A preliminary classification of fruit-based agroforestry in a highland area of northern Thailand

Tree fruit crops are an increasingly important component of highland cropping systems in northern Thailand. A survey was conducted in three highland hill tribe villages in an upland watershed in Mae Hong Son Province to examine and classify the fruit-based cropping activities used by villagers. Members of ten households in each village were interviewed to establish activities and crop histories for each plot of land held by the household. From the sample of 85 ‘gardens‘ (plots with ten or more fruit trees), a field-level classification structure was developed reflecting function of trees, use and nature of herbaceous intercrops, and pattern of components. Through the classification process, four groups and 11 subsystems of highland tree fruit-based agroforestry were identified. The single most abundant subsystem was ‘mixed home gardens‘. A strong commercial element was also obvious. The survey indicates a very diverse ‘customized’ use of the fruit cropping system. The classification has potential for use in more extensive surveys of the nature of fruit cropping activities in the highlands and as a tool for further analysis in the study area. This revised version was published online in June 2006 with corrections to the Cover Date.     

Movements and habitat utilization of nembwe,Serranochromis robustus (Günther, 1864), in the Upper Zambezi River

Fifteen adult nembwe Serranochromis robustus (Günther, 1864) were tagged with radio transmitters in the Zambezi River, Namibia, from 4–15 November 2000 to record behaviour and outline the implications for fisheries management. The fish were tracked on average every 3.7 days until 18 May 2001. They stayed within relatively small home ranges, with a 95% probability of localization within an average area of 184 563m₂. The fish utilized a mean river stretch of 1330 m (range = 24– 3787). Nembwe were recorded in a variety of habitats, and the individual variation in movements and habitat use was substantial. All the fish were recorded in the mainstream of the river, but 62% of the fish were recorded in one or more additional main habitat types. During rising and high water, 67% and 71% of the fish, respectively, were recorded in adjacent temporary flooded areas during some or all tracking surveys, but did not undertake long-distance migrations onto the floodplains. It is concluded that although staying within relatively small home ranges, nembwe appears as a species with a variable and flexible habitat utilization.     

昆虫分类学的回顾与展望

本文第一部分,回顾了昆虫分类学在国外发展的情况,从亚里斯多德、林奈、达尔文到最近二十年,不同学派分类理论的提出和新技术的应用。第二部分,回顾了中国古代在昆虫分类上的成就、近二百年来反动封建统治和帝国主义侵略对中国分类科学的发展的阻碍、新中国成立后昆虫分类工作者所作出的贡献直至十年浩劫的破坏和科学春天的到来。第三部分,从全国收藏昆虫标本数量、已知种数、文献、出版物、研究人员和经费等方面的对比,找出我国昆虫分类领域和先进国家的差距。第四部分作者提出如何发展中国昆虫分类学的重要措施。     

英、美、澳、中小麦品种温光效应与主茎叶数的关系

小麦主茎叶片数是小麦发育的重要指标 ,温光条件对主茎叶数有显著地影响。英、美、澳小麦品种具有比中国同类品种主茎叶片数较多和温光效应较大的特点 ,但温光对主茎叶数影响的作用类同。冬性品种以春化作用为主 ,而春性品种以日长作用为主导因素 ,英国冬麦有较明显的温光互作效应。通过温光条件可以有效地调节主茎叶数 ,从而实现营养生长向生殖生长过渡的调节     

家居企业数字化转型与产品数字化设计的发展趋势

企业数字化转型已成为企业适应数字经济、谋求生存发展的必然选择。企业数字化转型是基于数字化技术,重塑或创新企业的业务模式、制造模式和管理模式,以提高企业组织管理效能和业务运营效率,提升产品（或服务）质量和用户体验。家居企业的数字化转型,最主要的体现是家居产品的数字化设计与制造,其中数字化设计是通过数字化的手段来支持家居产品设计研发与生产制造全过程,进而快速满足用户的个性化需求。本文主要分析企业数字化转型、产品数字化设计与制造、定制家居产品数字化设计的内涵与发展趋势,以期为我国传统家具或定制家居企业的数字化转型或产品的数字化设计与制造提供指导。     

推进社会主义和谐文化建设的若干思考

党的“十八大”报告明确提出了“扎实推进社会主义文化强国建设”的战略决策,和谐文化作为中国特色社会主义文化的重要组成部分,基于构建和谐社会的实践需要应运而生,具有丰富的内涵和鲜明的特征,它既是构建和谐社会的重要内容,又是实现社会和谐的文化源泉。和谐文化重在建设,不仅要植根传统文化的深厚土壤,更要汲取外来文化的营养成分,不仅要有科学理论的指导,更要有具体实践的推动。

毒死蜱在菠菜家庭处理中的变化及其饮食摄入量的暴露评估

菠菜中毒死蜱残留是一个备受关注的问题,我国开始采用叶菜类毒死蜱残留限量为0.1 mg.kg-1的标准。本文研究了毒死蜱从田间菠菜到消费者餐桌的全程变化情况,以及水洗、漂烫和冷却等家庭操作对农药残留的影响;并结合我国饮食结构中的蔬菜消费量,对毒死蜱饮食摄入量进行了最坏情形的暴露估计。在良好农业操作和安全间隔期为7 d的情况下,毒死蜱在大棚菠菜的残留量为0.85 mg.kg-1,高于0.1 mg.kg-1的限量要求,但符合原来限量标准1 mg.kg-1的要求;食用喷药后7 d的菠菜,通过原料的摄入量仅为ADI值的56.7%,为ARfD值的5.7%,因此从暴露评估的角度仍认为是安全的。     

农村留守妇女生活满意度影响因素调查及对策

为了解留守妇女生活满意度的影响因素及探讨提升生活质量的对策,对河北省200多个村的388名留守妇女进行了问卷调查,从客观条件、对留守的认知、家庭状况和生产任务等方面分析了影响留守妇女生活满意度的因素.结果表明:留守妇女的文化程度均偏低,其中,文化程度高的生活满意度相应较高;留守妇女中照顾老人的负担非常沉重,大部分(76％)妇女至少需要照顾2位老人,其对生活的满意度较低;住房宽敞和够住的妇女的满意度显著高于住房拥挤的妇女;家庭月收入高于1 000元的妇女满意度显著高于低收入的妇女;交通状况满意度最高的是水泥路与柏油路;对休闲健身设施的要求不高;联合家庭中的留守妇女的满意度显著高于核心家庭;自愿留守、经常与丈夫联系、很少与丈夫吵架、与公婆关系很好的留守妇女的生活满意度显著较高.并针对研究结果提出了提高留守妇女生活满意度的对策和建议.
