国内外耕地保护的经济补偿研究进展述评

采用文献回顾法、归纳法和比较研究法对国内外耕地保护经济补偿研究的趋势、理论和方法、内容和体系进行了归纳、分析和总结。研究表明:①在研究内容方面,国外将耕地保护的经济补偿融合于农业补贴,尤其是农业生态补贴和农业环保计划之中。国内耕地保护经济补偿研究内容则多侧重于对耕地价值、价格和效益的内涵界定、测算方法以及耕地非农化补偿(征地补偿)研究方面。②在研究体系方面,已有研究未能将区内和区际补偿、生态效益和社会效益补偿进行有机结合。③在研究理论和方法方面,未能将相关理论进行有机融合,也未能从耕地保护外部效益供体与受体分析的基础上合理测算耕地保护的外部性。为此,我国学者应在借鉴已有研究成果的基础上,结合我国实际,构建适合我国国情的的耕地保护经济补偿体系和运行机制。     

关于修改我国《环境保护法》的若干思考

Predicting the Impacts of Future Sea-Level Rise on an Endangered Lagomorph

Human-induced global climate change presents a unique and difficult challenge to the conservation of biodiversity. Despite increasing attention on global climate change, few studies have assessed the projected impacts of sea-level rise to threatened and endangered species. Therefore, we estimated the impacts of rising sea levels on the endangered Lower Keys marsh rabbit (Sylvilagus palustris hefneri) across its geographic distribution under scenarios of current conditions, low (0.3-m), medium (0.6-m), and high (0.9-m) sea-level rise. We also investigated the impacts of allowing vegetation to migrate upslope and not allowing migration and of two land-use planning decisions (protection and abandonment of human-dominated areas). Not surprisingly, under all simulations we found a general trend of decreasing total potential LKMR habitat with increasing sea-level rise. Not allowing migration and protecting human-dominated areas both tended to decrease potential LKMR habitat compared with allowing migration and abandoning human-dominated areas. In conclusion, conservation strategies at multiple scales need to be implemented in order to reduce the impact of global climate change on biodiversity and endangered species. At the regional level, managers must consider land-use planning needs that take into account the needs of both humans and biodiversity. Finally, at the local scale those agencies that are in charge of endangered species conservation and ecosystem management need to rethink static approaches to conservation or else stand by and watch ecosystems degrade and species go extinct. This can be accomplished by bioclimatic reserve systems where climatically underrepresented areas are included in conservation planning along with the standard concerns of threat, opportunity, connectivity, and viability.

Environmental impact assessment in the People's Republic of China: a case study of the Shanghai Second Sewerage Project

In March 1994, China announced its plans for sustainable development in a White Paper entitled 'China's Strategy for Population, Environment and Development in the 21st Century. To achieve the objective of sustainable development; economic, social and environmental aims have to be consistent with each other and meet the needs of the present, without compromising the ability of future generations to meet their own needs. Sustainable development, therefore, encompasses many 'ideals, which need to be introduced through practical management techniques. This paper addresses the role that EIA could play in promoting sustainable development projects in the People's Republic of China by way of the detailed examination of a case study—the Shanghai Second Sewerage Project.     

The Tribal Environment: Solid Waste in Indian Country

The issue of solid waste management in Indian country is multidimensional in scope because it affects more than just regulatory concerns. There are more than 550 federally recognized Alaska Native and American Indian Tribes in the United States. Tribes are sovereign nations that have a special relationship to the federal government and a unique legal status. The environmental problems faced by tribes are many, and it is only fair that tribes, as sovereigns, specify the levels of protection on their lands. The one-size-fits-all regulatory approach to environmental problems and solid waste management in particular does not work and often leads to conflict between tribes and the federal and state governments. Inherent tensions also exist between tribes and various levels of government concerning jurisdiction of lands and managing solid waste. These intergovernmental relationships are often complex and present unique challenges to all. More research needs to be done on targeting resources to meet the capacity-building needs of tribes, as well as the overall environmental management needs of Indian country under the federal trust obligation. Successful intergovernmental relationships can be fostered through partnership arrangements between tribes and federal, state, and local governments. In the area of solid waste such partnerships have worked. It requires that all levels of government deal with tribes with careful consideration of their cultural, historic, and socioeconomic aspects, which are often intertwined.     

Development aid: The moral obligation to innovation

The prominent, though not exclusive, role of basic needs strategies to attain ethically acceptable development goals raises the question of the ability of development agencies to find and employ basic needs strategies. The obligation to prevent severe human suffering leads to the obligation to employ basic needs strategies to attain basic needs goals. The history of failure by development agencies in finding and employing basic needs tools leads to a further obligation to cultivate bureaucratic environments which foster profound innovation. This requires not only new tools but also new bureaucratic behaviour. An understandable obstacle to simultaneously technological and bureaucratic innovation lies in the tension between responsible behaviour and behaviour promoting fundamental change. Since this tension is based on the unpredictability of creative change, a series of axioms and corollaries which reduce the unpredictability is given. They include: (1) an obligation to seek innovation; (2) a clear statement of basic needs goals and intent to use some basic needs tools; (3) increase in effective knowledge of the poor and their survival strategies; (4) bureaucratic learning flexibility; (5) participatory development and allied emphasis on sustainable resource technologies. The embodiment of these in the learning process approach is illustrated.

含油污泥热解的影响因素初探＊

以含油污泥"无害化"为目的,考察了温度、升温速率及含水率对热解反应效果的影响。实验结果表明:温度越高,热解剩余残渣率和残渣含油率越低,热解产气率越高;含油污泥中有机质发生热解反应的主要温度为350～500℃和575～625℃,若热解残渣含油率控制在3.0‰以下,热解温度选择600℃较为适宜;升温速率对热解产气率、剩余残渣率和残渣含油率基本无影响,但升温速率越快,热解反应的产气量曲线峰越向前迁移,热解反应的时间缩短;含油污泥含水率越低,则热解产气率及残渣率越高,但含水率对残渣含油率和热解反应时间无影响。     

Influence of data preprocessing on the quantitative determination of nutrient content in poultry manure by near infrared spectroscopy

With increasing concern over potential polltion from farm wastes, there is a need for rapid and robust methods that can analyze livestock manure nutrient content. The near infrared spectroscopy (NIRS) method was used to determine nutrient content in diverse poultry manure samples (n=91). Various standard preprocessing methods (derivatives, multiplicative scatter correction, Savitsky-Golay smoothing, and standard normal variate) were applied to reduce data systemic noise. In addition, a new preprocessing method known as direct orthogonal signal correction (DOSC) was tested. Calibration models for ammonium nitrogen, total potassium, total nitrogen, and total phosphorus were developed with the partial least squares (PLS) method. The results showed that all the preprocessed data improved prediction results compared with the non-preprocessing method. Compared with the other preprocessing methods, the DOSC method gave the best results. The DOSC method achieved moderately successful prediction for ammonium nitrogen, total nitrogen, and total phosphorus. However, all preprocessing methods did not provide reliable prediction for total potassium. This indicates the DOSC method, especially combined with other preprocessing methods, needs further study to allow a more complete predictive analysis of manure nutrient content.
