摘要
为了研究舟山本岛及离岛土壤的理化性质,本文以舟山本岛及离岛的工、农、生活区域的土壤为研究对象,以土壤容重、孔隙度、pH值、有机碳含量、石油类物质含量、含盐量、含水量、氯离子含量及养分元素(有效K、Ca、Mg、Cu、Fe、Zn、Mn)含量为测定指标。研究结果表明,舟山本岛及离岛试验点0~30 cm土层土壤均呈弱酸性;容重和孔隙度均在适宜范围内,土壤的透气性较好,且土壤中含水量丰富,达到适宜甚至偏湿水平;土壤中氯离子含量为38.1~171.6 mg/kg,高于全国平均水平(59.6 mg/kg),且土壤中的氯离子含量和含盐量随土层变化的趋势具有一致性,属于中轻度盐化土壤;土壤肥力较好,有机碳含量普遍达到了一级水平;土壤中有效Mn、Fe、Zn的含量处于中高水平,有效Cu含量处于中下水平,而有效Mg、Ca、K的含量处于较低水平;土壤中石油类物质含量为34.94~296.44 mg/kg,均在安全范围内,土壤并没有受到石油污染。
In order to study the physical and chemical properties of soil on Zhoushan island and outlying islands,this paper taked the soil in the industrial,agricultural and living areas of Zhoushan island and outlying islands as the research object,and takes the soil bulk density,porosity,pH value,organic carbon content,petroleum material content,salt content,water content,chloride ion content and nutrient element (effective K,Ca,Mg,Cu,Fe,Zn,Mn)content as the measurement index.The result showed that the soil layer of 0~30 cm in Zhoushan island and outlying islands was weakly acidic. Both bulk density and porosity werewithin the appropriate range. The air permeability of the soil was better,and the water content in the soil was rich,reaching the appropriate or even wet level.The content of chloride ion in soil was 38.1~ 171.6 mg/kg,higher than the national average (59.6 mg/kg),the content and salinity of chloride ion in soil are consistent with the trend of soil layer change,which belonged to moderately and mildly saline soil. The soil fertility was good and the organic carbon content reached the first level generally. The effective contents of Mn,Fe and Zn in the soil were at medium and high levels,the effective contents of Cu were at medium and low levels,and the effective contents of Mg,Ca and K were at low levels. The content of petroleum in the soil was 34.94~296.44 mg/kg,all within the safe range,and the soil was not contaminated by petroleum.
