Greening construction index model method for urban and rural ecological planning

Abstract

The invention discloses an ecological division method by utilizing a greening construction index model. The ecological division method comprises the following steps of: investigating the composition, the allocation ratio and the area of a plurality of vegetation communities in a target area; calculating the average green capacity rate allocated for each community by referring to a green quantity calculation model; on the basis of calculating the green quantity of a single plant, calculating the planned greening value in a certain greenbelt range by referring to the community allocation ratio; calculating the green quantity value or the real green quantity of the vegetational communities in each of the other greenbelts in an area; calculating the green capacity rate of the target area; calculating the total green quantity in the target area according to the conversion rate and the total green quantity of each greenbelt; and calculating the greening construction index of the target area. According to the ecological division method by utilizing the greening construction index model provided by the invention, the green capacity rate is calculated, so that defects that the conventional green capacity rate cannot be calculated and the subjectivity is too high are overcome; and the target area can be subjected to plant allocation scientifically and reasonably.

Description

technical field [0001] The invention relates to a method for carrying out ecological division by using a greening construction index 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 g...
