The system and method can realize city block green space planning reasonably, and the purpose of retarding a source of a city block heat island effect is achieved. The method comprises the following steps: S1) constructing a block planning reference model of a preset block in the ENVI-met, running the ENVI-met to obtain thermal environment data simulation result of the block; S2) changing a green space structure of the reference model to obtain a situation model, and running the ENVI-met to obtain thermal environment data simulation result of the block; S3) determining an optimal heat island slowing green space planning scheme of the block according to the thermal environment data simulation result of the block, wherein the thermal environment data simulation result comprises a temperature simulation result; and S4) carrying out green space planning on the block according to the optimal heat island slowing green space planning scheme.

Description

technical field [0001] The invention relates to the field of environmental science and technology, in particular to an ENVI-met-based method and system for urban block green space planning. Background technique [0002] The block heat island effect is a manifestation of the urban heat island effect on a small spatial scale. It is due to the dense building groups and artificial structures in the block that change the thermal properties of the underlying surface, supplemented by a large amount of human heat dissipation, resulting in the block A local climate phenomenon in which the internal temperature is higher than that of the surrounding area. As the basic unit of urban space, the block area is the most active place for urban residents. The deteriorating heat island effect has affected the climate, hydrology, air quality, and soil physical and chemical properties in the block, seriously restricting the ecological environment and residents' health in the block. How to effec...

Problems solved by technology

With the help of remote sensing and on-site monitoring methods, domestic and foreign scholars have carried out quantitative analysis of urban thermal environment and green space data by using landscape ecology, statistics and other related technical methods, verified the macroscopic phenomenon of green space mitigation of heat island effect, and described green space slowing down. The inherent properties of the heat island effect explored the cooling effect of the green space and the degree of influence on the surrounding thermal environment. The relevant conclusions have certain guiding significance for the planning and construction of the urban green space landscape at the macro level, but most of them still stay at the overall level. There is a lack of practicality in the design of landscape greening schemes based on the block as the standard
