Method utilizing green quantity rate model for urban and rural ecological planning

Abstract

The invention discloses a method utilizing a green quantity rate model to perform ecological division. The method comprises the following steps: surveying formation, configuration proportions and areas of a plurality of plant communities in a target area; calculating an average green quantity rate of each community according to a green quantity calculating model; calculating a real green quantity rate of some community according to the community configuration proportions; repeating a step S200 and a step S300 to calculate average green quantity or real green quantity of all the plant communities in the target area; and according to different grade division green coverage requirements, enabling the average green quantity rate of the plant communities to be multiplied with a green coverage rate to obtain the green quantity rate of the target area. According to the method utilizing the green capacity rate model to perform ecological division, the green capacity rate is quantified, the shortcomings that an existing green quantity rate cannot be calculated and the subjectivity is too strong are overcome, and plant configuration can be performed to the target area scientifically and reasonably.

Description

technical field [0001] The invention relates to a method for carrying out ecological division by using a green quantity 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...
