Ecotonal changes and altered tree spatial patterns in lower mixed-conifer forests, Grand Canyon National Park, Arizona, U.S.A.

This research analyzes patch development and determines tree spatial patterns along the lower mixed-conifer ecotone on the North Rim of Grand Canyon National Park in Arizona (U.S.A.). Patterns of patch development were interpreted from spatial analyses, based on tree age and size, and past records of disturbance and climate. Five plots in the ecotone between mixed conifer forests and monospecific stands of ponderosa pine (Pinus ponderosa) were studied for patterns of patch development. The methods used include: (1) size-structure analyses, to compare species patch development; (2) dendrochronological dating of tree establishment; (3) tree ring master chronology, to determine periods of suppressed growth, compared to a Palmer Drought Severity Index; and (4) spatial analyses by species composition, size and age, with univariate and bivariate analyses of spatial association and spatial autocorrelation. We found an increased density of shade-tolerant and fire-intolerant species namely clusters of pole-sized white fir, and fewer large ponderosa pine.

生态停车场结构改良研究

为有效解决生态停车场交付使用后一段时间就出现草皮空秃严重的问题,该研究系统地对生态停车场结构中的3类面层材料、5类结合层材料、5类基层材料作了对比。结果表明:当停车场结构的基础为素土夯实,基层采用150 mm厚三七灰土加100 mm厚C15素混凝土,结合层采用30 mm厚1∶3水泥砂浆时,面层采用200~300 mm厚自然石既能有效控制草皮空秃问题,停车场的结构稳定性也较好;当停车场结构的基础为素土夯实,第1基层采用150 mm厚三七灰土,第2基层材料改用200 mm厚级配砂石,结合层材料改用50mm厚1∶3泥砂混合时,面层材料采用60 mm厚嵌草砖或70 mm厚植草格的综合效果良好。     

当前高职教育考试管理工作的思考

高职教育是我国高等教育的重要组成部分，其考试管理工作的有效开展直接影响了高职教育的长期发展。然而，当今高职教育考试管理在考试前、考试过程中、考试后三个阶段都存在很大问题。针对以上问题，文章提出加强考试前的组织管理、加强考试过程中的监督管理、加强考试后试卷的分析总结三个建议来促进高职教育考试管理工作的完善和发展，促进高职教育的科学化发展。     

林业生态建设对山区减贫的影响研究——以湖南湘西土家族苗族自治州为例

从中国证券业市场结构的现实特征入手，研究市场结构这一中观因素对证券公司效率的作用。通过实证检验，发现相对市场势力假说在中国证券业成立的证据，但进一步分析表明，市场份额的扩张并没有带来显著的效率损失，这与典型的相对市场假说并不相同。

Structural,rheological and gelatinization properties of wheat starch granules separated from different noodle-making process

In this study, three typical wheat cultivars (ZM366, AK58, and ZM103) with high, medium, and low gluten strength, respectively, were selected as the raw material. The starch granules separated from different stages of the noodle-making process, including kneading, resting, sheeting, cutting, and drying, were used to explore the structure, dynamic rheology, and quality of the noodles. The D50 (median diameter) of the starch granules decreased during the noodle-making process, and the reduction was enhanced by an increase in the gluten strength of the flour. Between steps 4 and 5 of the noodle-making process, the solubility of ZM103 variety increased from 4.3% to 5.0% at 80 °C, while the peak viscosity decreased from 3626 to 3386 mPa s, which resulted in a decrease in the cooking loss of noodles. Similar trend was observed in the ZM366 and AK58 varieties. The gelatinization enthalpy was reduced, suggesting that the crystalline regions of the starch granules were destroyed during the kneading process. Between steps 4 and 5 of the noodle-making process, the elastic modulus of the starch granules significantly increased, while the temperature at which maximum elastic modulus was decreased, indicating an increase in the crystalline stability of starch during the drying process. Correlation analysis indicated that the changes occurred to the gelatinization property was primarily due to the change in the particle size.     

论明清以来壮族种植结构的变迁

壮族是典型的稻作民族。明清以来,其农作物的种植结构因受地形、气候等自然地理因素,以及农作物的引进、人口的迁移等人文地理因素的影响,壮族地区农作物种植结构具有显著的特征。主要是平原地区农作物种植的品种不断增加,但水稻种植一直占据绝对的主导地位,而玉米、麦等杂粮在种植结构中的比重,大致呈由平原、丘陵向山地不断提升的趋势。这种变化正是壮族适应边疆民族地区农业地理环境的结果。
