煤矿区居民的环境污染感知——以陕西省韩城矿区为例 总被引:2,自引:0,他引:2
选择陕西省韩城矿区的下峪口矿和燎原矿为研究区域,通过实地访谈和454份有效问卷,利用秩和检验等统计方法,探讨了居民对环境污染的感知的影响因素。主要结论是:(1)矿区居民对环境普遍不满意,他们认为最严重的环境污染是大气污染,其次是噪音污染。矿区环境污染的最主要原因是煤炭加工(洗选、炼焦),采煤并不是最主要的环境污染原因。(2)在居民属性与环境污染感知方面发现:性别对环境污染的感知无明显的影响。年龄和居住时间对大气污染、水污染和噪音污染的感知有显著正向影响。文化程度对水污染、噪音污染和环境卫生感知有显著负向影响,这与文化集团性有关。居住空间对水污染和噪音污染有显著负向影响,说明水污染和噪音污染感知表现出空间层次性。研究结果可以为矿区的环境治理、政策制定等提供参考。 相似文献

The nineties will go down in Italian history as the decade of great political change. By way of emphasising this change, the media and politicians use the expressions `Prima Repubblica' and `Seconda Repubblica' (first and second republics), adopting the terminology used by the French for their `republics'. During the so-called First Republic (1948–1994), the centrist Christian Democrat Party represented the moderate political force in every government. However, the corruption trials of 1992–1993, which involved many of this party's members, led to its collapse at the ballot box. In northern Italy, a consequence of the demise of the Christian Democrats was the resounding success of the Lega Nord at the local government elections of 1993 and the general election of 1994. The Lega Nord based, and continues to base, its success on the use of ethno-nationalist slogans and catchcries. Italy has an ancient tradition – dating at least from the fall of the Roman Empire – of political and linguistic splintering. Given today's situation, this factor may have impacts at the level of the structure of the state: federalism, special statutes for regions and/or provinces, the decentralization of the state, and so on. For the first time for perhaps more than a century, in this new period of uncertain political change, Italians are increasingly viewing territory and its characteristics as politically relevant. Justifications for `national' cohesion are being rediscovered, or invented, at the local level, transforming it into political claims. Italians have begun to talk about relationships with territories and neighbouring groups from a different perspective. At present, traditional political parties and politicians are too slow and insufficiently focused in their response to the rising call for autonomy and decision-making authority at the local level. This factor has provided the time and space for isolationist and culturally self-reliant localist ideologies to propagate. It is impossible to say how long this period of transition will last and what its outcomes will be. The three main choices now facing Italians would be appear to be:(1) reclaim the nationalist sentiment of a united state (abandoned after the Fascist era);(2) provide the space (ideological and territorial) for the numerous localist nationalisms;(3) construct a real and flexible `localist' democracy for Italy as a whole. 相似文献

ABSTRACT. This article examines the geographical ideology of al‐Qa'ida. The central questions are to what extent al‐Qa'ida terrorism is motivated by a desire to control geographical space, and how the organization defines that space as place in its communiqués. The study also asks whether al‐Qa'ida's geographical rhetoric reveals the nature or locations of future attacks. Principal sources are statements and interviews by and with al‐Qa'ida leaders. al‐Qa'ida classifies distinctive geographical realms of legitimization, preparation, and action. Its geographical concerns and ambitions are hierarchical and based principally on perceptions of sacred space. The holy places of Mecca, Medina, and Jerusalem are the cornerstones of a greater Islamic holy land that al‐Qa'ida seeks to rid of non‐Islamic‐especially U.S. and “Zionist”‐elements and replace with a new caliphate. Terrorism directed principally against American civilians in the United States is one of the main tactics by which al‐Qa'ida says it hopes to achieve its goals in geographical space. 相似文献

The article examines how heads of farmers’ households perceive the socioeconomic benefits of Lake Ziway (Ethiopia), the causes of its current degradation, and the state of land and water use management in its watershed. The investigation was based on in-depth empirical field work including a survey with 635 heads of smallholder farmers’ households via interview using semi-structured questionnaires. Further, water abstraction was estimated from three districts that border with the lake. Respondents believe that Lake Ziway provides a number of individual and collective benefits for local communities, private companies and public institution. They stated, however, that the lake is under pressure from the floriculture industry and other investment projects, high population growth and subsequent expansion of settlements and irrigation farms, high applications of agrochemicals, soil erosion, uncontrolled water abstraction, and deforestation in the watershed. The respondents further believe that these activities are degrading the lake water quality, shrinking its water volume and decreasing its fish population. After examining government’s efforts to address these activities, the majority of respondents believe that the government role in the whole watershed is weak. This study contributes to better understand the local socio-ecological coherences and the problems Lake Ziway and its watershed are facing. It also provides information regarding long-term sustainable land and water use planning strategies for the lake and management of its watershed, which could also be applied to other lakes in Ethiopia, and beyond. 相似文献

Homestay tourism has begun to flourish throughout the country, becoming a model of tourism innovation and upgrading, and attracting increasing amounts of capital. Through the collection and analysis of tourist questionnaire data for key cities in the Yangtze River Delta, and based on the theory of tourists' perceived value,18 factors related to the perception of homestay tourism are examined. Through exploratory factor analysis, three main factors of facilities and environment perception, cultural experience perception and service value perception are extracted. Then, from the perspectives of each of these perceptions, this study determines the degree of support for homestay tourism development in the Yangtze River Delta, obtains the key factors that affect the development of homestay tourism, and constructs a structural equation model of tourist perception and the degree of homestay tourism support. By calculating the regression path of the structural equation, the standardized path coefficients of the facilities and environment perception, cultural experience perception and service value perception are found to be 0.724, 0.813 and 0.692, respectively. These three factors have a significant impact on the development of homestay tourism agglomeration. Positive facilities and environmental perception can effectively support the development of homestay tourism, while the cultural experience perception provides its basic condition, and the service value perception constitutes an important factor of homestay tourism development. To better guide the development of homestay tourism, attention must be paid to developing the tourism facilities and environment, to cultivating tourism cultural experiences, and to improving of tourism service value. 相似文献
