网络安全的隐患及管理

随着经济的发展,社会的进步,计算机技术得到了快速的发展,第三次科技革命促进全 国进入了计算机网络时代。我国接触计算机技术时间较短,但是也紧追时代的潮流,得到了快 速的发展,进入计算机时代得到的不仅仅只是机遇,越来越多的计算机网络安全问题涌现出来, 严重影响了我国计算机网络的安全稳定发展。本文主要就目前阶段计算机网络存在的问题展 开探究,找出造成网络安全的主要问题,并提出解决的措施。     

基于Geomatics的南京东郊野生动物景观安全格局分析-以露牙獐为例

以南京东郊中型哺乳动物露牙獐为研究对象,采用2007—2009年47个物种痕迹点和江苏基础地理信息数据库的8个环境变量为主要信息源,在空间信息技术Geomatics支持下,采用最大熵法（Maxent）生态位模型,建立潜在生境预测模型。通过ArcGIS空间分析模块,构建露牙獐景观安全格局。结果表明：在快速交通网络的囚笼效应作用下,保护对象露牙獐的潜在生境呈高度破碎化空间分布格局;在影响露牙獐潜在生境的生态环境因子中,距公路距离（41.9%）、距铁路距离（178%）、距居民点距离（14.7%）3个因子的贡献率占74.4%;在研究区域,露牙獐有3个呈大陆-岛屿复合种群关系的栖息地,4条栖息地的源间联接通道,3个位于山间谷地和鞍部的战略点。     

鲜活农产品在连云港市的物流与营销

指出了人们对农产品的消费观念发生了深刻的变化,从消费者对农产品的需求及消费者购买行为两方面分析了连云港市的市场环境,并对鲜活农产品在连云港市的物流与营销进行了探讨。     

基于生态足迹的青海省生态安全初步研究

在生态足迹原理的基础上,将生态压力指数作为生态安全评价的指标,同时制定了相应的指标等级划分标准,对青海省1985—2003年的生态足迹和生态承载力进行了测算,并利用生态压力指数及其等级划分标准对其生态安全进行了试评价。评价结果显示,青海省近11 a来的自然生态处于较安全状态,但生态压力指数呈上升趋势。     

种粮利益与粮食安全利益的一致性试析

规模经营以前,粮农属于收入最低的群体,努力种粮也不能保障自己的粮食安全和经济安全。离开粮食 生产行业,可以提高粮农的粮食安全和经济安全水平。而国家的粮食安全与粮农的粮食安全和经济安全利益会出现 不一致现象。解决不一致现象,需要培育新型农业经营主体,实现规模经营,降低成本,使种粮收入大幅度提高,使粮 农成为体面的职业,让农业成为有奔头的产业。这样,国家的粮食安全与粮农的粮食安全和经济安全利益才能相一 致。同时探索耕地产权自有的制度改革,强化耕地作为财产的价值和功用,增强耕地吸引力,激励更有竞争力的劳动 者保障国家粮食安全。     

Achieving food and nutritional security through agroforestry: a case of <Emphasis Type="Italic">Faidherbia albida</Emphasis> in sub-Saharan Africa

Faidherbia albida is an ideal agroforestry tree commonly intercropped with annual crops like millet and groundnuts in the dry and densely populated areas of Africa. With its peculiar reverse phenology, it makes growth demands at a different time from that of crops. In addition, it deposits great amount of organic fertilizer on food crops. Leaves entering soils are comparable to fertilization of almost 50 t·ha 1 ·year 1 of manure in dense stands of 50 large trees per ha. These nutrients help maximize agricultural production and reduce the need for a fallow period on poorer soils. Research has shown that millet grown under F. albida yielded 2.5 and 3.4 fold increases in grain and protein, respectively. Animals eat pods which contain mean amounts of crude protein of 20.63% and carbohydrate of 40.1% in seeds. Moreover, the continued existence of F. albida in agroforestry parklands as in Ethiopia and Mali signifies the success of traditional conservation measures. Modern scientists have also developed much interest in the role of agroforestry in maintaining long-term biological balance between agriculture and livestock production systems. To ensure food security, which still remains a major challenge in sub-Saharan Africa, and concurrently minimize environmental degradation, promotion of agroforestry that specifically involves indigenous trees is crucial. We discuss the prospective role of F. albida in alleviating poverty while simultaneously protecting the environment from factors associated with, for example, deforestation and loss of biodiversity. The overall aim is to promote wide-scale adoption of F. albida as a valuable tree crop in farming systems, particularly in those areas where it remains unexploited.     

土地利用规划对土地生态安全的影响评价——以江苏省沛县为例

以江苏省沛县土地利用规划的现状数据及规划数据为依据,构建合理的评价指标体系,应用层次分析法确定指标权重,采用综合指数多目标决策模型对沛县的土地生态安全进行测算评价。研究结果表明,沛县的土地生态安全指数2005年为0.549 3,2010年为1.541 4,2020年为2.036 2,指数值明显增加,说明通过对沛县进行新一轮土地利用规划,土地资源的生态安全得到了一定保障。     

School food environments and the obesity issue: content,structural determinants,and agency in Canadian high schools

To understand the phenomenon of the rapidly increasing prevalence of overweight and obese children and youth, it is especially important to examine the school food environment, the role of structural factors in shaping this environment, and the resulting nutrition and health outcomes. The paper examines research on school food environments in the US and Canada. It notes evidence of widespread availability of poor nutrition products in both environments and delineates reasons for the situation, and examines initiatives presently being undertaken in a number of jurisdictions in both countries to encourage healthy eating in schools. Empirical data are presented from a pilot study of high schools in the Canadian province of Ontario. The study documents the extent of student purchasing of nutrient-poor foods and beverages, and the structural factors internal and external to the school that appear responsible for the availability of such products in food environments in this critical institutional sphere. The paper also examines positive local initiatives in high schools that seek to encourage healthy eating in schools.
