  • Comprehensive evaluation of soil chemical and biochemical fertility under different vegetations (broadleaved forest, mixture of broad leaved and coniferous trees, Pinus massoniana, Cunninghamia lanceolata) were conducted using fuzzy mathematics and multiple statistics principle. It is found that the integrated chemical and biochemical fertility ranged as following order: broadleaved mixture Pinus massoniana Cunninghamia lanceolata (integrated fertility index for 0-,20 cm horizon were 0.741 2, 0.579 6, 0.479 8 and 0.347 6 respectively).The result of integrated fertility evaluation is consistent with single factor of fertility evaluation, but it is more convincible.
