广西钦州市菠萝山不同朝向土壤理化性状比较分析

以钦州市钦南区菠萝山为研究对象，采用环刀取土烘干法及混合土样法对不同区域（东南、西南、西北）土壤的理化性状进行分析。结果表明：不同采样区域（东南、西南、西北）土壤含水量和物理性粘粒（＜0.01 mm）差异显著，东南朝向含水量及粘粒含量最高，其次是西南朝向，西北朝向最低；不同采样区域（东南、西南、西北）土壤容重、孔隙度及 pH 值差异不显著。通过该研究表明，山体的不同方向对土壤发育及水土保持有显著影响，人为干扰影响山体土壤良性发展。

Pineapple Hill in Qinzhou City Toward the Physicochemical Properties of Soil Analysis

Taking Qinnan District of pineapple mountain in Qinzhou city as the research object, using the ring knife for different regional soil drying method and the mixed soil sample method （southeast, southwest, northwest） analysis, physical and chemical characters of soil. The results showed that： different sampling region （southeast, southwest, northwest） of soil water content and soil clay（ 〈 0.01 mm） significant differences, toward the southeast water content and clay content is the highest, followed by the southwest toward the northwest, toward the minimum; different sampling region （southeast, southwest, northwest） of soil bulk density, porosity and pH have no significant difference. Through the different direction of the study on the development of mountain soil and water conservation has a significant impact, human disturbance affect the benign development of mountain soil.
