Problems solved by technology

Soil quality evaluation methods have received widespread attention, and many studies have been carried out on soil fertility evaluation and cultivated land quality evaluation. However, there are few studies on the evaluation methods and indicators of cultivated land quality in urban relocation sites.
There are many factors affecting the soil in the relocation site, and their respective contributions vary greatly. 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

[0047] The test site of this embodiment is selected in Shanghai Sanlin Greenland, and the first-class land is selected as the test site, and the quality of the test site is evaluated, and the specific items and corresponding weights of the evaluation index are determined as described in Table 1, and the values ​​of each evaluation index are measured. data to establish a comprehensive soil quality index model:

[0048]

[0049] Among them, Ai is the membership degree of each project layer, reflecting the pros and cons of each evaluation factor, Wi is the weight of each evaluation factor, reflecting the importance of each evaluation factor, (Ai) Wi It reflects the contribution rate of each evaluation soil quality factor to the rapid greening effect of the urban relocation site, and the multiplication operation reflects the interaction between each evaluation factor (the law of minimum factor limitation). The F value is calculated. When F≥0.6, the soil quality is judged as fir...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that second-class grounds are selected as test points.

Embodiment 3

[0053] The difference between this embodiment and embodiment 1 is that a second-class place is selected as the test point, and the test point is different from embodiment 2.

Abstract

The invention discloses an urban relocation land rapid greening soil quality evaluation method. The method comprises the following steps: (1) screening evaluation indexes; (2) performing parameter standardization of the evaluation indexes; (3) determining the weight of each evaluation index; and (4) performing evaluation by multi-index experience weight comprehensive analysis. According to the invention, an evaluation method is established by screening the indexes of relocation quality evaluation, evaluation indexes such as soil layer thickness, pH value, underground water level and drainage capacity are utilized to quickly obtain an evaluation result of soil quality of a relocation land, scientific guide is provided for the greening difficulty degree and the improvement method of the relocation land, and thus, directional cultivation and accurate greening of the soil quality of the urban relocation land are achieved.

Description

technical field [0001] The invention relates to the technical field of soil evaluation, in particular to a soil quality evaluation method for rapid greening 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 soil has...
