Research On Sustainable Development Of Panzhihua Based On Ecological Footprint Method

The resource-based cities which are b ased on the exploitation and processing of natural resources are facing transf ormation.The sustainable developm ent of resource-based cities is the premise and foundation of the transf ormation and development.Ecological footprint is an im portant indicator to m easure the degree of regional sustainable developm ent.In this paper,the ecological footprint m ethod and sustainable development evaluation index are used to evaluate the sustainable development of Panzhihua in recent 15 y ears(2000~2014),a typical resource-based city,and discussing the relationship betw een per capita ecolo gical footprint and economic development,The results show that:(1)In the past 15 years(2000~2014),th e per capita ecological footprint of Panzhihua increased from 5.493hm2/per in 2000 to 13.633hm2/per in 2014,an increase of 148%.Among them,the per capita ecological footprint of fossil energy land accounts for a lar ge proportion,which is the m ain reason for the rapid growth of per capita ecological footprint.In the past 15 years,th e per capita ecological carrying capacity of the city has increased slightly(from 0.822hm2/per to 1.387hm2/per).Among them,the per capita ecological carrying capacity of forest land was the largest(63.01%),the per capita ecological carrying capacity of water area was the fastest.In th e past 15 years,the city has b een in a state of ecological deficit,and there is a trend of further expansion.Ecological deficit(surplus)of all kinds of productive land area,in addition to woodland and ecological conditions in the waters after 2007 was surplus construction,but the arable land,grassland and fossil energy land showed an ecological deficit.(2)The evaluation of sustainable development based on ecological footprint method.The Results show:Over the past 15 ye ars,ecological footprint per ten thousand(yuan)GDP decreased year by year(from 4.941hm2/ ten thousand(yuan)to 1.752hm2/ ten thousand(yuan)),a decrease of 65%.It shows that the uti lization rate of resources is increasing year by year at the same tim e of economic growth.The city’ s ecological pressure index decreased year by year(down from 1.628 t o 0.965).According to the classification criteria of ecological pressure index,the ecological press ure is changed from unsafe to unsafe.The sustainable de velopment of the city has been im proved slightly,and the ecological footprint diversity index has fluctuated between 0.423~0.817 in the past 15 years,the change trend is stable,which indicates that the com position of the ecological footprint tends to be r easonable.Eco economic system developm ent capacity index slightly growth tre nd(from 4.334 to 5.780).It shows that the development ability of the city in the past 15 years has been continuously improved,and its future regional sustainable development ability is we ak.With the further growth of the ecological deficit,the consumption of resources to pr omote the development of the city is not conducive to regional sustainability.(3)Since the founding of Panzhihua city,the course of econom ic development mainly includes four aspects:The initial stage of the industry(1965~1977),the stage of industrialization(1978~1985),the stage of i ndustrial diversification(1985~2000)and the stage of econom ic transformation(from 2000 to now).On this basis,the paper analyzes the relationship between per capita ecological foot print and econom ic development index of Panzhihua during the period of econom ic transition in 2000~2014.The results show that the ecological footprint per capita and per capita GDP,the proportion of the second industry,urbanization rate,disposable incom e of urban residents,rural residents incom e,total re tail sales of social consum er goods and investment in fixed assets accoun ted for positive related to the proportio n of GDP,and the proportion of the prim ary industry and the proportion of the third industry is different from the corresponding.This has a great relationship with the current situation of Panzhihua’s industrial developm ent and the change of people’ s consumption structure.From the side reflects the main reasons for the changes of ecological footprint per capita in Panzhihua city is industrial development caused by resources especially the energy resources consumed and people’s consumption structure change caused by the per capita ecological footprint structure of the biological productive land type change.(4)Comprehensive analysis of the status of sustainable developm ent in Panzhihua and the relationship between econom ic development and the process of econom ic development,the main problems of sustainable development in Panzhihua include:High consumption of resources,especially the high dependence on fossil ener gy resources;The land resource structure is unr easonable,the ecological carrying capacity is narrow;Industry relies heavily on heavy industry,the use of resources is relatively simple.The following m easures should be taken:To strengthen the depth of the development of m ineral resources,im prove the utiliza tion efficiency of resources;Comprehensive utilization of ag riculture,climate,biological and other resources;To control population growth and promote conservation and diversification of consumption patterns;Accelerate the transf ormation of social econo my,optimize the industrial structure;Returning farmland to forest and grassland,strengthen ecological environment construction.
