摘要
根据卫星遥感图象(MSS4,5,7)的解译理论和方法,利用美国地球资源技术卫星多光谱扫描的图象(MSS4,5,7),经纠正放大,合成1/20万假彩色图象(MSS4,5,7).配合航空象片、地形图和野外的海岸线调查,解译、测量出福建省陆地岸线长3041.5km.岛屿岸线长为1471.6km.经验证认为,MSS4,5,7假彩色图象所解译测定的岸线长的数据可靠,可为进一步开发利用福建海岸带资源提供科学依据.
According to the interpretation theory and its way of the sate- llite remote sensor images,1/2×10~5 composite false color images(MSS 4, 5,7)are composed after rectifying and magnifying American earth resources technology satellite-(1,2,3)and its multispectrum scan images.Through the use of aerophotographs and landforms and a field survey of the coastline of Fujian.We have interpreted,measured and mapped out the length of Fujian coastline:3041.5 km and that of islands coastline:1471.6km respec- tively.Computional check shows that the data obtained form interpretation and determination of ecastlire by MSS 4,5,7 false color images are reliable.This provides a scientific basis for the development and utilization of Fujian coastline resources.
