Studies On The Change Trend And Optimizing Strategy Of Land Use Structure Of Liaoning Province

The change of land use structure is one of the hottest topics in global research.At present,our county's land structure is in a more extensive phase.It is good to achieve rapid economic growth as well as ensure sustainable utilization of land resources from the perspective of social econony to study the change of land "use structure.By researching the structure of land use for Liaoning Province,this article aims to get a better understanding of the change of the level and quantity of land use structure,reveals the basic rule of land use structure change,analyzes its change driving mechanism,forecast the land use structure,optimizing the adjustment and providing some references for the optimal allocation of land resources,so as to realize the reasonable and effective use of limited land resources.This paper analyses the land use structure of Liaoning Province from 1996 to 2013,reveals its changing characters in the last 18 years.The cause of changes of land use structure information entropy in Liaoning Province for 16 years is also analysed.Based on the analysis of land use structure evolution trajectory in Liaoning province,the author studies the driving mechanism of land use structure change in Liaoning Province by using the method of combining empirical analysis with normative analysis.And it mainly uses quantitative analysis of social-economic driving forces,accompanied by the qualitative analysis of natural driving forces and government regulation policy driving force.In addition,the author uses principal component analysis to identify the driving force factors on land use structure play an important role in the evolution of the land use structure.In addition,the author introduces the basic theory of system dynamics and multi-objective programming,and studies the feasibility of SD-MOP Integration Model to propose a new method for the optimization of land use in Liaoning province as the research example based on SD-MOP integration model Respectively,the conduct of model,the estimation of parameter and the identification of the sensitivity factors,and simulation running and the optimization of the model are studied carefully.According to the results of the analysis of land use structure optimization of Liaoning province,it provides a reasonable optimization scheme.Finally,according to the analysis and study of land use in Liaoning Province,the author puts forward the land use structure optimization adjustment of the relevant policies and suggestions of land use in Liaoning Province.
