Selective woodland exploitation for charcoal production. A detailed analysis of charcoal kiln remains (ca. 1300–1900 AD) from Zoersel (northern Belgium)

A detailed study of charcoal burning activities has been made for the Zoersel forest (Northern Belgium) based on an inventory of charcoal kiln remains, the analyses of wood charcoal and other charred botanical macroremains and radiocarbon dating of 10 of these kilns. Age determination of the youngest kilns was refined by dendrochronological analysis of trees growing on top of these kiln sites. The results show that, although many kilns were found, charcoal was produced in Zoersel only at certain moments during late and post-medieval times suggesting that charcoal burning was not a part of the regular management practice of these forests. The wood used for the production of charcoal mainly consists of taxa of alluvial (alder) forests while the kilns are situated on sites that currently are rather dry, with an oak dominated vegetation. For the older kilns, this contrast could be explained by an important change in local soil conditions. The younger kilns may be related to the conversion of alder woodland to grassland in the lower parts of the domain, with the kilns being constructed in the nearby dryer woodland areas.     

辽金人的忠孝观

忠孝是中国古代伦理的重要内容 ,中国传统文化的组成部分。契丹、女真早期本无忠孝观念。辽金建立后 ,随着社会的发展 ,儒学的传播 ,统治者的倡导 ,民族的融合等 ,忠孝观念逐渐形成和发展起来。忠孝在辽金及后来元人那里 ,超越了民族、地区和国别的畛域 ,人们对外族、邻国、敌国乃至前朝的忠臣孝子同样表现出尊重和崇敬。 1 0 - 1 3世纪 ,忠孝已成为汉、契丹、女真、蒙古等各民族一致认同的伦理道德观念和行为规范 ,从而体现了中国传统文化的历史继承性和强大凝聚力。
