  • Yangon Mega City is densely populated and most urbanization area of Myanmar. Rapid urbanization is the main causes of Land Use and Land Cover (LULC) change and they impact on Land Surface Temperature (LST). The objectives of this study were to investigate on the LST with respect to LULC of Yangon Mega City. For this research, Landsat satellite images of 1996, 2006 and 2014 of Yangon Area were used. Supervised classification with the region of interest and calculated change detection. Ground check points used 348 points for accuracy assessment. The overall accuracy indicated 89.94 percent. The result of this paper, the vegetation area decreased from $1061.08sq\;km^2$ (24.5%) in 1996 to $483.53sq\;km^2$ (11.2%) in 2014 and built up area clearly increased from $485.33sq\;km^2$ (11.2%) in 1996 to $1435.72sq\;km^2$ (33.1%) in 2014. Although the land surface temperature was higher in built up area and bare land, lower value in cultivated land, vegetation and water area. The results of the image processing pointed out that land surface temperature increased from $23^{\circ}C$, $26^{\circ}C$ and $27^{\circ}C$ to $36^{\circ}C$, $42^{\circ}C$ and $43.3^{\circ}C$ for three periods. The findings of this paper revealed a notable changes of land use and land cover and land surface temperature for the future heat management of sustainable urban planning for Yangon Mega city. The relationship of regression experienced between LULC and LST can be found gradually stronger from 0.8323 in 1996, 0.8929 in 2006 and 0.9424 in 2014 respectively.

  • Because of the limited land resources, an efficient land use management to reach the sustainable development policy has become an urgent call in Taiwan. A long-term project entitled 'National land use monitoring program-the establishment of a land use change detection system' has been jointly conducted by both National Central University and Ministry of Interior since year of 2001. The main aim of the project is to use the remote sensing images to detect the land use changes on a national scale. This plan has been put into practice and indeed provides an effective assistance for land management.

  • Land (scape) ecology is a trans-disciplinary science studying the related systems at the earth surface, in their visual, structural and functional aspects. it serves as an umbrella under which abiotic and biotic sciences, in an integrated way, study the for each relevant land attributes and their interrelations. The spatial aspects of these relations have a special interest. Landscape ecology my have a pure scientific purpose, but usually is executed in an applied context, related to land evaluation for land use and conservation. Depending on the aim and application of the study, one of the land attributes may get special attention. Vegetation mapping may contribute to landscape ecological study but also benefit from it especially in case of reconnaissance surveys. This is because in less detailed surveys of any land attribute, like land form, soil, vegetation, one must necessarily apply landscape ecological principles in the survey methodology, including remote sensing.

  • In this study, crosshole seismic test, donwhole seismic test, SPT uphole test, and suspension PS logging (SPS logging) were conducted and the shear wave velocities of these tests were compared. The test demonstrated the following result: Downhole tests showed similar results compared to those of crosshole tests, which is known to be relatively accurate. SPS logging showed reliable results in the case of no casing, i.e. in the rock mass, while, in the case of soil ground, its values were lower or higher than those of other tests. SPT-uphole tests showed similar results in the soil ground and upper area of rock mass compared to other methods. However, reliable results could not be obtained from these tests because SPT sampler could not penetrate into the rock mass for the tests.

  • Land prices reflect not only the uses of land, but the potential uses as well(Plantinga, 2002) so land values can be applied to very effective indices for deciding regional status and growing potential. The purpose of this study is to deduce determinant factors of regional land prices. Principal determinants of regional land prices are analyzed with a hedonic technique and spatial econometric models based on 2001 statistic data of Korea except large cities. The results provide the followings. 1. The spatial effect of rural regions are very little with adjacent regions. 2. The common index of land price is population density and other determinant factors are different depending on land uses.

  • 토지의 개발 또는 보전을 결정하는 적성은 토지가 가진 물리적 특성, 그 토지가 속해있는 주변지역의 특성. 토지의 공간 입지적 특성, 생태환경적 특성 등에 의해 결정된다. 이 논문에서는 전문가조사법과 AHP법을 활용하여 토지의 적성을 결정하는 지표를 분석하고 각 지표가 토지의 적성을 결정하는데 미치는 영향력을 분석하였다. 그 결과 토지의 적성을 결정하는 지표는 개발적성 또는 보전적성별로 각기 다른 지표들이 분석되었고 지표별 영향력도 각기 다르게 나타나는 것으로 분석되었다. 개발적성을 결정하는 지표는 경사도, 표고, 인근용도간 부합성, 용도전용비율, 기개발지거리, 공공편익시설거리의 6개 지표로 분석되었고, 이 중에서 기개발지거리 지표와 공공편익시설거리지표의 영향력이 높은 것으로 분석되었다. 한편 농업성을 결정하는 지표는 물리적 조건 상 경사도가 높지 않은 지역이면서 제도적으로 농지를 보전하기 위해 지정한 농업진흥지역의 비율이 높은 지역이나 농업적 투자를 한 지역(경지정리지역) 또는 그들 지역과 근접해있는 지역인 것으로 분석되었다. 한편 보전지역은 생태자연도상의 상위등급지표가 가장 중요한 것으로 분석되었고 그 다음이 각종 법에서 보전지역으로 지정한 면적비율인 것으로 나타났다. 이러한 지표별 영향력을 반영하여 적성평가를 실시해본 결과 적성을 판단하기 어려운 중간 적성값의 필지보다 개발적성과 보전적성이 강조된 양극단의 적성값을 가진 필지비율이 증가하는 것으로 분석되었다.

  • The coupled model (SMART) of dynamic meteorology model and particle dispersion model was developed. The numerical experiment on the relationship between change of land use and diffusion behavior in complex terrain was carried out using this model. It tried to investigate the change of particle diffusion behavior and local weather under the condition in which land-land breeze and sea breeze and mountain breeze intermingled. The numerical experiment results are as follows; 1) The more complicated local circulation field of the interaction of sea breeze, mountain breeze and Land -land breeze is formed. Then, the region circulation in which the urbanization is specific by location of the region is strengthened and is weakened. 2) Though in the region with dominant sea breeze, Land-land breeze does not appear directly, the progress of the sea wind to the inland is affected. 3) In the prediction of the air diffusion, emission high quality and accurate information of the emission site are important. That is to say, the dispersion predicting result which emission high quality and small error of the site perfectly vary for Land - land breeze in the effect may be brought about.

  • Land art has always ben considered as a similar but distinctly separate field from landscape architecture. Landscape architechs look to land art for inspiration and new concepts, but has always hesitated to define their field as an "art." But as more and more design projects for social spaces are being commissioned to artists, especially land artists, the distinction between the two fields are starting to blur. "Art or Social service\ulcorner" has been a question that has been asked in the field of landscape architecture throughout the 20 th century. By reviewing the concepts behind various land art projects, this paper seeks to undermine several misconceptions that has prevented landscape architects from wholeheartedly embracing land art as a expansion of their own field. Land art, as a new form of sculpture, sought to create art forms that were not looked at but experienced from the inside. Land art challenges the principle of the picturesque and the pictorialized view of nature. Land art was influenced by a new interest in prehistoric art, and sought to reestablish communication between the artist and the public. Also, land artists acknowledge the social responsibilities of art and presents the concept of art as a community activity. As can be seen by the concepts behind the works of land artists, the dichtomy of the artistic and social aspects of landscape architecture can be reconciled, and land art can serve as a model for a expanded field of landscape architecture.dscape architecture.
