It is critical to clarify the differences between the forest water cycle of C. japonica plantations and that of broad-leaved deciduous forests because as many C. japonica plantations in Japan have been converted from broad-leaved deciduous forests. This study examined the significance of the transpiration of a C. japonica plantation in winter using one-year heat pulse velocity (HPV) data. HPV would be linearly related to the canopy transpiration rate and was higher in summer than in winter, with a maximum in August. In January and February, March and April, and December, HPV was approximately 20, 70, and 40% of that in August, respectively. The relatively high HPV in March and April indicated that the forest water cycle of the C. japonica plantation during these months was quite different from that of broad-leaved deciduous forests in the same region in terms of transpiration","subitem_description_type":"Abstract"},{"subitem_description":"常緑林であるスギ人工林は日本でもっとも一般的な森林タイプのひとつである。日本のスギ人工林の多くは落葉広葉樹林を伐採して作られたものであり，このような土地利用変化の影響を考えるうえで，スギ人工林と落葉広葉樹林の水循環の違いを明らかにすることは重要である。本研究では，スギ人工林における冬の蒸散量の大きさについて，通年計測されたヒートパルスデータを用いて検討した。林分蒸散量と対応するヒートパルス速度は，夏に大きく冬に小さかった。ヒートパルス速度の月間値は8月に最大となった。1・2月，3・4月，12月におけるヒートパルス速度の月間値は，それぞれ8月の20%，70%，40%だった。このように3・4月においてヒートパルス速度は比較的大きく，蒸散から見た場合，この時期のスギ人工林の水循環は同地域の落葉広葉樹林の水循環と大きく異なることが示された","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"53752","nameIdentifierScheme":"WEKO"}],"names":[{"name":"小松,
