Theory and Method Research in Land Systems Engineering

According to the continuous reinforcement of the degree and intensity of the humanity to the land development use,the relationship between person and land is more and more tense.The methods of the systems engineering are introduced to the land system,that is,the land systems engineering.The land systems engineering is sep up from the angle of the integrity and the systematization,finally realizing the comprehensive benefit optimization of the land system.The article proposes the elementary theory frame of the land systems engineering and elaborates the job steps and method systems of the land systems engineering.The land systems engineering provides the basic of strategic decision for the plan,the development,the use,the renovation,the management,the protection and the appraisal of the land which has the vital signification to coordinate the relationship between person and land and to realize the land sustainable use.
