- Abstract:
- Larix principis-rupprechtii plantation of Mulan Forestry Management Bureau was selected as study case. Water holding capacities of litter in Larix principis-rupprechtii plantations with different ages and different densities were studed based on quartering method. The results showed that the optimal stand densities were 2 500, 1 800, 1 000, 800 plants/hm2 for 20, 30, 40, 50 years of Larix principis-rupprechtii plantations, respectively, maximum and effective water-holding capacity reached to maximum for litter. With the density increase, maximum and effective water holding capacity increased and then decreased. A similar relationship with stand density variation and tree growth law of water holding capacity of litter, preparation of water holding capacity density control diagram of Larix principis-rupprechtii plantation litter, can offer essential data reference and basis for the water conservation forest density management of Larix principis-rupprechtii in North Mountain of Hebei.
