Embodiment 1

[0055] Example 1. Microbial evaluation of salinization-petroleum-heavy metal compound polluted soil quality in the isolated island area of ​​Dongying. The soil to be tested was taken from the isolated island area of ​​Dongying City, Shandong Province (sampling point 1). The steps are as follows:

[0056] (1) Selected microbial index evaluation factors

[0057] Soil respiration intensity, catalase activity, urease activity and microbial biomass carbon were used as evaluation factors;

[0058] (2) Determine the weight of the microbial index evaluation factor (W i )

[0059] Determine the weight of soil respiration intensity, catalase activity, urease activity and microbial biomass carbon as 0.121, 0.423, 0.281, 0.175 respectively;

[0060] (3) Calculate the evaluation index (P i )

[0061] Put the soil to be tested and the control soil in flower pots, 500g in each pot, and cultivate for 40 days at 25°C with a light intensity of 5000xl at a constant temperature; the soil humi...

[0096] Example 2. Microbial evaluation of salinization-petroleum-heavy metal compound polluted soil quality in the isolated island area of ​​Dongying. The soil to be tested was taken from the isolated island area of ​​Dongying City, Shandong Province (sampling point 2). The steps are as follows:

[0097] (1) Selected microbial index evaluation factors

[0098] Soil respiration intensity, catalase activity, urease activity and microbial biomass carbon were used as evaluation factors;

[0100] Determine the weight of soil respiration intensity, catalase activity, urease activity and microbial biomass carbon as 0.121, 0.423, 0.281, 0.175 respectively;

[0101] (3) Calculate the evaluation index (P i )

[0102] Put the soil to be tested and the control soil in flowerpots, each containing 500g, and cultivate them at 28°C with a light intensity of 5000xl for 50 days at a constant temperature; the s...

Abstract

The invention relates to a microbiological indicator evaluation method for quality of salinization, petroleum and heavy metal combined contaminated soil. The method includes the steps of selecting a microbiological indicator evaluation factor, determining weight of the microbiological indicator evaluation factor, calculating an evaluation coefficient of the microbiological indicator evaluation factor, and determining environmental quality level of the soil. The method is applicable to accurately measuring most types of salinization, petroleum and heavy metal combined contaminated soils under different soil conditions. The microbiological indicator evaluation method for quality of salinization, petroleum and heavy metal combined contaminated soil has the advantages that the method is economical, simple and highly operable; the microbiological indicator evaluation factor has a background value or control value easy to measure; the microbiological indicator evaluation factor is flexible and reliable enough for salinization, petroleum and heavy metal combined contamination and is more stable than other evaluation factors.

Description

technical field [0001] The invention relates to a microbial index evaluation method for salinization-petroleum-heavy metal compound polluted soil quality, belonging to the technical field of environmental quality evaluation. Background technique [0002] Traditional soil evaluation methods such as the single index evaluation method only evaluate the pollution degree of a certain pollutant in the soil. This index is widely used in the evaluation of various environmental elements at present. The advantage of this method is that it takes the soil environmental quality standard as the basis. However, it only evaluates the single element of heavy metals in the soil and cannot reflect the comprehensive situation of soil pollution; the comprehensive evaluation method of fuzzy mathematics makes the soil pollution problem according to different classification standards, and establishes the membership function in the closed interval (0, 1) The method of evaluating the inner continuous...
