- Abstract:
- Determine the proper stand density of soil and water conservation forest in Loess area should obey on the rule of "afforestation amount based on precipitation".According to water balance principle, under fully use precipitation and without runoff and soil deeply percolation, the amount of water consumption of stand during growing season should be smaller or equal to precipitation amount.Basis on that principle, the value of proper stand density of Robinia pseudoacacia and Pinus tabulaeformis was calculated in Caijiachuan watershed.Based on the observation data of soil water dynamic changes of 13-old Robinia pseudoacacia with different stand density and 17-old Pinus tabulaeformis with different stand density during growing season in 2002 and 2003, the value of stand density with best anti-arid abilities of Robinia pseudoacacia and Pinus tabulaeformis forest was the same as the calculated value of stand density according to the formula.This result show that this formula has good application on calculation the proper stand density in Loess area.Besides, the parameters of this formula are easy to get.Therefore, this method to calculate proper stand density in Loess area should be popularized further more.
