Topsoil Stripping Optimized Utilization Research

It is a major measure to protect the special black soil resources and improve the quality of new cultivated land in Jilin Province.It is the internal requirement of firmly maintaining the red line of 8295 mu of cultivated land and guaranteeing national food security in Jilin Province.Construction of new rural areas,to strengthen the protection of arable land,improve the quality of supplementary arable land,stable grain production an important starting point.To carry out the work of stripping soil is "very cherish,rational use of land and effective protection of arable land," the basic national policy of the firm implementation.This paper is based on the analysis of the topsoil stripping process and the post-stripping topsoil in the process of the project construction of the China-DPRK Ji an city and the Manpucity River Bridge,and the best design scheme and topsoil placement method can be obtained.Through the stripping of the soil can be scarce black soil protection,and then use the same time to ease the contradiction between China's land supply and demand of tension,while increasing the number of arable land to improve the quality of arable land,its significance is very far-reaching.This paper is divided into five parts to interpret the topsoil stripping studyThe first part mainly by understanding its research background,domestic and foreign in view of the development history of topsoil stripping,etc.,to establish the research target,research content,summed up the existing land reclamation project,the problems existing in the practice of topsoil stripping.The importance and necessity of explaining land reclamation and the stripping of surface soil.Roots in the second part through the analysis of the study area overall planning,through to the permanent land area in the study area soil type,soil texture,on-the-spot investigation,and combined with the feature of the study area is located the geographical position,topography,rainfall condition and social economic conditions,etc.,have a detailed understanding and the utilization of land reclamation in the study area.The third section evaluates the research area,makes a divestment evaluation route,builds the regional evaluation index system,and makes the most reasonable evaluation plan.Fourth part determine the thickness of this research area scope of topsoil stripping,stripping,stripping quantity and storage of conservation,rural farmlandtopsoil optimized as a case in this paper,how to optimize the topsoil stripping process,so as to make profits,farmers income,thus achieve the economical and intensive utilization of land,realize the maximization of economic benefits,ecological benefits and social benefits,overburden stripping of scientific research and service to the nation.The fifth part summarizes the problems and solutions that exist in the real world.Topsoil stripping of safeguard measures,clear in the topsoil stripping activities of the government,enterprises,individuals and other related duties and obligations,establish a perfect management system and measures,is the legal requirement of topsoil stripping activity standardization,to implement the topsoil stripping task,to our country for project specific implementation measures of the overburden stripping plays a profound significance.
