Embodiment 1

[0046] In the green corridors on both sides of the Huangpu River, survey 5 points, and measure the plant height and stem thickness of trees and grasslands at each point for 3-5 years (Table 4). The comprehensive score is calculated according to the various indicators of the soil before the reconstruction of the site (Table 5), and the accuracy of the evaluation can be obtained by comparing the comprehensive score with the current greening effect. :

Abstract

The invention belongs to the technical field of urban soil greening and discloses a quantitative evaluation index determination method for the rapid greening soil obstacle degree of an urban relocation land. A comprehensive evaluation system score of four indexes including non-soil-layer thickness, non-soil-layer position, non-soil-layer material attribute and ground drainage capacity is added besides conventional evaluation indexes, so that the comprehensive evaluation system score more matches the greening effect of the relocation land, and the soil obstacle degree of rapid greening of theurban relocation land is better evaluated.

Description

technical field [0001] The invention relates to the technical field of urban soil greening, in particular to a quantitative evaluation index determination method for rapid greening soil obstacles in urban relocation sites. Background technique [0002] Urban green space soil is the growth medium and nutrient supplier of urban garden plants, and an indispensable part of the urban ecosystem. It has certain ecological, environmental and economic functions, and is of great significance to urban planning and sustainable development. After more than 30 years of rapid urbanization in China, the role of landscaping in improving the living environment has received more and more attention. In the 2015 Central Urban Work Conference. It formally clarifies the transformation of urban development from extension and expansion to connotation improvement, and takes "vigorously carry out ecological restoration and make the city reproduce green water and green mountains" as an important conten...
