本文从分析物质结构、物质运动形式的角度出发,以大量实例的考察和分析为基础,正确应用对立统一的矛盾法则,提出并论证了物质结构边界层这一新的、严格的环境定义。事物的本质属性及其运动功能是决定事物间相互关系的两项基本条件,物质结构边界层是事物间相互关系的普遍机制。本文以这种观点对构成地球环境的诸要素进行了鉴别,指出了实际存在于客观物质世界之中并分别反映其本质特征和功能特性的实体,即质体与功能体,指出并区别两种不同性质的关系,即中心与环境的关系和功能关系。文中最后以这种新的环境定义,以质体、功能体的新概念对环境科学、生态学的研究对象、属性、方法论等基本问题进行了初步的探讨和论述。  相似文献

固体废物污染与其它环境污染不同,具有综合性、长期性和潜在性。固体废物管理更为强调综合利用和全过程管理,必须通过立法建立科学完善的法律制度来加强固体废物的管理。有关固体废物污染防治的法律、法规、部门规章、地方法规和环境技术标准构成了固体废物法规体系的基本框架。在系统分析现有固体废物法规中存在的问题的基础上,对固体废物管理的法规框架进行了探讨。通过立法,以“统一协调,分工负责”的原则规范各部门对固体废物的管理职能。还强调通过立法、健全监督机制、从法律上限制个人对行政权的滥用、制订技术政策与环境技术标准。除了行政责任外,论文还着重强调了环境违法者的民事责任和刑事责任。  相似文献

Pursuit of economic gain has sponsored much of our planet’s despoliation. Yet conservation increasingly operates as an economic sector that markets biodiversity, ecosystems, and nature as natural capital, service provider, or option value. This essay first elucidates what basic moral theory says about the principle that the goodness of biodiversity and nature is largely economic. It explains why economic valuations may be morally unimportant, inapt for environmental goods, and subversive of more important ideals. It also shows why neither econometric notions of option value nor Daniel Faith’s qualitative one credibly applies. The essay then turns to what an economic conception of goodness implies for conservation practice. It refers to two prominent conservation organizations, whose conservation principles match the market-based ones of the World Business Council on Sustainable Development’s. The environmental record of the latter organization’s practices according to these principles predicts what their adoption for conservation entails.  相似文献

Greening China Naturally   总被引:2,自引:0,他引:2

China leads the world in afforestation, and is one of the few countries whose forested area is increasing. However, this massive "greening" effort has been less effective than expected; afforestation has sometimes produced unintended environmental, ecological, and socioeconomic consequences, and has failed to achieve the desired ecological benefits. Where afforestation has succeeded, the approach was tailored to local environmental conditions. Using the right plant species or species composition for the site and considering alternatives such as grassland restoration have been important success factors. To expand this success, government policy should shift from a forest-based approach to a results-based approach. In addition, long-term monitoring must be implemented to provide the data needed to develop a cost-effective, scientifically informed restoration policy.  相似文献

Nature can survive without humans, but humans cannot survive without nature. Despite a clear understanding of this dependency, humans continue to exist in disharmony with nature, and our current environmental and human dilemmas reflect old problems with a long history. Societies have historically experienced many transitions from harmony between nature and society to a crisis of disharmony, followed by a subsequent transition from crisis to harmony. Such ecological crises arise when society no longer practices sustainable consumption of resources within the limits imposed by the environmental carrying capacity. Over the long term, the growth in human desires has always exceeded the growth in the environmental carrying capacity. Science, technology, and social institutions must all be improved to resolve the ecological crises that arise from this imbalance. This paper discusses how increasing understanding of the problem by the public and by decision makers is the key to minimizing the undesirable impacts of the coming bottleneck for sustainable development. Furthermore, we emphasize how this awareness must be translated into fundamental political and economic changes.  相似文献

Traditional approaches to ecosystem restoration have considered afforestation to be an important tool. To alleviate land degradation in China, the Chinese government has therefore invested huge amounts of money in planting trees. However, the results of more than half a century of large-scale afforestation in arid and semi-arid China have shown that when the trees are not adapted to the local environment, the policy does not improve the environment, and may instead increase environmental degradation. When precipitation is lower than potential evaporation, surface soil moisture typically cannot sustain forest vegetation, and shrubs or steppe species replace the forest to form a sustainable natural ecosystem that exists in a stable equilibrium with the available water supply. The climate of much of northwestern China appears to be unsuitable for afforestation owing to the extremely low rainfall. Although some small-scale or short-term afforestation efforts have succeeded in this region, many of the resulting forests have died or degraded over longer periods, so policymakers must understand that these small-scale or short-term results do not support an inflexible policy of large-scale afforestation throughout arid and semi-arid northwestern China. Rather than focusing solely on afforestation, it would be more effective to attempt to recreate natural ecosystems that are better adapted to local environments and that thus provide a better chance of sustainable, long-term rehabilitation.  相似文献
