摘　　要：研究沿海城市人工湖沿岸带绿地土壤质量特征及影响因素,对沿海城市沿岸带绿地建设和管理技术提升具有重要意义。以上海滴水湖沿岸带绿地土壤为研究对象,通过现场调查,分析沿岸带绿地土壤理化性质以及不同剖面土壤特性,并选取滴水湖沿岸带裸地和上海中心城区绿地土壤为对照,分析植被以及不同地理环境对土壤质量的影响。结果表明:滴水湖沿岸带绿地土壤偏碱,EC值和有机质较低,土壤容重较大,土壤孔隙度和持水量较低,土壤质地以粉砂壤土和粉(砂)质黏壤土为主。表层土壤理化性质明显优于中层和深层土壤;沿岸带绿地土壤理化性质较裸地土壤好,较中心城区绿地土壤差。沿岸带绿地植被对土壤的改良作用显著,但受沿海地理环境影响,沿岸带绿地土壤质量易退化。Studying the soil quality characteristics and influencing factors of green space along artificial lakes in coastal cities is of great significance to the construction and management of coastal zone green space in coastal cities. Taking the green space soil along Dishui Lake in Shanghai as the research object, the physical and chemical properties of the green space soil along Dishui Lake and soil characteristics of different profiles were analyzed through field investigation. In addition, the bare soil along Dishui Lake and the green space soil in the central urban area of Shanghai were selected as the comparison samples to analyze the effects of vegetation and different geographical environments on soil quality. The results showed that the green space soil along the coastal zone of Dishui Lake was alkaline, with lower EC and organic matter,higher bulk density, lower pore content and water holding capacity. The soil texture was mainly silt loam and silty clay loam. The physical and chemical properties of the surface soil were obviously better than that of the middle and deep soil. The physical and chemical properties of the soil in the green space along the coast were better than that of the bare soil, but were worse than that of the green space soil in the central urban area. The green space along Dishui Lake has a significant effect on soil improvement, and the coastal green space soil quality is easy to degrade due to the influence of coastal geographical environment.
