Predicting the multiple pathways of plant succession

Classical concepts view succession as a deterministic, mechanistic regeneration of the disturbed community, and thus have limited applicability to fire-prone ecosystems, A recently developed multiple pathway succession model appears to have more realism and applicability in frequently disturbed ecosystems. It includes a set of species-specific attributes that are vital to reproduction and survival, and permits variable succession pathways depending on the stand's age (and thus species composition) when disturbed. Examples from Australia and the northern Rocky Mountains (USA) are presented, as are approaches to refining and improving the model.     

湘鄂赣三省粮食产业及其可持续发展对策

长江中游湘,鄂,赣三省历来是我国粮食主产区,目前是我国南方１５省（市）中主要的三个粮食调出省。该区粮食产业的持续发展,在我国粮食总量平衡和区域平衡的供需格局中具有不可替代的战略地位。随着改革开放和工业化进程向内陆推进,该区粮食产业持续发展具有重要意义。     

世界与中国核电市场寿命周期探索

核电是高效、安全、清洁、经济的能源 ,但它和一切进入市场的产品一样 ,有其市场寿命周期。世界核电发展 5 0年 ,经历了市场寿命的投入期、成长期 ,现在处于成熟期 ;中国核电发展十多年 ,已进入成长期。笔者探索了世界与中国核电市场寿命分期 ,各期产生转换的动因 ,重点探讨了核电市场前景 ;同时认为 ,世界核电在未来的 2 0年左右 ,由于退役装机容量大于新增装机容量 ,可能出现阶段衰退 ,但会继续发展 ,进入新的寿命周期 ;而中国核电由于社会、经济快速发展 ,能源资源的不足 ,能源、电力结构调整与地区优化 ,环境与生态可持续发展等多方因素 ,仍需要不断发展 ,预测中国核电将有 6 0年以上的发展期。     

In search of greener towns

Around 1970 a quiet revolution occurred in several European countries involving the use of naturalistic design approaches and ecological principles in the design and management of urban green spaces. The objective was to bring the qualities of nature into peoples’ daily lives and provide a richer external living environment. Parallel programmes of community participation and environmental education were involved. Successful projects in Holland, Sweden and Britain are described. These indicate that despoiled urban and urban‐fringe land can be quickly and economically transformed into green environments which are attractive for living and commercial investment. A reorganisation of Local Authority landscape resources is recommended.     

Heritage as exemplar: a pedagogical role for heritage studies in values education

Studies of heritage at all levels of education can help foster understanding of other peoples and cultures and of the environmental issues facing us all. Used judicially, such studies have a highly positive role to play in educating people everywhere to contribute to making the world a sustainable and just environment for future generations. They provide examples or case studies, in the pedagogical sense used by educationalists, that illustrate many valuable points that are central to a sound values education contributing to ensuring that the public, and hopefully the political elite, are engaged in a push for such a just and sustainable future. Individual examples of heritage sites, and especially of World Heritage properties, contain valuable lessons of great pedagogical value.

江西德安县地方性氟中毒区生态地球化学研究

江西德安吴山地区地方性氟中毒区域存在高氟的地球化学异常。富氟的岩(矿)石为其原生源,受表生地质作用和人为活动的影响,在土壤、水和生物体中形成了富氟的生态地球化学环境系统。研究发现,该地区氟进入人体主要通过5个途径,其中食物是进入人体最主要途径,食物中的氟元素超标情况严重,其次是通过饮用水进入人体,并根据这些规律提出德安地方性氟中毒病几点防治建议。
