摘要：
Lantana camara shrubland is compared with the adjacent Quercus leucotrichophora and Pintis roxburghii forests to understand changes occurring in net primary productivity and nutrient cycling, as a consequence of degradation of these forests. The total net primary productivity of Lantana camara shrubland was 17 t ha-1 yr-1, which is similar to the values reported for forests: 16 - 21 t ha-1 yr-1. Total nutrient content (N, P) in the soil in the L. camara shrubland: 2932 kg ha-1 N and 111 kg ha-1 P, was lower than that of the forest soils.
