摘　　要：为了给经营管理城市人工林提供依据,采用分层数量调查与种群动态分析方法,研究了哈尔滨城市落叶松、白桦、水曲柳、胡桃楸、黄波罗和樟子松人工林群落的自然演替趋势,结果表明:落叶松林将演替为家榆、黄波罗和水曲柳占优势的硬阔叶混交林;白桦林将演替为水曲柳和黄波罗占优势的硬阔叶混交林;水曲柳林将演替为糖槭、水曲柳和黄波罗占优势的硬阔叶混交林;胡桃楸林将演替为水曲柳和胡桃楸占优势的硬阔叶混交林;黄波罗林将演替为家榆、水曲柳占优势的硬阔叶混交林;樟子松林将演替为水曲柳、蒙古栎、黄波罗占优势的硬阔叶混交林。A survey was conducted to study the natural succession trends of six kinds of plantations in Harbin City by the methods of stratification quantity survey and population dynamic analysis, in order to probe the near-natural management modes and provide scientific foundation for managing urban plantations. Results showed that Larix gmelinii plantation would develop to the deciduous broad-leaved forest dominated by Ulmus pumila, Phellodendron amurense and Fraxinus mandshurica ; Betula platyphylla plantation to the forest dominated by F. mandshurica and P. amurens ; F. mandshurica plantation to the forest dominated by Acer negundo, F. mandshurica and P. amurense; Juglans mandshurica plantation to the forest dominated by F. mandshurica and J. mandshurica; P. amurense plantation to the forest dominated by U. pumila and F. mandshurica; Pinus sylvestris var. mongolica plantation would transferred into the forest dominated by F. mandshurica, Quercus mongolica and P. amurense.
