- Abstract:
- Taking Pinus massoniana plantations with different ages in Mengguan Forest Farm of Huaxi District of Guiyang City as the research objects, the forest gap (control), young forest, middle forest, mature forest and over-mature forest were selected to examine the litter reserves and water holding capacity by field investigation and laboratory analysis. The results showed that there were significant differences (p < 0.05) in the litter reserves and water holding capacities at the different ages, the regular patterns of the litter reserves and water holding capacities first increased and then decreased, litter reserves and water holding capacities were the largest in mature forest and the smallest in the young forest. the litter reserves, the maximum water holding capacity, the maximum water holding capacity and the modified interception of mature forest were 35.29 t/hm2, 84.48 t/hm2, 239.49% and 38.31 t/hm2, respectively; they were 10.19 t/hm2, 12.33 t/hm2, 120.38% and 6.71 t/hm2 in the young forest; water absorption rate increased fastest within the initial 0.25 h, indicating that the litter could play the role in water interception in a short period of time. This study shows that the mature forest has the best eco-hydrological characteristics.
