摘要:
为了探知不同密度油松林人工林的水源涵养功能高低，选取木兰围场8个密度油松林的枯落物与土壤进行研究，利用水源涵养指数来比较各林分的水源涵养功能的高低，结果表明：（1）枯落物重量与有效拦蓄量变化趋势是随着密度的增加而增大，而枯落物最大持水量处于自身重量的2～4倍，最大持水率在250.61%～310.66%。（2）随着密度的增加土壤的最大持水量、非毛管孔隙度与非毛管蓄水量都是先是增加后减小，而最大持水量在1 800株/hm2达到了最大值为2 868.0 t/hm2；毛管孔隙度、毛管蓄水量与总孔隙度都没有明显的规律可言。（3）随密度的增加油松的水源涵养指数是呈现增加趋势的，其中的最大值是最小值的1.35倍，当密度处于1 500株/hm2时，指数趋于稳定，在1 500～1 800株/hm2时水源涵养指数较高。
Abstract:
In order to ascertain the function of water conservation level of plantation of different densities of Pinus tabulaeformis, we selected 8 density of Pinus tabulaeformis forest litter and soil were studied by using the index of water conservation, water conservation function to compare the stand level Mulan Wei Chang. The results showed that: (1) changes in litter weight and effective retaining content trend increased along with the density increase, and the maximum water holding capacity of litter was between 2～4 times of its own weight, the maximum water holding rate ranged from 250.61% to 310.66%; (2) the maximum density increased with soil water holding capacity, non-capillary porosity and non-capillary water volume first increased and then decreased, and the maximum water holding capacity was found in 1 800 plants/hm2, the reached maximum value was 2 868 t/hm2; capillary porosity, capillary water storage capacity and total porosity had no obvious rules; (3) with the increase of the density of Pinus tabulaeformis, water conservation index increased, the maximum is 1.35 times of the minimum value, when the density was 1 500 plants/hm2, index tended to be stable, in strain 1 500～1 800 plants/hm2 between high water conservation index.
