Study On Suitability Of Land Reclamation For Temporary Land Use In Rural Areas

Highway industry in our country is in the period of continuous expansion,with the rapid development of the highway,the land environment is bound to be destroyed.Therefore,the land reclamation work is particularly important.And the basic work of land reclamation is to evaluate the suitability of land reclamation.At present our country to the temporary use of the highway land reclamation suitable evaluation research is relatively narrow,put forward the research methods suitable for the highway with no special temporary land suitability evaluation of land reclamation,resulting in inaccurate evaluation results,the land reclamation project has a certain blindness,which leads to the lack of basis of land reclamation planning.At present the highway temporary research of suitability evaluation of Land Reclamation.Based on the Fusong section of the Hegang to Dalian Expressway temporary land reclamation land as an example,starting from the characteristics of the study area,combined with relevant theoretical knowledge of land reclamation,the highway construction process because of pressure,digging and the destruction of the land study on suitability evaluation of land reclamation,initially formed a set of suitable highway temporary land reclamation suitability evaluation method and index system,the main research are as follows:First,through the analysis of the research status of evaluation and suitability of domestic and foreign land reclamation,and combining the temporary influence and affect the quality of land land damage factors,selection of land quality evaluation index,and on this basis to establish a temporary land reclamation highway land suitability evaluation index system,mainly from cultivated land,grassland,woodland three reclamation direction selection to determine the evaluation grade and grading standard evaluation index.Second,according to the land characteristics of the study area,the appropriate evaluation index system is selected,and the mathematical model is established by the combination of the limit condition method and the limit synthesis method.Third,the use of suitability evaluation model,based on the actual situation in Hegang to Dalian Fusong expressway,the paper carried on the research on suitability assessment of land reclamation,land reclamation suitability evaluation according to the results to determine the different types of land at the proper direction.Fourth,through the analysis of Fusong Heda highway is the actual situation,the land leveling,topsoil stripping and biochemical measures on the destruction of land comprehensive restoration,provide the basis for future work of land reclamation.
