THE CORPORATE INTERVIEW AS A RESEARCH METHOD IN ECONOMIC GEOGRAPHY*

The open-ended corporate interview as a qualitative research method is proposed as a valuable component of an evidentiary strategy in economic geography. It is argued to be more sensitive than other survey methods to historical, institutional, and strategic complexity. The corporate interview method is particularly appropriate in periods of economic and social change that challenge traditional analytical categories and theoretical principles. Some problems inherent to the method, and strategies for minimizing their impact on the research project, are described.     

广东的湿地及其保护

广东湿地资源丰富,湿地类型多,面积大,分布广,密度高,亚热带和热带特色明显,近数十年来,由于对湿地的盲目开垦和不合理改造利用、环境污染、水土流失、对湿地生物资源过度开发等原因,不少湿地已遭受到严重的破坏.湿地具有重要的生态、经济、社会功能,必须采取切实措施保护和合理利用广东的湿地资源.     

MEXICAN URBAN COLONIAS IN THE SALT RIVER VALLEY OF ARIZONA

The history of the Salt River Valley is often characterized as a boomtown narrative that highlights the exploding Anglo population and rapid suburban sprawl that followed World War II. Frequently overlooked is the fundamental role that Mexicans played in the early suburbanization process through the formation of urban colonias, or suburban Mexican settlements. Early Mexican suburbs, despite their rural atmosphere, were connected to the pre–World War II urbanization process in the Salt River Valley. Our research seeks to amend and clarify the urban historical record by documenting the diverse and dispersed array of Mexican suburban settlements, a process generated by industrial agriculture, decentralization, and residential segregation.

德国饮用水水源保护区的建立与保护

在德国,饮用水被确定为生活中的第一物质材料,饮用水水源保护区的建立与保护是一项法律程序。德国人经过１００多年的长期实践,迄今为止已建立近２００００个饮用水水源保护区,在水源地保护方面积累了大量经验,被欧美工业国吸收采纳。本文介绍了德国饮用水水源保护区的政策、规范与模型;保护区的划定原则与方法,以及利用岩石土壤对水污染的过滤净化能力或者水体自然净化功能,分区分级保护和利用水源保护区的实用哲学。本文还描述了全流域生态系统保护与水源保护区的关系,东德与西德水源保护工作的差距。     

RESURGENT MEXICAN PHOENIX*

ABSTRACT. Popular impressions of Phoenix, Arizona perpetuate the notion that this metropolitan area is an overwhelmingly Anglo place. We challenge this assertion and demonstrate that the city has substantial Mexican roots and is presently being shaped by a vibrant, resurgent Mexican population. Employing historical records, surveys, and landscape data, we articulate the Mexican character of early Phoenix and highlight how the revival of Mexican Phoenix has transformed the urban landscape. We then relate how Phoenix's Mexican population is a more nuanced regional subculture formed through both historical and contemporary connections with specific Mexican states. We conclude with a call for greater understanding of the internal heterogeneity of Mexicans in the United States and how this can inform our geographical interpretations of the growing Latinization of American cities.     

香根草在土壤改良和水土保持中的作用

香根草作为一种理想的水土保持植物具有许多优良特性，目前正在热带和亚热带地区广泛推广种植。本文通过盆栽和大田两方面试验观测了香根草在土壤改良和水土保持中的作用。结果表明，种植香根草后可使强酸性土壤的可交换性铝含量下降，并使土壤ｐＨ值、有机质、全氮、速效氮和钾以及总孔隙度等都有不同程度的增加。与对照区相比，香根草区的径流量和土壤侵蚀量分别下降了６０％和９３％，而土壤含水量上升４％～４２％不等。香根草还可较好地改善果园小气候，使果园生态系统内的士温、气温和空气湿度等都朝着有利于果树生长发育的方向变化。

新疆野生动物的保护问题

阐述了新疆物种多样性的特点及脊椎动物的基本组成。1980年以来，新疆陆续建立了20多个自然保护区，其中属于国家级的保护区3～4个。已知的野生脊椎动物种类约700种（隶属于5纲，37目，97科，196属）。包括哺乳类约134种，鸟类392～430种，爬行类40～45种，两栖类6～7种和鱼类93～120种（鱼类中约半数为引入种）。近年来经济利益的驱动下，一些保护区名存实亡，成人人类经济活动最频繁的地方，野生物种的处境日趋恶化。本文企图在动物保护方面提出问题和观点，便于在西部开发的过程中引起决策者们的重视。

WILDLIFE CONSERVATION AND BAMBOO MANAGEMENT IN CHINA'S SOUTHEAST UPLANDS*

ABSTRACT. The subtropical forests, grasslands, and wetlands of Southeast China's Wuyi‐Daiyun Mountain Range provide essential habitats for diverse wildlife, including a dwindling population of tigers. Three primary protected areas, the Meihuashan, Wuyishan, and Longxishan Nature Reserves, contain varied wildlife habitats and also provide natural resources for 7,000 people in several dozen villages. A field‐based study of land use and habitat quality in these reserves shows that anthropogenic bamboo forests are among the least valuable habitats for wildlife but that, as the primary source of household income, bamboo monoculture is spreading rapidly and replacing habitats of greater ecological value. Although authorities in Meihuashan have demarcated the many broadleaf forest patches for strict protection, household income and bamboo‐management research in all three reserves suggests that successful habitat conservation may ultimately depend on more equitable systems of land tenure, improved cooperative cottage industries, and greater local economic diversification.     

KITCHENSPACE,FIESTAS, AND CULTURAL REPRODUCTION IN MEXICAN HOUSE‐LOT GARDENS*

ABSTRACT. The house‐lot garden in central Mexico is gendered space where changing cultural identities are negotiated, re‐created, and celebrated as “tradition” is continually redefined. No clear boundary separates the kitchen from the house‐lot garden or the private space of the household from the semipublic space of the community. During collective food preparation for religious fiestas, gendered reciprocity networks strengthen community relations and foster alliances between traditional neighborhoods and between communities in the region. At the intersection of everyday life and fiestas, food‐preparation spaces, or kitchenspaces, in the house‐lot garden are fertile areas in which to explore the cultural reproduction of nature‐society relations. They are vital to understanding gender, place, and culture in this region and represent people's symbolic connection with the land in increasingly urban contexts. This article analyzes the sense of place that Mexican women derive from their house‐lot gardens.     

HUMBOLDT'S MEXICAN TEXTS AND LANDSCAPES*

ABSTRACT. While in New Spain from 1803 to 1804, Alexander von Humboldt interacted with some of its landscapes and the texts that represented them. Analysis of those interactions regarding the Basin of Mexico and the Gulf lowlands demonstrates what purely text‐based studies of the production of places cannot: The contrasting landscape elements and patterns that had emerged over millennia during precolonial times in those two places, their relative degrees of depopulation during the colonial era, and the relative degrees of rigor Humboldt applied to interacting with the resulting landscapes and the texts that represented them greatly affected his representations of those places in his 1811 Essai politique sur le royaume de la Nouvelle‐Espagne. His representations of the precolonial Basin of Mexico as productively developed and of the precolonial Gulf lowlands as pristine have influenced the transformations of those places in the two centuries after New Spain became the Mexican republic through its wars of independence (1810–1821).     

推广香根草篱作水土保持措施值得重视的几个问题

1988年以来,我国推广香根草蓠作水土保持措施,收到的水土保持效益甚佳,香根草篱的短处有:经济效益欠佳,与作物争水肥,容易发生病虫害。为使香根草蓠扬长避短,提出的意见有:1.宜在秦岭-伏牛山以南海拔<2000米的地区推广;2.人少地多的山区荒坡地上可大力推广;3.建立香根草与经济作物组成的混合蓠;4.加强香根草病虫害防治研究。     

UPLAND AGRICULTURE IN THE MAYA LOWLANDS: ANCIENT MAYA SOIL CONSERVATION IN NORTHWESTERN BELIZE*

ABSTRACT. In the 1970s scholars began to accept Maya terracing as the manifestation of ancient intensive agriculture and large populations. We examine many ancient terraces and berms excavated in the Three Rivers region of Belize, synthesize the geography and suggest the intent of terracing across the Maya Lowlands, and analyze the history of terracing and soil erosion. Terraces occur in several slope positions and diverted and slowed runoff, to build up planting surfaces that could maximize soil moisture. The first accelerated soil erosion occurred during the Preclassic period (1500 b.c. ‐a.d. 250). Maya terracing started in the Early Classic period (a.d. 250–600) and spread across the Lowlands with the great population expansion of the Late/Terminal Classic period (a.d. 600–900). Thereafter, the Maya would largely forsake terracing. Though abandoned for a millennium, many terraces still function in today's tropical forests and burning milpas.
