乐山市休闲农业发展现状浅析

现如今,随着经济社会的发展,人们的经济水平不断提高,同时竞争压力也在不断增大,促使人们愿意将更多的时间用于放松和自我提升。以农业活动为基础的休闲农业,是一种把农业和旅游业相融合的一种新的放松休闲方式,其将自然环境、农事活动、绿色食品、乡土文化相融合,不断吸引并成为人们外出休闲的最佳选择。乐山市近年来以“农业”为基础,以“绿色”为指引,将茶叶、水果、水产、蔬菜、林竹等特色农业产业联结,推动农业产业体系,从而促进休闲农业的发展。本文结合乐山市发展休闲农业模式分析,探索出休闲农业发展存在不足,并以此为基础提出可行的发展建议,为乐山市打造休闲农业总体发展提供借鉴和参考。

商代的生态环境与农业发展

从整体上看,商代的生态环境处在"中国全新世大暖期".但在长达约600年的商代历史中,以气候为主要因子的生态环境也出现有不小的波动,表现为商代早期出现有短暂的干旱,中期到后期有较长时期的温暖适宜期,商末环境又有转为干旱的迹象.商代的生态环境对农业生产有直接的影响,形成了"粟稻混作区".商代农业确定了中国古代农业发展的方向,并为商王朝的崛起和兴盛奠定了坚实的基础.

1870～1914年间英国各农业阶层状况考察

1870-1914年间,英国农业历史的基调是“农业大危机”。“大危机”并非全面的危机,而是英国农业结构的调整——从谷物生产向畜牧业生产转变。它具有复杂的多样性,不仅表现在地区和产业方面,还表现在农业阶层的活动方面。经历过大危机的各农业阶层,包括地主、农场主、农业工人各自做出了不同的反应,各自的得失也有较大差别。

WHY IS THE MINARET SO SHORT? EVIDENCE FOR EARTHQUAKE DAMAGE ON MT ZION

Abstract

On top of King David's Sepulchre at Mt Zion there is an Ottoman minaret known as al-Nabi Da'ud. Compared with other minarets in Jerusalem, al-Nabi Da'ud seems to be somewhat shorter, and has a squat-like appearance. To track why it is shorter than other minarets, we inspected written historical sources, a sequence of old drawings dated between the mid-eighteenth and mid-nineteenth centuries and analysed the minaret's metric proportions. In drawings dated to and before 1833, the minaret is portrayed much higher than in drawings and photographs dated to and after 1838. Furthermore, comparative height-diameter ratio of various parts of the minaret does not fit those of its counterpart, the al-Qal'a minaret. Thus, we suggest that the minaret was originally built higher but damaged during the 1834 earthquake, and reconstructed to a lower height sometimes afterwards.     

Tourism and sacred landscape in Sagarmatha (Mt. Everest) National Park,Nepal

Abstract

While tensions between the sacred and the profane in tourism have been of long standing interest to tourism scholars, there is a dearth of literature on the growing influence of tourism on local residents’ spirituality and religious practices in sacred landscapes. This paper examines how local residents’ interpretations of sacred landscapes are influenced by tourism development, and whether tourism plays a role in influencing and reproducing sacred landscape and place-based spiritual values. This exploratory study is based on four months of fieldwork conducted in 2014 and 2015 in Sagarmatha (Mt. Everest) National Park in Nepal’s Khumbu Region. Results of the 33 interviews conducted with ethnic Sherpa community indicate the Sherpa consider their homeland as a beyul (sacred, hidden valley), and its landscapes (i.e. mountains, forests and lakes) as the abode of local deities. Tourism’s influence on local spiritual values is evident and reflected in changes in mountain deity worship, shift in human-environment relationship, and alterations in religious routines and practices. Although Sherpa still regard Khumbu as a sacred place and are actively involved in maintaining their spiritual values and cultural identity, the religious influence of beyul is slowly diminishing as reliance on tourism grows.     

中国古代青金石颜料的电镜分析

Hydrothermal control on organic matter alteration and illite precipitation, Mt Isa Basin, Australia

Abundant illite precipitation in Proterozoic rocks from Northern Lawn Hill Platform, Mt Isa Basin, Australia, occurred in organic matter‐rich black shales rather than in sandstones, siltstones and organic matter‐poor shales. Sandstones and siltstones acted as impermeable rocks, as early diagenetic quartz and carbonate minerals reduced the porosity–permeability. Scanning and transmission electron microscopy (SEM and TEM) studies indicate a relation between creation of microporosity–permeability and organic matter alteration, suitable for subsequent mineral precipitation. K–Ar data indicate that organic matter alteration and the subsequent illite precipitation within the organic matter occurred during the regional hydrothermal event at 1172 ± 50 (2σ) Ma. Hot circulating fluids are considered to be responsible for organic matter alteration, migration and removal of volatile hydrocarbon, and consequently porosity–permeability creation. Those rocks lacking sufficient porosity–permeability, such as sandstones, siltstones and organic matter poor shales, may not have been affected by fluid movement. In hydrothermal systems, shales and mudstones may not be impermeable as usually assumed because of hydrocarbons being rapidly removed by fluid, even with relatively low total organic carbon.     

乡村旅游地空间生产与村民角色转型的过程与机制——以丹霞山瑶塘村为例

乡村旅游空间与村民社会角色是一个相互形塑和建构的过程,揭示两者的互动机制对乡村旅游地可持续发展具有重要意义。研究发现,乡村旅游地空间经历了农业生产空间、农旅并存空间、旅游消费空间的演变过程;村民角色从\"农业生产者\",经不同转型轨迹,归于\"旅游从业者\"角色。权力、资本和市场等主体对乡村旅游空间的建构,对村民角色扮演提出新的期望和规范;村民主体的微观权力、资本积累、个人技能、个人观念影响其角色扮演与空间适应;不同角色村民主体通过微观空间生产行为,促使乡村旅游空间景观化、商业化和制度化,也会产生民宿空间分异和乡村公共空间侵占等问题。     

“金陵根本重地”——明末政治语境中的风水观

自三国时代起,作为南京地区地理标志的钟山就被赋予了风水学的内涵。随着明太祖朱元璋(1328-1398年)将孝陵营建于此,钟山在明代风水堪舆理论中便有了更为丰富的意义。有明一代,孝陵与钟山的意义绝非止于帝王陵寝和自然景观,它们不断为文学传统、仪式制度、风水堪舆、地理象征、政治语汇所利用,并且在这个过程中被赋予政治影响力。     

Studies on amerindian dogs, 1: Carbon isotopes in relation to maize in the diet of domestic dogs from early Peru and Ecuador

Work initiated purely as a dating project in support of a craniometric and morphological investigation of domestic dogs from early Peru has proved to have much wider implications. The stable carbon isotoperatios (¹³C/¹²C) of hair samples from ten dogs show that maize formed a significant part of their diet. Radiocarbon dates for these remains have confirmed that they belong to the period well after the cultivation of maize was first established. Stable carbon isotope measurements can thus be used to test for the presence of maize as a dietary constituent at earlier sites even where there is otherwise only indirect evidence for its cultivation. Collagen from animal or human bone is a suitable alternative to hair for this purpose and the method has been successfully applied to collagen dating to c. 3000 BC from the Valdivia culture site of Real Alto, Ecuador, as well as to a series of early Peruvian dogs.
