It could be ascertained that the natural storage capacity of H.serrata was 413.1 t; based on this figure and the factor of manpower collection,the theoretical exploitation capacity was 20.6 t. However,the large-scale exploitation should not be feasible because of their scattering status and relative concentrated distribution areas in the natural reserves and scenic spots.

As the light intensity decreased,the single leaf area increased and leaf mass per area(LMA)decreased. The root tuber biomass was the highest under 30% of light intensity.

Different species pairs varied greatly in their responses to the flooding disturbance. It showed that the inter-specific co-variance relations were not only dependent on environmental perturbation or disturbance factors,but also on the biological and ecological properties of the species that comprised the species pairs.
