摘要
根据宁合高速公路陇西互通立交环境工程建设的系统研究成果 ,研究分析评价了陇西立交绿化区扰动土壤理化性质、恢复植被对扰动土壤的水保与改土效应、自然与人工恢复植被的生物量与养分积累、恢复植被改良扰动土壤性质、恢复植被物质流。在此基础上对扰动土壤生态管理的原则进行了探讨和论证。
Based on the research achievements of the Longxi Interchange Environmental Engineering Project on Nanjing-Hefei Expressway in Anhui and Jiangsu province, this paper analyzes the physical and chemical characteristics of the disturbed soil in afforestation area of Longxi Interchange. It also analyzes and evaluates the impacts of the restoration cover plants on the water and soil conservation of the disturbed soil and the effects to improve the soil quality. In this paper, it also analyzes the quantity and the nutrient accumulation of the restoration cover plant by nature and manual, the characteristics of the improved disturbed soil of the restoration cover plant, as well as the logistics of the restoration cover plants. It discusses the principles of the ecological management of the disturbed soil.
