山区生态县区域协调发展的机制构建--以粤北始兴县为例

区域协调机制在不同类型地域和一种类型地域的不同的发展阶段是不同的。始兴县作为一个典型的山区生态县,工业进入加速发展时期,在此经济发展阶段的区域协调问题主要表现在:与外部区域经济、社会发展差距拉大,工业化与流域生态环境保护的矛盾已开始凸现,县政府协调区域发展的财政能力较低,区域协调机制不健全等。由此对始兴县的区域协调机制进行建构:建立健全多层次的区域协调机构;加大纵向和横向政府财政转移支付的力度;加强与相邻相关地区的协调;实施区域空间管治协调,保护城乡生态环境;科学合理选择产业,大力发展循环经济;全县推行绿色GDP考核等。     

论我国东部第三纪含油气盆地是否存在海侵海漫海啸

本文以沟鞭藻生态为基础,结合我国东部第三纪盆地的地球化学、古生物、岩相古地理、区域地质和全球海平面变化,论证东部含油气盆地在第三纪时不存在海水侵进。出现有"海相"沟鞭藻、有孔虫和钙质超微化石是由于当时湖泊咸化及富养料造成的。同时认为沟鞭藻是广盐性生物,其最适应于半咸水环境。     

新疆鸟类新纪录——白腹鹞(Circus spilonotus)

白腹鹞(Circus spilonotus)又叫东方泽鵟,在阿勒泰地区布尔津县(47°46'N, 86°49'E)有多次记录,现确定为新疆新纪录种(或亚种)。但是,在2015年5~7月繁殖期观察,发现它可能与雌性白头鹞(Circus aeruginosus)杂交。两者无论是在形态与行为,还是在地理分布隔离方面,都存在疑团,其分类地位值得商榷。     

Shifting production/shifting consumption: A political ecology of health perceptions in Kumaon,India

Despite rapid economic growth, India has not seen the improvements in food and nutritional security that other developing countries have had. This “Asian enigma” has generated a wealth of economistic analyses seeking to explain the persistence of poor nutrition, yet few studies have looked at everyday experiences of changing food systems, and how this impacts nutritional practices as well as the processes of subject formation. In this paper, I draw on qualitative research conducted in Uttarakhand, North India and examine how state-led shifts in agricultural production have resulted in changing food consumption practices and diminished perceptions of health. Villagers link this decreased health to increased chemicals in home-produced food, greater dependence on the market for food purchases, and generational changes in dietary preferences. Despite villagers’ cognizance of the negative health effects of these practices, they largely view these byproducts of capitalistic development with an air of inevitability. Following Mansfield (2011) this paper contributes to the political ecology of health literature by employing the concept of food as a “vector of intercorporeality” (Stassart and Whatmore, 2003:449) and bringing this into conversation with a poststructuralist understanding of subjectivity. I argue that within shifting landscapes of agriculture production and food consumption, notions of diminished health are indicative of the complex and always incomplete processes of subject formation. I view shifting health perceptions as intimate bodily resistances to agricultural development, and conclude that within agricultural development programs a focus on bodily health and well-being is a fecund platform for further experimental research that seeks to imagine development differently.

RETHINKING CULTURAL ADAPTATION*

Several issues surrounding the concept of cultural adaptation and its significance to cultural geography are discussed. A new model of cultural adaptation is developed to explain the evolution of spatial structures. Also a research agenda for geographic inquiry is proposed.     

Karyological and Ecological Evolution of the Monocelididae (Platyhelminthes, Proseriata)

Abstract. The karyology and ecology of 76 species of Monocelididae arc discussed. Species with a basic karyotype are mainly limited to low dynamic subtidal areas: this is considered to be the ancestral habitat of the group. From there, parallel evolution resulted in colonization of more stressed environments. In all lineages, the colonization of new environments is correlated with karyotype rearrangements such as translocations and Robertsonian mechanisms of fusion and fission.     

A Landscape Guide in Environmental Education

Abstract

The interpretation of landscapes is an important way to learn about geography in environmental education. A Landscape Guide to the Bachelor Reserve applies geographic/historical and biological/ecological perspectives to the interpretation of ten landscape scenes along a three-mile walking tour. For each scene, the guide describes the environmental setting, the composition and structure of the vegetation, and the history of human influences. Questionnaire and field assessments document a well-received interpretive tool, and the need to guide participants across land transitions and interpret land use history clearly. Landscape guides can be used in school/community land labs and contribute to holistic learning and multidisci-plinary exercises in formal and informal environmental education programs.     

Contextualizing other political ecologies: Japan's environmental aid to the Philippines

This paper argues for the utility of a focus on contextualized sources of environmental change to address the ever more diverse contexts of political ecology. In order to overcome the conventional approach to contextual sources that has tended to be analytically one‐dimensional and limited, I seek to provide a more nuanced account, notably by examining the neglected case of green aid of a nonwestern aid donor, Japan. Using conceptual tools that are both conjuncture‐based and multiscalar, the paper examines the way in which a post‐Rio international policy drive to promote so called green aid during the 1990s was translated into and conditioned by the historically and geographically specific contexts of Japan and the aid recipient featured herein, the Philippines. This focus on contextual sources helps to elucidate (i) how the ambiguous nature of international aid criteria combined together with Japan's own domestic political economy to render problematic an ostensibly environmental project, (ii) the manner in which neoliberal economic restructuring was translated into one of Japan's key policy initiatives in the 1990s and formed the backdrop to the specific aid case project discussed here, (iii) how Japan's environmental aid process in the Philippines was shaped through a repoliticization of various green discourses, and (iv) how the complex dynamics among stakeholders ended up compromising the very nature of the case study project.
