1. The invention provides a method for calculating a soil restoration target value of a construction land based on a trial algorithm, which is characterized in that the method combines the typical exposure behavior characteristics of a crowd (namely, the crowd is in a random activity state within a certain range in an exposure period) and the pollution characteristics of nonuniform space distribution of field pollutants, and takes a preliminary restoration target value calculated when the UCL value of the residual concentration of the pollutants in an exposure unit is not more than the preliminary restoration target value calculated under the condition of an acceptable risk level as a judgment basis, rather than the situation that the residual concentrations of all sampling points are all lower than the preliminary restoration target value calculated under the condition of the acceptable risk level. Therefore, the final repair target value calculated and determined in the mode is more scientific and objective, and can represent the exposure behavior characteristics of the human population in reality.
2. According to the method for calculating the soil restoration target value of the construction land based on the trial algorithm, the characteristic that the exposure behavior of people in the exposure unit is random is considered, the restoration target value of the unit is calculated and determined based on the UCL value of the residual concentration of the pollutants in the exposure unit, the conservatism of the calculation result of the traditional method is reduced, and the capital waste caused by excessive restoration of the land is avoided.
3. In the implementation process of the method, firstly, a typical crowd activity range and pollution distribution are combined to divide a pollution area in a field into a plurality of exposure units, and a UCL value and a corresponding restoration target value of pollution residual concentration in each exposure unit are calculated; this step has avoided regard as an exposure unit to carry out pollutant residual concentration UCL calculation in-process, and a large amount of low concentration monitoring points probably dilute the sample, lead to UCL value calculation result to be low, and then underestimate the drawback of pollutant residual risk. In addition, the lowest value of the repair target values calculated in all the exposed units in the field is finally defined as the final repair target value of the whole field in the method, so that the health of people is guaranteed.

Drawings
The present invention will be described in further detail with reference to the accompanying drawings.

Detailed Description
Generally, the crowd can move freely and randomly within a certain range. Therefore, people moving in the contaminated site should also move randomly within a certain range throughout the exposure period, and contact the contaminated soil with a concentration of the contaminant that fluctuates randomly due to the non-uniformity of the distribution of the contaminated space in the site, rather than a fixed concentration of the contaminated soil. Generally, the ultimate risk to the health of the population is the accumulation of exposure to the contaminants throughout the exposure cycle. Theoretically, this cumulative value can be determined by integrating the concentration of the contaminant in the soil exposed to the various exposure frequencies as a function of exposure time. However, practical work is limited by capital and the like, and only limited soil samples can be collected in potential exposure units to monitor contaminant concentrations. As an approximate processing method, UCL values of the pollutant monitoring concentrations in all limited sampling points in the exposure unit can be used as the contacted pollutant concentration in the whole exposure period of the crowd, and as long as the UCL values of the residual pollutant concentrations in the exposure unit after restoration do not exceed the initial restoration target value under the condition of the calculated acceptable risk level, the soil restoration in the exposure unit can be considered to be qualified. However, the UCL value is a statistical variable, and the calculation result is influenced by parameters such as sample capacity, coefficient of variation, variance, and the like. The method for calculating the restoration target value of the soil of the construction land based on the trial algorithm fully considers the characteristics of nonuniformity of a polluted space of the land, randomness of exposure behaviors of people and the like, has more scientific and reasonable calculation result, and overcomes the defects of the traditional restoration target value calculation method.

Step eight, comparing the residual concentration UCL value of the concerned pollutant calculated in the step seven with the initial repair target value PRG calculated in the step six; for example, UCL = PRG, the target value for the repair of the contaminant of interest in the exposure unit, RAG, is designated as a.

Therefore, the repair cost can be greatly reduced.
