Urban planning method and system

Abstract

The invention relates to an urban planning method. The method comprises: S1, carrying out region division on an urban area of a to-be-detected city to obtain a plurality of to-be-detected areas; S2, collecting a plurality of infrared images and weather information of each of the plurality of to-be-detected areas as well as the temperature of a suburban area of the to-be-detected city in real time; S3, acquiring an heat island intensity of each to-be-detected area based on the plurality of to-be-detected areas and weather information of each to-be-detected area and the temperature of the suburban area and marking the to-be-detected area with the heat island intensity reaching a preset threshold as a key area; S4, analyzing the basic information and heat island intensity of the key area comprehensively to obtain an interaction relationship between the basic information and heat island intensity; and S5, determining an urban plan suggestion of the to-be-detected city based on the interaction relationship. The method and system have the following beneficial effects: the cost is low; the precision is high; and the operation becomes simple.

Description

technical field [0001] The invention relates to the field of urban heat island effect, in particular to an urban planning method and system. Background technique [0002] Since the energy crisis in the 1970s, developed countries in the world have begun to pay attention to this issue, and have successively introduced a series of systems and policies to promote green buildings. my country has successively issued two "Green Building Evaluation Standards". The first one was implemented in 2006, and the new evaluation standard was implemented in 2015. At the same time, the original standard was abolished. In the green building evaluation system, heat island intensity is used as an index of urban thermal environment evaluation. [0003] At present, there are two main methods for measuring the heat island effect: the field observation method, by observing the actual research object in the near surface, and obtaining direct local climate data from the measuring point; the remote se...

Problems solved by technology

[0004] There are two types of field observation methods: fixed observation and mobile observation, both of which can directly measure the air temperature. However, its disadvantages are: it requires more personnel to operate on site 24 hours a day, and is restricted by the density of distribution points and the number of flow routes, which affects the measurement accuracy and Measuring Data Synchronization

This type of method is more suitable for the study of urban or larger-scale heat island effects. For the study of urban heat island effects, the disadvantages of using these two platforms are: high cost, poor accuracy, and complicated operation
