2011-07-22Impacts of Understory Management on Soil Respiration in Subtropical Native Forest PlantationThe effects of forest management on soil respiration in forest plantations are crucial to both our understanding and management of global carbon flux. In newly established mixed plantations of native species,understory plants can reach as high as 1 m and cover most ground surface in southern China. The study was conducted at Heshan Hilly Land In... The effects of forest management on soil respiration in forest plantations are crucial to both our understanding and management of global carbon flux. In newly established mixed plantations of native species, understory plants can reach as high as 1 m and cover most ground surface in southern China. The understory vegetation removal can reduce t...Read More -

2011-06-20The Uncertainty Determination of Emergy Analysis ModifiedThe conflict between environmental protection and further economic development is becoming a much serious problem in front of human being nowadays. Furthermore,they may be also useful in quantifying the uncertainty in ecosystem models and scaling up or down in ecological studies The results of this study will contribute greatly to the uncertaint... The conflict between environmental protection and further economic development is becoming a much serious problem in front of human being nowadays. To realize human being’s sustainable development, some scientific methods are firstly required to objectively evaluate the real wealth，including both economic and environmental aspects. Emergy theo...Read More

2011-06-07Different Management Practices Have Important Influences to Emission of Soil Greenhouse Gases in Plantation EcosystemsCO2,CH4 and N2O are all important greenhouse gases,which mainly come from soil of forest ecosystems. At present,it is a highlight to research mechanisms of greenhouse gases from forest soil. To determine the effects ofunderstory removal and Cassia alata addition on emission of soil greenhouse gases,Dr. The fluxes of soil CO2 stay at a high level...

2011-06-03Subtropical Plantations are Large Carbon Sink: Evidence from Two Monoculture Plantations in South ChinaForest plantations occupy approximately 264 million ha worldwide,which support the increasing local and global demands for wood and have been considered as potential fast-response carbon sinks that may mitigate the rise of atmospheric CO2 concentrations. Moreover it is necessary to assess the effects of corrections for disturbances of soil tempe... Forest plantations occupy approximately 264 million ha worldwide, which support the increasing local and global demands for wood and have been considered as potential fast-response carbon sinks that may mitigate the rise of atmospheric CO2 concentrations. In China, the area of plantations is nearly 62 million ha because of large-scale reforestat...Read More

2011-05-26Tissue Culture on Energy Plant Euphorbia tirucalli Achieves SuccessThe genus Euphorbia includes succulent shrubs distributing in tropical and subtropical regions of the world. These plants increase their biomass promptly in semi-deserts. Terpenoids and sterols in plants are also industrially important chemical sources as vitamins,steroid compounds,insecticides,and anticancer drugs Application of information to ... The genus Euphorbia includes succulent shrubs distributing in tropical and subtropical regions of the world. These plants increase their biomass promptly in semi-deserts. Euphorbia plant cells accumulate sterols, di- and tri-terpenoids. The major components of Euphorbia latex are triterpenes; cracked or fermented latex can be used as fuel. Terpe...Read More
