Land Bearing Capacity In Guanzhong Area

In recent years,along with the deepening of the western development and the speeding up of urbanization,shaanxi province human resources and land resources demand continues to increase,the Guanzhong region,led by Xi 'an,as a key area in the west development as well as the starting point of "One Belt And One Road",to develop more quickly.Rapid development in the increasingly prominent contradiction between human and land,arable land decrease,environment pollution problems such as rising,land bearing capacity condition becomes serious,as soon as possible to find clear bearing short board and to solve,is the best choice to maintain the sustainable development of land.On the basis of previous research on land carrying capacity,using the method of suitable construction land resources evaluation index and Ecological Footprint Theory,respectively to study the bearing capacity of useable construction land and the bearing capacity of cultivated land and combine the results,to analyzes and summarizes the Guanzhong regional land comprehensive carrying capacity and sustainable development ability.Finally,some suggestions are put forward to solve the problems of land carrying capacity in Guanzhong area.The main results of the article are as follows:1?In addition to the middle districts of Xi'an City outside,the bearing capacity of useable construction land in Guanzhong area is in good condition.In terms of capacity distribution,the north is better than the south;and in terms of carrying capacity,more than 60% of the counties in the region are in the surplus region,and more than 20% of the counties are in the rich zone2?the Guanzhong area of cultivated land bearing capacity study results show that the central of Guanzhong area,that is the most counties of Xi'an city and Tongchuan new district,the occurrence of cultivated land are overload or overload.Some counties in the vicinity of Xianyang is also in a critical state of equilibrium.Most of the remaining counties are in a state of surplus or wealth.In general,the northern region is superior to the South.3?Based on the comprehensive analysis of the carrying capacity of available construction land and the carrying capacity of cultivated land in Guanzhong area,the comprehensive carrying capacity of the land shows that most of the districts and counties in the middle of Guanzhong area and the Taibai County of Baoji city are in the state of limit of carrying capacity,and the other counties are in good condition.Central part of Xianyang,as well as Tongchuan,Baoji,and the central of Weinan are in the state of load balance.Most of the counties in the eastern,western and southern parts of Guanzhong area are in the state of carrying surplus,and in the north of Guanzhong area show bearing rich state.According to the above results,the overall capacity of Guanzhong area are in good condition,but in the middle of Guanzhong,such as Xi'an and parts of Xianyang,due to a variety of factors of population,location and area,carrying a poor state,need to be taken seriously.
