Soil protection for a sustainable future: options for a soil monitoring network for Ireland

The increased recognition of the importance of soil is reflected in the UN Post‐2015 Development Agenda with sustainable development goals that directly and indirectly relate to soil quality and protection. Despite a lack of legally binding legislation for soil protection, the European Commission remains committed to the objective of soil protection. However, the achievement of a legally binding framework for soil protection relies on the implementation of a soil monitoring network (SMN) that can detect changes to soil quality over time. As beneficiaries do not pay for the provision of soil information, the options for soil monitoring are limited. The use of existing data sets should be considered first. Using Ireland as an example, this research explored the opportunities for a SMN for Ireland considering three existing national data sets. The options for a SMN are considered in terms of their spatial and stratified distribution, the parameters to be measured and an economic analysis of the options proposed. This research finds that for Ireland, either a 10 or a 16 km² grid interval stratified by land use and drainage class offers the best potential in relation to the spatial distribution of existing data sets to reflect local data at a national level. With existing data, the stratified SIS data using the 16 km² grid offers the best value for money, with baseline costs for analysis, excluding field costs, of between €706 481 and €2.8 million. Acknowledging the impossibility of measuring all parameters with ideal frequency, this study proposes a two‐tier system for optimized monitoring frequency. Parameters must anticipate future policy requirements. Finally, the implementation of a SMN must be accompanied by standardized methods, defined thresholds and action mandates to maintain soil quality within allowable limits.     

社会林业与五指山的自然保护

五指山自然保护区是世界上现存地势最高的原始热带雨林之一，是我省目前面积最大的自然保护区，也是海南三大河流的发源地。但由于保护区横跨琼中、通什、保亭三县、市，紧邻保护区还生存着众多贫困的黎、苗族村民。因此，保护区与周边社区的联系是十分紧密的，社区的发展也直接影响到五指山热带天然林的保护。海南省林业局中德海南热带林保护和恢复项目在社会林业与五指山森林的保护上做出了有益的尝试，就在全省来说，也是首次对社会林业与森林保护上进行的探索。五指山地区社会林业的研究，对保护海南热带雨林也有着积极的意义。特对社会林业与五指山的森林保护进行了阐述、分析和设想。     

The Brief Introduction to the Sino-US Joint Centers for Soil and Water Conservation and Environmental Protection

Erosion and transport of soil has worldwide implications for agriculture, landscape stability, climate, natural hazards, and clean, renewable resources of water and air. Assured access to clean water and a healthy and safe environment requires an ethic of conservation and protection. The minimum scale in which these principles apply successfully is basin wide. These are the fundamental concerns of the Sino-US Centers for Soil and Water Conservation and Environmental Protection.     

Passive protection of mice with antiserum to neuraminidase fromPasteurella multocida serotype A:3

Antiserum to a partially purified neuraminidase fromPasteurella multocida, type A:3, was adsorbed with protease-digestedP. multocida type 3 lipopolysaccharide (LPS) to remove LPS immunoreactivity. The LPS-adsorbed antineuraminidase caused a 77% reduction in the neuraminidase activity of homologousP. multocida in anin vitro enzyme neutralization test. All 14 mice passively immunized with the adsorbed antineuraminidase were protected against challenge infection with homologousP. multocida in a mouse protection test. Ten out of 14 mice in one group that received antisera containing antibodies to both neuraminidase and LPS were protected. In contrast, only 1 out of 14 mice that were immunized with pre-immune serum survived the challenge. These results suggest that antiserum toP. multocida neuraminidase was, at least partly, responsible for the protection observed in this study. Neuraminidase may be one of the immunogenic protective proteins present in aqueous extracts ofPasteurella multocida.     

木质材料的表面劣化与木材保护的研究

本试验以枫桦(Betula costata Trautv)、紫椴(Tilia amurensis Rupr)木材单板和凸版纸、新闻纸、条纹牛皮纸、书写纸、胶版纸和朴克原纸为试材,借助于电子自旋共振波谱仪和扫描电子显微镜观测和分析了经室内、外暴露和人造紫外光辐射期间各种木质材料表面化学和表面性状的变化;提出了抑制木材表面劣化,保护木材的处理方法。研究结果表明,采用电子自旋共振波谱仪和扫描电子显微镜可以监测木质材料的劣化过程。采用化学药剂处理和油漆涂饰处理均可抑制紫外光对木材表面的光化降解,其中用浓度为5％的三氧化铬溶液或三氯化铁溶液处理木材其保护作用显著,能够改善木材的耐候性能。
