Analysis Of Landscape Pattern Of Tideland Reclamation Area Based On Remote Sensing Data

Abstract:the reclamation area of Coastal landscape of Cixi,Jiangsu Haimen and Lian yun gangwere studied.Based on three TM images data of Cixi in the2000,2006and2013, landscape dynamicchange process of the reclamation of Cixi during the past13years were analyzed quantitativelyusing of landscape indices model, RS and GIS technology. The results showed that:①there aresignificant differences in series time variation of landscape reclamation region of Cixi;②The areaof landscape reclamation region tended to increase during the past13years, the most obviouschanges of which were aquaculture pond landscape;③The area between the inner landscapedynamically transformed into each other frequently, evidently showing mutual transformation ofbuilding, water, Woodland, architecture and aquacultural ponds;④landscape shape became morecomplex during the past13years: landscape diversity index increased while The evenness indexand dominance index decreased;The degree of landscape fragmentation aggravated and the overalllandscape heterogeneity increased.Based on1989,1989and2014years three TM images data of Haimen with the support oflandscape indices model, landscape dynamic change process of the reclamation of Haimen duringthe past30years were analyzed quantitatively.A period of rapid development happened in the landuse of all kinds of landscape pattern of Haimen,reclamation area happened to be obviousspatial-temporal change; landscape architecture were increasing,agricultural forest, grassland areaof landscape types were decreasing while water landscape changed slightly, the landscapearchitecture to grow faster than the decreasing speed of agricultural land;25years landscapefragmentation degree increased.Combined with Haimei documents,it can come to a tentativeconclusion, Haimen city landscape economic development at the same time,the ecologicalenvironment landscape Haimen needs to be further improved,increasing the protection of theecological environment and management.Based on1987,2000,2014remote sensing image,Take the reclamation area LianyungangCity for an example,using Erdas8.7,Arcgis9and Fragstats3.3software platform to interpret,analysis landscape ecology quantitatively.discusses the features, and landscape pattern change inthe study area land in recent27years,results showedthat: in the reclamation process,city landcontinued to increase,mainly realized through the occupation of agricultural land.In all types ofland use were listed first in the reduction of agricultural land area,area reduction range was the largest,the construction land is the main flow. Can probably derived from now,from20years to astable period after reclamation of coastal areas, agricultural land,forest land area will continue todecrease,the water and the construction land will increase year by year.Population growth,expansion of the city,the progress of science and technology were the main driving factor of Lianyun gang reclamation of the landscape pattern change,by this research it can be a preliminaryconclusion:the future city construction must take measures to protect the vulnerable arealandscape,such as farmland,woodland,water etc.
