| As one of the most essential production factors of industrial development,land is regarded as an inevitable space and place for industrial development.It plays important roles as the carrier and the holding power in the development of industry.Under the circumstances of reform and opening up to the outside world,along with the rapid growth of social economy in the 21st century,the issue of how to utilize land resource effectively has aroused extensive concern of scholars in the academic field and pioneers in the society.Land use problems affect economic development,ecological environment as well as the harmony and stability of the society.Under the premise of constantly adjustment caused by the result of social economic development pushing forward the industrial structure,it is necessary to propose a new request on the structure of land use,which will further influence the demand of land,the scale and the spatial distribution of various land resource in urban areas.Therefore,the relationship between the land use structure and industrial structure can be conceived as a unity of interaction.Several issues on how to coordinate the relationship between the change of industrial structure and the adjustment of land use structure,how to solve the contradiction between the economic development and the shortage of land resource,and how to realize"double optimization"of land utilization and industrial structure,have becoming a major concern among the society.It is of great practical significance to the healthy development of the economic society.Under the guidance of the theories in industrial economics,geography,land science,sociology,etc,the thesis also take the evolutionary review and the developing trend of current national and regional industrial structure in to consideration,as well as the structure of land resource utilization.It makes use of research ideas and techniques which have been used in the field of systematics,statistics,metrology,and other disciplines.The organization of the thesis is built by following the research framework of"basic theories--sample region empirical--countermeasures”.Firstly,the thesis systematically summarizes and analyzes the domestic and international research achievements and future trend on the topic of land use structure and industrial structure as well as their relationship,hoping to make a breakthrough and create a possible innovation;secondly,the thesis respectively analyzes the current situation of land use structure and industrial structure in both the urban areas and the street towns of Longchang,and studies the feature related to the landscape of land utilization,including the important index of PD?patch density?,LPI?largest patch index?,LSI?landscape shape index?,CONTAG?contagion?,COHESION,SPLIT?splitting index?,SHDI?Shannon's diversity index?,SHEI,and AI;Thirdly,construct the regression model of variable coefficient,and measure the influence of the industrial structure on land use structure from the urban areas to the 19 towns in order to reveal the nature and size of the influence;what's more,this thesis in tends to figure out the key factors of the driving force behind the change of land use cover and analyze some outstanding problems existing in the development of industrial structure and land use structure in Longchang,as well as propose some countermeasures.The conclusion of the thesis includes:?1?With the aid of remote sensing method,we can obtain remote sensing image data of Longchang of in the year of 2000,2005,2000 and 2015.Processing the four images and then evaluating the precision of them,we can respectively get the result of Kappa index.They are 0.813,0.821,0.831,and 0.821.This shows that the precision of remote sensing interpretation is higher than 80%,in other words,it successfully meets the needs of study.?2?The thesis also conlcudes the changes of land use structure in Longchang In the perspective of land use structure of the whole city in Longchang,the scale of different land use types presents the following structure:arable land>woodland>land used for construction>water area>grassland>unused land,which accounts for 66.91%,13.79%,13.76%,13.79%,10.75%and 3.70%of the total proportion of land use respectively.The evolution characteristics of the landscape index relating to the other 9types of land use,including the patch density,largest patch area,landscape shape index.etc,show a continuous increasing trend on the degree of land use and the development of land.On one hand,the continuous increasing trend of the overall change rate,in terms of the six major types of land use structure of the whole city,indicates that the scale of the total land use increases greatly and deeply at different periods of time.On the other hand,the increasing trend of the overall equilibrium degree relating to the six types of land use indicates that the gap between the various types of land use is narrowing year by year.?3?Changes of regional land use structure is also concerned in this thesis.From the view of 19 towns'land use structure,we can classify land use of Longchang into three types,that is,land mainly used for construction,land mainly used for forest and water area.In detail,land used for construction can mainly be found in Guhu,Jin'e and Shanchuan;land used for forest is mainly in Shi Yanqiao,Jieshi and Shengdeng;water area were is mainly in Guhu Street.From the view of the changing scale of different types of land use,we can classify the land use of Longchang into the increasing type and the decreasing type of land used for construction.In detail,land used for construction increased in 13 towns including Guhu,Jin'e,and Shanchuan;it,however,decreased in 6 towns including Xiangshi,Shuangfeng,and Yingxiang.If we classify land use into the increasing type and the decreasing type of arable land,we will find that arable land increased in 9 towns,including Longshi,Yingxiang and Jieshi,while it decreased in 10 towns,including Guhu,Jin'e and Shanchuan.If we classify land use into the increasing type and the decreasing type of woodland,we will find that woodland increased in 8 towns,including Guhu,Xiangshi and Huangjia,but it decreased in 11 towns such as Jin'e,Shanchuan and Shengdeng.Moreover,if we classify land use into the increasing type and decreasing type of grassland,we will notice that grassland increased in all the 18 towns except Shi Yanqiao.Lastly,unused land decreased in 3 towns such as Jin'e,Shanchuan and Yunding,while other towns remained steady.?4?The thesis concludes the changes of industrial structure in Longchang According to the total output value of the city's three major industries,primary industry increased by 2291.04 million yuan,with a decline of 13.17 percentage points;secondary industry increased by 2291.04 million yuan,with an increase of 26.72 percentage points;tertiary industry increased by 4718.71 million yuan,accounting for a decline of 13.55percentage points.Generally speaking,the changing rate of the city's industrial structure appears to be a tendency of declining after promoting,which suggests that the change of industrial structure had constantly intensified from 2005 to 2010 but the change had constantly weakened from 2010 to 2015.The continuous decreasing tendency of the overall change rate relating to the city's industrial structure shows that the gap of the output value between different industry is widening year by year.?5?The thesis draws a conclusion on the changes of regional industrial structure.Viewing from 19 towns'industrial structure,the output value of the three major industrial had changed from"3-2-1"to"2-3-1",and all of them had experienced different growth rates.The primary industry in Guihuajing town increased by a largest margin,by 10660.80 million yuan.The growth of the secondary industry in Lishi town was the largest,with a rise of 53486.87 million yuan.The growth of the tertiary industry in the Jin'e Street was the largest,with an increase of 323521.33 million yuan.?6?The change of land use is closely allied to the change of industrial structure in Longchang city.In the terms of the relationship between industrial structure on and land use structure,industrial structure has a positive influence on land use structure.C-value at three different periods of time was respectively 1.5216,3.6035 and 0.1837,which indicates that the effectiveness had experienced a process from rise to decline.;Nevertheless,the influence of 19 towns'industrial structure on land use structure was positive.In detail,the industrial structure of Guhu Street and Jin'e Street had the most significant influence on land use structure.The influence intensity of the two was 2.07and 2.69,while the influence intensity of the other towns was relatively smaller.Through careful analysis,the wholesale&retail and construction were the main driving factors behind the changes of land use structure in Longchang,and their impacts on the change of land area were relatively higher.In current situation,there still exists a lot of difficulties and problems remained to be solved in the harmonious development of industrial structure and land use structure,such as a rapid decline in cultivated land,a sharply growth in construction landt,and a mismatch of land use and industrial space.,In order to solve these problems,we need to take actions in the following ways.First of all,we should protect arable land as much as possible.Secondly,we need to use land resource for construction more effectively.Last but not the least,we should improve the spatial distribution between industry and land use.?7?In the view of the driving factors behind land use structure,the wholesale&retail and construction business are the driving force behind the change of land use structure in Longchang.In terms of driving factors behind the view index of land utilization,construction has a great impact on the patch density,while forestry has the smallest impact on it.Agriculture has the strongest impact on land utilization view shape factor,while storage and post service has the smallest.In terms of Shannon's diversity index?SHDI?,agriculture has the strongest impact,while industry has the smallest. |
