摘要
在福建省建瓯市温洋村,以1996年和2005年二期固定样地的森林资源连续清查数据为基础,结果表明,在相当长的一段时间内,乡村森林景观以锥栗速生林为主导,由于采伐迹地更新树种单一,导致原生硬阔林逐渐减少,森林景观要素组成趋于单一,并随着n→∞时,软阔林比例越来越大,几乎占据了整个乡村森林景观的80%以上,形成景观单一、大面积纯种林的生态系统。依据预测分析的结果,文章提出合理宏观控制的对策和建议,为乡村森林景观的可持续经营提供科学依据。
In Wenyang village of Jian＇ ou city of Fujian Prov. , according to forest resources sustainable check of permanent sample plot in year of 1996 and 2005,the results show that in quite long period of time, the Chinquapin fast-growing forest still occupies the dominant position. As the management did not work well and the felling mark has not been promptly renewal, the hard-broad leaved forest ecology forestry which suitable for the local climatic conditions has fell broad the danger,the forest landscape essential factor became simpler and simpler; with n→∞, the soft-broad leaved forest takes the important position more and more, its proportion almost holds 80% area of the whole forest landscape, as that the landscape ecosystem consist of pure forest. According to the analyzed result, the macro-control reasonable countermeasure is proposed, providing scientific bases for sustainable management of the rural forest landscape.
