摘要: 以北京地坛公园古侧柏为研究对象,采用环刀法和烘干法分析了北京地坛公园古侧柏土壤理化特性。结果表明:1)古侧柏土壤含水量为14.54%;2)土壤容重为1.59 g/cm3;3)土壤的总孔隙度、毛管孔隙度和非毛管孔隙度分别为26.86%,40.14%和13.28%; 4)土壤紧实度为0.51 kg/m2

关键词: 古侧柏, 土壤含水量, 容重, 孔隙度, 土壤紧实度

Abstract: The study regards ancient trees platycladus orientalis in Beijing Ditan Park as the research objects.By using cutting ring method and drying method,soil physical properties were analyzed.The results showed that:(1)average soil water content(SWC)was 14.5%;(2)the mean bulk density of soil samples was 1.59 g/cm3;(3)the average total porosity,mean capillary porosity and medial non-capillary porosity of soil samples were 26.9%,40.2%,13.3%,respectively;(4)mean soil compaction was 0.51 kg/m2.

Key words: platycladus orientalis, SWC, bulk density, soil porosities, soil compaction
