Study On Ecological Carrying Capacity Of Fuyang City Land Based On Ecological Footprint

Fuyang city is an important energy reserve base in China and also supplies part of China’s grain production.From this level,the bearing capacity of Fuyang city’s land directly determines the basic situation of Fuyang city’s supply of resources to China.It has a significant impact on the surrounding ecological regional economy,China’s energy reserves and food security.For developing regionaleconomy policy in recent years,Fuyang city nearby resources by excessivemining,while the local economic development,urban expansion speed is also very obvious,but obvious ecological behavior destruction,land resources under the threat of the larger environment,especially the relationship between Fuyang cityresources supply and demand imbalance increasingly obvious.Based on the current situation of land resources in Fuyang city,it is urgent to conductan in-depth study on the ecological carrying capacity of land in the whole city and eachadministrative region,and put forward some valuable Suggestions.This paper selected five ecological footprint and ecological carrying capacity,according to the different parts of the grain production,productive land area estimates the Fuyang city in 2014-2018 land ecological carrying capacity,land ecological carrying capacity of Fuyang city and the surrounding area was calculated,it is concluded that the important factors influencing the Fuyang city land ecological carrying capacity,to study specific conclusions are as follows:(1)From 2014 to 2018,the total ecological footprint of Fuyang city increased from 0.6227 hm~2to 0.6674 hm~2,showing an overall upward trend,but with a small range of change,indicating stable production and less damage to the ecological environment in recent years.(2)From 2014 to 2018,the ecological carrying capacity of Fuyang city’s land increased from 0.322676 hm~2to 0.393862 hm~2,showing an overall rising trend,indicating that the ecological condition of Fuyang city’s land is in a state of gradual improvement despite of ecological pressure.(3)Compared with the ecological footprint from 2014 to 2018,the ecological carrying capacity of land in Fuyang city has always been low,and the ecological deficit has always been in a state,which reflects that Fuyang city still faces a severe ecological situation.(4)Each index of Fuyang city shows that the active land consumed too quickly,which is far greater than the original carrying capacity of land ecology,resulting in the overwhelming majority of land is overdrawn.Especially in the aspect of ecological deficit,ecological pressure and level are in an unstable state,and the coordination index between ecological pressure index and land carrying capacity is very uncertain.On the whole,the resource pressure and bearing capacity of Fuyang city are unbalanced,that is,the bearing capacity is less than the bearing capacity.(5)In recent years,has been a steady rise in Fuyang city land bearing pressure is situational,Fuyang city land ecological pressure increasing,land for construction is too,ecological land within the urban declining,forced to land for construction area more and more,the imbalances in terms of land bearing capacity of the region coordination coefficient decreased significantly.In the article seems to have the following several main reasons,first of all,with the scale expanding of urbanization,the urban area of ecological land is losing their proper role,along with the increase in the productive land,the land bearing pressure also increases,secondly,mounds of grain production ability made its supply position,but it is also the strong supply capacity,the city’s land bearing pressure.
