Study On Land Use Forecast Of Fuyuan In Sanjiang Plain Based On Landscape Pattern Evolution

Fuyuan county is the key region of Sanjiang plain,the largest natural marsh distribution area in china.How to protect the precious wetland resources,promote the protection of wetland and the coordinated utilization of agricultural land is a major issue in the development of grain production.Based on the analysis of landscape pattern and land use prediction research is more common,but using a suitable prediction model and landscape evolution perspective analysis and forecasting results and explore the inherent laws in order to seek for the coordinated development of the land use is very scarce.Based on this,this paper studies the methods of land use simulation forecast and forecast data from the perspective of landscape evolution.Based in Fuyuan County,to determine the overall trend of the regional land use by calculating the relative index,and according to the relationship between the transformation of various land use types,discusses the evolution of the rules,and to the 2020 land use structure prediction,the prediction results according to the inherent law of change,so as to provide theoretical reference for land use planning the existing areas.Firstly,the land use structure in Fuyuan to change between 2010 in 2000 were judged by calculating the land dynamic degree,landscape patt ern index,characteristics of landscape pattern in Fuyuan county are described and analyzed.Secondly,on the basis of summarizing the changes as the change rule,according to the CA-Markov principle,changes of Fuyuan county land use scale will appear in the 2020 forecast and judgment,and analyze its related characteristics.Then,using the Gini coefficient method,input-output coefficient method and corresponding analysis method,analyze the system of transfer of various land use types at different time nodes,to determine the various types of land use in the past and future trend and mutual transfer rule,including the difficulty in the overall transformation different time points by showing and similarity.Finally,on the basis of this,this paper will compare the land use pattern of the useful planning and forecasting results in 2020,analyze the rationality of the relevant planning,and put forward policy recommendations.This paper predicts the pattern of land use in Sanjiang plain of Fuyuan County,at the same time the landscape evolution perspective and put forward a new method of land based on structural analysis,in the analysis of prediction results,the use of economics in the Gini coefficient calculation method,input-output method,correspondence analysis and other analytical methods for landscape in land use structure provides a new from the perspective of analysis method.The results from the method to the simulation and prediction of land treatment provides a practical way,to maintain the stability of ecological system to provide decision-making support and scientific basis for the rational use of land,and has an important guiding significance for the sustainable development of wetland.
