基于构造定量化研究的煤层气勘探区优选——以大宁—吉县地区为例

大宁-吉县地区位于鄂尔多斯盆地东部晋西挠褶带南段,区内主要发育一系列宽缓褶皱,东部、东南部发育少量断层。野外厚层砂岩节理测量点的观测结果表明,区内盖层砂岩节理发育方向为NE30°、NE60°和NW60°,在北部的午城、窑曲、管头一带节理密度较大。运用分形理论对煤层及盖层砂岩显微裂隙进行分析,区内8煤层显微裂隙比5煤层发育,午城、山中、薛关、水堤所围成的区域以及窑曲-桑娥区块分维值多在0.8以上,为显微裂隙发育区。综合分析认为薛关、午城和桑娥区块是煤层气勘查目标区。     

山区公路隧道建设对地下水环境扰动评价研究

由于长大隧道建设期间具有显著地集水廊道效应,施工过程中地下水不断向隧道轴线汇集,进而诱发一系列的水文 地质灾害,给施工人员和隧址区周边的生态环境带来不可估量的损失。为此,在构建山区公路隧道建设对地下水环境扰动 评价体系的基础上,考虑到群决策不同个体实践认知水平的差异,把基于决策人员偏好信息的区间数层次分析模型用于山 区公路隧道建设对地下水的环境影响评价领域,并与模糊综合评判法进行有机结合,对西藏米拉山特长隧道建设对地下水 环境影响进行评价,结果表明,米拉山特长公路隧道建设对地下水的扰动程度属于一般水平。依据评价结果,采取了相 应的工程措施,实现了隧道建设与隧址区环境保护的协调统一,可为类似地区隧道建设的地下水环评工作提供有益的 参考。     

LOCATIONAL PROBLEMS AND PREFERENCES IN PRESCHOOL CHILD CARE*

With the increased use of formal child care, the number of child care alternatives has grown. The locational problems and preferences of University of Connecticut employees who use formal child care for children under age 6 are examined because an on-site program is available as one option. Difficulty finding care at a convenient location is related to residential location. Preference for worksite care decreases with increasing commuting distance. Variations in reported locational preferences by commuting zone are consistent with the notion of locating services within the activity spaces of the users. As commuting distance increases, worksite day care represents a greater displacement from the activity spaces of the child and possibly of other family members.     

Tree planting, local knowledge and species preference in the South Tongu District of Ghana: Some perspectives

This paper explores the link between local knowledge and tree specie preference in the South Tongu District of Ghana. It is based on a field study that observed, inter alia, that even though Neem is not commonly promoted in Ghanaian afforestation programmes, it is highly popular in the area. Local farmers' preferences for tree species are governed by several factors –; suitability to local climate, availability and access to markets, perceived economic value and availability of wood fuel dependent enterprises. The survey further demonstrates that local knowledge is incorporated into decision-making regarding adaptation of farming practices to changing rainfall patterns; and also plays a role in influencing specie preference. Some likely implications, which these may have on conservation policy and planning in the study area, are also explained. This revised version was published online in July 2006 with corrections to the Cover Date.

Tourism development preferences among the residents of Lake Bosomtwe Basin, Ghana

Controversy over the extent to develop tourism in tourist destinations remains unresolved. This paper examines the extent of tourism development residents are prepared to tolerate in the Lake Bosomtwe. A resident survey undertaken during January 2006 in the basin reveals that residents are more oriented to large scale tourism. The major perceived reason for this preference is that large scale tourism development will help provide for the material needs and wants of the basin’s population. It is concluded that residents of Bosomtwe basin equate large inflows of visitors with success and fame, but field observations indicate that the residents will wreck the basin’s environment if tourism development is left in their sole control.

Consumption preferences and environmental externalities: A hedonic analysis of the housing market in Guangzhou

The urban housing market of China has been transformed since the 1980s from a centrally-planned to a free-market system. This study aimed to (1) investigate the position of outdoor environmental quality in house-buyers’ preferences; (2) assess monetary values attributed to environmental externalities by the hedonic pricing method (HPM); and (3) test the applicability of HPM in China. The study area was Guangzhou, the major city of south China with a booming real-estate market. A questionnaire survey was conducted with households in new residences sold in 2004. The main buying motives were improving living quarters and floor area. Security concerns and a preference for high-rise buildings were somewhat unexpected. Good outdoor environment, including green space provision, proximity to parks, and views of green space and water, carried significant hedonic values. Differences between the submarkets of old and new towns were found; new town households expected apartments in high-rise blocks, exclusive residential land use, and views of green space, while old town households preferred proximity to shopping areas and workplaces, green space within the development and proximity to nearby parks. The findings could help to fine tune the developing housing market to match supply with demand in quality terms. Values accorded to environmental attributes could justify funding for urban green spaces and nature conservation. The study verified the applicability of HPM to the housing context in China.     

Communicating Climate Change: Reinforcing Comprehension and Personal Ties to Climate Change Through Maps

Although climate change is highly prevalent in the media, people in Europe and the United States are often unsure about climate change terms, processes, and its personal consequences. In other words, climate change communication seems to be largely failing so far. Among other communication tools, maps are widely used for explanatory purposes by scientists and the media. Here two questions arise: first, whether high map complexity may be too intricate to be understood and discourage people from deciphering the map; and second, whether personal interest in climate change can be influenced by the phenomenon depicted or the map’s scale. In a survey conducted among 109 students in the USA, 63% of respondents preferred a simple map, but a substantial subset, 37%, asked for complexity to receive more information. Regional phenomena evoked more concern than far-off phenomena (concern level index difference of 0.93 on a 5-ranked Likert scale). The advantage of maps showing local areas could not be statistically confirmed.
