| 7 | 绿色跨越与战略领先显示文摘千禧十年即将结束,人类届住的世界依然面临着自然环境与社会的众多挑战。随着挑战的规模和范围不断扩大,提高生态资源的利用效率、提升污染的防治力度和加强对工业产品的改良等逐步改进的策略已难以成事。一些商业公司转而直接面对环境与社会问题,探寻解决问题的有效途径。 | Stuart L.Hart | 2009 | 商学院2009,,2: | 0 |
| 8 | “在地进程”开拓陌生市场显示文摘我们在上期专栏中介绍了发展中国家将成为跨国公司最大的潜在市场,在这些国家建立的新项目必须充分考虑是否具备可持续发展的特质。这次我们可以系统分析一下如何使这些可持续发展的项目做到充分本土化,我把它称为推动一次“在地进程”(in—field processes) | Stuart L.Hart | 2009 | 商学院2009,,4: | 0 |
| 9 | 跨国公司如何在中国农村市场有所作为?显示文摘很多跨国公司的业务在已建立的市场上停滞不前,服务于金字塔底层的机会正变得越来越有吸引力。跨国公司的全球战略和新兴市场战略之所以会遇到瓶颈,因为即使他们在发展中国家投资,仍然是面向广大人口中的富人,但为大多数人提供的服务却不甚成功,而且并不是以可持续发展作为基本的模式。 | Stuart L.Hart | 2009 | 商学院2009,,3: | 0 |
| 10 | Three-dimensional light structure of an upland Quercus stand post-tornado disturbance显示文摘Light is the most common limiting factor in forest plant communities,influencing species composition,stand structure,and stand productivity in closed canopy stands.Stand vertical light structure is relatively simple under a closed canopy because most light is captured by overstory trees.However,wind disturbance events create canopy openings from local to landscape scales that increase understory light intensity and vertical light structural complexity.We studied the effects of an EF-1 tornado on horizontal and vertical(i.e.three-dimensional)light structure within a Quercus stand to determine how light structure changed with increasing disturbance severity.We used a two-tiered method to collect photosynthetic photon flux density at 4.67 m and 1.37 m above the forest floor to construct three-dimensional light structure across a canopy disturbance severity gradient to see if light intensity varied with increasing tornado damage.Results indicate that increased canopy disturbance closer to the tornado track increased light penetration and light structure heterogeneity at lower forest strata.Increased light intensity correlated with increased sapling density that was more randomly distributed across the plot and had shifted light capture higher in the stand structure.Light penetration through the overstory was most strongly correlated with decreased stem density in the two most important tree species(based on relative dominance and relative density)in the stand,Quercus alba L.(r=-0.31)and Ostrya virginiana(Mill.)K.Koch(r=-0.27,p<.01),and indicated that understory light penetration was most affected by these two species.As managers are increasingly interested in patterning silvicultural entries on natural disturbances,they must understand residual stand and light structures that occur after natural disturbance events.By providing spatial light data that quantifies light structure post-disturbance,managers can use these results to improve planning required for long-term management.The study also provides comparisons with anthropogenic disturbances to the midstory that may offer useful comparisons to natural analogs for future silvicultural consideration. | Kevin G.Willson Lauren E.Cox Justin L.Hart Daniel C.Dey | 2020 | Journal of Forestry Research2020,31,1: | 0 |
| 11 | Disturbance history,species diversity,and structural complexity of a temperate deciduous forest显示文摘Stand structural complexity enhancement is an increasingly popular management objective,especially on public lands.Complex stand structures are hypothesized to support a relatively high degree of native forest diversity and be more resistant and resilient to disturbances.Complex structures are characterized by the presence of deadwood and heterogeneity of tree-size classes and tree architecture.Relatively little is known about how discrete disturbance events affect structural complexity and compositional diversity in Quercus-dominated stands at fine spatial scales(i.e.neighborhoods).We established 200.05 ha fixed-radius plots on the Sipsey Wilderness of William B.Bankhead National Forest in northern Alabama to quantify woody plant species composition and structure.Trees were mapped on each plot to quantify overstory structural complexity and compositional diversity.We extracted two cores from all canopy Quercus spp.C 5 cm diameter at breast height to quantify age,recruitment pulses,and reconstruct canopy disturbance history.Shannon species diversity in the sampled area was 1.75 for trees,2.08 for saplings,and 1.69 for seedlings.Quercus alba had the greatest basal area,and Ostrya virginiana had the highest density.The stand exhibited a reverse J-shaped distribution with a q-factor of 1.72.The oldest Quercus dated to 1795,and the largest recruitment pulse occurred in the 1870s.The mean return interval for intermediateseverity disturbance was 38 years.Although we documented no relationships between disturbance frequency and compositional diversity at the neighborhood scale(0.05 ha),less frequent disturbance was associated with higher structural complexity(r^2=0.258,p=0.026)at the neighborhood scale.We suggest that localized disturbance increases species diversity and structural complexity,but these processes are manifest at the stand level and not at the neighborhood scale.We conclude that the spatial variability(i.e.size,shape,orientation,microsite conditions)is likely more influential on diversity and complexity than the temporal variation(frequency)of these processes at the neighborhood scale. | Jonathan D.Goode Carson R.Barefoot Justin L.Hart Daniel C.Dey | 2020 | Journal of Forestry Research2020,31,2: | 0 |
