Research On The Improvement Of Comprehensive Land Carrying Capacity In Xining City

Land carries a set of activities,contain material resources and economic advancement,which are needed by the production and life of human society.and also has important ecological functions.Its indispensability and limited supply make it a significant position in many resources.As China’s economy succession to exploitation fast with high superiority,the Urbanism process is constantly accelerated With the successive expand of industrialization,the regional population is increasing,It causes the persistent decline of foster land area and the decline of ecological conditions quality.Already be a rigid control of China’s development its suffice the demand of the current from hazard the capacity of approaching descent to satisfy their possess demand.The goal is to mitigate the phenomenon that land resources are not enough to meet the needs of the population.we need to optimize the land spatial layout based on the research on synthetical bearing capacity of earth,so as to furnish buttress for regional buttress growth.(1)By interpreting the distant RS of Xining City,integrate with the landgrave use database of Xining City in 2015,2010 and 2018,analysis of the text the actuality of earthuse and changes in the amount and speed of earthuse take in Xining town,and finding out the existing characteristics and transform for land take advantage of in Xining town.Existing problems;(2)Starting from the three functions of land ecology,life and production integrate with the practical circumstance of Xining City,construct a land-use assessment model based on the Bearing ability of the territory in Xining City,integrate with the practical condition,construct a bearing ability of the land appraisal index method in Xining City.determine the contribution degree of the index by using the entropy the overall carrying capacity in Xining city from 2005 to2018 by using the grey target model.(3)Through grey relational analysis10 highly interrelate synthesis appraisal method index of territory bearing capacity in Xining City are selected.GM(1,n)model is used to simulate the prediction value of land comprehensive carrying capacity from 2005 to 2018,and the imitate results are relatively with GM(1,1).The model with better imitate effect is selected to predict the land comprehensive carrying capacity of Xining from 2019 to 2024.Research shows:(1)From 2005 to 2010.The extent of land utilization variation is relatively drastic,and the extent of land utilization variation is relatively large,with an annual alter ratio of 7.52%.From 2010 to 2018,the extent of land utilization alter was opposite change range is small compared with the previous cycle Throughout the research cycle,construction land has shown an upward trend,this is correlative to the community and economic advance and the dilation of the scope of the city,while the farmland in Xining City has reveal a decline current.resulting in a decrease in total arable land.Cereal yield has rejected in nearest years.(2)From 2005 to 2018,the ecological bearing capacity of the territory in Xining growth to 0.5385 to 0.8262,and the carrying level alter from low extent to higher extent;the manufacture bearing force increased greatly,from inferior standard to above standard,and the score of carrying capacity increased from 0.6311 to 0.8451,or33.90%;the evaluation value of life carrying capacity increased from 0.5642 to0.4929,or 62.5%.In the past 14 years,the relationship among the three subsystems has changed frome cological living capacity manufacture bearing potential to ecological bearing potential manufacture bearing potential activity bearing potential.Three element affect the land bearing potential of territory synthesis bearing potential subsystems of land ecology,production and living,which increases from0.5843 to 0.8183,and the carrying capacity level changes from lower level to higher level.(3)Through the grey correlation analysis of land synthetic bearing capacity Xining City,it is concluded greening ratio,living area,each capita dwell Road township,per capita housing area,and food cost a linchpin part in the evolution of territory synthetic bearing capacity in Xining city.etc Taking these 10 indexes into GM(1,n)pattern,the equation compare deviation of prognostication is 1.09,which is better than 1.27% of grizzle GM(1,1),The model predicts the land synthetic bearing capacity of Xining city from 2019 to 2024,and concludes that the comprehensive carrying capacity of Xining City in the next six years is on the rise,and the maximum value of land comprehensive carrying capacity in 2024 is 0.9413 relative to that in2004.(4)According to the study consequenc,this study release onward suggestions to boost the entire carrying land capacity of Xining from four side: strict cultivated land protection system to Strong production growth territory bearing capacity;reinforce infrastructure explanation,ibooste the bearing capacity of the territory of the living;protect the ecological surroundings to boost the territory ecological bearing capacity;balance the population distribution and establish the awareness of sustainable development.
