ecological beneficial forest%compensation rate%emergy synthesis%Guangdong Province
To find out the feasible compensation rate for ecological beneficial forest, the ecological benefits such as fixation of solar energy, absorption of carbon dioxide, release of oxygen, and maintaining the global atmosphere balance, were evaluated with the employment of emergy synthesis for the ecological beneficial forest in Guangdong Province. The result showed that ecological benefit of the ecological beneficial forest in Guangdong Province was significant, and the emergy output value was 0.285 billion ($) per year. The emergy investment ratio (EIR) and environmental loading ratio (ELR) of ecological beneficial forest system were on a low level. More emergy should be input to the system in order to improve the utilization efficiency of resources. It was suggested that 136 ($)·hm-2 a-1 , i.e., 99 ($)·hm-2 a-1 for ecological benefit and 37 ($)·hm-2 a-1 for management expenditure, should be compensated at average level in Guangdong Province for the ecological beneficial forest.
