【摘要】 本文对哈尔滨城市绿地土壤的人为干扰类型特点进行了研究。根据绿地土壤的土地利用类型，将哈尔滨城市绿地划分为公园与广场绿地、公共庭院与居住区绿地、道路交通绿地、生产绿地4个区域13个采样区。对其土壤的理化性质和养分状况等指标进行分析，并与松花江地区自然黑土进行了对比，研究其变化的趋势和养分相关性。结果表明：哈尔滨城市绿地土壤容重较大，孔隙度和田间持水量少，有机质缺乏，养分含量较低，相关性差，土壤pH值呈中性，肥力水平低。 通过综合分析，找出了哈尔滨城市绿地土壤的障碍因素，提出了改良方向与措施，对北方城市的绿化具有一定的参考意义。更多还原

【Abstract】 This paper deals with the characteristics of human -disturbed soils in Harbin city . Samples were collected from thirteen areas covering different types ofvegetation ,which was divided into four parts:park and square,public courtyard and living area,road and traffic area,nursery area. The physical and chemical properties of the soil were analyzed ,including nutrient change and routine index of acidity and alkalinity,in addition,compared them with natural soil and studied their variation and correlation .The results as follows:The soil bulk density of Harbin urban vegetation is higher,total porosity and field capacity are small. Organic materials are scant. Nutrient is very limited and the correlativity is not clear. The soil is neutral. Fertility is also lower. Aiming at solving these serious problems,we put forward improvement ways and methods,which will have profound significance in afforesting and beautifying northern cities.更多还原
