| 英文简介 | Zhonggou small watershed in semi-arid hilly and gully area of Longdong Loess Plateau will be acted as the research area. Taking the interaction mechanism between forest and water, selecting Robinia pseudoacacia forest with different site conditions and stand structure as research subjects, based on the site conditions and ecohydrological process at slope scale, the soil moisture, surface runoff and soil erosion will be surveyed by field observation. The sap flow of individual Robinia pseudoacacia in standard plot will be measured by the heat pulse technique, taking DBH and sapwood area as the conversion factors to get stand transpiration consumption, connecting with the survey of crown conception and forestland evaportranpiration to obtain forest actual evapotranspiration.Changing rule of soil erosion and ecological water are planned to research to verify the relationship between water erosion, ecological water consumption and stand structure, look for optimal stand structure with the lowest ecological water consumption cost and the best soil erosion benefit, improve and perfect the theoretical basis and technological level for the construction of soil and water conservation forest with multiple function. |
