The types of soil degradation in Fujian province were analysed,the regional differenti ation of
soil erosion, soil pollution and soil impoverishment were discussed, and to develop
sustainable agriculture and strengthen the conservation of soil resource were presented. The
research results show that: (1)The average contents of heavy metals such as Cu, Zn, Cd, Ni, Pb,
Hg and As in polluted soil are 0.8, 1.0, 1.9, 0.9, 1.3, 1.2 and 0.2 times as large as that in
nonpolluted soil. (2) There are evident differences for cultivated land polluted by heavy metals
in different landuse types. (3) The increasing year after year for amount of fertility and farm
chemical in soil has influenced agricultural production. (4) Soil erosion area has been
developing since 1956, and the soil erosion intensity has evident differences in different land
use types. It is the heaviest for soil erosion in the mine land and the capital construction land,
heavier in nongrown forest land and tea garden, and light in grass land and forest land. (5) The
nutrient content of cultivated land especially the organic matter content is low greatly than that
of natural land, and the content of N will decrease after soil had been cultivated. The shortages
of soil nutrients in farmland are serious on the point of regional differences for the short of N, P
and K.
