Poisson’s ratios of an oriented strand board

In the assessment of the structural adequacy of oriented strand board (OSB) members by design calculation, the need for the boards Poissons ratios often becomes evident. However, mention of Poissons ratios as a relevant mechanical property is seldom made in wood-based panel test and design standards. The short-term principal Poissons ratios of a typical OSB has been determined from tension tests. Mean values of 0.23 and 0.16 have been obtained for the major and minor Poissons ratios, respectively. The experimentally determined Poissons ratios appear consistent with the values estimated from the panel shear and tension moduli of elasticity. Complementary values of the Poissons ratios in bending have been estimated from the bending moduli of elasticity and tension test results for the panel. Efficiency in the assessment of OSB by design calculation follows from knowledge of Poissons ratios. However, for this benefit to be realised in routine design, the Poissons ratios of structural grade OSB need to be available.     

Discussion on Status and Functions of China’s Forestry

In recent years, the quantity and quality of global forest resources are declining continually. Contrarily, the both in China are increasing, which is deeply related to the sustainable forest management and eco-system management in China. With the trend that world community knows more about the important role of forest, more and more functions of forest are recognized. The impact and functions of China’s forestry deserve more concern. Based on some experiences in the field of forestry research, the authors introduced and analyzed the key role of China’s forestry for the sustainable development, and explained the functions of China’s forestry, such as ensuring ecological safety, addressing climate change, improving economic development, promoting social harmony and prospering ecological culture.     

It’s what’s inside that counts: computer-aided tomography for evaluating the rate and extent of wood consumption by shipworms

Experiments were done to investigate in situ colonization of pine wood blocks by marine wood borers at the mouth of a small mountain river in the foothills of the Eastern Pyrenees. Standardized blocks were recovered after remaining underwater for increasingly long durations, until the available resource was exhausted by the shipworms assemblage that developed. Computer-aided tomography (CT) was used for visualizing and quantifying biogenic structures into the wooden blocks. The biodiversity survey of the wood pieces colonized indicated that up to three species of shipworms shared the resource at the same time. The specific wood consumption rate of Nototeredo norvagica was estimated 185 mm³ ind^?1 day^?1. The quantification of voids created by shipworm crowding indicated that total tunnelling represents, on average, 60% of the initial volume of a wood block, revising upward earlier estimates of wood destruction by 28%. CT analysis provides the quantitative measurements necessary to parameterize individual-based growth models linking wood consumption with the species diversity of shipworm assemblages.     

Regional differences of water conservation in Beijing’s forest ecosystem

The water conservation capacities of main forests in Beijing,China were estimated through the quantitative analysis.Various methods developed in published papers on forest hydrology were employed.The forests in Huairou,Yanqing,Miyun,Mentougou and Fangshan districts are the main contributors to water conservation(the cumulative ratio reaches 65%),and the forests in Tongzhou,Chaoyang,Shunyi and Daxing districts have the highest water conservation capacity(3000 m3/ha).Altitude and slope are the key factors to affect the water conservation capacity.The forests located in Plain Area,Hilly Area,Low Mountain,and Middle Mountain contributes 27%,28%,24% and 21% of the conserved water,respectively.The water conservation capacity of forests in Plain Area(2 948 m3/ha),is superior to the forests in other regions.And the forests situated on Flat Slope,Moderate Slope and Gentle Slope constitute the largest proportion(nearly 93%) of water conservation,while the forests on Flat Slope has the highest water conservation capacity(2 797 m3/ha),and the forest on Steep slope has the lowest water conservation capacity(948 m3/ha).     

China’s Forests and Their Impact on Global Carbon Cycle

Forests have multiple benefits and functions, including mitigation of climate change. The impacts of forests on the global carbon cycle include forests as carbon sinks, wood-based products as carbon sinks, bio-energy, and production and use of non-timber products. In the past decades, forest cover of China has increased from 8.6% to 18.21% by large-scale afforestation and conversion of cropland into forests. Forest biomass carbon (C) stock increased from 4.3 Pg C (1 Pg C = 1 015 g C) in the early 1980s to 5...     

Forecast of China’s Forestation Area Based on ARIMA Model

Man-made forest, which is the forest ecosystem of rehabilitation and reconstruction, plays a significant role in the provision of forest products and improvement the ecological environment. In this paper, we established the AR (5) model to predict China's forest area from 2009 to 2015. This study shows the slow growth of the national plantation area trend with some fluctuations, but the overall growth rate is not large. We proposed that on one hand China should continue to increase the plantation area, on t...     

Ideas on Policy Framework of China’s Bamboo Industry Development

1 FUNCTION AND INSTRUMENT OF INDUSTRY POLICY In a market economy, the relationship of supply and demand and the price lever adjust the direction and the scale of investment, and competition mechanism determines the survival of enterprises. Therefore, the industrial scale, structure and pattern can be achieved through the market mechanism. However, due to market failure, market dysfunction and other reasons, it cannot often achieve the optimal allocation of resources solely relyin…     

Emission Removal Capability of India’s Forest and Tree Cover

India is the world’s tenth most forested nation with 76.87 M ha of forest and tree cover occupying 23.4% of its geographical area. Forests—with their intrinsic of carbon sequestration and storage values—are in the front line of India’s climate change mitigation strategies. This paper provides estimates of sequestered carbon in India’s forest and tree cover for the years 1995 and 2005 as per the IPCC good practice guidelines method. It is based on the primary data for the soil carbon pool through collecting soil samples by laying out quadrats across the country and secondary data for the growing stock of all forest and tree cover in the country. The estimates are compared with current and future projected emissions. It is found that conservation policies have resulted in increase of the country’s forest carbon stocks from 6244.8 to 6621.6 Mt with an annual increment of 37.7 Mt of the carbon from 1995 to 2005. Annual CO₂ removal by the forests is enough to neutralise 9.3% of the country’s 2000 level emissions. Continued removals by the forest and tree cover would offset 6.5 and 4.9% of India’s projected annual emissions in 2010 and 2020 respectively. Economically, the annual value of this forest carbon in the international market is about US $188 million. The result is of use in the REDD and REDD+ context for India.     

Institution, Legislation and Policy Analysis of China’s Wetland Protection

Wetland protection is a complex issue. In the executive system of wetland preservation, the central government is the main body of policy formulation and implementation. Although China has taken many steps to protect wetlands, there are still some institutional, legal and policy problems in the area of wetland protection. This article presents an analysis of these factors. First, the authors state and analyze the major legal and management problems currently hampering wetland protection in China. Then the authors believe that in the future, new problems of wetland protection will arise. Given the following three major aspects of wetland protection in China: i.e., the policy, law and management systems, this article provides some relevant suggestions in the area of policies and management.     

Development Trend of Foreign Trade Policy for China’s Forest Industry

Trends and responses to global change of China’s arid regions

I analyzed and elaborated the trends in and responses to global change in arid regions of China, from the perspective of nine variables, i.e., temperature, precipitation, river runoff, melting glaciers, water level of lakes, wind power and evaporation, vegetation, oases, and desertification. The climate and hydrology data I cited represent many years of observations. I conclude that, since the 1980s, the climate in arid regions of China has clearly changed with rising temperatures and precipitation in most areas. Wind power and the number of galestorm days have continuously decreased, which resulted in an improvement of humid conditions and increases in river discharge and water levels of lakes. Simultaneously, vegetation also has improved and the process of desertification has essentially been arrested. Although there are some unfavorable developments, such as decreased river flows or flow interruptions and downstream oases have suffered from degradation, these incidental cases should not distract our attention from the generally favorable trends during the middle and late 20th century. These discordant phenomena are not consequences of climate change but rather of unsuitable human activities. Despite a substantial increase in precipitation, the level of the original precipitation was so small that any increase in precipitation was still small. As a result, none of the fundamental conditions such as a scarcity of water resources and precipitation nor the landscape of drought-ridden deserts in the arid regions will change. The vulnerability of the eco-environmental system in the arid regions will not change fundamentally either in the near future. __________ Translated from Scientia Silvae Sinicae, 2008, 44(8): 124–130 [译自: 林业科学]
