洞庭湖湿地景观特征与农业产业化模式研究   总被引:1,自引:0,他引:1  
洞庭湖湿地是我国最大的淡水湖泊湿地景观生态系统之一,湿地农业资源丰富,农业开发历史悠久,生产化水平较高,是我国重要的农业商品基地。由于过去长期受传统耕作方式的影响,农业产业化程度较低,农业经济发展缓慢;本文根据洞庭湖湿地景观特征,对洞庭湖湿地农业资源和湿地农业开发现状进行了评价和分析,指出了湿地农业开发中存在的问题,提出了洞庭湖湿地农业产业化开发利用模式,以实现洞庭湖湿地农业经济的飞速发展。  相似文献

20世纪 30年代 ,南京国民政府与乡村建设派合作 ,掀起了一场县政建设运动。其中 ,五个实验县各有特点 ,但是 ,由于乡村社会结构的变动和国家政治结构变动并未出现地域性的根本差别 ,因而 ,尽管在具体的进程和操作方式上有所区别 ,甚至在参与力量和主体上也有所不同 ,县政建设运动整体上却有着共同的历史特征。它的运作模式、实验方式和实验内容都为中国乡村现代化留下了许多历史经验和教训  相似文献

Why do farmers intensify their agricultural practices? Recent revisions of African environmental historiographies have greatly enriched our understanding of human–environmental interactions. To simply point at poor farming practices as the main cause of deforestation, desertification and other processes of land degradation is, for example, no longer possible. The contemporary analytical focus is instead on the complex and often unpredictable set of causal relations between societal, ecological and climatic factors. In the literature on agricultural intensification, conventionally defined driving forces, such as population pressure and market demand, remain important explanatory factors despite a growing body of research that suggests more dynamic scenarios of agricultural development and landscape change. This article reports on a case where the common‐sense logic of population pressure theory has dominated the historical narrative of a local process of agricultural intensification among an agro‐pastoral people in north‐central Tanzania. By way of a ‘detailed participatory landscape analyses’ a more complex and dynamic historical process of intensification is suggested, in which the landscape and the process of agricultural intensification itself are in focus. It is concluded that the accumulation of landesque capital has been incremental in character, and that the process of agricultural intensification in the study area has largely been its own driving force based on self‐reinforcing processes of change, and not a consequence of land scarcity and population pressure. This result demonstrates the possibility and usefulness of reversing the Bose‐rupian argument in analyses of agricultural intensification.  相似文献

This paper summarizes recent archaeological research efforts, and changing perspectives, about the native history of the Caddo peoples who lived in the Caddoan Archaeological Area, which centers on the Great Bend of the Red River in Oklahoma, Texas, Arkansas, and Louisiana. Of particular focus are the origins and early developments of the Caddoan tradition, regional diversity, subsistence changes and agricultural intensification, sociopolitical dynamics, and Caddoan-European interaction.  相似文献

This paper reviews new developments in the study of modern Chinese history since 1979, especially key questions in modern Chinese history, together with innovations in content, structure and research methods. These new developments reflect the broadening of academic exchanges with foreign countries, the initiation of reforms, the influence of the modernization process, and far-reaching innovations in the discipline of modern Chinese history studies since the reform and opening-up of China.  相似文献

The development of tourism can have a considerable sociocultural impact on ethnic communities, but few studies have attempted to separate the unique impact of ethnic tourism from the overall impact of modernization and describe its mechanism clearly. This paper describes a quasi-natural experiment performed in three typical Dai villages in different stages of tourism development. A crosswise and longitudinal comparative study was performed on Dai village culture. The study indicates the following: (1) spiritual culture has been transmitted relatively unchanged across generations in three Dai villages, but material culture has undergone various degrees of change. (2) The changes in material culture and some parts of institutional culture have been caused primarily by the pressure of overall social modernization. (3) Currently, the overall thrust of modernization in mainstream Chinese society has driven some ethnic cultural practices out of use, while the endogenous driving force of tourism development in ethnic communities has pulled them back into use. (4) Under the influence of modernization, the issue of whether ethnic tourism communities can be developed in a sustainable way depends on both bottom-up and top-down factors: the leading role played by community elites internally, developing useful parts of ethnic culture and discarding useless parts during repeated games in the tourism field, and government policy and guidance facilitating planning.  相似文献

基于面板数据,从综合系统-子系统-要素等三方面定量测度省域人口、土地与产业城镇化对农业农村发展的影响程度,深入剖析城镇化不同要素对农业与农村系统发展的作用机理。研究结果表明:①人口城镇化与产业城镇化对农业农村的影响更加明显,对农村生活系统影响的弹性系数大于1的地区比重分别为58.06%和64.52%;土地与产业城镇化对农业生产系统产生负向影响较为明显,弹性系数小于0的地区比重分别为29.03%和38.71%;②城镇化率、产业结构和建成区比重对人均耕地面积、乡村劳动力比重和人均粮食产量呈显著负相关,与农民人均纯收入、人均农业产值和单位面积机械动力呈显著正相关;③通过深入分析近30年省域城镇化对各地区农业农村发展的作用机理,对于新时期新型城镇化、农业农村转型发展等战略的贯彻落实具有重大的现实意义。  相似文献

农业生产空间是农村基本功能的载体。从资本“三重循环”视角出发,将“空间的生产”理论引入农业研究,提出并构建农业空间生产资本化的作用逻辑及其特征表征,并以山东省泰安市村庄为研究单元,研究其农业空间生产资本化特征、模式表征及空间规律。发现,泰安市农业生产具有资本投入集约化、空间生产集中化、组织分工专业化等特征;农业空间生产资本化模式共有四种,在空间上呈现出以中心城区为圆心,圈层式向外拓展的规律性,农业空间生产资本化度和三重特征都表现出由内向外先增后缓降的格局。在乡村振兴背景下,识别村庄农业发展模式,根据要素条件,分类指导农业种植结构调整,有利于促进农村多功能有机融合,实现乡村农业产业兴旺发展目标。  相似文献
