Description
Technical field
Field is repaired the present invention relates to soil pollution to repair with computer software development field more particularly to a kind of reduction soil
The method and system that the extremely extra-high value of pollutant influences in multiple.
Background technology
In recent years, environmental problem caused by industrial pollution place is increasingly prominent, and human health and ecological environment are produced
Serious threat, and significantly affect the safe handling of soil and groundwater resources.With Industry Structure adjustment " move back two into
Three " iterative method of policy, industrial enterprise shuts down or transfers in succession in many cities, has left a large amount of industrial pollution place.
Place potential hazard can be identified in contaminated site evaluation based on risk, be that site management provides determining for science with reparation
Plan is supported, has been increasingly becoming the main means of contaminated site management and control at present.What China was promulgated in 2014《Contaminated site risk is commented
Estimate fire protection technology》(HJ 25.3-2014) provides foundation, but in specific work for the determining of contaminated site soil risk controlling value
For how to delimit soil remediation boundary according to identified reparation desired value and estimate that reparation amount still lacks science in journey practice
Property.It repairs boundary and delimit inaccurate, fixed too low or excessively high of earth volume to be repaired can cause repair to face environmental risk
Or economic loss.
Traditional repaired area determines that there are mainly two types of method one kind is to carry out repair surface based on sampled point control range
Long-pending calculating, this method practical application are relatively simple.It is fixed in reparation value, by dividing single sampled point
Analysis, contrasting detection value and reparation value, are determined whether sampled data is exceeded, are summed with single sampled point control range, and then
To total repair coverage.Another method is directly to carry out space interpolation to original sampling data, by the use of reparation value as threshold value,
And then delimit restoring area.However both methods all has some limitations, the former ignores pollution body attribute in space
On the characteristics of being consecutive variations, and the latter does not consider influence of the extra-high value in part to final mask then, therefore the region delimited is expanded
It is big or reduce practical repair coverage.
