  • Solutions of many landscape problems depend on area-wide assessment and interpretation of spatial and physical characteristics over the study area. The authors argue that the public awareness for an area-wide urban landscape appears to be very low due to limited chance to the information. Acknowledging these constraints, an operational, user-friendly information system has been developed by combining internet technology with GIS. In particular, integration among satellite data and digital maps takes advantage of each component, and enables the landscape structure to be visualized, interacted with and deployed all on the Web. The 1m resolution IKONOS data realistically identified the major type of landscape by large scale spatial precision while TM data revealed successfully the major parameters that influence an area-wide spatial structure in the study area. This system would play a crucial role in improving the public awareness for area-wide landscape information if it is operationally introduced into the Government since the highly user-friendly interface based on image maps provides a completely new means for disseminating information for area-wide landscape in a visual and interactive manner to the general public.

  • 본 연구에서는 경북 봉화군을 대상으로 하여 지속가능한 토지이용을 위한 생태계정보를 추출하기 위하여 경관생태학적 방법에 의한 생태계의 종합적 건강성을 평가하였다. Landsat TM 위성영상을 가지고 봉화군에 대한 토지피복분류를 실시한 후, 산림지역에 대하여 경관지수를 적용하여 생태계 건강성에 대한 면별 비교평가를 실시하였으며, 그 결과를 정규식생지수(NDVI)와 비교하였다. 경관지수를 이용한 생태계 건강성 종합평가에서는 석포면, 재산면, 소천면이 가장 양호한 것으로 평가되어 지역의 생물종의 풍부도와 다양성이 높을 것으로 보여진다. 봉화읍은 10개 면 중에서 생태계 건강성이 가장 낮은 상태로 나타났다. 정규식생지수(NDVI)와 비교하였을 때, 재산면, 춘양면, 소천면의 수치가 가장 높고, 봉화읍의 수치가 가장 낮은 것으로 나와 춘양면을 제외한 결과는 생태계 건강성 종합평가와 비슷한 결과를 보여주었다. 앞으로 보다 많은 보완적인 연구가 필요하지만, 경관지수를 이용한 경관규모 생태계 평가기법은 지속가능한 토이지용과 관련한 생태계 정보를 제공할 수 있을 것으로 기대된다.

  • Recent landscape changes from human activities, such as agricultural development and urbanisation frequently result in the loss of habitats, the reduction in habitat patch size and an increasing isolation of habitat patches. However, there is little information on woodland changes in agricultural landscapes. Therefore, the aim of this research was to assess spatial characteristics and changes of woodland in an agricultural landscape and how these may have had an impact on ecological process for 33 years. One of the agricultural landscape character units was analysed based on aerial photographs from 1976, 1983, 1994, 2002 and 2009 in Gwangju city. The results indicated that landscape ecological metrics clearly showed that they could be used to monitor changes of woodland ecological conditions during the past 33 years. The results imply that particularly human activities have been leading to the decrease of the mean size of woodland patches and finally result in woodland isolation. These changes may have a negative impact on woodland bird species in the study area. This woodland information can be used to identify the potential and specific needs for setting priorities for conservation planning.

  • In the field of environmental landscape architecture, the internet medium is used as an effective communication tool not only in the private level but also in the policy level. Recently, the active utilization of mobile web service is emphasized as the time changes, but there is not much improvement or advance in services due to lack of relevant studies. Therefore, this study is intended to provide basic data needed for improvement and advance by researching the quality of mobile web service among multichannel services provided in environmental landscape architecture related internet media. The model for measuring service quality is SERVQUAL, which was verified in the study of Choi(2015), Choi and Koo(2016), and the final valid samples are total 230. First, the subjects were analyzed as the representative media that are possible to acquire comprehensive knowledge related to environmental landscape architecture. Second, the highest importance level in each subsection was 'protection and security maintenance of customer information' followed by 'Reliability about accurate information supply'. Regarding performance level, 'Reliability about accurate information supply' and 'professional knowledge to communicate with users' are highly evaluated. Third, regarding Importance-Performance Analysis(IPA), the first priority management should is 'Tangibles', and the next are 'Responsibility' and 'Empathy'. The ones for maintenance of the status quo are 'Reliability' and 'Assurance', and there is none for effort reduction. Meanwhile, regarding the importance of each factor and difference in the quality of PC web service and mobile web service studied before, the biggest difference is in 'Tangibles', followed by 'Assurance', 'Empathy', 'Responsibility' and 'Reliability'. It is suggested that the revitalization of Landscape information science(LB1106) presented in the National Science&Technology Standard Classification System is needed. In the future, it is necessary to research the change trend on users' response through continuous evaluation of improved mobile web service.

  • Among components of digital topographic maps used officially in Korea, only contours have 3D values except buildings and trees that are demanded in landscape planning. This study presented a series of processes for 3Dreconstructing landscape features such as terrain, buildings and standing trees using LiDAR (Light Detection And Ranging) data and aerial digital photo graphs. The 3D reconstructing processes contain 1) building terrain model, 2) delineating outline of landscape features, 3) extracting height values, and 4) shaping and coloring landscape features using aerial photograph and 3-D virtual data base. LiDAR data and aerial photograph was taken in November 2006 for $50km^{2}$ area in Sorak National Park located in eastern part of Korea. The average scanning density of LiDAR pulse was 1.32 points per square meter, and the aerial photograph with RGB bands has $0.35m{\times}0.35m$ spatial resolution. Using reconstructed 3D landscape features, visibility with the growing trees with time and at different viewpoints was analyzed. Visible area from viewpoint could be effectively estimated considering 3D information of landscape features. This process could be applied for landscape planning like building scale with the consideration of surrounding landscape features.

  • 본 논문에서는 직접조작 방법을 이용하여 대화형 유전자 알고리즘(IGA)의 진화성능을 향상시키고 세대를 반복하면서 다양한 해를 얻을 수 있음을 NK-Landscape를 이용해 분석한다. 또한 NK모델을 이용하여 직접조작의 진화과정을 분석하기 위한 IGA 인터페이스를 생성한다. IGA를 이용한 진화는 특성상 적온 수의 개체와 세대수로 제한되기 때문에 지역해에 빠질 수 있는 문제점이 있다. 이러한 IGA 의 제약사창을 극복하는 방법으로 직접조작을 이용할 수 있으며 이 방법은 사용자가 원하는 개체를 생성할 수 있도록 진화과정에서 유전자를 직접 변경한다. IGA 에서 진화성능의 향상과 다양한 해외 생성을 분석하기 위하여 진화연산자인 교차, 돌연변이와 직접조작 방법의 성능을 비교 분석한다. Kauffman이 제안한 NK-Landscape로 진화과정에서 해공간이 얼마나 "ruggedness" 한지와 다양한 진화연산자에서 어떤 성능을 갖는지 분석할 수 있다 실험을 통해 3D 꽃 디자인 문제에서 NK-landscape기반 IGA인터페이스를 이용하여 IGA 해공간을 분석하고 교차, 돌연변이와 직접조작 방법의 성능을 비교함으로써 직접조작 방법으로 더 빠른 시간에 다양한 최적해를 찾을 수 있음을 알 수 있었다.

  • It is widely recognised that changes in size and isolation of habitat patches have a negative impact on species richness and the distribution and persistence of populations. Thus, the aim of the research was to analyze the change, distribution and spatial characteristics of woodlands in an urban fringe landscape. The results indicated that there was a common trend of woodland loss across all landscape types while no new woodlands were established during 1976 and 2009. Small patches (less than 5 ha in size) were particularly vulnerable to and more likely to disappear due to human activities such as urbanisation. Changes in woodland cover were clearly observed between 1976 and 2009. Loss of many woodlands was caused by residential and infrastructural developments. As a result, woodlands were becoming smaller and more isolated. This trend probably had adverse effects on biodiversity. This woodland information can be used to identify the potential and specific needs for conservation planning in rapidly developing urban areas.

  • The purpose of this study is to reveal network potential among agricultural villages focused on landscape and amenity resources. For this study, we conducted Social Network Analysis (SNA) utilizing existing landscape resource database. As a result of the study, major landscape types shared among villages were found for each city. For example, agricultural and residential landscapes were identified as major types for Danjin city. Add to major landscape resources, in Dangjin city, Habduk village were recognized as a core. Seokmun, Daehoji, Woogang, and Sunseong villages were widely found as the sub core group. For Seosan city, Jigok, Palbong, and Kobuk villages were widely recognized as core group. Most of villages which indicated the highest degree centrality were superior in terms of the number of total landscape resources as well as landscape type diversity. These results can be useful for initial planning process when considering major theme for landscape-based network organization. Also, this information will be helpful for planning stage through the specification of the potential role of each village in overall network.
