Abstract: In recent decades, landscape aesthetic evaluation has been one of the research hotspots in the field of Landscape Science and Ecology, and Landscape Science, Ecology and other related disciplines have been integrated at multiple levels in the research. In order to sort out and summarize the research process and results in the past decade, with a view to find future research trends, we retrieved and downloaded papers on landscape aesthetic evaluation from the WOS database and analyzed them using a bibliometric method based on mathematical statistics. We used Excel to perform a basic analysis of the growth trends in the number of articles, source journals and countries. Co-citation analysis, Cluster analysis, and Keyword co-occurrence analysis were performed with Citespace, and visual graphs were generated. Based on the combing of landscape aesthetic evaluation research, we analyzed and discussed the research frontier and its evolution, key literature and research hotspots, development trend and knowledge structure in this field, and conclude that: (1) the research in the field in recent decade can be divided into the period of theoretical foundation construction, research system improvement and diversified development, (2) Research methods have developed from mainly evaluating landscape photos to the comprehensive use of GIS, VR, Eye-tracking, EEG testing and other technological means, and (3) research hotspots have expanded from Ecology, Scenic beauty evaluation and Landscape management to Rural landscape, Urban public space and Land use, representing the future development trend.

Abstract: This research work was tries to study the risk management practice on public building construction projects and aims to identify the level that use of risk management practice especially in the public building. The data collection method was a combination of interview and questionnaire. Samples were purposively selected from clients, consultants, and contractors representatives who are now actively participating in public building construction projects. For this study, the data was collected using both primary and secondary sources. Depending on the data that was gathered from the respondent to test the level of awareness, identifying the Risk that affect the performance of public building construction project and major risk management practice on public building construction project are considered and the RII was used to rank the factors. This data was analyzed using SPSS of version 22 to perform descriptive statistics. A total of 75 questionnaires were targeted to be distributed and out of those 50 which is 66.67% are successfully responded. The finding from this study revealed that, about (52%) of the project progress is lagging from the schedule. Regarding the awareness of the risk management, (94%) of the respondents where confirmed that they have awareness of risk management ideologies and they are confident enough to implement their knowledge while, (6%) of them have no concept about the risk management. The top five risks that affect the performance of construction project have been identified and ranked. Accordingly; market condition, unexpected inflation, local taxes, inadequate production of raw materials, and the economic condition of country are the top five identified associated project risks.

Abstract: National archaeological site parks are important for scientific protection and sustainable utilization of China's large ancient ruins. It is noteworthy that there is a lack of systematic analyses and dynamic strategies for the planning of archaeological sites parks, a lack of a comprehensive method for extracting earth surface information of archaeological sites, and especially a lack of post procedural research on how human beings transform the surrounding environment of the sites. The traditional research paradigm of archaeological site park planning based solely on archaeology or landscape architecture needs to be updated, as an interdisciplinary discipline, landscape archaeology has the research advantages of being more inclusive and restoring the original state of human land interaction between ancient human and ancient environment. This paper first explains the concept of landscape archaeology and the new vision of Chinese archaeological sites parks, and then, puts forward the lack of cultural connotation in spatial background, and the absence of dynamic thinking in temporal dimension through the analysis of existing domestic archaeological site park. And it is further explored from the “protection of authenticity ", "heritage cultural landscape reproduction", "protection and utilization", "dynamic monitoring" four levels. Finally, from the micro perspective, the paper puts forward a five-stage optimized framework of archaeological site park planning based on the perspective of landscape archaeology.

Abstract: The assessment of the dam failure consequences is fundamental to the dam risk assessment, and the linear weight sum method is generally used. The comprehensive evaluation of dam failure consequences involves many evaluation factors, the dimensions of each factor are inconsistent. The key is to determine the coefficient of the severity degree of dam failure consequences. Based on the traditional methods, a new severity degree coefficient model of the loss of life, economic losses, environmental impact, and social impact is established after taking the current laws and regulations, the range of the severity of the impact, the establishment of normalized function, the introduction of piecewise function and other factors into comprehensive consideration, and use analysis hierarchy process to obtain weight. Apply the improved linear weighting method to the level assessment and rank of the dam failure consequences of Changlong reservoir, Xialan reservoir, Shibikeng reservoir, Longshan reservoir and Lingtan reservoir in Jiangxi Province, and then determine the grade and rank of dam failure consequences according to the calculation results, analyze the corresponding results accurately combined with expertise. The evaluation results and analysis show that if dam failure occurs, the consequences of the five dams are all very serious, it belongs to extraordinarily serious accidents. The severity degree coefficient of dam failure consequences model can reflect the severity degree of dam failure consequences more objectively and reasonably, and it has clear concept, simple calculation, and intuitive process.
