长江南京段堤岸立地条件分析及风景林营建技术

对长江南京段堤岸林地土壤和林种类型进行了调查和分析,结果表明:土壤质地为粉砂壤或壤土,有机质与氮磷含量较高,现有的杨树等树种生长状况良好,具备营造高质量景观林的立地条件。在此基础上,进一步从环境条件特点、树种选择、结构配置、季相变化等方面探讨了适用于长江下游沿江城市的风景林营建技术,为长江下游沿江城市营建近自然堤岸风景林提供了理论依据。
The site condition and stands in the embankment of Nanjing region of Yangtze River were investigated and analyzed. The results showed that the soil texture was silt loam or loam, contending high organic matter, nitrogen and phosphorus. Poplar and other trees growing well indicated that the site conditions were suitable to establish high-quality landscape forests there. Based on the former analysis, the silviculture techniques for establishment of scenic forest was generated from the aspects of environmental condition, species selection, structural arrangement and seasonal color changes to meet the city's demand of building scenic forest along the Yangtze River
