The samples collected from a karst hilly area in central Guizhou were analyzed to effect of different land-use patterns(forest land

shrub land

shrub-grass mixed land and cultivated land) on environment of soil

runoff water and shallow ground water.The results showed that with the evolvement of land-use patterns from forest land

shrub land

shrub-grass mixed land to cultivated land

content of the organic matter

the available nitrogen

the available phosphorus

the available potassium

the exchangeable calcium and the exchangeable magnesium were obviously decreased

in contrast

content of the lay particles increased

and the quality of soil began to decrease.Content of the organic matter of the cultivated land was lower compared with forest land and grass land.The concentration of SO2-4

NH 4

PO3-4 and COD was obviously higher in the runoff water from the cultivated area than the forest land and grass land

and the concentration of SO2-4

NH 4

NO-3

PO3-4 and COD in shallow groundwater was also obviously increased.These results demonstrated that the quality of groundwater was some extent decreased with evolvement of land-use patters from the forest land to the cultivated land.
