中国产品生命周期影响评价方法研究

讨论了确定中国产品生命周期影响评价所需的标准化基准和权重的确定方法和程序，包括产品系统环境影响潜值计算，数据标准化，加权评估 以及计算环境影响负荷和资源耗竭系数4个步骤。标准化基准采用1990年中国人均环境影响总潜值来表达，而权重采用1990年的基准与2000年中国政府的削减目标所估算的基准之间的比值计算。     

生态农业发展与小城镇建设

以3家生态村为例说明乡镇企业在生态农业产值中占据主导地位。通过对乡镇企业的经济效益、环境效益和社会效益以及小城镇发展的优越性分析可知，乡镇企业不宜在农村发展，应该在小城镇中发展，农村生态建设要立足农业，通过减少土地的人口承载量，提高劳动生产率和增加农民收入。     

Relation between some variations of soil and surface vegetatio and desertization in agriculture-pasture interlacing zone an example from Kangbao County,North Hebei,China

The studied agriculture-pasture interlacing zone has its specific natural conditions,at which the natural systems are unstable ,their self-regulation capability is low and the equilibrium is easily broken, and hence the habitat is fairly vulnerable.During last 20 years the increasing population and livestock ,over-reclamation,over-pasturing,over-deforesting, and other intensified negative human activities in the zone resulted in coarsening of surface soil,decrease of organic mater content in soil, reduction of vegetation coverage ,variation and degradation of flora structure, and hence in desertization of the land, although average of gales and sandstorms some decreased and the climate tended to be better in the region.However, the frequent sandstorms occurring in the springs of last and present years has attracted much attention.Investigations confirmed that the main cause for the phenomena is the unreasonable human activites rater than the natural factors.     

Landscape structure and land uese on county level in northeastern Yunnan Province of China—a case study of Huize County

Taking Huize County as an example, the paper analyzed the landscape structure(landscape element structure, landscape type structure, landscape spatial structure, landscape succession structure) and the relations between landscape structure and land use. It was pointed out that the agriculture should be developed in harmony with the landscape structure in the study area.

Scale,context, and decision making in agricultural adaptation to climate variability and change

This work presents a framework for viewing agricultural adaptation, emphasizing the multiple spatial and temporal scales on which individuals and institutions process information on changes in their environment. The framework is offered as a means to gain perspective on the role of climate variability and change in agricultural adaptation, and developed for a case study of Australian agriculture. To study adaptation issues at the scale of individual farms we developed a simple modelling framework. The model highlights the decision making element of adaptation in light of uncertainty, and underscores the importance of decision information related to climate variability. Model results show that the assumption of perfect information for farmers systematically overpredicts adaptive performance. The results also suggest that farmers who make tactical planting decisions on the basis of historical climate information are outperformed by those who use even moderately successful seasonal forecast information. Analysis at continental scales highlights the prominent role of the decline in economic operating conditions on Australian agriculture. Examples from segments of the agricultural industry in Australia are given to illustrate the importance of appropriate scale attribution in adapting to environmental changes. In particular, adaptations oriented toward short time scale changes in the farming environment (droughts, market fluctuations) can be limited in their efficacy by constraints imposed by broad changes in the soil/water base and economic environment occuring over longer time scales. The case study also makes the point that adaptation must be defined in reference to some goal, which is ultimately a social and political exercise. Overall, this study highlights the importance of allowing more complexity (limited information, risk aversion, cross-scale interactions, mis-attribution of cause and effect, background context, identification of goals) in representing adaptation processes in climate change studies.
