Abstract:
1. A method for quantifying a plant resource using a GIS (Geographic Information System), comprising: a first step in which a sample group is extracted from mother groups having a plurality of distribution maps having a plurality of environment factors as attribute data, each environment factor including an IMI (Integrated Moisture Index) obtained through a GIS preprocess, so that a first relative table between a plant resource real measurement value of the sample group and an environment factor real measurement value is formed; a second step in which a second relative table is formed for thereby obtaining a relative model formula between the plant resource real measurement value and the environment real measurement value with respect to a certain species of a plant by relating the first relative table with a statistic analysis program; and a third step in which a plant resource estimation distribution map of the mother group having a plant resource estimation value as an attribute data is formed by relating the second relative table with the distribution map of the mother group and overlapping the distribution maps, whereby the IMI is obtained through four factors as formed of Hillshade, Flow accumulation, Curvature, and available water-holding capacity indicating soil factor; the IMI is computed based on the following formula 1; IMI=(h.times.W1)+(f.times.W2)+(c.times.W3)+(t.times.W4) where h represents the value of hill shade, f represents the value of flow accumulation, c represents the value of curvature, t represents the value of total available water-holding capacity, W1 represents moisture weighting value with respect to the hill shade, W2 represents moisture weighting value with respect to flow accumulation, W3 represents moisture weighting value with respect to curvature, and W4 represents moisture weighting value with respect to total available water-holding capacity.
