Problems solved by technology

Soil quality evaluation and obstacle factor analysis have received widespread attention, and many studies have been carried out on soil fertility evaluation and cultivated land quality evaluation, but there are few studies on evaluation methods and indicators of urban relocation sites
There are many soil obstacle factors in the relocation site, the degree of obstacle is large, and the soil heterogeneity of each site unit is strong, which is quite different from the quality evaluation and obstacle factor evaluation of farmland soil

Embodiment 1

[0143] Utilize the evaluation method provided by the present invention to carry out the greening obstacle degree evaluation to the greening promenade relocation site on both banks of the Huangpu River:

[0144]

[0145]

[0146] Select 5 relocated plots for investigation and greening obstacle evaluation, the details are as follows:

[0147] Among them, 1 point is a severe obstacle, 2 points are a moderate obstacle, and 2 points are a mild obstacle. After measuring the plant height and stem thickness of trees, grasslands, etc. at each point for 3-5 years, it was found that:

[0148] In severe obstacles, the lawn is sparse, the trees grow slowly, the trees are weak, and the stems are thick and thin. It is necessary to transform the upper layer of non-soil and replace it with mixed soil and then improve it for landscaping;

[0149] The survey results of the land with moderate obstacles: the lawn is covered all over the ground, and the growth of trees is medium, which should...

Abstract

The invention belongs to the technical field of urban soil greening. The invention relates to the technical field of urban relocation, and discloses an urban relocation land greening obstacle degree evaluation method, which comprises the following steps: determining evaluation indexes according to the actual situation of an urban relocation, establishing a target layer, a project layer and an index layer to form an evaluation system, and respectively carrying out weight setting on each item of the project layer and the index layer to more scientifically express the real effect of each item ofindexes; and aiming at different properties, quantities, units and the like in the index layer, standardizing the indexes by establishing a mathematical model, and enabling each index to be in the same mathematical system, so that standardized calculation is facilitated.

Description

technical field [0001] The invention relates to the technical field of urban soil greening, in particular to a method for evaluating the greening obstacle degree of 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 content. The afforestation of urban soi...
