After mapping, a comprehensive and detailed large-scale landslide inventory that contains 2 924 large-scale landslides was obtained. We analyzed the spatial distribu-tion of landslides with seven influencing factors, including elevation, slope angle, aspect, curvature, lithology, distance to a river, and distance to the fault. Landslide Number, Landslide Area, Landslide Number Density(LND), and Landslide Area Percentage(LAP) were selected as indexes for the spatial distribution analysis. The results show that the number and area of landslides in the elevation range of 1 000–1 200 m is the highest. The highest number of landslides was observed in the slope angle of 25°–30°. North-facing slopes are prone to sliding. The area and number of landslides are the largest when the slope curvature ranges from-1.28 to 0. The LND and LAP reach their maxima when the slope curvature is less than-2.56. Areas covered by the Tertiary stratum with weakened fine-grained sandstone and siltstone show the highest LND and LAP values. Regarding distance to a river, the LAP peaks in the range of 300–600 m, whereas the LND peaks in an area larger than 2100 m. The values of LND and LNP rise as the distance from the faults increases, except for the locations 30 km away from active faults. This phenomenon is because active faults in this area pass through the plain areas, while landslides mostly occur in mountainous areas. The cataloging of landslide development in Xianyang City provides a significant scientific foundation for future research on landslides. In addition, the spatial distribution results are useful for landslide hazard prevention decisions and provide valuable references in this area.展开更多

[Method] Taking the landscape design of Xiweiyuan Park in Xianyang City as an example,how to express the regional characteristics in the modern garden designs was discussed from the perspective of design principle,layout of planning and landscape analysis. [Conclusion] Garden sites are bathing in certain regional cultures,which could demonstrate overall atmosphere through the spatial structure reflected by concrete material elements such as buildings,architectural oddments,plants and their combinations,thus the essence of garden characteristics is its territoriality. To regain the sense neglected by modernism,the danger of assimilation brought by globalization to the regional culture should be avoided; to solve the problems of losing distinctive characteristics and convergence of landscape design in the garden design,it should be started from natural environment,and then a garden site recognized by both culture and sensibility of people should be created for both mental and physical rest of people.展开更多

This has been a worldwide problem, which greatly restricts the exploitation and utilization of geothermal resources. Based on a large amount of experiments and researches, the reinjection research on the tail water of Xianyang No.2 well, which is carried out by combining the application of hydrogeochemical simulation, clogging mechanism research and the reinjection experiment, has achieved breakthrough results. The clogging mechanism and indoor simulation experiment results show: Factors affecting the tail water reinjection of Xianyang No.2 well mainly include chemical clogging, suspended solids clogging, gas clogging, microbial clogging and composite clogging, yet the effect of particle migration on clogging has not been found; in the process of reinjection, chemical clogging was mainly caused by carbonates(mainly calcite), silicates(mainly chalcedony), and a small amount of iron minerals, and the clogging aggravated when the temperature rose; suspended solids clogging also aggravated when the temperature rose, which showed that particles formed by chemical reaction had a certain proportion in suspended solids.展开更多

[Method] By using precipitation observation data at 11 meteorological stations in Xianyang from 1960 to 2009, climatic characteristics of the rainstorm in Xianyang were analyzed. [ Result] Annual occurrence frequencies of the rainstorms in each county (city and district) of Xianyang were all less than 1. Number of the rainstorm day was the most in Wugong and the fewest in Qindu station. Interannual variation of the rainstorm was big, and presented less-more- less-more tendency. Rainstorm appeared from April to October, and was the most during July -August. Heavy rainstorm appeared from May to September. Rainstorm had short duration and big intensity, with nocturnal majority. Regional rainstorm in Xianyang occupied 77% and was the most. Rainstorm mainly occurred in single day, and occurrence probability of the continuous rainstorm was very low. [ Conclusion] The research laid foundations for doing this kind of weather forecast well, going after advantages and avoiding disadvantages, preventing and reducing natural disasters.展开更多

However, its urban spatial structure is still ambiguous due to the insufficient historical literature and archaeological findings, thereby enforcing the breakthrough of extant research visions and methods. This paper is a tentative response to this issue from the perspective of urban planning. Firstly, the paper infers that the method of Bianfang Zhengwei [Orientation Identification and Position Determination] has been applied in the planning of Xianyang in the Qin Dynasty based on the study of the planning tradition of pre-Qin and Qin-Han dynasties. Secondly, it recognizes and reorganizes the related literature documents and archaeological findings according to the clue of "Core Establishment" and "Orientation Determination," to identify the axis system of Xianyang with the Polar Temple and Epang Palace as the core, based on which the spatial structure of Xianyang is revealed. Ultimately, it expounds the methodological and practical significance of this study.展开更多
