Cooling and humidifying plant community for urban parks

Abstract

The invention provides a cooling and humidifying plant community for urban parks. The cooling and humidifying plant community is characterized in that a whole pattern is of a geometric shape and the length-width ratio of the geometric shape ranges from (1 to 1) to (3 to 1); a road for people or / and vehicles to pass through is arranged in the pattern of the cooling and humidifying plant community; the cooling and humidifying plant community has the canopy density of 75 percent to 80 percent, the leaf area index of 3.8 to 5.0 and the unit-area tridimensional green biomass of 4.2m<3> to 5.5m<3>; the cooling and humidifying plant community is composed of large evergreen arbor trees, large deciduous arbor trees, small evergreen arbor trees, small deciduous arbor trees, evergreen bushes, deciduous bushes and lawns; the large evergreen arbor trees and the large deciduous arbor trees are scattered in the cooling and humidifying plant community in a relatively uniform manner; the evergreen bushes and the deciduous bushes are fully laid on the ground along two sides of the road and are planted on the ground in a belt shape; the lawns are laid on other naked ground surfaces except the road and the lawns are bluegrass. The cooling and humidifying plant community for the urban parks is suitable for cooling and humidifying the urban parks; compared with a naked land, the temperature can be reduced by 2 DEG C to 5 DEG C and the humidity can be increased by 2 percent to 15 percent.

Description

technical field [0001] The invention relates to a landscape plant community, in particular to a cooling and humidifying plant community for urban parks. The cooling and humidifying plant community utilizes the combination of arbor-shrub-grass plants to fully utilize the plant growth characteristics and increase the greenness of the local environment. quantity, enhance its ecological effect of cooling and humidification, and make the local environment of the park achieve the effect of cooling and humidification, and at the same time have a good landscape. The cooling and humidifying plant community of the present invention is especially suitable for the middle and lower reaches of the Yangtze River. Background technique [0002] With the acceleration of urbanization and the impact of global warming, the urban heat island effect is becoming more and more intense, and the scope of influence of the heat island effect is also expanding. The heat island effect not only affects the...

AI Technical Summary

Problems solved by technology

In recent years, park construction has focused on landscape effects, often ignoring ecological benefits such as cooling and humidification of plants, which has greatly reduced the comfort of the park

[0003] At present, there are many researches on the cooling and humidification effect of parks and landscape plants and human comfort at home and abroad, and a lot of experimental data and methods have been accumulated, but many data are about a certain plant community, or the overall cold island effect of the park, etc. or The specific landscape pattern is studied, but the cooling, humidification and combination effects of specific plants are not studied, and the guiding significance for the construction of the park and the use of plants is not strong.
