According To "3S" Technical Sum Benefit Studying Of The Characteristic And Space Abutment Characteristic Of The Ejina Oasis Vew Structure And Form

Along with the development and mature of"3s"(Remote sensing,Geographical Information system,Global positioning system)technichl in 21 centuries. make use of the 3s technique to carry on the research of landscape ecology gradually becomes the new method and new thinking in landscape system analysis. Remote sensing can provide information about spectrum and spatial resolution in different times. In Geographical Information system , can carry on the collection,management,analysis and output on the data from Remote sensing. The Global positioning system can be used to take investigate into the field survey and verify the data mentioned above.Study to beard's wood's view qualitative analysis and evaluation currently of more, but for sum benefit fixed amounts such as the Ejina Oasis view structure and form and space abutment characteristic etc. of analysis and evaluation less. This text with sum benefit Ejina Oasis for study district, adopt a"3S"technique and compute a sum benefit Ejina Oasis each view of oasis the basic characteristic of the type meteredly, beg a sum benefit Ejina Oasis broken up degree index number, enrich a degree index number, diverse sex index number andwoodland,lawn,farmland, residents and use ground thus, water oasis the view type and hungriness turn view type sand ground, salt such soil and Gobi desert of space abutment characteristic, get a sum benefit Ejina Oasis view structure and form thus is a typical view uality-gallery-spot piece structure and higher broken up turn, diverse lower sex and rough quality characteristic. Ejin oasis in the forest landscape by the type of the Gobi desert pose the greatest threat, followed by the threat of salinization, desertification threat to smaller, grass by the salinization of the biggest threats, the threat of the Gobi desert followed by the threat of desertification smaller , The salinization of arable land pose the greatest threat, the threat of the Gobi desert followed by the threat of desertification smaller sites by residents of the Gobi desert pose the greatest threat, the threat of salinization and desertification threat to smaller, the waters of the threat of the Gobi desert The largest, followed by the threat of salinization, desertification threat smaller.
