Embodiment Construction

[0016] A method for monitoring oil pollution in soil by using above-ground biomass indicators of communities described in the embodiments of the present invention comprises the following steps:

[0017] 1) Establish soil total petroleum hydrocarbon content plant / vegetation characteristic parameter prediction model, including the following steps:

[0018] (a) Select sampling points: select 30 sampling points on the vegetation around the oil well, set up three quadrats with an area of ​​1m×1m for each sampling point, and the distance between each sampling point and the oil well is between 30-130m. The site has not been disturbed by humans, the vegetation has not been trampled, and there is no non-oil pollution threat at the sampling site;

[0019] (b) Determination of plant / vegetation characteristic parameters at sampling points: measure and calculate each plant / vegetation characteristic parameter in three 1m×1m quadrats at each sampling point; the selected parameters include th...

Abstract

The invention relates to a method for monitoring petroleum pollution in soil by utilizing community aboveground biomass indexes, belonging to the field of environmental pollution monitoring. The invention is realized by the following technical scheme: (1) establishing a plant/vegetation characteristic parameter forecasting model of total petroleum hydrocarbon content in the soil, which comprises the following steps: selecting a sampling point, measuring the plant/vegetation characteristic parameters of the sampling point, sampling the soil and measuring the total petroleum hydrocarbon content, and determining an optimal forecasting model of the total petroleum hydrocarbon content in the soil; and (2) computing the total petroleum hydrocarbon content in the soil of the monitoring point by utilizing the optimal forecasting model TPH=806.514-134.763ln(TBio), wherein TPH is the total petroleum hydrocarbon content in the soil, and the TBio is the total community aboveground biomass in the quadrat of which the area is 1m*1m. Compared with the traditional chemical analysis method of soil and plants, the invention has the advantages of simple and easy realization and low cost, can save a large amount of labor, financial resources and time and can realize the purpose of quickly monitoring the petroleum pollution in a large area.

Description

technical field [0001] The invention belongs to the field of environmental pollution monitoring, and in particular relates to monitoring oil pollution of soil in terrestrial ecosystems by using plant / vegetation characteristic parameters. Background technique [0002] Due to global oil production, transportation, processing and utilization, oil pollution has become a common and serious environmental problem. After oil enters the terrestrial ecosystem, it will not only have a great impact on the composition, structure and function of the terrestrial ecosystem, but also oil pollutants can be gradually enriched in animals and plants through the food chain, and finally enter the human body, endangering human health. [0003] More than three-quarters of the world's total annual output of more than 3 billion tons of crude oil is produced by onshore oil fields. Most of the crude oil produced in my country comes from onshore oil fields. Therefore, how to effectively monitor oil pol...
