采用土壤调查的方法，对福建省武夷山市5种主要茶园土壤类型（黄壤、红壤、潮砂土、高山草甸土、紫色土）的土壤主要物理性状进行了研究。结果表明：不同土壤类型之间的土壤物理性状存在着明显差异，高山草甸土属于砂质粘壤土，土壤田间持水量、土壤含水率、土壤总孔隙度和土壤毛管孔隙度最大，土壤容重、土壤固相和气相最低，土壤物理性状最好；黄壤和红壤属于粉粘土，土壤物理性状次之；潮砂土和紫色土属于砂壤土，田间持水量、土壤含水率和毛管孔隙度显著低于其它土壤类型，土壤物理性状最差。相关分析表明，田间持水量、土壤含水率、土壤固相、土壤容重、土壤孔隙度、土壤毛管孔隙度之间均存在显著或极显著相关性（P<0.05，P<0.01）；土壤砂砾、粉粒和粘粒之间均存在极显著相关性，其中土壤砂砾、粉粒均与田间持水量、土壤含水率、土壤气相、毛管孔隙度、非毛管孔隙度之间呈显著或极显著相关性（P<0.05，P<0.01），土壤粘粒仅与毛管孔隙度和非毛管孔隙度之间存在显著相关性（P<0.05），与其它指标相关性不明显（P>0.05）。

Based on the field survey analysis, this paper studied the soil physical properties in five soil types (yellow soil, red earth, moisture sandy soil, alpine meadow soil and purple soil) of tea garden in Wuyishan City. The results showed that the soil physical properties in different soil types were significant difference. The soil physical properties of alpine meadow soil were the best. The field capacity, soil moisture, soil porosity and capillary porosity of alpine meadow soil were the largest, whereas the bulk density, soil solid and gas were the lowest. The alpine meadow soil was made up of sandy clay loam. The yellow soil and red earth were silty clay. The moisture sandy soil and purple soil were silty loam, and their field capacity, soil moisture and capillary porosity were significantly lower than other soil types. There were significant or extremely significant correlation among field capacity, soil moisture, bulk density, soil porosity and capillary porosity(P<0.05,P<0.01). There were significant correlations among sand, silt and clay. The sand and silt were significantly or most significantly correlated with field capacity, soil moisture, soil gas, capillary porosity and non-capillary porosity. The soil clay had only significant correlation with capillary porosity and non-capillary porosity (P<0.05), but had no significant correlation with other soil physical properties(P>0.05).
