Five typicalland use types were chosen in the representative environmental immigrant region of Northwest Guangxi

China. Soil organic matter (SOM) and total and available nutrient contents were analyzed in the surface soil layer (0) 20cm). Results showed that in terms of the coefficient of the variation (CV) of soil nutrients

the contents of SOM

total N(TN)

total P(TP)

total K(TK)

available N(AN)

and available K(AK) had a moderate variability(0.1V1.0)

except that available P(AP) content had a high variability(CV1.0). In general

SOM and TN contents were in a higher level

AN and AP contents were in a moderate level

TP and AK contents were in a low level

and TK content was in a lower level.Land use had an important effect on the change in soil nut rients. SOM

TN

and AN contents had a high level in shrubland and grassland and a moderate level in dry land and or char dland. SOM

TN

and AN co ntents had a high

moderate

and low levels in seco ndary forest land

respectively. TP

TK

A P

and AK contents had low and lower levels in five land use types except that AP had a moderate level in dry land and orchar dland. Land use change after immigration did not lead to obv io us soil deg radat ion due to effective soil and water conserv ation measures

but P and K nutrients were increased.
