Plant database for heavy metal contaminated soil remediation

Abstract

The invention provides a plant database for heavy metal contaminated soil remediation, and belongs to the environmental protection field. The method comprises the following steps: screening and collecting hyperaccumulator information of a database to be established as comprehensively as possible to improve the screening capability; preparing to make a database as a background plant information base of required database acquisition information so as to make preparations for subsequent data calling; preparing a scheme and formulating a repair type, and according to different topographies and landforms, making a relatively detailed treatment scheme, and classifying; and producing a database, searching required data information according to the database, artificially screening, carrying out planting experiments and manual planting for increasing the planting efficiency, and meanwhile, correcting data regularly. By preparing the required database for retrieving the soil pollution treatment,retrieval service can be conveniently provided for follow-up governers in the later metal soil treatment process.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a plant database used for remediation of heavy metal polluted soil. Background technique [0002] In recent years, due to reasons such as economic development mode, unreasonable industrial structure and high pollutant discharge, the quality of soil environment in my country has been seriously affected. The 2014 National Soil Pollution Survey Bulletin issued by the Ministry of Environmental Protection shows that the overall soil environment in my country is not optimistic. Some areas have serious soil pollution, especially the problems of cultivated land and industrial and mining industries, and the pressure on the soil environment continues to increase. Among them, the heavy metal content in the soil exceeds the reasonable capacity of the soil, and diffuses into the plant and the adjacent ecosystem, hindering the growth of the plant and destroying the...
