In the process of geothermal exploitation and utilization, the reinjection amount of used geothermal water in super-deep and porous reservoir is small and significantly decreases over time. 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.

China City Planning Review 2018年第2期27卷 66-75页

作者： Guo Lu Li Min School of Architecture Tsinghua University

As the capital of the first unified Chinese empire, the planning and design of xianyang in the Qin Dynasty is of significant value in the historical research of urban planning. 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.

[Objective] To explore and analyze the theories and practical approaches to construct garden sites with regional cultural characteristics. [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.

[ Objective] The research aimed to analyze climatic characteristics of the rainstorm in xianyang in recent 50 years. [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.
