摘要:
为探究苏北马陵山区的立地质量，以该区域东海县西山林场不同造林模式的人工幼林为对象，通过样方调查和室内分析相结合的方法，采集土壤 0—30 cm 土样进行理化性质及其相关性的分析。结果表明：（1）土壤沙砾含量高，pH呈中性，平均容重为1.41 g/cm3，总孔隙度为30.53%，土壤较紧实，通气性差；（2）不同土层的土壤养分含量均存在显著差异（P＜0.05），且随土层深度增加，养分含量逐渐下降；（3）土壤有机质、全氮、全钾、有效磷、速效钾的养分均属于贫乏和极贫乏级别，仅全磷属于适量及较丰富。认为该区土壤紧实，养分含量除全磷外均处于极低水平，其土壤物理性质在一定程度上可表征其土壤的部分化学性质。以上结果可为苏北马陵山区的林业工程建设与管理提供重要的数据参考。
Abstract:
In order to explore the site quality of Maling Mountain area in Northern Jiangsu, with the woodlands of different afforestation modes in Xishan Forest Farm as the object, through the method of sample survey and laboratory analysis, soil samples of in depth ranged within 30 cm were collected for physico-chemical properties and correlation analysis. The results showed that in Xishan Forest Farm, (1) The soil was enriched with gravel, the pH was neutral, the average bulk density was 1.41 g/cm3, the total porosity was 30.53%, the soil was compact and the ventilation was poor; (2) There were significant differences in soil nutrient content between different soil layers(P<0.05), and the nutrient content gradually decreased with the increase of soil depth. (3) The nutrient levels of soil organic matter, total nitrogen, total potassium, available phosphorus and available potassium were poor and even extremely poor, and only total phosphorus was moderate and even abundant. In summary, in this comapct soil, nutrient content except total phosphorus in Maling Mountain area were at an extremely low level, and soil physical properties even characterize part of the chemical properties in the study area to a certain extent.
