Urban waterfront area design partitioning method based on hydro-climate effect

Abstract

An urban waterfront area design partitioning method based on hydro-climate effect comprises the following steps: processing remote sensing image data by adopting ENVI software, and performing surfacetemperature inversion by adopting an atmospheric correction method; setting a multi-ring buffer area under a GIS platform, extracting the surface temperature average value of a target plot and each buffer area, and calculating the average cooling value of each buffer area; carrying out regression analysis on the average cooling value and the buffer area distance to obtain an effective cooling range of a water body, and defining a climate sensitive area; analyzing an urban ventilation gallery, identifying a regional wind environment, determining an air inlet or a cold island intersection of theurban ventilation gallery, and dividing a windward control region; and simulating and analyzing a wind environment through fluid calculation mechanical software, and defining a ventilation potentialarea capable of constructing an artificial ventilation gallery according to the wind speed grade. According to the urban waterfront area design partitioning method, hydro-climate effect characteristics and urban design elements are fully fused; climate design partitions are qualitatively and quantitatively delimited; and a scientific auxiliary planning department constructs an urban waterfront area.

Description

technical field [0001] The invention relates to the application field of urban climate environment, in particular to a design partition method of urban waterfront area based on water body climate effect. Background technique [0002] The relationship between urban design and urban climate environment is one of the important research directions for the sustainable development of urban construction and ecological environment. Among them, the waterfront area is a special ecological area in the city. Due to the climate effect of the water body, the wind, heat, and humidity environment in the area change. Waterfront areas often become people's favorite outdoor leisure areas because of their open water surface space. Through the design and guidance of climate elements in waterfront areas, people and the environment can develop in a more harmonious and balanced manner.
