Numbers are in ALaShan unita as projectiveThe application of ecological environment surveyIn thisAlong with the digital photogrammetry and calculators sensing technology rapid development, production application digital remote sensing image geographic information spatial data products, digital is mature in land management, projective as urban planning, forestry survey industries department a wide range of applications, using a digital satellite images, apply modern aerophotogrammetry technology, production Numbers are image-disposal method, and thus the data, conduct environmental ecology investigation, can solve past in the short term because of large of comprehensive investigation difficult to realize the situationThis paper ALaShan au to ecological environment survey as the research object, using in 1996, 2000, 2002 three year's TM, ETM multi-spectrum data and 15 meters, according to data full-color band environmental investigation application modern image processing method, image fusion, video and image classification corrective ALaShan unita ecological characteristic problem with research. The main content of the study are as follows:1.
