Analysis The Relationship Between Land Use Changes With Its Humanity Factors In Qinling

There is close contact between humanity factor and LUCC,LUCC reflects the impact of the direct and inherent influence from different humanity factor. Due to the influence of humanity factor,LUCC has certain internal relation with it.Through analyzing the relationship of them,it can reflect the influence process of humanity factor to LUCC,which provides theoretial basis for rational land use development and protection.With 2000、2005 and 2010 three periods of land use data and humanity factor data as data sources,used GIS and geodraphical statistics method,analyzed the situation of land use.Then on this basis,distinguished the tpye of humanity factor which affect on LUCC,researched the relationship between humanity factor and LUCC by the means of the spatial analysis function of GIS and SPSS.The following conclusions are obtained.(1) For study area,in space aspect,forest is the main land use type,cultivated land is mainly distibuted in the flat area.The area of unused land、cultivated land、grass land and water are decreased. The area of forest and constuction land are increased.In dynamic degree, the avtive type are cultivated land 、 constuction land and unused land, grass land is the slowest,forest and water is different.In the aspect of space,the shape of the change regional is mainly strips and broken patches,which are located in Han Zhong、An Kang and ShangLuo between the degree with 0°-20° and the little changes is above 30°.(2) Results Quantitative analysis showed that population density、AGDP、grain total outout、total power of agricultural machinery、perurban resident incomes and male to female ratio are six key humanity factors which impose impact on land use changes in Qinling. By mult-variable lineaar return analysis,it shows that LUCC in QinLing is influenced by the population size、living standards、production requirements、agrotechnicallevel 、conservation policy.(3) Results Spatialization analysis showed that the spatial correlation between the typical human factors index and LUCC in Qinling is related to the slope. The intensity of spatial correlation between the two decreases with the increase of slope.The population density and LUCC spatial relevance is more prominent in the slope for 0 °- 10° and the mainly affect land use type is construction land and unutilized land;Between the slope of 10°- 20°, spatial correlation between grain yield and LUCC showed significantly more prominent and the mainly affect land use type is cultivated land.
