The litter accumulation on forest floor amounted, averagely, to 12.02t/ha in evergreen broadleaved forest, lower than that in Ryukyu pine forest, which amounted to 17.25t/ha. The leaf litter, branch litter, wood litter and (F+H) layer amounted for about 36%, 22%, 20% and 22% of the total litter accumulation, respectively. The litter accumulation was strongly affected by soil type or soil moisture. But, the effect of the stand structure over litter accumulation was complicated. The result from the investigation demonstrated that basal area, mean d. b. h. and density of stand appeared to have certain tendency to affect on litter accumulation. The mean ratio of (F+H) to L_l in evergreen broadleaved forest was 0.38,lower than that in pine forest, which was 0.73. The estimated decomposition rate of litter was very rapid as those in other forests in Japan.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3720"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
