转基因农业生物技术安全隐忧及其监管研究

随着转基因农业生物技术的迅猛发展,由其带来的潜在风险也日益被世人所关注。文章指出转基因农业生物技术在转基因农产品的食用安全性、转基因农作物的环境安全性、目的基因的遗传与表达稳定性等方面存在潜在风险,并在总结转基因农业生物技术安全监管的国际经验的基础上,提出我国应在防止不同农作物之间的基因漂移、完善转基因农产品的标识制度、加大转基因技术的研究力度等方面加强转基因农业生物技术的安全监管。     

龙爪槐育苗嫁接修剪技术

龙爪槐主干婷婷直立,上部树冠伞形,枝条蟠蜒扭曲,姿态别致,宛如腾跃的龙身和搏击风雨的龙爪。龙爪槐培育方法很多,采用好的方法不仅可以提高苗圃地利用率,同时可以增加出苗率,使出苗整齐茁壮,便于各项管理,特别有利于同一时期嫁接及嫁接后的管理。现就实际工作中对龙爪槐从育苗嫁接及栽植后的修剪技术经验作一总结。     

丹麦农业生产中的肥料使用及其对中国的启示

现代农业中大量使用的化肥在提高作物产量的同时,也带来了一些负面影响如土壤肥力下降、土壤板结等。文章综述了丹麦先进的肥料使用和管理方面的经验。丹麦政府通过根据作物需要制定N的允许施用量和P、K的推荐施用量、对肥料的施用季节和施肥方式进行规定、根据土壤检测的结果和作物产量调整营养元素施用量等措施较好地避免了化肥污染问题。这些先进的经验为中国解决化肥污染问题提供了借鉴。笔者提出中国在农业生产过程中应从限制化肥使用量、提高农民知识水平、提倡增施有机肥、改进施肥方式等方面避免对环境的污染。     

安吉县竹业发展经验与启示

浙江省安吉县为我国十大"竹乡"之一。安吉竹业总产值居全国产竹县之首。究其原因是多方面的,既有自然条件的优越,又有悠久的借竹为生的历史传统,尤其是还有当代全县人民的艰苦创业。安吉选择了一条以竹业为支柱、生态经济高效持续发展的道路,其成功经验具有普遍意义,值得有关地区借鉴和推广。     

林业外资投资的贸易效应及对策研究

林业外资投资及我国林产品市场的特点, 决定了目前我国林业外资投资的创造效应相对替代效应来说表现得更为明显, 相应地促进了林产品贸易和出口的快速增长, 而对进口的影响则较弱。不过, 现阶段林业外资投资的增加对林产品出口贸易结构改善的影响并不大, 因此有必要采取措施改变这种状况。     

采摘果园经营管理策略研究——以尤溪县洋中镇老友生态农场为例

果园采摘是休闲农业的一个重要类型，在减少农产品流通环节、开拓农产品销售渠道、创建品牌、发展三产融合、提升农业经济效益方面具有明显的优势。笔者以尤溪县洋中镇老友生态农场为例，分析了采摘园存在缺乏规划、服务理念不到位、采摘品种单一、同质化竞争激烈、劳动力成本高、精细化管理不足、品牌建设滞后、营销推广不足等问题。提出对采摘园进行准确定位、采用高标准的绿色种植技术、配套完善服务设施、实现功能分区、利用新媒体进行营销推广、树立品牌等经营管理措施，以带动传统果园转型升级，实现乡村产业振兴。     

后脱贫时代国内外农业科技发展经验及其对我国的启示

农业科技扶贫在部分地区被认为是农户摆脱贫困、实现区域经济发展的重要途径。针对精准扶贫战略实施过程中出现的农业科技扶贫制度不完善、农户知晓度及参与率低等突出问题。在借鉴国内外农业科技发展成功经验的基础上，提出相应的优化建议：完善相关制度设计，激发科技人员参与的积极性，鼓励各地区因地制宜实施差异化组织管理模式，加大农业科技扶贫宣传力度，进而提高农户知晓度和参与率。在后脱贫时代要切实发挥好农业科技扶贫的助贫脱贫效用，为脱贫质量的巩固和乡村振兴的实施奠定基础。     

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.
