基于因子分析和DEA模型的现代光伏农业技术经济性综合评价研究

发展现代光伏农业是推进现代农业可持续发展的重要途径，对现代光伏农业进行技术经济性综合评价有较强的现实意义，为此，建立了因子分析法和DEA相结合的现代光伏农业技术经济性综合评价模型。首先，利用因子分析法对评价指标进行了降维处理；然后，根据DEA模型需要对指标数据进行了标准化处理；最后，利用DEA模型完成了对50亩智能农业大棚各经营方案的评价，结果表明：将光伏发电和温室大棚种植相结合具有良好的技术经济效益。     

The commercialisation of subsistence farms: Evidence from the new member states of the EU

For selected regions of five EU Member States (Bulgaria, Hungary, Poland, Romania and Slovenia), this paper examines the determinants of the commercialisation of (semi)subsistence farms. While subsistence farming has become an important feature of the EU, there is a lack of evidence on its spatial distribution, importance and reasons for persistence. The analysis utilises cross-regional survey data and qualitative interviews. Results suggest the absence of a subsistence poverty trap driven by either farmer perceptions or transactions costs although capital endowment appears to play a significant part. On the other hand the degree of market engagement depends on access costs, which vary with location, households’ productive assets, specialisation, and risk propensity. Implications for land use policy are discussed.     

区域休闲农业旅游开发的风险评价——以浙江省为例

风险是区域休闲农业旅游开发不可回避与亟待探究的问题。为深化区域休闲农业旅游开发风险的认识与实践,研究以休闲农业旅游开发较为成熟的典型地浙江省为案例,运用数据包络与因子分析方法,在对区域休闲农业旅游开发当前效率与未来潜力进行评价与分析的基础上,借助合图法以效率与潜力为聚类指标,通过两者比较对浙江省休闲农业旅游开发风险进行整体分析和评价,并将其划分为休闲农业旅游低风险积极开发、较低风险适宜开发、一般风险适度开发和较高风险整合开发等4类区域。最后,总结浙江省休闲农业旅游开发风险特征为:(1)开发风险与区域经济发展水平和区位优势条件存在明显的相关关系;(2)区域间经济社会相关联系程度影响开发风险分布方向;(3)开发水平在空间上存在较强的收敛性特征,并从中提炼出明确区域休闲农业旅游开发方向、营造良好区域交流与合作环境和构建区域休闲农业旅游开发风险协同管理机制等开发风险规避策略。     

吉林省农业生态旅游功能分区研究  谢 璐

随着我国城镇化进程的不断加快,生活在喧嚣都市的人们越来越向往恬静的田园风光,农业生态旅游业作为一种新型农业生产经营形式与旅游活动项目应运而生,并且越来越受到相关学者与政府的重视.文章以吉林省农业生态旅游为研究对象,分析了农业生态旅游的发展现状,指出其发展存在生态环境破坏、 基础设施落后、 管理水平较低、 产业链条较短等问题;综合考虑吉林省地形地貌特征、 气候特征、民俗风情等因素,考虑不同区域农业经济、 社会、 生态及文化的相似性与差异性,对其进行地理空间分区,大致分为东部长白山农业生态旅游功能区、 中部松辽平原农业生态旅游功能区、 西部松嫩平原农业生态旅游功能区,同时探究了各功能区的差异性特征;针对各功能区不同特征提出"政府调控-市场调节"相互配合、"农业-旅游业"相互耦合、"经济-社会-生态"相互协调、"以点带面"互联互动、"省内-省外"互学互助等发展建议,以期为当地农业生态旅游的发展提供借鉴,为促进吉林省农业生态旅游业的可持续发展提供参考.     

Agriculture and the city: A method for sustainable planning of new forms of agriculture in urban contexts

Contemporary cities are threatened by urban development decreasing the overall environmental quality and fragmenting natural and agricultural landscapes. As a result of this fragmentation the number of Non Urbanized Areas (NUAs) present in urban contexts is dramatically decreasing. These areas include cultivated land, Abandoned Farmlands, Grassland, Woods and Shrubs that are often located at the peri-urban cities’ fringes. Among NUAs, farmlands and other forms of urban and peri-urban agriculture provide all three major categories of ecosystem services, provisioning, regulating and cultural services. Recently, New Forms of Urban Agriculture (NFUA) have gained increasing attention from researchers for their promising multifunctionality. Incorporating NFUA into the urban environment will thus improve the sustainability of cities, taking advantage of the multiple benefits and services they can provide.This paper presents a method for the characterisation of NUAs in terms of their physical, ecological and social features. These areas are analysed with different criteria and related indicators structured according to a GIS-based Multi Criteria Suitability Model. The proposed model checks the suitability of transformation of the NUAs toward NFUA, thereby enhancing their ecological and social function as well as accessibility and overall connectivity. Different scenarios of spatial configurations for NFUA have been explored with a sensitivity analysis on the values of used indicators. The method was tested for the municipality of Catania, south Italy, an urban context characterised by a relevant shortage of public green spaces and services.     

我国休闲农业产业化发展研究:述评与启示 

休闲农业为农业的发展注入了活力,成为农业转型升级、实现农业现代化的重要途径。休闲农业的巨大潜力就在于其多功能性,通过对农业生产活动、农村田园风光、农家生活、农耕文化的资源整合、科学规划及创新开发,能够满足城市居民观光娱乐、休闲度假、农事体验、学习教育、康体怡情等多重需求。休闲农业的未来之路将走向何处、如何走的问题自然而然地成为国内文献研究的一个热点,但研究水平参差不齐。一方面,目前对休闲农业的概念、产业属性、发展原则等具有决定性作用的基础性问题的认知上仍存有诸多分歧;另一方面,有些学者却已高瞻远瞩发现了休闲农业的未来趋势将走向产业化发展道路,并对休闲农业产业化发展的路径与组织方式进行了探讨。文章在总结反思国内文献研究成果的基础上,对休闲农业的概念、产业属性、发展原则及产业集群式的产业化发展路径与多元化的组织形式进行了述评,并得出几点启示,以期促进相关学术研究的深化。     

Leisure in Living Local through Food and Farming

This article reflects on aligning leisure research with the local foods movement while placing the local foods movement into the larger framework of sustainability and the fields of leisure and recreation. The local foods movement has persisted during difficult economic times; growth in local foods venues and young people endeavoring to establish small-scale sustainable farms continues to flourish. Given the history of leisure research and its continued success alleviating participation barriers and constraints, the need for leisure researchers to focus on local food systems is imperative and timely. This essay highlights the notion of leisure in living through local foods and the serious leisure aspects of small-scale sustainable agriculture. This article also encourages leisure researchers to explore and assess the relationships between the local foods movement and small-scale farming as embedded in the larger framework of sustainability.     

文化传统与秦国农业的发展——中国传统文化软实力研究之一

秦国农业发展成就的取得与其文化传统密切相关。关中地区"好稼穑、务本业"的社会风尚奠定了秦国农业发展的文化基础;秦文化重功利的价值取向使秦国的农业激励政策发挥出了最大效能;宗法观念淡薄则使个体小家庭生产这种最适应生产力发展水平的经营方式在秦国得到了最彻底的推行。     

农业剩余转化与动态发展牵扯:以工补农新机制解析

"以工补农"不能单纯地从同情"三农"态度出发研究"单向的以工补农",而应从深入剖析工业化过程中的工业和农业互动关系出发,积极探索"双向的以工补农"机制。从工业化过程中工农互动机制中寻找到一个"以工补农"机制的新视角,通过构建基于工业化的"农业剩余转化"模型,重点分析工业化过程中的农业剩余转化和农业深化发展动态关系的"以工补农"机制。在工业化过程中,要根据工农关系不同阶段的特征,采取不同的工农互动关系调节方法,即不同的"以工补农"策略,促进工业和农业互动协调发展。
