Evaluation Of Economy-Society-Land-Structure Changes And Development Of Erhai Basin

With the development of society,population growth and improving living standards,the relationship between economic and social structure and the land area are more closely,regional land use structure change research,for the realization of regional economic and social development and coordination of land use structure is significant.In this paper,Erhai basin as a research object,analyze the economic and social development and the Erhai Lake watershed land use status,with its own positioning and development Erhai basin,considering the appropriate factors,primarily research 2005,2014 two different periods of land use changes in economic and social data,established economic Erhai basin area-society-land index system evaluation of Harmonious development.According to the index data Erhai basin using entropy method to determine the weight of the different index system weight to the 2005-2014 period,this period of economic Erhai basin Society-Land coordinated development,results of the evaluation will help us to a better understanding of the relationship between the Erhai Lake Basin economic and social development and land uses.Integrated full economic and social use and land Erhai Lake Watershed Evaluation theory and practice,and come to the following conclusions:(1)On the Erhai Lake watershed land use change analysis,the area of arable land,forest and grassland are less and less,and the more the greater the construction area.Various types of land,the area of arable land is the largest reduction.Spatial pattern of land for construction to expand the overall trend showing a substantial increase in the area.Area of woodland and grassland,although also continued to decline,but the rate of decrease is not large.Dynamic changes of the waters is not very obvious.(2)2005-2014 Economic development indicators Erhai basin evaluation value increasing,indicating the level of economic development and constantly improve Erhai Lake Basin and social progress indicators Erhai basin evaluation value increasing,indicating growing social develpopment Erhai basin well,the structure of land indicator Erhai basin evaluation value increasing,showing the Erhai land use structure gradually reasonable.(3)The economy of Erhai basin with the coordination degree analysis showed that the coordination degree is rising,the economy-society-land is a serious imbalance in 2005,and in 2014 for good coordination,showing that the economy society coordinated development of Erhai basin structure continues to increase.
