在日本北部北海道岛的一个古老的云杉-冷杉森林中研究了森林地面微场地条件和树苗的建立。大量的树苗生长在粗糙的木质碎片（CWD）上，从腐烂等级 III（表明中度腐烂的等级）到等级 V（最严重的腐烂等级）。树苗的高度等级分布表明，云杉（Fr. Schm.）Masters 和云杉（Sieb. et Zucc.）Carr 的招募。 CWD 上的幼苗开始出现 II 级腐烂，并且大部分仅限于 CWD III 级腐烂。 Abies sachalinensis (Fr. Schm.) Masters 幼苗也喜欢在 CWD 上生长，但对大多数微场地具有广泛的适应性。尽管 CWD 起到了合适的苗床的作用，但 CWD 的水提取物呈酸性，并且矿物质营养浓度相当低。树苗的建立不一定需要微场地中高水平的养分含量。尽管森林地面大部分被 CWD 覆盖，面积为 2056 平方米...
Forest floor microsite conditions and tree seedling establishment were studied at an old-growth Picea-Abies forest in Hokkaido Island, northern Japan. Tree seedlings were established abundantly on coarse woody debris (CWD) from decay class III, a class indicating moderate decay, to class V, the most advanced decay class. The height-class distribution of tree seedlings indicates that the recruitment of Picea glehnii (Fr. Schm.) Masters and Picea jezoensis (Sieb. et Zucc.) Carr. seedlings on CWD started on decay class II and was mostly restricted to CWD decay class III. Seedlings of Abies sachalinensis (Fr. Schm.) Masters also favored establishment on CWD but had a wide adaptability to most of the microsites. Although CWD functioned as a suitable seedbed, water extracts from CWD were acidic and had quite low mineral nutrient concentrations. Tree seedling establishment did not necessarily require high levels of nutrient content in microsites. Although the forest floor was largely covered by CWD, with 2056 m2...
