火地塘位于秦岭中段南坡的腹地，锐齿栎林是该林区的主要森林类型之一。通过对本区锐齿栎林群落的野外调查，报道了组成该群落的植物种类１８３种，隶属于６０科，１３１属，并在此基础上对该群落区系特点作了较为详细的分析。表明：该群落区系具有明显的温带性质；该群落区系是奠基在秦岭古老植物区系的基础上，通过种间竞争，群落演替形成的；锐齿栎本身不是一个古老的类群，其出现的时间不会早于上新世。
Huodatang is located in the hinterland of the southern slope of the middle section of the Qinling Mountains. Sharptooth oak forest is one of the major forest types in this area. Based on the field investigation of the community of Quercus aliena forest in this area, 183 species of plants that belong to this group are reported, belonging to 60 families and 131 genera. On this basis, the characteristics of flora in this community were analyzed in detail. The results show that the fauna of this community has obvious temperate character. Based on the ancient flora of Qinling Mountains, this fauna is formed through interspecific competition and community succession. The oak is not an ancient group, It does not occur earlier than the Pliocene.
