月季花保鲜方法的研究

本研究以月季花为试材,品种为“小红帽”,比较了不同保鲜方法的月季花保鲜效果。结果表明:末端击碎法、浸烫法、茶水法以及啤酒法对月季鲜花均有不同程度的保鲜效果,其中以啤酒法保鲜效果最好,开花早,花期长,而且花朵艳丽,欣赏价值高,比对照延长了3 d;浸烫法延长了2 d;以末端击碎法处理的保鲜效果最差,比对照仅延长1 d;用茶水法处理过的鲜花一直未开花。

Extending rotation age for carbon sequestration: A cross-protocol comparison of North American forest offsets

Through carbon offset programs, forest owners can be offered financial incentives to enhance the uptake and storage of carbon on their lands. The amount of carbon that can be claimed by an individual landowner will ultimately depend on multiple factors, including the productivity of the forest, the management history of the stand, and the program in which the landowner is participating. This project presents a modeling framework for forest carbon accounting which is driven by forest yield curves and carbon pool partitioning. Within this model the amount of creditable carbon generated from adjusting the rotation age of multiple forest stands can be estimated for 46 distinct North American forest types. The model also provides a comparison of total creditable carbon generated under three carbon accounting methodologies: the Department of Energy 1605b Registry, the Chicago Climate Exchange, and the Voluntary Carbon Standard. In our evaluation of a 5-year rotation extension across 102 unique modeling scenarios, we find large differences among the carbon accounting schemes. This has implications for both forest landowners and policymakers alike. In particular, methodologies to account for such issues as leakage, permanence, additionality, and baseline establishment, while potentially increasing the overall legitimacy of any forest carbon offset program, can reduce creditable carbon to the forest owner (by up to 70%). Regardless of the protocol used, we also note strong regional differences, with Pacific Northwest forests of fir, spruce, hemlock, alder and maple being the most effective at sequestering carbon on a per area basis.     

从旅游业发展趋势谈我国旅游管理体制改革

林农与市场对接的两种博弈模型

文中把在农村林业经济中具有规模经营效应的组织形式划分为以龙头企业为主导模式和以合作组织为主导模式,分析了以龙头企业为主导模式的优势;通过建立企业与林农的博弈模型,指出以龙头企业为主导模式的缺陷,而以合作组织为主导模式不仅具有以龙头企业为主导模式的优势,还能够避免其缺陷。     

毛竹花期不同器官内源激素含量的变化

用酶联免疫法测定未开花毛竹和开花毛竹叶、花、枝、秆和鞭中内源激素吲哚乙酸(IAA)、赤霉素(GA3)、脱落酸(ABA)和玉米素核苷(ZR)的含量,分析开花毛竹内源激素分布和含量的变化与花形态分化的关系.结果表明:与未开花毛竹相比,成花期(6月中旬)开花毛竹叶、枝和秆中的IAA含量显著降低,枝的ABA含量也显著降低,而秆的ZR含量显著升高;扬花期(7月中旬)开花毛竹枝中的IAA含量显著降低,而GA3含量则显著升高.内源激素在开花毛竹各器官中的分布规律:IAA为秆＞鞭＞枝＞花,GA3为花＞鞭＞枝＞秆,ZR为花＞枝＞秆＞鞭,ABA为秆＞枝＞花＞鞭.二级枝中IAA含量显著低于一级枝,而其GA3和ZR的含量高于一级枝.IAA、GA3和ABA在竹杆中的含量呈向基性增加,而ZR则呈向基性减少.在成花期和扬花期ABA、ZR和GA3所占比例高于未开花毛竹,高比例的ABA、ZR和GA3和低比例的IAA可能促进毛竹花的发育.

Emerging Markets for Ecosystem Services

Abstract

Four main areas of learning were pursued during this exploration of die emerging markets for ecosystem services. First, die markets in Panama are dominated by the Panama Canal Authority and by timber revenues. Any strategy for expanding ecosystem services markets will have to reflect diese realities. Second, while the scientific and business components of die framework we used to analyze diese markets covered all the key points, more work needs to be done on die policy component. Articulating a simple, yet effective approach for developing policy recommendations to improve ecosystem services markets in context remains a key need. Third, valuable lessons were learned about ensuring tiiat the students capture die maximum benefits from an international, clinically-based field trip. Finally, interdisciplinary teaching/ research benefits dramatically from botii a focus on a single problem and recognition that the key challenge is turning complex scientific knowledge into accessible, good advice.
