摘要：The continuous cropping of flue-cured tobacco in the major producing areas of Henan Province by designing questionnaire, fieldwork, enquiry and phone calls, mails, and other forms, the data were obtained then classified and analyzed. The results showed that the main planting areas of flue-cured tobacco were in Nanyang, Xuchang, Luoyang, Sanmenxia, Pingdingshan, and Luohe where were the major producing areas of succession cropping of flue-cured tobacco with percentage of 20%-40% for three years and over three years, and a few places up to 50%. Morbidity was common with wide distribution, and the main diseases were black shank, viral disease, and black rot. It proved that tobacco was not suitable for continuous cropping. Both of tobacco disease and pest rate and mortality significantly increased by more than 40% under continuous cropping for three years and over three years, and the yield and quality of flue-cured tobacco also decreased after continuous cropping. For many places, the tobacco yield started to decrease in the second year of continuous cropping, and after three-year cropping, the yield decreased in the range of 9%-24%. Continuous cropping for a long time would make a serious decline in the quality of tobacco, resulting in non-economic benefits. Therefore, in order to reduce the occurrence of diseases and economic loss in tobacco production, it is recommended to avoid continuous cropping, or to adopt appropriate measures to control tobacco continuous cropping obstacles in the unavoidable case.

摘要：为分析山区梯田撂荒的影响因素,科学指导山区梯田的建设,该研究以位于山区的林州市、沂水县、寻甸县、华池县为研究区,在每个县选取若干采样区,以遥感解译结合实地调研的方式识别出山区撂荒梯田,并从山区梯田工程设计的角度对其撂荒的影响因素进行分析。研究结果表明:1)4个研究区内梯田均呈现出不同程度的撂荒现象,其中华池县、寻甸县、林州市和沂水县的采样区平均撂荒率分别为4.11%、7.68%、24.03%、9.46%;2)梯田的田面宽度是影响山区梯田撂荒的主要因素;3)在以沂水县和林州市为代表的石质山区,地面坡度与土层厚度是制约梯田宽度的主要因素,梯田的宽度随着地面坡度增加而变窄,随着土层厚度的变薄而变窄;在以华池县和寻甸县为代表的土质山区,地面坡度是梯田宽度的主要限制因素。该研究可为山区梯田的优化提出科学理论指导,并为国家相关部门制定政策提供理论依据。

摘要：指出了设计是为大众服务的,使其能够满足大众的需求,但同时社会中有着大量的弱势人群,学生也是弱势群体的一类,为使学生能够更好地在校园生活,应为学生的情感体验、学习体验以及社交体验提供好的校园环境,校园环境的使用主体是师生,通过充满情感与人性化的设计方法,能够让人更舒心的居住与生活,情感设计将感性理念和关怀设计带入人们的视线,面对新的挑战,设计师们不仅要不断完善自己的功能和形式,更要让人们在实际中感受到情感和关怀。阐述了目前高校的景观现状及存在的问题,并提出了高校校园的情感设计,以供参考。

摘要：该文根据朝代更迭,行政范围的变动,以及现存资料,参考包括民居在内的大范围建筑史的分期史料,把江西的民居史分为七个时期,并对其各个时期的演变革新及时代特征做简要的叙述,以便纵向观察江西民居,更好地理解江西民居遗存现状。

摘要：旗袍起源于满族袍服,是具有中华民族鲜明特色的女性服饰,是中华服饰文化中璀璨夺目的瑰宝,在世界服饰文化舞台上独领风骚。旗袍体现了东方女性之美,其审美意识的变迁也反映了中华民族审美文化在顺应时代潮流中不断地发展变化。文章以不同时代对旗袍审美的变化为脉络,结合社会发展与文化变迁,探究民族审美意识的变化与旗袍发展的紧密关联性。

摘要：实测了研究区8个自然极限状态坡建立地质模型。从地质勘探报告中收集了592组土样的土工试验数据，分地层年代统计了其物理力学指标。选取临县-离石公路沿线9个工点的实验数据，统计了该区c、φ值的变异系数，并对其变异性进行了分析。将c、φ值变异系数进行组合，进行了Monte-Carlo模拟。模拟结果显示，所测8个极限状态坡稳定系数为0.96～1.14，不同变异系数组合下，失效概率多为33.0％～61.8％。进一步对坡高为50.5m和81.8m的自然极限状态坡进行分析，分析结果显示：对于坡高为50.5m的边坡，在变异系数取当地平均水平（COVc＝0.66，COVφ＝0.28）时，若设计要求失效概率不超过10％，则坡率不应高于1！1.81；对于坡高为81.8m的边坡，在该变异系数组合下，若设计要求失效概率不超过10％，则坡率不应高于1！1.94。

摘要：利用射流清淤在疏浚工程中已得到广泛的应用并发挥了重要的作用,探究工作射流条件和沙床边界条件对冲蚀效果的影响有助于疏浚设备的优化设计及提高疏浚效率。观测和分析了静止平面斜向射流在不同射流速度、射流角度及沙床坡度条件下冲蚀沙床的过程、冲坑形态、以及冲坑外浑水流动特征。结果表明:二维冲坑剖面存在几何相似性,几何形态不对称,整体向下游发展;冲坑发展过程可分为初始、发展和稳定三个阶段,冲坑的深度随时间的变化呈对数关系增长,在冲坑深度达到最大深度一半时冲蚀速率最大;二维冲坑面积随射流角度的增大呈先减小、后增大的关系变化,在45°时存在极小值;泥沙冲蚀量、坑外浑水流运动速度随着沙床坡度的增大而增加,而坡度大于10‰后冲蚀量增长趋势趋缓。
