Green capacity rate algorithm model method for urban and rural ecological planning

Abstract

The invention discloses a method for ecological partition by a green capacity rate model. The method comprises the following steps: in an object region, the composition, the distribution proportion and the area of a plurality of vegetation communities are surveyed; an average green capacity rate distributed for each community is calculated by referencing to a green capacity calculation model; the actual green capacity rate of a certain community is calculated by referencing to the distribution proportion of the community; the average green capacity or actual green capacity of all the vegetation communities in the object region is calculated by repeating the step S200 and step S300; and according to the green coverage requirements of different grades of partition, and the average green capacity rate and the green coverage ratio of the vegetation communities are multiplied to obtain the green capacity rate of the object region. According to the method for the ecological partition by the green capacity rate model disclosed by the invention, the green capacity rate is quantified, the existing defects that the green capacity rate cannot be calculated and the subjectivity is too strong are overcome, and plants can be scientifically and reasonably distributed to the object region.

Description

technical field [0001] The invention relates to a method for carrying out ecological division by using a green capacity rate model. Background technique [0002] In the existing urban green space system planning, the green area rate and green coverage rate are used to control urban construction. This controls the proportion of green space to a certain extent, but ignores the ecological benefits of different green spaces such as lawns, shrubs and trees, which cannot be generalized. In order to improve the ecological function of green space and constrain the connotation of green space, we propose a green capacity index system suitable for urban and rural ecological planning to guide urban ecological planning to pay attention to the ecological benefits of green space and rationally allocate trees, shrubs and grass communities. [0003] The green volume rate planning model is a spatial planning method that uses the leaf area index to reflect the ecological benefits of green spa...

Problems solved by technology

As for urban ecological planning, how to combine the current green quantity, scientifically plan the green quantity rate of plots as much as possible, and establish a green quantity rate index system to guide the design of urban green spaces has not yet been mentioned.
