Analysis Of Ecological System Service Value Assessment And Landscape Pattern In Kuangyan Cixi

According to the aviation image in2009as the information source， the application ofremote sensing (RS)， geographic information system (GIS)， through the use of ENVI4.3andArcGIS9.3and other related software， making type vector landscape Kuang Yan Town Cixi Cityland use， land form， landscape patch from the towns urban land use landscape patch scale，urban landscape spatial structure， urban land use spatial relations and other aspects of thecharacteristics of Cixi Kuangyan town spatial pattern analysis. By the help of statistical method，it also studied the spatial autocorrelation and spatial interpolation of their ecosystem servicefunction value intensity and constructed the grid network of ecosystem service function value ofthe district on a small scale with high precision. The results showed that the total of ecosystemservice function value in Kuangyan town in2009was2091.896million RMB and the intensity ofits spatial distribution revealed obvious spatial autocorrelation as a whole. However，it would begradually decreased with the increase of spatial distance. Through Kriging interpolation method，its local spatial autocorrelation showed two "high-high" aggregations and one "low-low"aggregations obviously， i.e. central diffuseness form along with principal axis from "high-high"aggregations in the northwest to "low-low" aggregations in the Southeast in the regional town. Bythe quantitative research of regional ecosystem service function value， it could reveal thedependence and heterogeneity on the scale of regional town space and reflect the characteristicsand law of spatial distribution of ecosystem service function value intuitively.
