农业生产基地项目环境影响评价要点分析及探讨

农业生产基地项目具有影响范围大、产品服务多元化等特点，涉及行业类别较多，其环境影响评价文件也相对复杂。环境影响评价报告编制单位应充分与建设方进行沟通，熟悉项目建设内容，挖掘项目可能的产生污染的环节和设施，明确环境影响范围和环境敏感点，并对项目损益进行两方面的分析。

The genetic diversity and structure of 18 sheep breeds exposed to isolation and selection

The phylogenetic layout of the genotyped (30 microsatellite) 18 sheep breeds in this study demands and provides the opportunity to evaluate both neutral and adaptive components of genetic diversity in a naturally and artificially selected and subdivided sheep population. Seven Pramenka strains from Bosnia and Herzegovina and Croatia characterized by a very low intensity of artificial selection, preserved the highest neutral genetic variability. Eight central and north‐western European breeds under considerable artificial isolation and selection preserved the lowest genetic variability. Only combinations of various phylogenetic parameters offer a reasonable explanation for underlying evolutionary forces working in the investigated island and mainland sheep breeds under variable natural and artificial selection. More than 60% of total genetic, diversity was allocated to virtually unselected Pramenka strains, and an additional 25% to native moderately selected Graue Gehoernte Heidschnucke and intensively selected Ostfriesische Milchschafe. Some economically very important breeds and strains did not contribute to a pool with maximal genetic diversity, while they play an important role in the cultural heritage of respective countries.     

酶制剂在农业中的应用及生物技术改良

提高农业科技服务能力 推进农村小康社会建设

中国全面建设小康社会重点在农村，难点在如何增加农民收入，很大程度上取决于如何为八亿农民提供农业科技服务，促进农业技术创新和科技成果转化为现实生产力。本文从中国农业生产的现状、科技服务“缺位和滞后”和力量不足等问题入手，提出改革现行的农业科技运行和转化机制、开展科农携手共建利益共同体、发挥示范榜样作用、提高劳动者的科技素质等对策，促进科学研究面向生产第一线和科技成果直接应用于生产，为农民提供全方位、多层次、多领域的科技服务，推进农村全面建设小康社会进程。

A model of decision-making and information flows for information-intensive agriculture

This paper describes the development of a systems based model to characterise farmers’ decision-making process in information-intensive practices, and its evaluation in the context of Precision Agriculture (PA). A participative methodology was developed in which farm managers decomposed their process of decision-making into brief decision statements along with associated information requirements. The methodology was first developed on a university research farm in Denmark and further revised during testing on a number of research and commercial farms in Indiana, USA. Twenty-one decision-analysis factors were identified to characterise a farm manager’s decision-making process. Then, a general data flow diagram (DFD) was constructed that describes the information flows “from data to decision”. Illustrative examples of the model in the form of DFDs are presented for a strategic, a tactical and an operational decision. The model was validated for a range of decisions related to operations by three university farm managers and by five commercial farmers practicing PA for cereal, corn and soybean production in Denmark and in Indiana, USA.     

试论农业机械化在建设社会主义新农村中的重要作用

建设社会主义新农村,是党中央从贯彻落实科学发展观、构建社会主义和谐社会的全局出发作出的重大战略部署,农业机械化发展必须适应农业现代化和建设社会主义新农村的需要,为我国实现农业现代化、解决“三农”问题,建设社会主义新农村作出农业机械化应有的贡献。
