上海临港新片区中心城区海洋文化产业体验经济型发展的ASEB栅格分析

海洋文化产业,作为海洋产业发展的新引擎,对推动海洋产业升级、延长海洋产业链具有重要作用。在体验经济学的背景下,通过调研上海临港新片区,在获得相应资料的基础上研究其海洋文化产业的发展状况,并运用ASEB栅格对其如何体验式开发进行系统性梳理与分析。研究发现:临港固有相对丰富的海洋文化、渔业旅游资源和区位优势,但存在体验性不足、品牌形象不强、开发方式单一问题,这制约了该区域的发展。为此,提出如下建议:(1)突出海洋文化产业的体验性;(2)塑造海洋文化产业的体验形象;(3)优化海洋文化体验品牌,提升知名度与影响力;(4)打造以滴水湖为依托的系列体验业,推动形成海洋文化产业集聚效应;(5)加强当地高校对海洋文化产业的支撑。这将有助于新片区中心城区未来海洋文化产业的合理开发,以期能够为新兴沿海城市发展相关产业提供参考与借鉴。

一起经营添加目录以外物质饲料产品案的查处体会

2017年9月,甘肃省凉州区农牧局在日常检查时,查处一公司经营的饲料产品涉嫌非法添加其他物质。经立案调查,认定该公司经营的四黄止痢颗粒、抗病毒消炎颗粒、参芪增免颗粒、感冒神奇颗粒中擅自添加国务院农业行政主管部门公布的饲料添加剂品种目录和药物性饲料添加剂品种目录以外物质的违法事实确实,根据《饲料和饲料添加剂管理条例》规定,依法给予了行政处罚。本文通过对案件定性、查处过程及行业规范监管策略进行讨论,提出了多视角案件定性、先行追溯核查生产企业、陈述申辩与申请听证的不同处理和规范企业生产行为的监管举措。为切实规范兽药饲料经营秩序,强化饲料及饲料添加剂生产企业监管提供参考。     

古巴非洲猪瘟根除的经验与借鉴

1971年非洲猪瘟首次传入古巴并于当年根除,1980年再次传入并在一年内又被根除。古巴能快速根除非洲猪瘟,主要与防控专业委员会的及时成立,协作机制的快速建立;全面扑杀措施的快速实施,健康猪产品的合理利用;民间团队的积极参与以及政府财政的大力支持密切相关。古巴的根除经验,可为我国非洲猪瘟的防控提供参考。

Enhanced pest control in cabbage crops near forest in The Netherlands

Landscapes are composed of a multitude of habitat types which, potentially, can influence natural enemy populations. The contribution of specific habitat types to sustaining natural enemy populations in agricultural landscapes and the associated ecosystem service of pest control is not well understood. We investigated how landscape composition affected parasitism rates in 22 organic Brussels sprout fields in The Netherlands. Second and third instar larvae of Plutella xylostella were placed on experimental Brussels sprout plants in Brussels sprout fields and were recovered after two days in the field. Parasitism rates ranged between 4 and 94% and were related to landscape variables at a scale of 0.3, 1, 2 and 10 km. Univariate analysis using a generalized linear mixed model indicated that parasitism rates were positively related with area of forests at a scale of 1, 2 and 10 km, forest edges at a scale of 1 and 2 km and road verges at a scale of 1 km. Forest and road verges are likely to provide food and alternative hosts for parasitoids and are less disturbed habitats than agricultural fields. These results suggest that forests and road verges may play an important role in sustaining effective densities of parasitoids of P. xylostella in agricultural landscapes.     

Evaluation of the effect of eprinomectin in young dairy heifers sub-clinically infected with gastrointestinal nematodes on grazing behaviour and diet selection

Inappetence is commonly associated with parasitism and has been observed in both housed and pastured ruminants. In seeking a functional explanation for these observations, it has been hypothesised that parasitized animals may feed more selectively in order to proportionally increase the protein content of their diet and thus partially compensate for their reduced feed intake. Support for this theory is found principally in studies in housed animals under carefully controlled experimental conditions. Grazing animals face a far more heterogeneous environment and a multiplicity of potentially confounding factors that could influence diet selection. Controlled grazing of adjacent monocultures of grass and clover can mitigate some of these variables and was used in the current study to examine the dietary preference of dairy heifers with sub-clinical parasitic gastroenteritis when compared to those receiving regular anthelmintic treatments. Grazing behaviour and herbage intake rates were determined through the use of jaw-movement recorders, direct observation and short-term liveweight change. Consistent with previous observations and despite evidence that nematode burdens were low in the untreated control heifers, a reduction in daily grazing time of 56 min (P = 0.054) was observed in the control animals. There was, however, no evidence that the control heifers showed greater preference for clover compared with ryegrass: partial preference for clover was 73.0% in the untreated controls and 75.5% in the treated heifers. Furthermore control heifers were observed grazing the clover swards significantly (P = 0.032) less frequently than the treated heifers. This study provides additional evidence in grazing cattle for parasite-induced inappetence, manifest as a reduction in grazing time and in subtle changes in ingestive behaviour. The observed partial preference for clover in both treated and control cattle was not significantly affected by the level of parasitism.

Biodiversity and environmental stressors along urban walking routes

There is increasing focus on designing liveable cities that promote walking. However, urban walking routes can expose people to adverse environmental conditions that reduce health, well-being and biodiversity. Our primary objective is to assess how urban form is associated with environmental quality, including biodiversity, for people moving through urban spaces. We assess a range of environmental conditions that influence human health and biodiversity (temperature, noise and particulate pollution) and biodiversity of three taxa (trees, butterflies and birds) along 700 m public walking routes embedded in 500 m x 500 m grid cells across three UK towns. Cells are selected using random stratification across an urbanisation intensity gradient. Walking routes in more built-up areas were noisier and hotter; noise levels further increased in areas with more industrial land-use and large roads. There was no evidence of vegetation mitigating noise or temperature, but there was some evidence that increased vegetation cover mitigated small particulate pollution. Walking routes in more built-up environments had lower butterfly, bird and native tree species richness, and reduced butterfly abundance. Large roads were associated with reduced bird species richness and increased noise was associated with reduced bird abundance. Most specific measures of vegetation in the surrounding matrix (median patch size, structural complexity at 1.5 m resolution) were not detectably associated with biodiversity along walking routes, indicating minimal beneficial spill-over. Increased garden cover in the surrounding matrix was associated with less abundant and less species-rich butterfly communities. Our results highlight considerable heterogeneity in the environmental quality of urban walking routes and pedestrians’ potential to experience biodiversity along these routes, driven by reduced quality in areas with more built cover. A greater focus is needed on mitigating adverse effects of specific features of the built environment (roads, industrial areas, noise) surrounding walking routes to enhance the co-benefits of more biodiversity and healthier conditions for pedestrians.
