With the effect of the human trade doctrine in the international trade field, almost all the countries have paid more attention to the sustainable development of international trade. This article chose the export sustainable development as the research object. On the basis of the analysis of the theoretical connotation of the export sustainable development, this article tried to establish an evaluation indices system and set up an evaluation model of the export sustainable development level, and finally made some empirical research on China. The result indicates that the comprehensive level of the export sustainable development in China showed a tendency to rise from 1985 to 2003 and the export sustainable development level of China in these years can be divided into four grades: excellent, good, moderate and poor. In most years, the social economic benefits of export was obtained at the cost of the deterioration of environment and the depletion of resources, and the economic profit of export did not increase with the enlargement of the export scale because of the deterioration of the terms of trade. Therefore, China should be careful about the problem of poverty accompanied by the increase of export. 相似文献

It is the principal proposition of this paper that formal agricultural research, and its supporting policies and planning, has not responded adequately to the special situation that exists in semi-arid Africa. In many cases the transfer of research approaches based on temperate and more humid tropical experience has contributed to greater instability and the growing environmental crisis. Radically different research structures, objectives, methods and expectations are necessary to contribute to the redevelopment of long term regenerative systems of production that will provide the short and long term needs of the people who live in the semi-arid regions and at the same time protect these environments. 相似文献

Farmers attempting to subsist in tropical uplands often rely upon unsustainable resource use practices that lead to soil erosion, declining crop yields, and a loss of soil productivity capacity. Other uses of tropical uplands, including logging and conversion of forest to rangelands, have similar results. The undesirable effects of these actions are felt on-site, at the watershed level, and even nationally. Ecological cause-effect relationships are poorly understood, and few examples exist of the successful integration of ecological knowledge with upland development. It is hypothesized that recent results of ecological research could be applied to uplands management so that stable sustainable systems of human use may be established. A second hypothesis is that statistically reliable data can be obtained from experiments in upland situations, although natural variations of soils, weather, and vegetation are great. To test these hypotheses, research involving multinational collaboration among American and Southeast Asian scientists has begun. The objective of the work is to provide credible quantitative information to help policy and decision makers and resident farmers to plan and implement improved practices based on ecological principles.Some findings to date include:

1. | Ecological principles are difficult to relate to the practical context of upland agroecosystems. Indeed, the null hypothesis is necessary for planning experiments and demonstrations. |
2. | The signal-to-noise ratio in these field experiments is low, and the detection of changes due to human intervention in soil erosion, nutrient movement, and plant productivity is difficult. |
3. | Obstacles to field research in developing countries include logistic, cultural, political, and institutional factors. It is essential that local land managers participate from the start with scientific researchers in designing experiments. |
4. | Planned collaboration among academic and government scientists facilitates design of relevant research and the implementation of results. |
5. | The idea of ecologically based management has been well received by researchers and government officials in Asia. There is little argument with the logic of the approach. |
6. | Pressures for quick responses to urgent problems in the uplands conflict with the need for careful, long-term, statistically valid scientific research. |
7. | Ecological principles are vaguely understood and poorly articulated in the scientific literature. The transfer and application of ecological science to the developing world would be enhanced by clearer statements of principles. |

Landfills have historically been seen as the ultimate solution for storing waste at minimum cost. It is now a well-known fact that such deposits have related implications such as long-term methane emissions, local pollution concerns, settling issues and limitations on urban development. Landfill mining has been suggested as a strategy to address such problems, and in principle means the excavation, processing, treatment and/or recycling of deposited materials. This study involves a literature review on landfill mining covering a meta-analysis of the main trends, objectives, topics and findings in 39 research papers published during the period 1988-2008. The results show that, so far, landfill mining has primarily been seen as a way to solve traditional management issues related to landfills such as lack of landfill space and local pollution concerns. Although most initiatives have involved some recovery of deposited resources, mainly cover soil and in some cases waste fuel, recycling efforts have often been largely secondary. Typically, simple soil excavation and screening equipment have therefore been applied, often demonstrating moderate performance in obtaining marketable recyclables. Several worldwide changes and recent research findings indicate the emergence of a new perspective on landfills as reservoirs for resource extraction. Although the potential of this approach appears significant, it is argued that facilitating implementation involves a number of research challenges in terms of technology innovation, clarifying the conditions for realization and developing standardized frameworks for evaluating economic and environmental performance from a systems perspective. In order to address these challenges, a combination of applied and theoretical research is required. 相似文献

SUMMARY The sun is the ultimate energy source of the Earth. This energy is a resource if utilised, a menace if not. Plants collect and transform radiant energy to chemical energy through photosynthesis. Part of the converted energy is used for their maintenance, while the remainder is stored as biomass. The living biomass plays a vital role in ecological processes and relationships, and provides essential services: soil and water conservation, a buffer against the adverse effects of rain, wind and sun, aesthetics, recreation, and environmental cleaning. Harvested biomass provides safe energy and materials for production of valuable products through industrial processes and household-based technologies. In the absence of vegetation, solar radiation dries soil moisture and disrupts natural processes essential for healthy ecosystem sustenance. Light-use efficiency of plants is positively correlated with rate of growth and bamboos are among the fastest growing perennial plants. This paper is not a thorough review of radiation or bamboo. The following issues are highlighted: (1) The flow of sunlight to the Earth and its usefulness as a resource if used properly and its tendency to become a nuisance if not. (2) The virtues of bamboos as light interceptors and providers of goods and services, better than many tree species. (3) The endowment of Ethiopia with large natural bamboo resources, the availability of denuded land for expansion, and the urgency for proper management, expansion and utilisation for faster socio-economic development and environmental improvement. 相似文献
