This study is to find out the correlation between plant groups and environmental gradient in the native grassfild near Kang Nam Express Terminal from August 26 through september 15, 1977 for samples collection. The correlations among plant species were calculated by using the method of ordination, and the various relationships among soil environmental gradients were grouped by means of correlation coefficient. As a result, both the species and the soil environmental factors could be subdivided into four groups, and the four groups of the native grassfield were turned out to be correlated with the four groups of soil environmental factors. The first plant group(Panicum dichotomiflorum, Chenopodium album, Bidens frondosa, Humulus japonicus, Echinochloa macrovotbi, Rorippa sublyrata, Polygonum longisetum, Rumex japonicus, Alopeculus amurensis, Potentilla fragarioides, Centipeda minima, Beckmannia erucaeformis) was formed in the relve 1-10 reagions, where organic matter by Turin's method, Total N, Exchange Ca and total of Exchange K, Na, Mg, Ca were abundent. The second plant group(Digitaria sanguinalis, Paltulaca oleracea, Echinochlea macrocorvi, Cyperus amuricus) was formed in the relve 11-18 reagions, where Exchange Ca and total of Exchange K, Na, Mg, Ca were a little but Exchange Al and sand were aburdent. In relv'e 19-20 reagions, with much of Exchange Ca, total of Exchange K, Na, Mg, Ca, pH and a little Exchange Al, was found the third plant group(Pycreus sanguinolentus, Cyperus amuricus, Luawigia prostrata, Echinochloa echinata, Polygonum thunbergii, Salix glandulosa seedling) The fourth plant group (Cassia nomame, Polygonum perfoliatum, Setaria viridis, Glycine ussuriensis, Lactuca indica, setaria glauca, Artemisia capill airis, Artemisia asiatica, Calamagrostis arundinacea, Kummerowia striata, Denothera odorata, Artemisia japonica, Carey laceolata) was formed in relv'e 21-25 reagions, where organic matter by loss on ignition, Exchange Mg and Maximum water holding capacity were abundent but sand was a little. And than, the vegetation group were formed by using the method of ordination, could be found out the reason by grouping environmental factors of soil, by means of correlations coefficient. Exchange Ca and total of Exchange K, Na, Mg, Ca were abundent. The second plant group(Digitaria sanguinalis, Paltulaca oleracea, Echinochlea macrocorvi, Cyperus amuricus) was formed in the relve 11-18 reagions, where Exchange Ca and total of Exchange K, Na, Mg, Ca were a little but Exchange Al and sand were aburdent. In relv'e 19-20 reagions, with much of Exchange Ca, total of Exchange K, Na, Mg, Ca, pH and a little Exchange Al, was found the third plant group(Pycreus sanguinolentus, Cyperus amuricus, Ludwigia prostrata, Echinochloa echinata, Polygonum thunbergii, Salix glandulosa seedling) The fourth plant group (Cassia nomame, Polygonum perfoliatum, Setaria viridis, Glycine ussuriensis, Lactuca indica, setaria glauca, Artemisia capill aris, Artemisia asiatica, Calamagrostis arundinacea, Kummerowia striata, Denothera odorata, Artemisia japonica, Carey laceolata) was formed in relv'e 21-25 reagions, where organic matter by loss on ignition, Exchange Mg and Maximum water holding capacity were abundent but sand was a little.
