Biomass and efficiency of radiation utilization in Erythrophleum fordii community
|
Abstract:
The biomass and leaf area index( LAT )studied in Erythrophleum fordii community in Dinghushan were 568.172t/hm 2 and 27.8025m 2/m 2 and they were higher compared with Cryptocarya chinensis community distributed widely in this region.CO 2 infra red analysis method was used to measure both photosynthesis rate and respiratory rate.The productivity and efficiency of radiation utilization were calculated.The results show that the gross primary productivity was 24970kJ/m 2 ·a,the utilizati...
