| 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。 |

| Abstract: |
| 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. |
