Evolutionary stasis, or the long-term (over hundreds of thousands or even millions of years) existence of species in a phenotypically unchanging state, is conditioned by a counterbalance of directional selection vectors acting in opposition to one another. Fluctuations of living conditions for a species, leading to partial and often reversible disturbances of the counterbalance, lead to the development of redundant functional capacities of organisms. This redundancy determines the boundaries of the fundamental species niche and allows the realized niches of populations to change their spatiotemporal location within these boundaries without disturbing the counterbalance. 相似文献

以雎水煤矿水泥厂技改为例,分别对新、老生产线粉尘污染进行了预测和调查监测。用无组织和有组织源强,计算了技改后的粉尘削减量,求得直接效益及环保投资回收期,并试用人力资本法、市场价值法,概算了间接效益。最后对无组织源强确定法作了讨论。 相似文献

通过构建新型城市化和生态环境指标体系,综合运用熵权法和协调发展度模型,比较分析2004~2013年中部地区6个省会城市新型城市化和生态环境的协调发展状况。结果发现:10年期间,6市的新型城市化与生态环境的发展水平及二者的协调发展度都呈现整体上升趋势;武汉市的协调发展水平在总体上处于首位,是中部6省会唯一的协调发展类城市,而其余5市的协调发展水平整体偏低。实现新型城市化与生态环境的协调发展,重点在于保持新型城市化的健康良性发展趋势,同时还应提高生态环境水平,减少生态环境压力,增强环境治理强度,以保证生态环境可持续发展。 相似文献

Agenda 21 requires that countries adopt ‘national sustainable development strategies’ (NSDS), and this has been emphasized in several international commitments. Ghana has contributed to the methodology for peer review of such national strategies, as well as to guidelines designed by OECD and the United Nations for the NSDS process. Ghana has also adopted mechanisms to manage its own development planning in a sustainable manner. This article highlights various types of frameworks for sustainable development currently operating in Ghana, and considers to what extent they conform to NSDS principles. The article concludes that Ghana has made progress in several ways, but faces some of the same challenges as other countries in adhering to sustainability principles. The article offers recommendations as to how Ghana can achieve sustainable development. The article is an independent assessment by the author, who has also formulated most of the recommendations, except where otherwise indicated. 相似文献
