青海省农业农村现代化发展水平研究 总被引：7，自引：4，他引：3
实现农业农村现代化是乡村振兴战略的根本目标,农业农村现代化的快速推进对经济社会可持续发展具有非常重要的意义。以青海省为研究对象,从农业现代化和农村现代化2个层面构建一套包含10项准则、42项具体指标的农业农村现代化评价指标体系,并对2006—2016年青海省农业农村现代化发展水平进行测评,探讨近年来青海省农业农村现代化发展的趋势、短板和不足。结果表明:青海省农业农村现代化发展指数从2006年的0.264到2016年的0.401,年均增长0.014,总体发展水平越来越好;农业农村现代化达标率从2006年的31%到2016年的44%,达标程度为中等。从农业现代化和农村现代化2个层面来看,农业现代化发展水平及达标率要高于农村现代化,但农村现代化发展水平及达标率的增速要高于农业现代化。青海省农业农村现代化的难点是改善农村环境;重点是提高农民收入和完善农业经营体系;每千人拥有的农业科技人员、农林牧渔服务业产值占比、农业投资占农村总投资比重和每万人拥有文化站数4项指标是青海省农业农村现代化的最主要短板。鉴于此,青海省要快速推进农业农村现代化,就必须加快制度创新,改善农村生态环境;加快农业政策转型,强化有效支持力度;加快农业科技创新力度,提升科技驱动能力;优先安排农村公共服务投入,实现城乡协调发展。 相似文献

This paper presents a method that can non-invasively detect artery compliance using oscillometric method.There are also researches about Windkessel theory,and analysis of the combination of Windkessel and oscillometric method.Then the authors summarize a method to calculate artery compliance and introduce the clinical effect in the hospital.Compared with traditional sphygmomanometer,they get the pertinence of SBP is r=0.918 5(P<0.001).And the pertinence of DBP is r=0.899(P<0.001).Then it is compared with ultrasonic method,the pertinence of compliance is r=-0.820 9(P<0.01).This proves that the diagnose of blood pressure and artery compliance is effective and artery compliance is an important index in cardiovascular clinical measurement.So this paper makes the oscillometric method to be applied to wide ranges in calculating cardiovascular indexs. 相似文献

Objective To compare different methods for assessing the compliance of veterinary clients administering medication to their dogs.
Procedure Thirty-one owners whose dogs were prescribed amoxycillin-clavulanate, twice and thrice daily, for a duration of five to seven days were recruited from three Sydney veterinary hospitals. Compliance was assessed by electronic monitoring devices, return medication counts, client self-reports and veterinarians' estimation of likely compliance.
Results Electronic monitoring showed owners administered on average 84% (range 7 to 104%) of prescribed medication to their dogs. Both return medication counts and client self-reports tended to overestimate therapeutic compliance when compared with electronic monitoring. When questioned, the majority of owners (71%) claimed perfect compliance with the prescribed regimen. No correlation was found between veterinarians' estimates of owner compliance and that assessed electronically.
Conclusion Electronic monitoring provided valuable information on dose timing and variation, but proved costly and difficult to employ in veterinary practice. Simplicity and low cost of return medication counts makes this method attractive for use in veterinary compliance studies. Client self-reports reliably detected some noncompliers and permitted identification of individual problems or errors. For practical purposes a combination of return medication counts and client self-reports may have merit in future veterinary compliance studies. 相似文献

为实现柑橘采摘的机械化、智能化,设计了一款欠驱动式柑橘采摘末端执行器。该执行器通过三指充分抓握与偏转的融合控制,实现对不同大小及椭圆度的柑橘的稳定采摘。针对不同尺寸柑橘采摘需求,设计了双连杆并联式手指,在抓握直径差异较大的柑橘时,手指能够自动进行抓取或捏取动作,并实现被动柔顺。通过静力学分析,得到抓取力与电机输出力矩间的关系。针对不同椭圆度柑橘采摘需求,为手指根部添加旋转关节。在建立电机驱动控制系统模型的基础上,提出基于电流反馈的主动柔顺控制策略,指根能够旋转合适的角度使指面与柑橘表面紧密贴合,在防止手指棱边刮伤柑橘表皮的同时,增大接触面积、提高摩擦力。仿真结果表明,该末端执行器结构在运动学方面满足设计要求。制作物理样机并在实验室环境下进行了柑橘抓取试验,试验结果表明采摘执行器针对直径30~100mm的柑橘抓取成功率为98.3%,平均耗时5.3s。该末端执行器能够针对不同尺寸、不同形状的柑橘实现采摘功能,具有适应性强、抓取稳定、不损伤果实等优点。 相似文献

莎士比亚的《暴风雨》在后殖民批评中被看作是殖民主义寓言，其中普洛士帕罗和卡力班分别是殖民者和被殖民者的象征。这个批评视角的形成与加勒比海地区原殖民地作家对《暴风雨》所进行的解读和挪用具有前因后果的关系。文章一方面从加勒比海地区作家莱明、雷塔马、塞萨尔等人的作品中，看殖民地作家在反抗殖民主义、寻找自我意识的过程中，如何对《暴风雨》和西方学者的研究加以挪用，另一方面回到莎士比亚原著，寻找使挪用成为可能的线索。 相似文献

The preliminary results of a study of the endemic giant tortoise population of Aldabra Atoll in the Indian Ocean (Geochehne gigantea Schweigger) are briefly described. Their number would appear to have increased dramatically since the turn of the century to their present level of some 141 000 individuals. Crude estimates of mortality and reproductive rates are also given. 相似文献

In 2003 the Texas Board of Health approved a modification to the Texas Administrative Code that permitted pet owners to have their dogs (Canis familiaris) and cats (Felis catus) vaccinated against rabies every 3 years, provided a triennial vaccine was used. The change had been opposed by hundreds in the veterinary community, some concerned that its implementation would be followed by a decrease in rabies vaccination rates. To determine if this decrease had occurred, rabies vaccination rates for 4 years before and after migration to the 3-year vaccination interval were examined. Data for dogs and cats, ≥ 4 months of age, were collected from the Texas Department of Health Rabies Incident Report database. Each animal's record included its current rabies vaccination status. The number of animals that were currently vaccinated against rabies was tallied and the percent vaccinated was calculated. From 1999 through 2002, 46% of dogs were vaccinated against rabies. From 2004 through 2007, 56% of dogs were vaccinated against rabies. From 1999 to 2002, 18% of cats were vaccinated against rabies. From 2004 to 2007, 30% of cats were vaccinated against rabies. There has been a significant increase in the numbers of dogs (P < 0.001), and cats (P < 0.001), vaccinated against rabies since the introduction of the triennial vaccination interval. This observational study documents the positive changes in rabies vaccination rates following migration from a 1-year to 3-year vaccination interval. 相似文献

Severe equine asthma (SEA) syndrome is a chronic recurrent respiratory disease, common among adult horses. The disease occurs in genetically susceptible individuals after their exposure to organic dust. Thus, environmental management has proved essential in controlling airway challenge and disease exacerbation. This is a demanding process that can only be achieved through the horse owners’ cooperation. One year after initial diagnosis of SEA in a group of 39 horses, owner compliance to an environmental management protocol was evaluated. The overall compliance to the protocol was poor and the horses’ clinical health and need for pharmacological management was related to the successful implementation of the environmental recommendations provided on disease diagnosis. 相似文献
