生态农业建设规划研究--以大连市旅顺口区为例

旅顺口区是大连市的重要组成部分,该区农业主要由以经济作物为主的种植业和畜牧业以及水产业构成.目前总体上具备了实现农业现代化的基础和条件.然而,土地垦殖率与农业利用率低、水资源缺乏等问题制约该区生态农业的发展.在此首先介绍了生态农业的概念、内涵及生态农业建设的主要内容,运用生态学及生态经济学原理,规划旅顺口区农业以生态农业、观光农业和效益农业为主体的现代农业,并进一步提出旅顺口区未来生态农业建设的重点项目及实现生态农业建设的保障措施.

论长江上游水土保持与农业持续发展

长江上游广大山丘区社会发展的历史证明：水土流失严重破坏了人类赖以生存的水土资源，影响了当地农业生产的发展。从１９８９年开展实施的长江上游水土保持重点防治工程，６年来以其显著的经济、生态和社会效益说明：水土保持不仅控制土壤侵蚀，改善生态环境，而且维护了自然资源的永续利用，成为支持长江上游山丘区农业持续发展的重要基础工程。     

Maize: The Native North American’s Legacy of Cultural Diversity and Biodiversity

Recent research has focused on establishing the values of preserving biodiversity both in agriculture and in less managed ecosystems, and in showing the importance of the role of cultural diversity in preserving biodiversity in food production systems. A study of the philosophy embedded in cultural systems can reveal the importance of the technological information for preserving genetic biodiversity contained in such systems and can be used to support arguments for the protection/preservation of cultural diversity. For example, corn or maize can serve as a paradigm of Native American thinking and can provide one of the few areas from which common philosophical conceptions can emerge. An examination of the cultivation of corn or maize as an agricultural activity and as a cultural activity in Native American literature reveals a philosophy that recognizes the importance of biodiversity and provides techniques for its preservation. Corn, and the food and the materials derived from it, is something thought out, not by specialists, but by the entire tribe and its ancestors, even if this thinking is done within what we might consider a framework of highly mythical notions. Importantly, this framework yields an understanding of both the genetics and nutrition of corn. A survey of these mythical notions (myths and stories) and agricultural practices makes this thought explicit and exemplifies the value of cultural diversity and biodiversity.     

中国农业资源的可持续性分析

本文以农业资源可持续利用的三项基本约束条件为前提,从广义上（时间上的可持续约束、空间上的可持续约束、资源管理上的可持续约束）和狭义上（粮食增长速率和人口增长速率的同调对应）对于中国农业可持续发展与农业资源可持续利用,作了理论上的分析和实际上的计算。并将中同从１９５２～１９９５年划为８个时段,分别作了可持续发展分析并寻求其背景原因,作出了相应的农业可持续发展模型。最后,对于未来中国农业可持续发展的战略提出了基本的监控指标。

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.
