上海市道路绿化带土壤改良效果分析——以桂江路绿廊(三期)土壤改良为例

Analysis of Soil Improvement Effects in the Road Greening Belt of Shanghai—Taking the Soil Improvement of the Guijiang Road Green Corridor (Phase III) as an Example

摘要: 生物多样性保护是全人类共同的使命，城市生物多样性是生物多样性的重要板块，绿地土壤健康是城市生物多样性的基石。本文以上海市徐汇区桂江路高压廊道(三期)绿化带为研究对象，基于该廊道绿化带土壤pH、EC、有机质等指标现状，以改善其土壤性状为目的，选择营养土、综合介质和果壳介质进行土壤改良，分析该绿化路段土壤添加介质后的改良效果，结果表明，土壤改良后，其pH、EC值、有机质含量均得以明显提高，特别是pH和有机质含量增幅显著。因此，土壤中增添营养土等改良介质能够显著改善城市道路绿化土壤性质，实践中，应依据分析土壤性状、结合实际开展改良措施，提高道路绿化质量，提升城市土壤生态文明意识，维护城市生物多样性。

Abstract: Biodiversity conservation is a common mission for all humanity, and urban biodiversity is an im-portant component of biodiversity. Soil health is the foundation of urban biodiversity. This article takes the green belt of the Guijiang Road high-voltage corridor (Phase III) in Xuhui District, Shanghai as the research object, and based on the current situation of soil pH, EC, organic matter and other indicators in the green belt, aims to improve the soil conditions by selecting nutrient soil, comprehensive medium and fruit shell medium for soil improvement. The effect of soil improvement after adding media to the green belt soil was analyzed, and the results showed that after soil improvement, the pH, EC value, and organic matter content were significantly improved, especially the pH and organic matter content increased significantly. Therefore, adding nutrient soil and other improvement media to the soil can significantly improve the soil properties of urban road greening. In practice, improvement measures should be carried out based on soil analysis and combined with actual conditions to improve the quality of road greening, enhance awareness of urban soil ecological civilization, and maintain urban biodiversity.
