“…The results indicated that deciduous trees and shrubs were more suitable for soil quality recovery than evergreen trees. Different than in some degraded ecological systems, such as the Loess Plateau (Ni et al 2004;Fu et al 2005;Chen et al 2010) and dry-warm river valley (Li et al 2005;Yan et al 2006;Xu et al 2009), soil stratification on the landslides was seriously damaged by the earthquake. As described in this study, a mass of gravel and rock debris was scattered on the landslides (table 1).…”

Abstract:In order to find suitable vegetation types for wider earthquake-triggered landslide rehabilitation in the eastern Longmenshan, we chose six vegetation types, which included three artificial restoration vegetation types (shrub Paeonia decomposita, deciduous tree Betula albo-sinensis, and evergreen tree Cryptomeria fortunei), two natural restoration vegetation types (middle and high coverage of grasses), and one residual vegetation. Soil quality, runoff, and soil loss were evaluated for the six vegetation types. We found that high coverage of grass prevented surface runoff and soil erosion more effectively than other vegetation types, and the deciduous tree and shrub were more suitable for soil quality recovery than the evergreen tree after the landslide. Among the three artificially planted vegetation types, the roots of the deciduous tree had stronger expansion ability than those of the shrub and evergreen tree. Our results indicated that high coverage of grass and deciduous trees could complement each other to achieve a good restoring effect, which would not only help reduce surface runoff and soil erosion but also facilitate the formation of fertile islands and enhance the stability of subsurface soils. Therefore, the two vegetation types could be used to form an effective vegetation restoration pattern for wider earthquake-triggered landslide rehabilitation in this region.Key words: earthquake-triggered landslide-fertile island-runoff-soil erosion-soil quality-vegetation type On May 12, 2008, a catastrophic earthquake with a magnitude of Mw 8 and a focal depth of 19 km (11 mi) occurred at the Wenchuan area of the Longmenshan fault in Sichuan Province, China. The earthquake caused a colossal fault rupture with a distance of approximately 270 km (168 mi) and triggered enormous landslides; it was the worst mountain disaster in the 20th and 21st centuries (Chigira et al. 2010). After the earthquake, investigations were conducted using Beijing No. 1 and IKONOS earth observation satellite images with ground resolution of 32 m (105 ft) and 1 m (3 ft), respectively (Di 2008). The total area of landslides induced by this earthquake was 2,260 km 2 (873 mi 2 ), which was far larger than that of recent earthquakes in mountainous areas, such as the Chi-Chi earthquake in 1999 that occurred in central Taiwan (Lin et al. 2006), the Mid-Niigata Prefecture earthquake in 2004 that occurred in northwest Japan (Chigira and Yagi 2005), and the Kashmir earthquake in 2005 that occurred in northern Pakistan (Sato et al. 2007).The earthquake-triggered landslides changed green vegetation into naked rock and bare soil. The absence of a thick soil layer discouraged the percolation of rainfall, facilitated flow over the slopes as runoff, and increased the possibility of severe soil erosion when intense prolonged rainfall occurred. A preliminary estimation of soil erosion in landslides resulting from the earthquake was about 55.86 × 10 8 t (61.58 × 10 8 tn) (Chen et al. 2009). In order to reduce soil erosion and protect the enviro...

“…Emblematic examples are the worldwide transfer of Pinus radiata (Yan et al 2006) and the south to north translocation of Picea abies (Skrøppa et al 2010). This adaptation was achieved in very few generations of trees, and it proceeds from plasticity and/or evolution.…”

Managing forests under climate change requires adaptation. The adaptive capacity of forest tree populations is huge but not limitless. Integrating evolutionary considerations into adaptive forestry practice will enhance the capacity of managed forests to respond to climate-driven changes. & Aims Focusing on natural regeneration systems, we propose a general framework that can be used in various and complex local situations by forest managers, in combination with their own expertise, to integrate evolutionary considerations into decision making for the emergence of an evolution-oriented forestry. & Methods We develop a simple process-based analytical grid, using few processes and parameters, to analyse the impact of forestry practice on the evolution and evolvability of tree populations. & Results We review qualitative and, whenever possible, quantitative expectations on the intensity of evolutionary drivers in forest trees. Then, we review the effects of actual and potential forestry practice on the evolutionary processes. We illustrate the complexity of interactions in two study cases: the evolutionary consequences for forest trees of biotic interactions and of highly heterogeneous environment. & Conclusion Evolution-oriented forestry may contribute adapting forests to climate change. It requires combining short-term and long-term objectives. We propose future lines of research and experimentation.

“…1 and 2). Vegetation damage along the upper Minjiang River has taken place for at least a thousand years (Yan et al, 2006), and serious soil erosion has occurred, degrading soil water and nutrient conditions . In an effort to reduce the extent and magnitude of soil erosion, this area has become the key region for ecological rebuilding under the National Eco-environmental Renovating Scheme of China (Li et al, 2006a).…”

Understanding of the relationships between vegetation and soil and topography would be very important for ecosystem restoration and management efforts in the dry valleys of Himalayan region but how to clarify the complicated relationships and figure out key factors for practical purpose is a challenge. The main objective of this research was to propose a four-staged procedure by combining several multivariate statistical techniques to detect the relationships between vegetation and soil and topography, and thereby identify the key factors for the degraded ecosystem restoration and management. Forty-three plots (5 m × 5 m) were selected for the field survey of the vegetation, soil and topography variables in the dry warm river valley of the upper Minjiang River, Sichuan Province, China. Cluster analysis (CA) demonstrated that high plant diversity, cover and height were associated with good soil quality and favorable topographic positions with lower solar incident radiation, runoff and soil erosion potential. Correlation analysis (simple correlation analysis and canonical correlation analysis) and multiple linear stepwise regression analysis affirmed that plant diversity was mainly correlated with soil water content, and soil water content was mainly determined by soil texture (clay content). Soil clay content alone could explain about 70% of the total variance. Identifying the favorable topographic position and the distribution pattern of soil texture and its controlling mechanisms is thus very important for restoration practices. In the process of ecosystem restoration, we should promote the co-evolution of vegetation and soil, and follow the natural succession sequence. Some relevant conservation polices are also needed to reduce human disturbance on ecosystem.
