饲料经营环节监管中存在问题及解决措施

随着我国经济不断发展,社会不断进步,人民群众生活水平不断提升,促使养殖业也在大环境下逐步快速壮大起来。近年来,由于人们对畜产品的需求量增多,畜产品质量和安全问题也就备受社会各界关注。尤其是饲料及饲料添加剂作为投入品在养殖环节的使用中明显增加,饲料也是影响动物性食品安全的一个重要因素。因此,畜牧兽医部门在监管中发挥着至关重要的作用,如何做好监管的问题值得深思,笔者就如何做好饲料经营环节的监管工作予以探讨,提高工作效率。     

Stress recovery and restorative effects of viewing different urban park scenes in Shanghai,China

ObjectivesMany studies have found that natural environments benefit human health and wellbeing, but few have measured restorativeness of specific landscape components, especially in Chinese settings. Because the rapid urbanization of China is accompanied by increasing predomination of hardscape components in cities, the restorative quality of urban green space is a crucial issue. This study explored the stress recovery effects of different videotaped scenes, using six urban parks and one urban roadway scene. Potentially restorative urban park scenes were controlled for nature-based vs. hardscape components, presence/absence of people, and level of openness.MethodsSubjects were Chinese university students (N = 140) aged 18–24. After completing an oral exam as a stressor, an equal number of males and females were randomly assigned to watch one of the seven videotaped scenes during a stress recovery stage, while data were collected on changes in stress and attentional levels. Physiological responses were measured by Electrocardiography (ECG) and Skin Conductance Response (SCR). Psychological responses were measured by the state (short-term) version of the State-Trait Anxiety Inventory (STAI-S), the Digit Span Backwards (DSB) test, and the Perceived Restorativeness Scale (PRS).ResultsIn a Chinese sample, this study confirmed previous findings that nature-based urban park scenes relieved stress and restored attentional levels, while viewing an urban roadway increased negative feelings. Overall perceived restorativeness was significantly higher in two scenes depicting a Lawn without people and a Small Lake, compared with a paved Plaza with or without people, confirming previous findings that restorativeness is associated with predominance of nature-based landscape components. This study also confirmed previous findings that outdoor scenes without people were more restorative than scenes depicting people.DiscussionThis study found different levels of restorativeness associated with different landscape features, and helped confirm that nature-based components are more likely to reduce stress than hardscape components, using Chinese urban scenes with a Chinese population. Findings can be used in future planning and design of urban spaces in China, emphasizing the value of parks and green spaces in relevant contexts.

内蒙古自治区外来入侵植物的问题与对策

随着全球经济一体化进程的不断深入,生物入侵严重威胁生态环境、公众健康及区域经济发展.本文在多年实践基础上,对国内外文献进行收集、汇总和对比分析,以明确内蒙古自治区外来植物入侵现状、发生的特点和趋势,以及对畜牧业生产和生态安全的影响等,并提出相应的防治对策,以期为内蒙古自治区外来植物入侵的防控提供理论依据.结果表明,目前,内蒙古自治区外来入侵植物已达45种,其中分属16个科36个属.入侵植物以一、二年生草本为主,占总入侵植物的79.5％,入侵来源以国内其他省区传入和国外直接传入两种途径实现;入侵植物有19种原产自美洲,占入侵植物总数的42.2％,欧洲次之,为18种.虽然内蒙古自治区外来植物入侵防控取得了一定成效,但是整体上存在重视程度不足、相关法制法规不健全、监管脱节、投入不足,评估与预警机制不健全、相关研究滞后等问题.因此,应加大资金投入,提高防范意识,建立入侵植物风险评估、早期预警监测体系,提升科研能力和监测技术水平,构建信息平台,加强对外交流,从而保障内蒙古自治区的生态安全,确保人民生命和财产安全,维护社会和谐稳定发展.
