The results of the study are summarized as follows : 1. The number of species found out from the forest resources inventory was 60. The percentages of the number of trees by species were 14% of Leucaena leucocephala, 13% of Schima wallichii, 10% of Cinnamomum Japonicum, 8% of Pinus luchuensis, 5% of Symplocos lucida, 4% of Cinnamomum doederleinii, 4% of Aridisia sieboldii, 3% of Ficus virgata, 3% of Elaeocarpus sylvestris and 3% of Persea thunbergii. These 10 species which counted over 100 trees per hectare were about 67% of the whole of number of trees, and the remaining 33% was the other 50 species. 2. The estimated rates of error in the forest resources inventory were 8.6% of mean diameter breast high, 7.8% of mean tree height, 20.1% of number of tree per hectare, 15.4% of basal area per hectare and 19.0% of volume per hectare. The number of tree, basal area and volume per hectare were 4,246,8.8m^2 and 73.3m^2,respectively. The mean diameter breast high and mean tree height were 7.0cm and 5.1m, respectively. 3. Therefore, the important charactristrics of the forset resources in the central and southern parts of Okinawa Island are the variety of tree species. 4. The ethnobotanical classification of forest trees by use were 45 species of Timber, 31 species of fuel, 13 speciess of food, 11 species of drug, 10 species of fertilizer, 9 species of forage, 8 species of dye, 5 species of oil and 3 species of fiber in the first group, and 36 species of tard, 29 species of wind, 14 species of tide and 14 species of street in the second group. 5. The classification of genetic resources of forest trees were all the unutilized gentic resources of B_2 type. The number of special plant coummunty of C type was 15.","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":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3824"}]},"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.
