Coastal dunes have many environmental and ecological socio-economic importances; various human activities, however, have impaired their structures and functions over the years. In 2016, environmental survey on coastal sand dune was carried out to report the present status and update the coastal sand dune list in 2001. This research analyzed the survey data in terms of geomorphological and socio-economic aspects. A list of the 189 coastal sand dune and information was updated by province. A 36.5% reduction in coastal sand dune area have been identified for using agricultural land, development area since the approximately 1940-50s. Development area in coastal sand dune covered small area as 5%, the use intensity was relatively hard. Furthermore, the difference by province also showed. Approximately 80% of the development area was concentrated in 20% of total sand dune several sand dune. It is generally accepted that coastal sand dunes were exposed high development pressure. However the result means that the general brief dose not apply for all sand dune. Therefore, characteristics of each sand dune should be analyzed and concerned the diverse management plans.

We investigated the pattern of floral diversity including naturalized plant species and three ecological factors (area, elevation and distance from mainland) of plant species on 53 uninhabited islands in Gyungsangnam-do, southeastern South Korea. A total of 206 taxa in 67 families were observed, and the species of Compositae was most common. Thirteen taxa in eight families of the naturalized plants were observed on 33 islands. The numbers of total plant species, area and elevation were significantly correlated, but no relationship with distance from the mainland was observed. In addition, no relationship was found among the numbers of naturalized plants, area and elevation. However, the average rate of naturalization on islands with different elevations differed significantly, indicating the smallest proportion of naturalized plant species was on high islands. Multiple regression of total species richness identified elevation as a significant factor, while no significant variables were correlated with naturalized plant species. Nonmetric multidimensional scaling (NMS) ordination identified three major variables, distance from mainland, number of naturalized plant species and elevation. These findings indicate that the geography of islands such as area and elevation affected the species richness of plants on uninhabited islands, while human disturbance had a greater effect than geography on the species richness of naturalized plants on islands in southeastern South Korea.

지역과 지역지리학이 재흥하고 있다. 새로운 지역지리학의 대두를 이해하기 위해서는, 자본주의 체제의 변화에 따라 새롭게 구성되는 공간적 재현 양식의 하나로서 지역의 의미도 변화한다는 점을 주목할 필요가 있다. 특정한 자본주의 체제는 자신에게 적합한 재현 양식을 요구하며 지역도 그 하나이기 때문이다. 20세기에 발전한 포드주의 자본주의 하에서, 지역 발전은 서구적 사회경제 체제의 공간적 확산과정으로 인식되었다. 국가는 조절기구로서 자본주의 체제의 확산을 촉진시키는 하부구조를 제공하고 지역적 공간 분업 구조를 조절함으로써 경계성장을 지원하였다. 지역 개발론은 이러한 국가개입에 적절한 이념과 정책 수단을 제공하는 역할을 했으며, 지역은 발전의 공간적 확산 과정을 측정하고 인식하기 위한 지리적 정보를 조직하고 분류하는 수단이었다. 지역개발론은 전통적인 지역 개념을 형식적 분류개념으로 왜소화시켰다. 포디즘에서 유전적 축적으로 자본주의 체제가 이행하면서, 지역이 다시 그 정체성과 진정성을 획득하고 있다. 지역지리학은 이러한 지역 재흥의 추세 속에서 적절한 연구 방법으로 성과를 올릴 수 있다. 유효한 방법의 하나가 문화생태학적 지역에 대한 역사적 접근이라고 믿는다. 문화생태학적 지역이 유연적 축적체제 하에서의 지방정부의 문화전략에 부합하고, 지역성을 서사적 내용과 미학적 경관으로 담아 낼 수 있기 때문이다.

This study constructed a high-resolution bioclimatic classification map of South Korea which classifies land into homogeneous zones by similar environment properties using advanced statistical techniques compared to existing ecological area classification studies. The climate data provided by WorldClim(1960-1990) were used to generate 27 bioclimatic variables affecting biological habitats, and key environmental variables were derived from Correlation Analysis and Principal Component Analysis. Clustering Analysis was performed using the ISODATA method to construct a 30'(~1km) resolution bioclimatic classification map. South Korea was divided into 21 regions and the results of classification were verified by correlation analysis with the Gross Primary Production(GPP), Actual Vegetation map made by the Ministry of Environment. Each zones' were described and named by its environmental characteristics and major vegetation distribution. This study could provide useful spatial frameworks to support ecosystem research, monitoring and policy decisions.

This work aims to establish the landscape ecological countermeasures to improve the sustainability of urban mountain forest and to enrich the biodiversity in twenty mountains of the Seoul Metropolitan City. Landscape ecological analysis was conducted based upon various criteria, such as area and elevation of mountains, flora, naturalized plants, vegetation, forest types, mountain trails, and public facilities. Various measures were suggested for the better maintenances of floristic diversity, introduced plants, vegetation and forest types of urban mountain forests. Sustainable recommendations for land use adminstration were developed for the preparations of a climate change-adapted urban mountain forests, as well as rational managements of ecosystem, walking trails, and public facilities within mountain forest. Rich and diverse natural vegetation as well as high floristic diversity were reported at mountains with higher elevations, larger area size, and rich landscape diversity. Mountains with low elevation, small size with easy public access, however, might require an urgent action to decrease the burdens by anthropogenic disturbances and urban development.

This article is written in the viewpoint of landscape ecological geography. The coast of South Chung-chong Province will make new characters of region in the development strategies program. This study is to describe geomorphological landscapes of South Chung-chong Province relating with it's environment based on the coast. Although landforms constitute prominent landscape features as tidal flats and rock cliff do, it is nonetheless the features such as beaches, sanddunes, and coastal plains that have various ramifications for human communities. Tidal flats, beaches and coastal sanddunes are special in that their formation is attributable to the combined action of tidal flows, waves and winds. To some extent, the erosion of sand has been a global phenomenon. Human impact are involved. The influence of globalization and expansion of liberal trade appears in regions variously. Individual regions need to secure its competitiveness in the world market. Regions are not value-neutral abstract conception, but must be informal commercialized characters of region. The coast of South Chung-chong Province has experienced rapid and dramatic changes. In industrial times, the middle of west coast Korea turned into a major reclamation at larger scale. Reclaimed land was based on location of industry and mechanized agriculture. The west coast highway and bridges between island and land contributed to the development of west coast transportation. As information society matured, trend and value are changing. Environment and ecology emphasize and rediscover the value of tidal flats and sanddunes. The west coast region now receives attention as eco-tour and sustainable course.

The study examined the influence of climate and soil dynamics on vegetation health across the ecological zones in Rivers State, Nigeria. MODIS imagery was used to assess the vegetation health through NDVI and point grid pattern of meteorological data for total precipitation (TP), air temperature (AT), soil moisture (SM) and soil temperature (ST) of 2000, 2003, 2006, 2009, 2012 and 2015 were used for the study. Descriptive and inferential statistics were used for data analysis. Findings showed that NDVI ranged between 0.420 and 0.612 in the freshwater swamp (FWS) while between 0.465 and 0.611 in the rainforest and the NDVI in the mangrove was generally low. The highest mean AT was experienced in the mangrove ecological zone and the least was experienced in the rainforest. The mean SM was generally highest in the rainforest with highest value in 2000 (774.44 m³/m³). The ST was highest in the mangrove and the least was experienced in the rainforest while the TP was highest in the mangrove. NDVI correlated significantly with SM (r=0.720; p<0.05) and ST (r= -0.493; p<0.05). NDVI, SM, TP and ST significantly varied among the ecological zones. Regression analysis showed that vegetation health was significantly related to the combination of soil temperature and soil moisture (R²=0.641; p=0.000). Thus, monitoring the factors that affect vegetation health in a changing climate and soil environments is highly required.

복지지리학은 불평등과 사회정의를 강조하는 인문지리학의 한 분야이다. '사회정의'는 '인간의 욕구'와 더불어 포스트모던이후 복합적 담론에 대항하여 공간의 해석에 보편적으로 적용될 수 있는 가치기준으로 등장하였다. 복지지리학도 사회정의론을 바탕으로 복지개념을 재정립하고 복지를 향상시키려 노력하였으며 공간정의의 측면에서 분배정의를 논하였다. 본 논문은 사회정의의 다양한 이론들을 통하여 복지의 공간적 불평등과 정의로운 복지 분배가 가지는 의미를 살펴보고자 하였다. 그리고 평등, 효율성, 형평성, 공정성과 같은 사회정의를 평가하는 다양한 기준들을 복지지리학의 측면에서 복지의 정의로운 분배평가와 연계시키고자 하였으며 이를 통하여 결과적으로 복지의 평등한 분배에 기여하고자 하였다. 마지막으로 사회정의의 평가기준들을 복지 공간의 평가에 적용하는 데 있어서의 한계점 등을 논의하였다.
