Biotope Evaluation and its Classification Considering Urban Ecological Status: Focused on Cheongju City
This study has intended to evaluate and type classification of biotope considering the urban ecological status in
Cheongju City. This study consisted of the following three steps. First, we corrected greenness grade to calculate NDVI
through satellite images (Quickbird) of Cheongju city. Second, we build thematic map of landscape, land-use, vegetation and
land cover. Finally, we set up the ecological status grade to classify thematic map of 'land/human effect grade' and
'ecological habitat total grade' for biotope evaluation in Cheongju city using indicators process and matrix technique. This
study has found the following results: 1) land/human impact grade was classified into five classes to mix land-use and
landscape grade, 2) we suggest alternatives to compute comprehensive ecological habitat grades through summary up
habitability grades according to greenness grades and 3) we classified sixty-two biotope types. This process calculates two
alternative biotope grades. We found out the fifth grade (28.3%) is 1.5 times higher than the first grade (18.3%) and the
second grade (2.1%) is the lowest total grade.
