农业地质是以地质理论为基础与大农业专业理论相结合以解决农业相关问题，服务于农业，以在农业生产实践中获取最大的社会和经济效益。虽然我国正在广泛开展农业地质调查获取了较多的农业地质信息，但信息利用程度低，发挥的经济效益不够理想。分析了在我国开展农业地质研究的意义及其存在的问题，并就农业地质信息在农业区划中的应用进行了探讨。 相似文献

<正> 新兴的农业地质背景学是地质与农业相结合的一门边缘学科。早在我国古代,人们就已认识到农业生产与自然地理和土壤的关系。十九世纪中叶,欧洲地质学家法鲁(F.A.Fellow)和李希霍芬(F.V.Richthofen)等提出了仅用于研究土壤发生关系的“农业地质”概念,当时被称为“农业地质学派”。随着科学技术的进步和农业的发展,它已成为研究农业地质背景规律与农业生产过程相互联系、相互制约、相互作用的内在相关因素的科学。 相似文献

In spite of the predominance of agriculture in the economy of Pakistan, animal raising is the most neglected industry in the country. The study points out some of the reasons for such neglect and lack of enthusiasm in organizing the cattle industry. Cost and return method has been used to relate the importance of crops over livestock in the farm economy. 相似文献

This paper critically examines some of the causes and the problems of agricultural development in Nigeria. It also discusses
very minimally, the rise and the contribution of the petroleum industry to the Nigerian economy and its effect on the agricultural
sector. Finally, some possible suggestions are made in order to ameliorate the situation of agriculture and to overcome the
shortage of food production in the country. 相似文献

The article examines some of the main trends of the modernisation of agribusiness and raises some questions about geographical transformations taking place in the centre and north of Brazil. The country represents an emblematic case of neo-liberalised agriculture in need of further investigation. It is discussed in the text how corporate, industrial-scale agribusiness practices in Brazil bring back some spectral elements of capitalism, which never disappeared and in which the invisible becomes visible again. It is a phenomenon of multiple dialectics that needs further theoretical, methodological and investigative elaboration. The most dramatic circumstances, and most interesting for academics to study, are at the frontier of the expansion of agribusiness, where spatially and temporally patterns are heterogeneous and largely unpredictable. Agribusiness is especially promoted at the agriculture frontier in Brazil because it is in itself an economic, ecological and ethical frontier. Therefore, critical research into the complexity of contemporary agribusiness should really be about the political economy of alternatives to the highly vulnerable and unsatisfactory approaches to food and agriculture that prevail today and continue to expand unabated. 相似文献

The paper summarises the East European experience with socialist agriculture and notes that while production often failed to meet plan targets (thereby giving the impression of a sector in crisis), there was steady growth based on substantial investments in buildings, machinery, fertilisers and irrigation systems which provided food for the population at affordable prices. The increased spending power of higher salaries during the 1970s and 1980s also drew a positive response from agriculture in the context of significant reforms which, unintentionally, contributed to the demise of the communist system in 1988–1990. Transition to a market economy has cast agriculture into a state of great uncertainty through restitution and the end of price controls, combined with the disruption of trade contacts with the Former Soviet Union. Falling real wages have reduced demand while the overtures being made to the European Union (with its substantial food surpluses) suggest that reduced agricultural output may be a permanent reality. In this case the thrust of rural development will have to give more attention to the quality of the environment and the provision of alternative employments for country dwellers. It remains to be seen how far small family holdings can be maintained in the context of farm diversification and pluriactivity. 相似文献

Variations in frequency and intensity of extreme events have substantial impact on water resources and environment, which in turn are reflected on agriculture, society, and economy. We assessed spatiotemporal changes in pattern of daily precipitation to identify drought- and flood-prone areas of Iran. To do this, we generated gridded daily precipitation for the period of 1962–2013 over Iran using measured daily precipitation and the Kriging approach. We applied 11 precipitation indices that were stated by the Expert Team on Climate Change Detection and Indices (ETCCDI) to identify significant changes in frequency and intensity of extreme precipitation events. According to significant changes of these 11 precipitation indices, drought- and flood-prone areas of Iran were, then, detected. We observed significant changes in pattern of daily precipitation over more than half of the country. 40% of the country, which were located in the elevated regions of Iran, particularly along Zagros Mountain, was identified as flood-prone areas. As a result, in these regions, there is a need for flood risk management based on changes in stormwater events such as runoff generated from rain on snow and snowmelt events. In addition, we detected drought-prone areas in large portion of the northwest of Iran and in the low elevated regions of the country that have semiarid or arid climate. This suggests that it is necessary to prepare a long-term drought plan to mitigate impacts of severe drought events. 相似文献
