Suitable Conditions And Identification Techniques For Topsoil Stripping In Black Soil Zone Of Jilin Province

The black soil is difficult to recycle valuable nature resources given human by nature. But with the accelerated process of industrialization and urbanization and unreasonable use patterns, caused a huge loss and waste of black soil.At present, cultivated land reserve resources become more scarce and the contradiction between population and land more and more prominent in China, Black surface stripping, is an effective measure to protect the black land. Jilin black topsoil stripping began in the1980s and made many successful experiences after20years of practice and exploration, a leading position in the country.The paper makes black soil region in Jilin Province as the research back ground, combines with the region’s natural environment and socio-economic conditions, set up index system of suitable conditions for topsoil stripping,forms suitable conditions for the different types of topsoil stripping in Jilin black soil region, proposes identification techniques for topsoil stripping, with project demonstration area at Fork Town, YongJi County, Jilin Province as an example to field validation analysis. The main contents include the following four parts:The first part explaines the background of the research questions and significance of this study, describes the research situation at home and abroad, the relevant theoretical basis, introduce the main methods and routes used in this study.The second part of the regional status of the black soil region in Jilin Province, topsoil stripping applicable conditions index system, divided into the type of topsoil stripping, topsoil stripping of different types of the applicable conditions of applicable conditions for these topsoil stripping recognition technology introduction.The third section presents an overview of the Yongji County Town fork in the road project demonstration area, combined with the black soil region in Jilin Province topsoil stripping of the applicable conditions and recognition technology research, the project area topsoil stripping the applicable conditions and identification technology to verify the analysis.The fourth part presents the main content of this paper, draws several major conclusions, and topsoil stripping the applicable conditions and the recognition of the prospect.
