| Urbanization process had directly affected the change of landscape pattern of land use in the area,which has a significant influence to the urban environment.Chenghua District is one of the main districts of Chengdu.Along with the rapid urbanization of chengdu,established in the area is growing,the population and economy is increasing over the past 15 years.Dramatic changes have taken place in the landscape pattern of land use,which caused huge impact on the urban ecological environment.In recent years,the change of landscape pattern of land use in the process of urban development has become one of focus in the study,a lot of work on land use is carried out both at home and abroad,but little was researchedin land use change ofchenghua district of chengdu.Therefore,this article was based on the data of 2000,2010 TM remote sensing images and 2014 Google's satellite images of chengdu and related social economic data,using GIS and RS technology and the principle and method of landscape ecology,landscape change and driving forces of land use of a greater analysis,reveal 15 years into greater China in the process of urbanization and land use change rule and trend of the landscape pattern,and put forward some Suggestions on landscape pattern optimization.Thesis mainly is divided into six chapters.Chapter One:Introduction.An overview of the concepts and research status of land use and landscape pattern to clarify the basic idea of the study,specific research methods and techniques used in the study course,the process described in detail in this paper data sources and remote sensing data,and to evaluated the data processing accuracy.The second chapter:study area.Introduce the Chengdu Chenghua administrative division,natural profile,socio-economic profiles and tourism resources.The three Chapter:Chenghua landscape Dynamic Analysis.Remote sensing interpretation data,statistics Chenghua in 2000,2010 and 2014 the area of land use type situation six categories analyzed changes in the past 15 years of land use structure change Chenghua overall situation and various land area of computing regional land use transfer matrix change.Chenghua past 15 years overall land use are:2000 to 2010the greatest change of cultivated land decreased from 31.74 km~2 to 7.27km~2,a 77.1%decrease.After the city from 2000 to 2010 after the rapid development process,during2010 to 2014,increased from 64.42 km~2 impervious surface to 67.95 km~2,an increase of 5.5%;green increased 0.87 km~2,arable land decreased 0.9 km~2,land the use of small changes.The fourth chapter:analyzes of land use landscape pattern.Economic development and regional dynamic changes of landscape pattern are inseparable,Chengdu Chenghua rapid economic development in recent years,expanding the regional construction area,huge landscape pattern change,through an analysis of Chenghua pattern,we can better understand urban land use basic rules and trends evolve,to promote sustainable land resources in the study area and the proposed use of the coordinated development of urban ecological environmental protection as well as theoretical reference value.Analysis of changes in Chapter fifth of factors influence land use and optimization recommendations.Land use change is largely due to human demand for land caused,therefore,this article will focus on urbanization,population,economic and policy factors to analyze its impact on the land change.The sixth chapter:Conclusion.In this paper,Chengdu Chenghua 2000,2010,2014 remote sensing images,combined with the relevant data,the use of GIS,RS,FRAGSTATS landscape pattern analysis software Chenghua fifteen years,changes in land use and landscape pattern analysis research,come with urbanization and changes in land use and landscape pattern Chenghua fifteen years great changes. |
