Landscape Pattern And Spatial Autocorrelation Analysis Of The Land Use

Fosusing on the social property,Land utilization refers to the using condition of the soil.That is to say,people engage on long-term or cyclic management and governance reform activities against land according to the natural characteristic of the land by the means of economic and social purpose.In other words,land utilization is the process of coverting natural ecological system into artificial ecosystem and another process where nature,econoy,society and other factors all toghether doing it.The ways of social productivity which is utilizated by being with using mode and situation play crucial parts of it,including popuse and intention of human land utilization.Zhongjiang county,deyang city is typical region in Hilly Area of Central Sichuan Basin,reseaching about it is relative to many aspects such as agriculture,soil,climate,plant covering and ecological circumstances.In order to aquire more knowledge on regional land utilization pattern and its change law and provide certain theoretical scientific evidence about local sustainable land resources utilization,the author takes measures like RS,GIS,landscape pattern analysis,spatial statistics and other ways to make a survey on landscap quatiative and dynamic studying.In the meantime,based on landscape pattern,it is available to obseve the land changing condition from one type to another from degree of fragmentation and diversity of landscape pattern,and this important reference is conducive to making policy on local sustainable development strategy,land utilization planning,land management policy and other factors that are correspondent to epidemic situation.The main conclusions are following below:1.As a result of the high degree of landscap patter fragmentation in zhong jiang county,the shape of plaque is complex and various.Though the aggregation level is in a intermediate conditions,the physical connections are in a high level.The different kinds of plaques is blow the average agglomeration standard,but eveness of area distribution in various kinds plaque is up the average level.In the last ten years which ranged from 2004 to 2014,the shapes have become more and more complex,the aggregation degree of both plaques has been in a lower tendency,and the physical connections have been in a higher level,the eveness of area distribution in different plaques has been increase a little,that is to say,the acreage in different plaques is somehow identical to each other.The main reason leading to more landscape fragmentation in researching area is the more amount in plaques.2.On the basis of fragmentation degree of landscape utilizatio pattern in zhongjiang county from 2004 to 2014,the whole of spatial distribution had been in a negertive correlation.and it had reached to significant level by using confidence test.but it presented a little high level of aggregation tendency and increased the possiblity of randomness.However,the diversity spatial distribution in zhongjiang couty landscape pattern had been in a completely negetive correlation partly from 2004 to 2014,but the randomness that happened this case was not absolutely dominent with confidence test.Though landscape pattern diversity had been in a dispersive tendency with the time approching,generally speaking,changes were not remarkable.3.Based on the aggregation result of local autocorrelation and significance test in landscape utilization pattern,the aggregation in local spatial distribution presented high-low aggregation outliers or low-high aggregation outliers including H-H high value accumulation area,L-H low and high abnomal gathering area and unremarkable area.But each on of the significant area had been in a little increased or decreased tendency in the last few years.Acoording to the diversity result of local autocorrelation and significance test in landscape utilization pattern.the landscape pattern diversity in lacal spatial distribution represented H-H gathering value in 2004,the landscape pattern diversity represented H-L abnomal gathering value or L-H abnomal accumulation value in 2014.And main areas included H-H high value accumulation area,L-H low and high abnomal gathering area,H-L high snd low abnomal gathering area and unremarkable area.The H-H high value area had changed a lot,but others had changed a llitle.The main factors affecting land utilization pattern included three aspects:humanity factor,economic factor and policy factor.
