摘　　要：油松是我国北方山区重要的造林树种,具有极高的经济和生态价值,在北京市的城市绿化中也有广泛应用。但受多种原因影响,北京市部分油松存在生长衰弱的现象。以油松为研究对象,从不同角度分析了北京市油松生长衰弱的主要原因,并基于病虫害防治方法、油松栽培技术、减少污染物排放、土壤环境技术、合理的管理与经营方法等方面提出了油松复壮措施及栽培技术方案。结果表明:北京市油松生长衰弱主要与病虫害、移栽手段、城市发展、极端天气等因素有关;案例分析结果也表明,采用文中所提出的油松复壮措施可有效缓解油松的红化现象,复壮效果显著。Pinus tabuliformis,a significant afforestation tree species in the northern mountainous regions of China,possesses high economic and ecological value and is widely used in urban greening in Beijing.However,due to various reasons,there is a phenomenon of weakening growth in some Pinus tabuliformis trees in Beijing.In this study,focusing on Pinus tabuliformis,the main causes of weakening growth in Beijing's Pinus tabuliformis are analyzed from different perspectives.Based on methods for disease and pest control,cultivation techniques for Pinus tabuliformis,reduction of pollutant emissions,soil environment techniques,and appropriate management and operation methods,measures and cultivation techniques are put forward for revitalizing Pinus tabuliformis.The research results indicate that the weakening growth of Pinus tabuliformis in Beijing is mainly related to factors such as diseases and pests,transplanting methods,urban development,and extreme weather.The case analysis results demonstrate that the revitalization measures proposed in this study can effectively alleviate the redness phenomenon in Pinus tabuliformis and have a significant revitalization effect.
