- Abstract:
- Transformation of Cunninghamia lanceolata plantation was an important measure to improve forest stand quality and its ecological functions. In this paper, transformation methods of Cunninghamia lanceolata plantation in Foshan, were taken as the example to study the water-holding capacities of soil and litter with different forest ages. The bulk density, porosity and water holding capacity of soil for experimental forest with different age segments were not significant (P < 0.05), while those parameters of soil rose with the extension of forest ages, and water conservation of soil was improved. Litter biomass and water-holding capacity of litter increased with the increase of forest ages. Biomass and water-holding capacity of litter in experimental forest with the ages of 9～11 years were significantly higher than those of litter in experimental forest with 3～5 years (P < 0.05), while water-holding capacity of litter was not significant with 3～5 years experimental forest. The litter soaking experiments showed that the water holding capacity increased with soaking time, following a logarithmic curve, while water absorption rate decreased with soaking time, following inverse function relationship. The maximum water-holding capacity of litter layer was much less than the soil layer, which accounted for 0.18%, 0.11% and 0.08% of the maximum water-holding capacities of soil. Forest soils become the subject of water conservation. The improvement methods of Cunninghamia lanceolata, Mytilaria laosensis, Cinnamomum burmannii, Elaeocarpus sylvestris, Liquidambar formosa and Cunninghamia lanceolata, Michelia macclurei, Mytilaria laosensis, Cinnamomum burmannii, Schima wallichii and Cunninghamia lanceolata, Schima superba, Elaeocarpus sylvestris, Toona sinensis, Trema orientalis showed good water holding capacity of soil and litter by analyzing water holding capacity of soil and litter.This study results can provide scientific basis for planting tree selection, near natural transformation of stand, forest management and assessment of service function of forest ecosystem.
