【摘要】：针对人口拥挤、交通拥堵、环境污染、住房困难等一系列"城市病"问题,为了客观、定量评估城市现状,找到"城市病"根源,本文面向城市区域评估,利用空间大数据全面、客观、准确的特点,对城市进行全方位的评估,从人口、资源、环境、住房、公共设施、道路交通、经济发展及城市安全等多方面为治理"城市病"提供基础数据。本文从城市区域评估的内涵入手,设计了城市区域评估的总体流程,建立了全面的评估体系,并对实现城市区域评估的关键技术进行了阐述。通过城市区域评估的方式,对城市现状客观扫描,将使"城市病"的病重程度得到客观度量,是根治"城市病"的首要条件。
[Abstract]:In view of a series of "urban diseases", such as population congestion, traffic congestion, environmental pollution, housing difficulties and so on, in order to objectively and quantitatively evaluate the present situation of cities and find out the root causes of "urban diseases", this paper aims at the evaluation of urban areas. The comprehensive, objective and accurate characteristics of spatial big data are used to evaluate the city from population, resources, environment, housing, public facilities, road traffic, Economic development and urban safety and other aspects for the treatment of "urban disease" to provide basic data. Starting with the connotation of urban regional assessment, this paper designs the overall process of urban regional assessment, establishes a comprehensive evaluation system, and expounds the key technologies for realizing urban regional assessment. Through the evaluation of urban areas, the objective scanning of the present situation of cities will make the degree of disease of "urban diseases" be objectively measured, which is the primary condition for radical cure of "urban diseases".
