Based On The Crop Planting Ecological Footprint's Sustainable Development Study Of Jiangsu Province

With the spread of the industrial development in the world,the economic developed quickly today.But economic highly developed destroied the environment at the same time,like the water loss?soil erosion?ecological diversity?land degradation and so on which have been increasingly serious ecological environment problems.As the ecological environment problem is widespread,which has seriously hindered the progress of human society.It is why the concept of sustainable development put forward in such a environment.With the deepening of the international research on sustainable development,the sustainable development of all kinds of index system has been put forward as well,in the indicators,the ecological footprint method is getting more and more scholars at home or abroad the recognition and praised highly.The ecological footprint model can define the sustainable development of the research object state clearly,and compares the calculation results at the same time,has the characteristics of strong interoperability and portability.In the economic and social development,agriculture has been at a important position of the fundamental,and for the whole agriculture,farming is the important constituent,therefore research on the sustainable development of the planting industry will be a sustainable agriculture,and a solid foundation for the sustainable development of the whole society.Jiangsu is not only our country's economic strong province,it is China's top agricultural big province at the same time,and the contradiction between the ecological environment has become increasingly prominent.According to the?China report 2015-ecological carrying capacity,ecological footprint city and development?,Jiangsu is a bigger province of ecological footprint and is the ranking one of the provinces in the first three.Due to the Jiangsu province's farming and crop production in the country is larger,the study of sustainable development of the planting industry in the province to the Yangtze river delta and even the whole country has very important significance.This paper compare to the current popular method to improve and perfect the ecological footprint,ecological footprint from crop production and crop planting industry in Jiangsu province in the view of consumption of ecological footprint to the research and evaluation on sustainable development.This article will be fine to crop production in jiangsu province ecological footprint account class divided,determine suitable for the study of related parameters in the ecological footprint model.Characteristics of crop production were analyzed,and the analysis of Jiangsu province from 2005 to 2014,between different cities and different types of land productivity in the region,the difference between the annual as well.Production for crop production and crop ecological footprint consumption footprint for empirical research,research and crop production around the city of jiangsu province in 2005 to 2014 and crop ecological footprint consumption production footprint of spatio-temporal difference;And on crop production(consumption)empirical research ecological carrying capacity,the main research and crop production around the city of jiangsu province in 2005 to 2014(consumption)spatio-temporal difference of ecological carrying capacity,and ecological footprint for crop production and crop ecological footprint consumption balance analysis.The use of crop production and crop ecological footprint consumption two concepts of ecological footprint,full of crop production and consumption activities on the ecological system of jiangsu province population were analyzed,and the impact of and crop production and crop ecological footprint of jiangsu province consumer to compare the ecological footprint analysis,so as to more clearly understand crop production and crop products in jiangsu province consumer activity influence on ecological environment and function.Finally from jiangsu province crop planting production sustainable index,consumer pressure index of crop planting industry in jiangsu province comprehensive research on the sustainable development of ecological and economic analysis.We can have conclusions are as follows:(1)Between crop production around the city in 2014,jiangsu province,there are big differences in ecological footprint of the 13 cities in the whole province,yancheng crop production of ecological footprint is the largest,wuxi minimum,including crop production of high regional ecological footprint,is in jiangsu province of the main crop production,crop yields more each year.Between crop production around the city in 2014,jiangsu province ecological carrying capacity difference is obvious,the distribution of crop production in northern areas of the ecological carrying capacity is generally more than middle and southern areas,the total crop production of yancheng ecological carrying capacity,the biggest crop production of wuxi minimum area ecological carrying capacity of water and soil resources endowment,arable land and fresh water source sites of production factor is the two main factors that affect crop production of ecological carrying capacity,between various cities in jiangsu province,jiangsu,middle and north jiangsu three area of arable land and the uneven distribution of water resources has obvious characteristics of cultivated land resources and water resources,subei occupies obvious advantage in total.(2)Crop production in jiangsu province from 2005 to 2014 the overall ecological footprint is a volatile downward trend,amplitude of overall haven't changed much.Nearly ten years crop production in jiangsu province ecological carrying capacity is also on the rise,at the same time in the crop production in jiangsu province has been stable during the period of present ecological surplus,on the whole,a trend of fluctuations rise.The developing mode of crop production in jiangsu province at present is in a state of relative sustainable development,the present situation of the ecological environment is relatively safe,a region of the ecological capacity of basic can maintain the ecological balance of crop production,basically realize the sustainable development of the crop production.(3)Crop consumption between 13 cities in jiangsu province in 2014,the ecological footprint of difference is bigger,including nanjing,xuzhou,suzhou plant ecological footprint consumption is bigger,in the position of the top three,in the province crop consumption ecological footprint of the highest in nanjing,the smallest is in zhenjiang,jiangsu area of crops to consumer surplus value smaller relative middle and northern jiangsu area.(4)Crop consumption ecological footprint of jiangsu province in 2005-2014 a falling volatility trend on the whole,consistent with the above production change trend of the ecological footprint,nearly 10 years,jiangsu province crop consumption are smaller than the local ecological carrying capacity,ecological footprint shows its own natural capital of jiangsu province to some extent,can according to the set of local resident population of consumer demand.(5)Crop production in jiangsu province in 2005-2014 index of ecological sustainable development between the change in the range of 0.5 to 0.75,according to the use of the resources in the crop production in general is in a state of a weak sustainable,rise by a fluctuation trend of development.Spatial distribution,2014 crop production around the city of jiangsu province in the utilization of resources are in a weak sustainable state.Can be found through observation,sustainable crop production in the areas of southern degree is generally lower than middle and northern regions,one of the highest ecological sustainable crop production index is suzhou,nanjing are the lowest.
