壳斗科植物以它分布广、经济价值高、生态效益显著等特点在农林业生产中占有很重要的地位。但是,由于过去有关陕西省壳斗科分类与分布的资料少而分散,且种类资源不清,一些学者对种类命名上也有不同看法等等,因而在理论与实践上均造成了一些困难。为了弄清本科植物在陕西的分类与分布,澄清种类和命名上的一些混乱,我们自1981年以来,又作了较为全面系统的调查研究。所得结果,除部分内容已先后发表于《植物研究》1984年4卷4期及《西北植物学报》1986年6卷1期外;本文内容着重报导对陕西产壳斗科树木种类名称的订正、发表一些新组合、一个新变种及陕西省的不少新分布记录等。内容如下:
Fagaceae plants with its wide distribution, high economic value, significant ecological benefits and other characteristics in the production of agriculture and forestry occupy a very important position. However, due to the small and scattered information on the classification and distribution of the Fagaceae in Shaanxi Province and the unclear species and resources, some scholars have different opinions on the nomenclature of species. Therefore, some difficulties have been caused both in theory and in practice. In order to understand the classification and distribution of undergraduate plants in Shaanxi, to clarify some of the chaos and naming, we have made a more comprehensive and systematic investigation since 1981. The results obtained, except some of the contents have been published in the “Plant Research” 1984 the fourth volume 4 and the “Northwest Botanical Garden” 1986 the 6 volume 1 period; Published some new combinations, a new variant and many new distribution records in Shaanxi Province. The content is as follows:
