Abstract
The study on the energy and nutrient characteristics of Carex lanceolata, a dominant companion species in different plant communities in Ziwuling forest area of Loess Plateau showed that the ash free caloric values of the aboveground and underground parts of the species tended to decline in the communities experienced different successional stages. The aboveground part of C. lanceolata had the highest ash free caloric value in Sophora viciifolia community and the lowest in Hippophae rhamnoides community. The underground part of C. lanceolata had the highest ash free caloric value in S. viciifolia community and the lowest in Quercus liaotungensis community. The aboveground part of C. lanceolata had a remarkably higher caloric value than its underground part, and the underground part appeared to extremely significantly differ in gross and ash-free caloric values among different communities. The caloric value of C. lanceolata varied greatly in the communities going through their early successional stages (S. viciifolia, H. rhamnoides, Populus davidiana and Betula platyphylla communities), and less greatly in the communities experiencing their later successional stages (Pinus tabulaeformis and Q. liaotungensis communities). There was a significant positive correlation between the gross caloric value and the C/N ratio in the underground part of C. lanceolata.
