重庆市城区园林土壤质量现状研究

Quality of Landscape Soil in Urban Area of Chongqing City

文章通过对重庆市渝中区、沙坪坝区、江北区、南岸区等主城六区的道路、街旁绿地土壤养分、理化性状的测试分析,对园林土壤质量进行了综合评价。结果表明,重庆主城区市街绿地土壤总体质量不高,具体表现为有机质含量普遍偏低,土壤不缺钾,轻度缺氮,磷素极缺;土壤中的建筑垃圾使其保水保肥能力较差,部分土壤发生碱化和盐渍化。

Quality of landscape soil was assessed by analyzing physicochernistry property and nutrient status in greenbelt soils of urban areas in Chongqing City. Results showed that the soil quality was poor, with low content of organic matters, indeficient in potassium, lightly deficient in nitrogen and highly deficient in phosphorous. Construction waste landfill in soil lead to poor capacity of water and nutrient preserving, some of soils were alkalization and salt-affected.
