天水地区野生动物物种多样性及持续发展策略

天水地区地处陇南山地向陇中黄土高原的过渡地带,野生动物物种多样性丰富.根据调查及有关资料,天水地区共有307种野生动物,占甘肃野生动物总种数的41.88%,其中国家Ⅰ级重点保护野生动物6种、国家Ⅱ级重点保护野生动物38种.针对目前天水地区野生动物保护中存在的问题,提出了加强宣传教育和法制管理、保护生境、扶持和引导社区经济、加强科学研究、处理好资源保护与合理开发利用的矛盾等发展策略.     

人类发展指数的修正与可持续发展的替代指标

本文确认了全球社会-生态问题(过度消费,道德危机)的主要根源并提出了新的可持续发展的愿景,重点要关注精神、道德、心理、生理和人的智力开发(而代替以消费为导主的理念)。讨论了人类发展指标不足所涉及到的因素(寿命预期、人均国内生产总值),提出了测量人类可持续发展的替代指标,即:健康人口的比例。生态效率也被建议作为转化可持续发展的必要条件,人的精神,根据生态中心立场(社会-生态幸福)。通过适当的教育和体制政策而实现环境和人类健康、公平和整个人类的发展。     

Development and Adoption of a Simple Nonpoint Source Pollution Model for Port Phillip Bay,Australia

New computing tools and approaches allow tailored development of software to meet the needs of environmental managers. The processes required for such tailoring fit well with adaptive management concepts where, as knowledge and system understanding develop among managers, the software can be developed or replaced to match. This paper reports on development and adoption of a simple nonpoint source pollution modeling tool, including technical aspects of data support for modeling and social aspects of software design. The software, named FILTER, used a unit load model to generate expected pollutant loads from subcatchments of Port Phillip Bay, Australia. Monitoring data were used for calibration to modify the delivery of generated pollutants to receiving waters. Spatial, tabular, and charting software components were used to provide alternative forms of output visualization. FILTER was developed using a process that resulted in manager-stakeholders taking responsibility for setting of model parameter values and operation of the user interface, thereby encouraging uptake. The inclusive development process, tailoring of the software to manager needs and styles of usage, and matching of model complexity to data and knowledge, resulted in a successful application that has become the current agreed system representation among disparate stakeholder organizations.     

Variation in the Parameters of the Life Cycle in Prawns of the Genus MacrobrachiumBate (Crustacea, Palaemonidae)

Variations in the parameters of the life cycle in freshwater prawns of the genus MacrobrachiumBate and some populations of the species Macrobrachium nipponense(De Haan) were analyzed comparatively. Using factor analysis, these parameters were systematized and expressed through two factors. The first factor is related to the parameters of larval development and the dimensions of an egg, and the second, to the length of adults and their fecundity. The greatest differences in the values of intrageneric and intraspecific variation of parameters are noted for the dimensions of larval stages. It is assumed that the formation of a species proceeds primarily through the appearance of adaptations at larval stages.

The Ethics of Constrained Choice: How the Industrialization of Agriculture Impacts Farming and Farmer Behavior

The industrialization of agriculture not only alters the ways in which agricultural production occurs, but it also impacts the decisions farmers make in important ways. First, constraints created by the economic environment of farming limit what options a farmer has available to him. Second, because of the industrialization of agriculture and the resulting economic pressures it creates for farmers, the fact that decisions are constrained creates new ethical challenges for farmers. Having fewer options when faced with severe economic pressures is a very different situation for farmers than having many options available. We discuss the implications of constrained choice and show that it increases the likelihood that farmers will consider unethical behavior.

治霾背景下浅层地温能产业规模化发展研究

为了实现治霾目标,国家大力推广可再生能源应用,《关于促进地热能开发利用的指导意见》(国能新能[2013]48号),明确提出将积极推广浅层地温能,扩大其在城镇建筑用能中的比例。我国浅层地温能产业发展面临一系列障碍,为了克服市场调节失灵问题,借助事物发展动力原则,结合全寿命周期理论,依托层次分析法,推导能源发展的核心影响因素,据此提出了浅层地温能产业规模化发展的关键路径,构建了浅层地温能开发利用的长效管理体系。
