风电场环境影响评价原则及评价重点研究

针对风电场环境影响评价的评价原则及评价重点进行了探讨性的研究。提出了风电场环境影响评价应以早期介入和避让措施优先为基本原则；对风电场环境影响评价重点进行了识别，并提出风电场选址的环境可行性分析是风电场环评的重中之重；风电项目建设对生态环境的影响及风机噪声、光影影响也是风电场环境影响评价的重点，并创造性的提出风机噪声光影联合防护区的概念，以期对风电场环境影响评价提供理论及技术参考依据。     

Traditional agriculture in transition: examining the impacts of agricultural modernization on smallholder farming in Ghana under the new Green Revolution

Following the renewed effort at achieving a new green revolution for Africa, emphasis has been placed on modernizing smallholder agriculture through the deployment of improved inputs especially mechanized technologies. In Ghana, the government has in the last decade emphasized the provision of subsidized mechanized ploughing services to farmers alongside a rapidly growing private sector tractor service market. While mechanized technology adoption rates have increased rapidly, the deployment of these technologies has been without critical analysis of the impacts on production patterns and local agrarian systems. This paper examines the distributional impacts of agriculture mechanization on cropping patterns and farm sizes of smallholder farmers in northern Ghana using Geographic Information Systems (GIS) techniques, and semi-structured interviews with smallholder farmers (n=60). Specifically, comparative analysis of the field sizes and cropping patterns of participant farmers prior to and after the adoption of mechanized technologies was conducted. In-depth interviews were used to contextualize the experiences of smallholder farmers toward understanding how mechanization may be impacting traditional agriculture. Our findings reveal a mechanization paradox in which farm sizes are expanding, while cropping patterns are shifting away from traditional staple crops (pearl millet and sorghum bicolor) to market-oriented crops (maize, rice and groundnuts). This transition we argue, has adverse implications on the cultural dimension of food security, the organization of social life, and climate change adaptation. We recommend a retooling of the current agricultural policy focus to ensure context sensitivity for a more robust battle against food insecurity.

中国风电的时空分布特征和发展趋势

利用1990-2005年中国和英国风电发展数据,对两国风电的时空分布特征和发展趋势进行了比较分析。据英国风电发展的阶段性,把中国风电发展划分为试验性发展、规模发展、过渡发展3个阶段,并预测到2007年步入大规模发展阶段。因此,未来几年,中国风电场数目和规模将会快速增长,并且由集中走向高密度集中分布。据对影响风电场省级时空分布的自然、市场和政策共8个选择因子的主成分分析和系统聚类分析结果,将中国风电场按省级划分为3个区域和8个亚区域,对聚类结果进行逐步判别回判,结果表明准确率达92.6%。
