The objective of this study was analysis of two methods of land suitability classification for wild edible green.
One method was Maximum limiting factor method (MLFM) and the other was Multi-regression method
(MRM) for land suitability classification for wild edible green. The investigation was carried out in
Pyeongchang, Hongcheong, Hoeingseong, and Yanggu regions in Korea. The obtained results showed that
factors related to the decision classification of the land suitability for wild edible green cultivation were land
slope, altitude, soil morphology and gravel contents so on. The classification of the best suitability soil for wild
edible greens were fine loamy (silty), valley or fan of soil morphology, well drainage class, B-slope (2∼7%),
available soil depth deeper than 100cm, and altitude higher than 501m. Contribution of soil that influence to
crop yields using Multi-regression method were slope 0.30, altitude 0.22, soil morphology 0.13, drainage
classes 0.09, available soil depth 0.07, and soil texture 0.01 orders. Using MLFM, area of best suitable land
was 0.2%, suitable soil 15.0%, possible soil 16.7%, and low productive soil 68.0% in Hongcheon region of
Gangwon province. But, area of best suitable land was 35.1%, suitable soil 30.7%, possible soil 10.3%, and
low productive soil 23.9% by MRM. There was big difference of suitable soil area between two methods
(MLFM and MRM). When decision classificatin of the land suitability for wild edible green cultivation should
consider enough analysis methods. Furthermore, to establishment of land suitability classification for crop
would be better use MRM than MLFM.
