为了对齐齐哈尔市居住区绿地土壤的理化性质进行分析,为城市居住区绿地土壤管理提供参考,试验选取齐齐哈尔市主城区6个具有代表性的居住区绿地分别采样,采用物理和化学方法测定了齐齐哈尔市居住区绿地土壤的理化性质。结果表明:齐齐哈尔市居住区绿地土壤容重略微偏大,土壤压实过紧,土壤中所含杂质较多,含水量少,孔隙度在正常范围之内,土壤碱性过大,有机质含量偏低,全氮、全钾含量中等偏上,全磷含量分布不均匀,土壤总体质量水平位于中下等水平,需要及时采取措施改善绿地土壤状况,从而提升城市人居环境和可持续发展水平。
In order to analyze the physical and chemical properties of the greenbelt in the residential area of Qihar City and provide a reference for the greenbelt management in the urban residential area, six representative greenbelt areas in the main urban area of Qiqihar were selected for sampling. Physical and chemical methods were used to determine the spatial distribution of Qiqihar Physical and Chemical Properties of Urban Residential Green Land. The results showed that the soil bulk density of greenbelt in residential area of Qiqihar was slightly larger, the compaction of soil was too tight, the soil contained more impurities, less water content, the porosity was within the normal range, the soil was too alkaline, and the content of organic matter was too low , The content of total nitrogen and total potassium is moderately upper, the content of total phosphorus is unevenly distributed, and the overall soil quality level is at the lower and middle levels. Therefore, measures should be taken to improve the soil condition in green space in time so as to enhance the urban living environment and the level of sustainable development.
