Study On The Spatial-Temporal Difference And Influences Of Human-Iand Iitensity In Ji’an City

As one of the core issues in the human geography,the human-land relationship is getting more and more attention from pubilc and academia with development in society and economy and the change of ecological environment.As a human activity for the acquisition of desired products and services,land use is one of the most basic humanland relationship.First of all,from the view of land use,this article construct quantitative evaluation model of human activity intensity,select a set of suitable evaluation index system of regional human activity intensity,analysis the change over time and spatial differences of human activity intensity,and then,by combining previous research results and the local actual,the human activity intensity in Ji’an city is divided into five grades,and elements and characteristics of the human-land relationship in each level area are described and analyzed,finally,using the method of correlation analysis and regression analysis to study the factors that affect the human activity intensity.The results show that from 2009 to 2016,the human activity intensity continued increase from 10.18% in 2009 to 10.72% in 2016,and the overall increase was small.At the county level,the human activity intensity has changed significantly such as jizhou district,qingyuan district and ji ’an county and the changes in other counties and cities were relatively small.From the view point of spatial,human activity intensity in Ji’an city is high in the middle and low on all sides.The holistic structure is stable,but it has a great internal differences and high degree of spatial agglomeration.The elements and characteristics of human-land relationship in five areas have similarities and diversity,for example,population density and urbanization rate declined from high to low type,economic development level also declined from high to low type.Another example is that land use structure are mainly on agricultural land,construction land is small,with the increase of human activity intensity,the proportion of construction land is increasing,and the reserve land resources are insufficient.Human activity has remarkable effect on the local original geographic environment and the government and residents needs to improve environmental protection and sustainable development.From the factors influencing the of human activities intensity,terrain,water resources,population,economy,transportation,urban and rural differences of it affected by the change and spatial distribution of human activity intensity and other factors have less effect.The influence factors will change with the development of local social and economy and technological,and the influence of humanistic factors will become more and more significant than others.This paper provides a useful way to study the human –land relationship and the harmonious development between regions in Ji’an city.
