城市绿地土壤退化及防治技术的研究与实践——以天津市文化中心为例

Study and Practice of Urban Green Space Soil Degradation and Control Techniques:Take Tianjin Cultural Center for Example

本文以天津市文化中心景观绿地为例,分析了城市绿地存在土壤盐碱化、养分贫瘠化、压实板结化、污染毒化、生物环境恶化的潜在威胁,对新建绿地土壤采用全面培育和保护技术,即建设栽植土床、实施暗管排盐、增施有机肥和改良剂,并提出城市绿地土壤退化预警对策和建议。

In this paper, taking green landscape of Tianjin Cultural Center for example, urban green space presence potential threat of soil salinization, nutrient depletion, compaction compaction, pollution poisoned, the deterioration of the biological environment were analyzed. For new green soil, comprehensive cultivation and protection technology was used, namely the construction planting bed soil, implementation of underground pipe row salt, exert organic fertilizers and amendments. And urban green space soil degradation early warning measures and suggestions were proposed.
