为了满足天气、气候需要的基本气象资料,形成天气、气候要素长期、连续和稳定可靠观测能力,必须进一步提升我国地面气象观测的自动化水平。新型自动站按照统一标准、统一功能、统一结构、统一方法、统一规范的设计思路,做到各部件或模块互换的自适应,形成统一型号的新型自动气象(气候)站,达到满足现有气象观测站的气候观测、天气观测和区域观测业务的需要。以自动气候站为基础,采用当今成熟的、稳定的、先进的电子测量、数据传输和控制系统技术,设计基于现代总线技术和嵌入式系统技术构建的自动气象站,满足地面气象观测全要素自动观测。 相似文献

猛地一看,法国北部那个特殊区域的中心位黄特别象一个大型奶牛场的挤奶厅。工作人员站在大厅中央一个下陷的深坑里工作,坑的周围环绕着畜栏。近距离观察能够发现每个动物都为其配备了泵和管子等自动装备。 相似文献

利用常规气象观测资料、卫星遥感监测图和地面自动气象站资料分析了2017年春季发生在内蒙古通辽地区的一次强沙尘暴天气。分析结果发现,该次沙尘暴的主要影响系统是地面冷锋和蒙古气旋,高空急流及地面较强气压梯度有利于大风、沙尘暴的加强,散度场以及假相当位温分布特征分别为强沙尘天气提供有力的动力条件和热力条件,地形特征、前期气候条件和具有沙尘源的下垫面是形成沙尘暴的物质基础。卫星遥感和地面自动气象站的实时监测对沙尘暴具有指示意义;大风和沙尘暴对农业及生产生活造成一定影响,也破坏了草原生态环境和畜牧业生产。 相似文献

The present study explores the welfare aspects of involuntary milking in dairy herds with an automatic milking system (AMS) as it focuses on whether fetching of cows for milking may be related to fear/discomfort of the automatic milking unit (AMU) or the milking itself and further, may strain the human–animal relationship. Behavioural data on cow reluctance when entering the AMU, stepping and kicking behaviour during milking and avoidance of humans was collected at 6 two-day visits to 8 Danish commercial AMS herds during a year. The data set for the analysis included one observation per cow of reluctance when entering the AMU and behaviour during milking of a total of 869 cows; 255 cows fetched for milking and 614 non-fetched cows. For 82 of the cows fetched for milking and for 370 of the non-fetched cows the data further included one observation per cow of avoidance towards an approaching unfamiliar human in a test situation. Multivariate analyses by conditional hierarchical log-linear models showed that fetchings were more frequent the first 14 days of lactation (P < 0.001). The multivariate analysis showed no associations between fetching and reluctance at entering the AMU, nor an association to stepping and kicking during milking. However, compared to non-fetched cows, fetched cows were more frequently avoiding the test person in the human approach test (P < 0.001). It is concluded that fetching may strain the human–animal relationship. 相似文献

We studied the effects of baiting on feral swine (Sus scrofa) movements and corresponding likelihood of disease spread under real and simulated culling pressure. Our objectives were to determine the proportion of feral swine that used the bait station site, and if baiting of feral swine altered areas of utilization, distances from location centroids to treatment location (control or bait station), and movement rates by survivors during culling activities. We hypothesized that the bait station would increase the sedentary nature of feral swine, thus reducing the potential for dispersal and hence disease dispersal. Our experiment was conducted between February and May 2011 on the Rob and Bessie Welder Wildlife Foundation (WWF) in San Patricio County, Texas. We trapped 83 feral swine and placed GPS collars on 21 animals. We established and maintained a centralized bait station on one side of the WWF from 13 March to 27 April. We conducted population-wide culling activities, including trapping, controlled shooting, drive shooting, and aerial gunning, from 3 to 27 April and removed 143 feral swine (4.6feral swine/km(2)). Areas of utilization did not differ between treatments (control or bait station). However, we found location centroids of bait station site feral swine to be closer to the treatment location than those of control site animals and daily movement rates of bait station site feral swine to be 39% greater than movement rates of control site animals. Based on our observation that only 62% of feral swine trapped in proximity to the bait station used it, we cannot recommend baiting as an alternative to fences for containing animals during culling activities. However, there is value in using bait stations to describe patterns of feral swine movements, facilitate observation, and improve efficacy when conducting removals. 相似文献
