Chengdu

As to the question of how to evaluate the modern urban waterfront space night light environment quality, there is only the general qualitative description, no specific quantitative indicators current standards and regulations in the standard and regulation of our country. So the execution has certain capriciousness, waterfront space night light environment quality has no strict evaluation basis and evaluation standard, so it is often difficult to fully meet the requirements, and leads to the waterfront space night light environment quality of some parts being bad, influencing seriously the comfort of the night tourists and city image, etc. Therefore, it is an urgent need to find a scientific and rational urban waterfront space night light environment evaluation method. As for this, the article is on the basis of the status quo and existing problems combining with the urban waterfront space night light environment, and puts forward the urban waterfront space night light environmental quality comprehensive assessment research topic.Firstly, the article expounds the concept of waterfront space night light environment and characteristics of waterfront space and related research progress on light environment at home and abroad. Besides, it is classified by the combination of chengdu city waterfront space unique geographical environment, as well as its related with water in the process of historical development form the unique culture of chengdu city, and analyze its present situation and characteristics. Then take the waterfront space night light environment at home and abroad as the research object, and take advantage of the method of literature comparison waterfront space with night light environment related indicators group on the basis of establishing indicators and indicators of decomposition method to get an initial evaluation index, and then use the fuzzy Delphi method to screen these evaluation indexes, finally construct the waterfront space night light environment quality comprehensive evaluation index system. Finally, make chengdu funan river waterfront space night light environment quality comprehensive evaluation based on the analytic hierarchy process (AHP) of multilevel fuzzy comprehensive evaluation method, and the method was described in detail. Take the section from south gate bridge to Jiuyan bridge as an example for the waterfront space night light environmental quality comprehensive assessment research of Funan river in Chengdu.Through this research, the article established a three-level index, a total of37evaluation index of urban waterfront space night light environment quality comprehensive evaluation system. Through the construction of evaluation system and standard and formulation, the analytic hierarchy process (AHP) of multilevel fuzzy comprehensive evaluation method can be used to evaluate environmental quality of chengdu Funan river waterfront space night light. On the whole, comprehensive evaluation of the results is "good". It is mainly manifested in the waterfront space night light environment security, because it can satisfy the tourists sightseeing, night activities and personal safety requirements; with better comfort, visitors will be able to get a better aesthetic and psychological feeling in the process of tour; with better identity, tourists can easily identity things in the process of going through waterfront space, roads, entrance logo logo recognition, landscape elements, revetment, etc; But the economy is bad, the landscape lamps and lanterns are not chosen good, without choosing better lighting energy consumption and energy saving measures, the whole waterfront space night light environment has a large effect on plant growth. Although some shortages exist in the night light for urban waterfront space environment quality comprehensive evaluation process, it can provide some evaluation methods for meaningful reference in the future through the preliminary study of the evaluation.
