  • Urban geology is the study of urban geologic environments to provide a scientific basis for rational land use planning and urban development and provides information on geologic environments as a basis for city planners. Based on AEG recommendations, urban geological studies covered the urbanism and historical backgrounds, geological setting, engineering geological constraints and environmental assessments of understudied cities. The aim of this study is to provide a good view of urban geology of Tabriz city the capital of East Azerbaijan province in Iran. The topics of discussions about Tabriz city urban geology are included geologic (geomorphology, geology, climatology and hydrogeology), engineering geological (earthquake, landslide and geotechnical hazards investigations) and environmental characteristics (air, soil and water hazards assessment).The results of the urban geologic studies indicated that Tabriz city in terms of engineering geological and environmental constraints is at high risk potential and in terms of seismic activity and landslide instability is highly potential. In terms of air, soil and water pollution there are many important environmental concern in this city.

  • The development of science and transportation technology leads to the increase of inter - city networks that play an important role in urban growth. Overall, numerous studies based on network theory pay attention to positive effects of urban network on urban growth. However, some studies have pointed out the negative effects of inter-city interactions such as straw effects. This implies that the network between cities may not be positively correlated with urban growth, and that the direction of the influence may vary from a certain threshold, such as the marginal utility curve. In this context, the purpose of this study is to measure the impacts of network with central city on urban growth in the capital region and examine the relationship between urban network and growth. Two multiple regression models are employed with changes in population and employment as dependent variables. The urban network index and other control variables are used as independent variables. Especially, the urban network indexes are used in quadratic forms to examine non linear relations with urban growth such U-shape or an inverted U-shape. The results show that the relationships between networks with the central city and urban growth are not a simple linear, and the influence can be changed from the critical point.

  • For the comfortable housing life, comfortable and pleasant urban environment should be created for the people living in house and in city. There are lots of environmental conditions in city affecting house and life. Also most of all the noise pollution have been become major factor that makes people's life uncomfortable. Recently soundscape researches have been performed to create comfortable urban environment and various studies on the evaluation of urban environmental sounds are now undergoing. This study aimed to analyse the subjective characteristics through the subjective evaluation to the sounds measured with physical parameters and eventually to find out alternative evaluation method for urban environmental sounds. Adjectives applied to previous studies were used for the subjective evaluation and sound sources recorded in specific places were presented with picture at the same time. As a result, new physical parameters such as Lmax, Unbiased Annoyance, G, N and EmT have a feasibility to evaluation of urban environment sounds in terms of acoustic comfort.

  • By limiting population and land resources, a high-density urban form has become the inevitable choice for central cities in the rapid growth of many large cities in China. Due to the shift in urban growth and focus, high-density urban areas require restoration and improvement. This study intends to combine ancient and new districts, establish strategies for enhancing urban function, spatial utility, industry, and transportation, and thus enhance regional holistic effectiveness, by performing in-depth research.

  • 한국도시지리학의 태동기 ${\rightarrow}$ 성립기 ${\rightarrow}$ 전환기 ${\rightarrow}$ 절정기로 구분될 수 있으며, 이러한 추세가 지속된다면 향후 성숙기의 단계로 접어들 것으로 전망된다. 본 연구는 한국도시지리학의 연구동향을 회고하기 위해 1960~2012년의 62년간 출간된 논문 686편과 단행본 177권을 연구영역별 연구지역별 분석방법별 및 학회지별로 고찰한 것이다. 도시지리학자의 수적 증가에 따라 학자들 간에 상호관계가 더 복잡하고 다양하게 나타나고 있으나 학파의 징후는 아직 보이지 않고 있다. 도시연구지역은 여전히 수도권을 대상으로 한 논문이 많고, 해외의 경우는 미국도시로부터 벗어나 다양화되어가고 있음이 밝혀졌다. 도시연구방법은 계량화가 더 많아지는 경향이 있고, 2000년 이후부터는 한국도시지리학회에 게재된 논문이 국내 학회지 중 가장 많았다.

  • 우리나라의 지리학계는 대한지리학회 창립 50주년을 맞이하는 시점에서 조망해 볼 때에 많은 발전이 있었다. 특히 도시지리학 분야는 8.15광복과 더불어 성립기를 맞은 후, 정 립기, 전환기, 절정기, 성숙기를 거치면서 가장 빠른 속도로 발전해왔다. 도시연구의 주제는 도시화, 도시구조, 도시체계, 도시경제 등의 영역이 중심을 이루었고, 분석방법은 정량적 연 구방법을 적극적으로 활용하였다. 또한 도시지리학 연구는 수도권과 영남권을 대상으로 한 논문이 많았으며, 발표된 논문의 6할 이상은 각대학의 紀要에 발표되었고 학술지 중에서는 대한지리학회지에 게재된 논문이 가장 많았다.

  • Studies on landscape ecology have focused on conceptual aspects, while empirical focus for spatial planning has been rarely conducted. This study conducted an empirical analysis to enhance landscape ecological performance of urban developments using landscape ecology. To do so, concrete criteria and standards to analyze structural, functional and variational mechanisms of urban landscape ecology were developed. An integrated landscape ecology assessment model that can be applied to urban development planning was established by combining the criteria. Next, Landscape Ecological Management System (LEMS) was developed to implement an integrated assessment using GIS. To verify the effectiveness of the system, a case study was conducted using LEMS on Byulnae City in the Seoul Metropolitan Area. The LEMS can be useful for urban planners and policy makers in their selection of desirable planning alternatives. Moreover, the LEMS developed in this study can be a useful tool for academia in terms of the implementation of further related studies, and for planning professionals in their environmental impact assessment tasks.
