- 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.
