摘要

对甘肃祁连山4种不同林地类型的土壤特性、凋落物持水量、林地土壤蓄水性能、土壤渗透性能等进行了研究。结果表明

林地内土壤容重和孔隙度(0—60cm)差异较大

容重大小依次为:牧坡草地>祁连圆柏林>高山灌丛林>青海云杉林;总孔隙度大小依次为:青海云杉林>高山灌丛林>祁连圆柏林>牧坡草地。林地间凋落物的最大持水量和最大持水率表现一致

趋势表现为:高山灌丛林>青海云杉林>祁连圆柏林>牧坡草地。不同林地间土壤非毛管孔隙持水量差别较大

4种林地的土壤非毛管孔隙持水量由大到小依次为:青海云杉林>高山灌丛林>祁连圆柏林>牧坡草地。有效涵蓄量大小与土壤涵蓄降水量一致

4种林地变化范围为184.98～222.27mm

大小顺序依次为:青海云杉林>牧坡草地>高山灌丛林>祁连圆柏林。
