Coastiline And Area Of Evolution And Genetic Analysis To Use The RS Images The Bi Jia Mountain

In the paper,using the remote sensing and geographic information system technology.Based on the Landsat.GF-2 video and 2015 fieldwork measured the measured data,Through extraction and analysis of five remote sensing image processing and the coastline information for the Bi Jia mountain Further according to the analysis of the specific cause of these changes.The main work and achievements are as follows:Using the correlation of the geographic information system for 2015 coastlines of the remote sensing image information extraction,and measured 2015 using traditional methods,Using supervised classification to verify the precision and accuracy of measured data and remote sensing image data.Through to the coastline and area of calculation and statistics,the results show that in the 31 years,Bi Jia mountain island coastline length showed a trend of decline,the coastline to reduce total of 269 m,area of 13426 m,regardless of the coastline or area of the impressive speed reduction.Adoption Through detailed contrastive analysis of every two issue of remote sensing image is:from 1990 to 2000 and from 2000 to 2010,the two periods,the coastline and area of the big changes in the degree,the coastline 132 m and 89 m respectively,Area of 6904 m2 and 4163 m2 respectively through calculation,the coastline in the two periods respectively accounts for 1/2 and 1/3 of the whole area of 3/5 of the overall change and a third.If the Bi Jia mountain subdivided into things on both sides to study,but also to the west and the east coast to reduce the extent of the total respectively by 4/5 and 1/5.Based on the study of the five phase of the remote sensing image,and combining with related data conclusion from 1990 to 2000 year in this period of time,the establishment of Jin Zhou port.From 2000 to 2000 year,near the water and mud was basically stable,because of Bi Jia mountain region in recent years economic and tourism development,the rise of sea level,even the island bar due to the rise of the mountain have varying degrees of impact related to it.In 2010 year due to the relevant departments of the coastal defense built around the dam,the coastline and area reduction rate very slow.
