Research On The Land Resource Optimal Allocating Model System At County Level Under New Era

This thesis from the angles of system engineering theory and method analyzes the characteristics of county-level land resource allocating system, on which it brings up the structure and function of county-level land resource allocating system. Then it uses operational research and math as tool to set up a model to analyze current status and existing problems of land resource use, a model to implement multi-targets dynamic programming of land resource use, and a model to estimate and select land resource allocating schemes with artificial neutral network so as to realize a model system of county-level land resource allocating system. Finally it takes the county area-WuMing as an example to carry out a practical research. It firstly analyzes the current status and existing problems of land use, then with the eyes on macro-level, middle-level and micro-level targets of land resource use, designs a land resource allocatingmodel system and the system gives several scientific and feasible schemes as outputs. So it proves that the land resource allocating system is a convenient, effective method and tool. The establishing of land resource allocating model system breaks a new way to land resource optimal allocating research, and it has important academic significance and practical value.As for methods in this paper, they have the following characteristics: firstly, from the view point of theories and methods of system engineering, the author makes deep analysis on structure, characteristics and function of system at county-level land resource allocating system; secondly, using MATLAB as platform, the author solves complex models with simple programs in MATLAB, for example the author sets up the artificial neural network and succeeds to estimate and select land allocating schemes on computer with MATLAB programming language.
