场地地下水腐蚀性评价,是岩土工程勘察重要的工作内容。在评价过程中,若不考虑水文地质单元及上部功能分区的影响,仅以某一区域的分析结果代表整个场地,可能会造成整体的评价结果偏高或偏低,导致后续基础设计工程量的浪费,或带来安全隐... 场地地下水腐蚀性评价,是岩土工程勘察重要的工作内容。在评价过程中,若不考虑水文地质单元及上部功能分区的影响,仅以某一区域的分析结果代表整个场地,可能会造成整体的评价结果偏高或偏低,导致后续基础设计工程量的浪费,或带来安全隐患。因此,有必要根据场地水文地质特点进行分区调查与评价。以南方某核电厂厂前区地下水腐蚀性评价为例,采用分区调查法对不同区域进行评价,结果显示,不仅可规避安全风险,且能指导设计优化,为后续的基础防腐设计提供具有针对性的设计参数。 展开更多

This article explores the relationship between the tourist's cognition of the landscape experience and the environmental conservation efforts at three distinct tourist sites in mountains of southwestern China. A total of 1500 on-site questionnaire surveys were distributed and 1142 valid questionnaires were used for statistical analysis. Results from multi-group path analysis showed that both cognition of the cultural landscape experience and cognition of the natural landscape experience had positive impacts on environmental conservation behaviors and behavior intentions of tourists. Results from comparative analysis among the three tourist sites indicated that cognition of the cultural landscape experience had a stronger power to predict senior environmental conservation behaviors and behavior intentions than cognition of the natural landscape experience, whereas cognition of the natural landscape experience had more power to predict general environmental conservation behaviors and behavior intentions than cognition of the cultural landscape experience. Furthermore, our findings benefit environmental management and sustainabilityat tourist sites. 展开更多

This article describes the investigation of hazardous waste (HW) in the Three Gorges Area of Chongqing region, which indicates that by May 2002, the dumped HW therein amounted to 14 600 t and was mainly distributed in five districts and counties with 11 000 t in Fuling, 1 650 t in Fengdu, 950 t in Wanzhou; 630 t in Wushan and 430 t in Yunyang. The total amount was composed of 9 670 t chromic residue, 2 310 t waste oil and residue, 410 t waste (false) fertilizer, 28 t waste chemical medicine, 26 t waste materials and 2 200 t other things including acid residue, waste asbestos, fluorine silicate, pigment, additive, waste acid, alkali, nitric acid, vitriol, lead mud, storage battery, calcium carbide, potassium cyanide, polluted soil, discard dynamite, waste packing barrel of cyanides, etc. In all of the HW, 578 t can be treated by chemical neutralization and stabilization technology such as redox, chemical precipitation, acid and alkali neutralization, etc., and the rest is temporarily untreatble and should be removed and piled at a temporary storage site above the 177 m water level of the dam with an aim to be transported to a future disposal site for innocuous treatment. 展开更多

The purpose of this study was to consider the relevance of CARICOM's existence to the Virgin Islands (BVI). Its relevance becomes more significant to the BVI and the Caribbean, by extension, when the globalization phenomenon is applied; a phenomenon that has been in existence for centuries. Overall, the study concluded that even though the BVI remains only an associate member of CARICOM and not of CSME, it still has an interest in the progress of the regional grouping and its trade initiatives. Over the years, CARICOM has been struggling with its identity as a unified grouping. Nonetheless, it was found that in an effort to combat the trade liberalization process, the grouping must find that inner connection to advance its agenda on the global stage. Accordingly, it has been suggested that CARICOM begin to focus on its strengths and opportunities in order for economic development across the region to occur. It has also been recommended that more serious considerations be taken towards the development of a comprehensive regional market for the trading of goods and services, that is, the Caribbean Single Market and Economy (CSME). To substantiate its findings, the paper used the qualitative research approach, combined with a situation (SWOT) analysis. 展开更多

In this research,the Factor Analysis model of measuring provincial low carbon development in China has been constructed.Based on data from 30 provinces,an empirical study was developed to measure comprehensive low carbon development using the Factor Analysis model(Principal Components method and Normalized Varimax Rotation).The results reveal that the provincial marks of low carbon development are generally low and only nine provinces have high marks(more than 0.80).The results also show significant regional disparity.The provincial marks of the eastern region are higher than both the middle and western provinces of China's Mainland.All of the provinces with high marks(more than 0.90) are located in the eastern region,and those with the lowest marks(0.60) are located in the middle region.Furthermore,regional disparity in low carbon development follows the same pattern as economic development in China.Finally,some suggestions for decision-makers are presented. 展开更多
