2011年東北地方太平洋沖地震津波の被害を受けた宮城県名取市閖上浜における海岸クロマツの生長履歴と表層土の粒度特性 Past grown record of coastal Japanese black pines at Yuriage beach, Miyagi Prefecture, which suffered from the damage by the 2011 Tohoku tsunami and the characteristics on soil samples collected in this area 1000010301392 寺本, 行芳 テラモト, ユキヨシ TERAMOTO, Yukiyoshi 1000000353623 岡, 勝 オカ, マサル OKA, Masaru 1000060041670 下川, 悦郎 シモカワ, エツロウ SHIMOKAWA, Etsuro open access 2011年東北地方太平洋沖地震津波 海岸林 閖上浜 吹上浜 The purpose of this research was to identify past grown record in coastal Japanese black pines as well as grain size characteristics and pH of surface soil layer following damage from the 2011 Tohoku tsunami, and to compare them between Yuriage beach in Miyagi Prefecture and Fukiage beach in Kagoshima Prefecture. We placed one transect (A) perpendicular to the shoreline from the top of the fore-dune to the inland area in Yuriage beach and two transects (B and C) perpendicular to the shoreline from the top of the fore-dune to the inland area in Fukiage beach. Inland areas of each transect consisted of Japanese black pine forests. Transect A included a forest area that had been severely damaged during the 2011 Tohoku tsunami. Transect B included a forest area that sustained little damage, and transect C was in an area that had been severely damaged by pine wilt disease. The mean annual index value of tree ring width of coastal Japanese black pine at Yuriage beach was greater than that at Fukiage beach. The pH values of the surface soil layer in the black pine forest at Yuriage beach were greater than those at Fukiage beach. The mean value of the median diameter of surface soil particles at Yuriage beach was greater than that at Fukiage beach. The ratio of coarse sand in the surface soil particles at Yuriage beach was greater than that at Fukiage beach, and the ratio of fine sand in surface soil particles of Yuriage beach was smaller than that of Fukiage beach. Based on the measured soil parameters and tree growth response, we concluded that the growth environment of the coastal forests at Yuriage beach following the damage sustained during the 2011 Tohoku tsunami was more severe than that at Fukiage beach. 鹿児島大学 Kagoshima University 2013-03-01 jpn departmental bulletin paper VoR http://hdl.handle.net/10232/20262 https://ir.kagoshima-u.ac.jp/records/2819 13449362 AN10592752 鹿児島大学農学部演習林研究報告 Research bulletin of the Kagoshima University forests 40 31 38 https://ir.kagoshima-u.ac.jp/record/2819/files/AN10592752_v40_p31-38.pdf application/pdf 1.8 MB 2016-10-27 2013-03-01
