Responses of Energy Accumulation and Allocation in Leymus Chinensis Communities to Different Habitats in the Songnen Grassland, China
The response mechanism of Leymus chinensis communities to different habitats in the Songnen grassland of China was studied from the viewpoint of community-level energy accumulation and allocation, by measuring calorific values at every 10 cm above and belowground. Patterns of energy allocation differed in the three habitats: sown, mown, and grazed plots. The energy production of the three habitats was highest in sown plots, followed by mown and grazed plots in declining order. The varying patterns of energy allocation may reflect strategies of long-term adaptation to the varying conditions in the three communities. The results provided evidence that different habitat conditions, induced by different intensities of anthropogenic influences, have profound impacts on energy accumulation and proportional allocation in L. chinensis communities.
