“…Also, global collectors under the canopy of each of ten sample trees were installed to collect the throughfall in each plant community in the years of 2006 and 2007. The canopy interception was calculated by rainfall minus throughfall (Tang et al 2007).…”

“…Moreover, the species diversity and plant coverage in the understory of the Eucalyptus plantation is low in central Yunnan (Tang et al 2007), and it cannot weaken the impact of waterdrops with high kinetic energy on splashing the soil, resulting in further soil erosion and nutrient loss exporting from the ecosystem. Natural and mixed forests have higher biodiversity and contain more life forms than the single-species plantation, and the high number of branches in multi-species crowns also enhance water storage, especially in heavy rains where it can reduce impact of rainfall on surface soil Zhang et al 2003;Park and Cameron 2008).…”

“…The single-species plantations could concentrate the amount of nutrient in the biomass and had greater nutrient uptake by the plant, resulting in depletion of nutrient resources in the soil of the subtropical central Himalayas (Lodhiyal and Lodhiyal 1997). The poor nutrient availability of the soil in the single-species plantations has a negative effect on plant species distribution and prevented understory growth, leading to a decrease in biodiversity and further soil erosion (Tang et al 2007). In these plantations, the lower biodiversity, higher soil erosion, and lower soil moisture and fertility subsequently affected the microclimate, which may bring about a reduced rate of litter decomposition because of retarded activity of soil microorganisms Sims 1999, 2001;Barlow et al 2007).…”

Nutrient relocation, hydrological functions, and soil chemistry in plantations as compared to natural forests in central Yunnan, China Abstract The relocation of nutrients among dominant plant species, along with hydrological functions and soil chemistry in five plant communities, including Eucalyptus plantation, Pinus plantation, shrubland, semi-natural, and natural secondary forests were investigated in central Yunnan, China. The nutrient P, N, and K accumulation in above-ground biomass of Eucalyptus smithii (stems, barks, branches, and leaves) were the highest, followed by Pinus yunnanensis of both the Pinus plantation and the semi-natural forest. The nutrient retranslocation efficiency (NRE) of E. smithii was the highest for nutrient P, N, and K with values of 56, 66, and 67%, respectively, among the dominant plant species of the five plant communities, while the NRE of P. yunnanensis in Pinus plantation had the second highest value of NRE for nutrient N. The nutrient content (available P, N, and soil organic matter) in the upper two soil layers under Eucalyptus and Pinus plantations was correspondingly found to be lower than that of the other forests. Moreover, under the Eucalyptus and Pinus plantations, surface runoff, soil erosion, and nutrient loss were more serious, and the water storage of litterfall and canopy interception were significantly lower than that in the other plant communities. Accordingly, we suggest that single-species plantations cannot present the same ecological benefits as natural forests, because of their simple, uniform structures, and the characteristics of the dominant plant species.

“…The primary climax vegetation of the study area is an evergreen broad-leaved forest (EBLF), dominated by three wooden species Cyclobalanopsis glaucoides, Castanopsis orthacantha, Castanopsis delavayi (Xiwen and Walker, 1986;Tang and Ohsawa, 2009;Tang et al, 2007). Previously introduced land cover maps show that EBLF has been replaced by coniferous forests in many parts of the study area, and only accounts for 16% of the total area (see Section 2.2).…”

Debris‐flow fan development and geomorphic effects in alpine canyons under a changing climate

Debris flows in alpine environments are prone to occur in the context of global climate change (i.e., elevated air temperature and higher frequency of strong precipitation events). (Alluvial) Fans often develop at the outlet of tributaries after high‐intensity debris flows. Most debris‐flow fans in alpine canyon areas extend directly to the main river channel and become the forefront of the interaction between the tributary gully and the main river channel. Clarifying the development processes/dynamics, evolutionary mechanisms and driving factors of alluvial fans would shed light on understanding the geomorphological effects and genesis of river valleys in alpine canyon areas. Here, we report the development of debris‐flow fan at the outlet of the Tianmo Gully, a formerly hazard‐free but currently hazard‐active tributary of the Parlung Tsangpo Basin, Southeast Tibet, where debris flows have occurred frequently in the last two decades. Combining remote‐sensing images, DEM data, UAV aerial photography, RTK topographic survey and other fieldwork, the development processes and morphological characteristics of the Tianmo fan under the influence of four large debris flows were analysed. Both primary events (described as episodic debris‐flow events characterized by high‐magnitude mass movement) and secondary events (corresponding to perennial stream flow processes with much lower sediment concentrations) affected the development of the Tianmo fan. Episodic debris‐flow events drastically shape the macroscopic morphology of the fan, with rapid deposition and expansion of the fan body, whereas perennial stream flow processes slowly modulate the fan during the intermittent period between debris flows, mainly with gradual retrogressive incision and lateral migration of flow channel on the fan body. Influenced by the strong sediment‐transport process of debris flows and the alluvial fan development, the planform of the Parlung Tsangpo River evolved from a relatively narrow and single‐thread pattern to an alternating‐wide‐and‐narrow pattern, with a corresponding staircase‐like longitudinal profile.
