Form-1E FY2010 Strategic Japanese-Chinese Cooperative Program on “Climate Change” Title of Cooperative Research Project Japanese Research Leader Chinese Research Leader Proposed Period of Cooperative Research Project Form-2E Summary Microbial function Forest soil Acid rain Keywords N deposition Litter decomposition Soil enzymes Microbial respiration 1. To comparatively evaluate the sensitivity of forest litter decomposition and soil decomposing enzymes under different intensity of acid rain and atmospheric N deposition in forests between China and Japan. 2. To reveal the effects of climate change (different intensity of acid rain and atmospheric N deposition) on the composition of Goals micro-decomposer and the rates of microbial respiration in forests between China and in Japan. 3. To determine the sensitivities of the fluxes of greenhouse gas CO2 from soil microbial respiration under different intensity of acid rain and atmospheric N deposition in forests between China and Japan. 1. Forest sites will be chosen both in Japan and China. The more similar sites are, the better the chosen is. Cyclobalanopsis glauca (Thunb.) Oerst leaves will be considered as candidate
