- Abstract:
- Based on the data from fixed sample plots of main forest types in Jinyun Mountain in Chongqing City, water conservation capacity were studied. The results showed that there is a binary linear regression for both through fall and stem flow to precipitation quantity and precipitation intensity. The relative interception ranges from 16.91% to 67.84% on an average of 38.19%. Under the same rainfall the decrease order of canopy interception in the different forest types is coniferous and broad-leaved mixed forest, broadleaf forest, bamboo forest. The biomass of litter layer in different forest ecosystems varies from 16.21 to 32.42 t/hm2 on an average of 20.69 t/hm2 and the decrease order of the biomass is shrubbery, broadleaf forest, coniferous and broad-leaved mixed forest, bamboo forest. The total interception of rainfall in different forest ecosystems varies from 450.3 to 686.3 t/hm2 the decrease order is coniferous and broad-leaved mixed forest, broadleaf forest, bamboo forest, shrubbery.
