Evaluation of the Water Conservation Function of Different Forest Types in Northeastern China

摘要: Water conservation is an important function of forest ecosystems, but it still unclear which types best in this regard. We investigated the water indicators including water-holding rate branches and leaves (BLwr), capacity litter (Lwc), absorption (Lwr), soil infiltration (Ir), content (SWC), storage (SWS), organic matter (SOM) accumulation five (Larix gmelinii forests, Pinus koraiensis Robinia pseudoacacia tabulaeformis mixed forests) evaluated them using gray correlation method (GCM). The results indicate that BLwr stands study area varied from 18.3% to 33.5%. SWC SWS R. stand were 13.76% 178.9 mm, respectively, was significantly higher than other (p P. > pseudoacacia. Based on our results, had highest ability, while lowest performance found for tabuliformis site. This suggests that, order enhance forests northeastern China, focus should be establishment forests.
