摘要:
以北京松山5个不同密度（784，1 024，1 210，1 616，1 872株/hm2）的丁香（Syzygium aromaticum）天然林为对象，对其枯落物层及土壤层水文效应进行研究。结果表明：枯落物总蓄积量、最大持水率、最大持水量随丁香天然林密度的升高而增大。枯落物的总储量在13.19～31.66 t/hm2之间；有效拦蓄能力在32.71～79.77 t/hm2之间；枯落物最大持水量在50.76～119.29 t/hm2之间，与浸泡时间呈明显的对数关系（R > 0.86）；枯落物最大持水率为385.72%～507.16%，枯落物吸水速率与浸泡时间呈明显的幂函数关系（R > 0.99）；同一密度土壤容重随土层深度的增加而增大，总孔隙度随密度的升高先增大后减小。初渗速率在37.50～54.55 mm/min之间，入渗速率与入渗时间存在较好的幂函数关系（R > 0.99）。中密度丁香天然林水源涵养功能较强。
Abstract:
A preliminary study on hydrological effects of litter layer and soil layer in natural Syzygium aromaticum forests was carried out in the five different densities (784, 1 024, 1 210, 1 616, 1 872 per/hm2)in Songshan mountain of Beijing. The results showed that the total storage capacity, the maximum water holding rate of litter and the maximum water holding capacity increased with the increase of density; the total storage capacity of litter was about 13.19~31.66 t/hm2, the modified interception capacity of litter was about 32.71~79.77 t/hm2; the maximum water holding capacity of litter was about 50.76~119.29 t/hm2 and had significant logarithmic correlation with immersion time(R > 0.86); the maximum water holding rate of litter was about 385.72%~507.16% and had power function relationship with immersion time(R > 0.99); the soil bulk density increased with the increase of depth of soil layer in the same density. The total soil porosity increased firstly and then decreased with the density. The initial infiltration rates of soil varied between 37.50 mm/min and 54.55 mm/min. The infiltration rate had power function correlation with infiltration fit time(R > 0.99). Syzygium aromaticum forest with medium density had stronger water conservation function.
