This study aims to assess habitat feature on the large-scale spawning ground of the Boreal Digging Frog Kaloula borealis in Daemyung retarding basin of Daegu, and to analyze the relationships between species abundance and meteorological factors for each habitat. Fifty-seven(57) pitfalls were installed to collect species abundance of 4 survey regions, and high-resolution satellite image, soil sampling equipment, digital topographic map, and GPS were used to develop habitat features such as terrain, soil, vegetation, human disturbance. The analysis shows that the frog is most abundant in sloped region with densely herbaceous cover in southern part of the retarding basin. In the breeding season, lowland regions, where Phragmites communis and P. japonica dominant wetlands and temporary ponds distributed, are heavily concentrated by the species for spawning and foraging. Located in between legally protected Dalsung wetands and lowland regions of the retarding basin, riverine natural levee is ecologically important area as core habitat for Kaloula borealis, and high number of individuals were detected both breeding and non-breeding seasons. Temperate- and pressure-related meteorological elements are selected as statistically significant variables in species abundance of non-breeding season in lowland and highland regions. However, in sloped regions, only a few variables are statistically significant during non-breeding season. Moreover, breeding activities in sloped regions are statistically significant with minimum temperature, grass minimum temperature, dew point temperature, and vapor pressure. Significant meteorological factors with habitat features are effectively applied to establish species conservation strategy of the retarding basin and to construct for avoiding massive road-kills on neighboring roads of the study sites, particularly post-breeding movements from spawning to burrowing areas.

낙동강 유역의 고라니 공간분포와 물리적 환경요소와의 관계분석

노백호(Paik-ho Rho) 계명대학교 낙동강환경원 2012 環境科學論集 Vol.16 No.1

This study aims to identify the effects of topographic characteristics and human disturbances on spatial distribution of Korean water deer (Hydropotes inermis argyropus) in Nakdong river basin. GIS algorithm was used to create 171 random sites, and physical environments such as elevation, slope, road density, human population density and % urbanized area were calculated for each site. These physical environmental characteristics of the random sites were compared with those of 171 water deer observed locations. The results showed that human disturbances were more effective in limiting spatial distribution of the species than topographic characteristics. That is, water deer are more likely to be found in areas free of human disturbances, including low road density and sparsely-populated area, although in high elevation with sharp slope. Spatial distribution of the water deer in Nakdong river basin have potentially used to implement stream restoration projects through the identification of observed locations and suitable habitat for the species.

From December 2014 to November 2015, an automatic weather system (AWS) was installed over a wide road of Daegu to continuously measure meteorological factors and surface temperature. We investigated the effective operating period of the clean-road system using the daily maximum and minimum air and asphalt surface temperatures, with the aim of creating an optimum thermal environment. The clean-road system was installed over a part of the broad way of Dalgubul(Dalgubul-Daero) by Daegu Metropolitan City in 2011. Until now, the clean-road system has been operated from the middle of April to the end of September. We assumed that it was desirable that the clean-road system could be operated when the discomfort index was above 55. In conformity with the conditions, we concluded that the optimum operation period of the clean-road system is from the end of March to about the middle of October.

이진영 ( Jin Young Lee ),노백호 ( Paik Ho Rho ),이장원 ( Jang Won Lee ) 한국환경생태학회 2010 한국환경생태학회지 Vol.24 No.6

서식지 파편화로 발생하는 야생동물과 차량과의 충돌사고(이하 `로드킬`)를 방지하기 위해 2000년대 후반부터 야생 동물이동통로가 활발하게 설치되었으나 로드킬 발생은 여전히 감소하지 않고 있어 야생동물이동통로의 실효성 분석이 필요하며, 설치 이후 단편화된 유지관리로 인해 야생동물이동통로에 대한 평가 및 기능개선을 위한 관리기법이 부족한 실정이다. 이에 본 연구에서는 야생동물이동통로의 유지관리를 위한 기본방향 및 관리기법을 제시하기 위해 현재 설치·운영되고 있는 367개 이동통로에 적용할 수 있는 평가항목과 항목별 중요도를 AHP 기법에 의해 파악하였다. 분석결과, 평가항목은 3단계로 구분할 수 있었으며 총 l0개 평가항목이 도출되었다. 야생동물이동통로의 유지관리를 위한 우선순위 도출을 목표(Level 1)로 시설인자, 환경인자, 동물인자, 관리인자로 구성된 Level 2의 중요도 분석에서는 환경인자가 가장 중요한 것으로 나타났다. Level 3에서는 구조 적합성(시설인자), 주변지형과의 조화(환경인자), 야생동물 이용빈도(동물인자), 모니터링 기기 운영여부(관리인자)가 중요 평가항목으로 조사되었다. 즉 야생동물이동통로의 유지관리를 위해서는 주변지형과의 조화와 야생동물 이용빈도를 우선적으로 고려해야 할 것이다. 이 같은 연구 결과는 우리나라에 설치되어 있는 야생동물이동통로의 유지관리 방향 및 각 이동통로의 정비전략을 모색하기 위한 평가자료로 활용될 수 있다. The rapid increase of wildlife passage installation since the late 2000s was aimed to reduce roadkill caused by habitat fragmentation and losses related to road construction, but wildlife-vehicle collisions are now still occurred even near the wildlife passage area. This is the reason that the effectiveness of wildlife passage have not been evaluated in combination with absence of monitoring data and management strategy of the wildlife passage. The AHP method are used, in this study, to identify the evaluation factors affecting the effectiveness of the present 367 wildlife passages in a mitigation measures to reduce road effects on wildlife species. Ten evaluation factors are derived from third levels in the AHP analysis. Priority setting to identify appropriate management strategies in first level is selected among four second levels on facility, environment, wildlife species and management tool. The AHP analysis suggested that neighboring environments are the most important factor at the second level, and passage structure, harmony with natural surroundings, wildlife occurrence and monitoring of the passage are also important factors at the third levels. In summary, effective measurements of wildlife passage management is based on managing the passage with neighboring topography and natural surrounding. This is useful to establish wildlife passage management strategy in order to reduce the negative effects of roads on wildlife species.

본 연구는 2001년부터 2006년까지 김포 홍도평야에 도래하는 재두루미와 황오리의 개체수 변동추이를 파악하기 위해 겨울철새 도래시기인 10월부터 이듬해 3월까지 총 541회에 걸쳐 현지조사를 실시하고, 연도별 변동추이를 분석하였다. 홍도평야에 도래하는 겨울철새는 재두루미(Grus vipio) 황오리(Tadorna ferruginea) 등 10여종이 관찰되었고, 두 종의 도래시기는 10월부터 이듬 해 3월까지이며 재두루미는 12월 그리고 황오리는 1월에 최대 개체수가 발견되었다. 일반적으로 비가 오거나 흐린 날 보다는 맑거나 눈이 오는 날 상대적으로 많은 개체수를 관찰하였다. 조사 결과에 따르면, 김포 홍도평야에 도래하는 재두루미와 황오리는 매년 증가와 감소를 반복하며 비슷한 변동추이를 나타내고 있어, 종간의 상호보완 관계를 유추할 수 있다. The temporal changes in Grus vipio and Tadorna ferruginea populations in winter were studied on the Hongdo Plains in Gimpo City, Korea, for 6 years from 2001 to 2006. During the survey period, more than ten species were recorded every winter, including G. vipio and T. ferrugineas, which arrived on the plains in October and over-wintered until the following March. In particular, the highest population densities of G. vipio and T. ferruginea were in December and January, respectively. More individuals were observed on snowy and clear days, but rain reduced the number observed. This survey suggests that the populations of these two species undergo annual cycles, and that each species facilitates the other.

국립공원에 서식하는 생물종과 서식지 간의 관계를 공간적 평가에 활용하기 위해 생물종의 생태적 특성, 공간 유형, 식생군락, 지형 및 지질 조건을 기준으로 서식지 유형 분류 체계를 개발하고 서식지 분류 지도를 제작하였다. 서식지 유형의 체계적 분류 및 판정을 위해 분류기준표를 제작하였다. 분류 체계는 구조적 서식지를 중심으로 6개 대분류로 구분하였으며, 중분류는 59개의 생태계 유형으로 분류하였다. 산림생태계는 20개, 하천 및 습지생태계는 8개, 해안생태계는 16개, 농경지는 6개, 개발지는 9개, 해양생태계는 1개로 분류하였다. 서식지 분류 체계를 기반으로 정사영상, 정밀식생도, 임상도를 활용하여 서식지 분류 지도를 작성하였다. 서식지 분류 지도는 21개 국립공원에 대해 1,461개 도엽으로 구축하였다. 본 연구의 활용성을 높이기 위해 국내 서식지 조건을 고려한 서식지 분류 체계 고도화와 조사 프로토콜을 개발하여 서식지 평가에 적용하여야 한다. This study was conducted to develop a habitat type classification system and its map based on the ecological characteristics of species, spatial type, vegetation, topography, and geological conditions preferred by species. To evaluate the relationships between species and their habitats in Korean national parks, we prepared a classification standard table for systematic classification of habitat types. This classification system divides habitats into 6 low-level and 59 mid-level ecological classes based on habitat structure. The mid-level system divided forest ecosystems into 20 subtypes, stream and wetland ecosystems into 8 types, coastal ecosystems into 7 types, arable land into 6 types, development land into 9 types, and 1 type of marine ecosystem. A habitat classification map was drawn utilizing square images, detailed vegetation maps, and forest stand maps, based on the above habitat classification system, and it covered 1,461 plots spanning 21 national parks. The habitat classification system and survey protocol, which consider domestic habitat conditions, should be further developed and applied to habitat assessment, to enhance the utility of this study.

La(Ⅲ)-impregnated mesoporous silica(La-MS) adsorbent has been developed for the removal of F and P ions by adsorption. These adsorbent have been characterized by zeta potential, XRD and SEM analysis. To elucidate the surface characteristic of adsorbent, the zeta potentials were measured. As a result of zeta potential data, mesoporous silica(MS) indicated that the surface potentials seem to be dependent on the pH and the -15∼-55㎷ showed in the range of all pH. Otherwise, the surface potentials of La-MS indicated that the +50∼-40㎷ charge at the range of all pH. La-MS was tested for the removal of F and P ions from aqueous solution. Experiments were carried out as a function of pH and anion concentration in aqueous phase. The equilibrium time was 120min and equilibrium experiment data obeyed the pseudo second order kinetic model. The Langmuir model and Temkin model represented the experimental data as well. The maximum adsorption capacity of F and P ions calculated from Langmuir isotherm model was 22.24㎎/g and 23.86㎎/g, respectively. From calculated Temkin constant(B=2.857∼3.503J/㏖), this adsorption process is physical adsorption. The mechanism of the adsorption process showed that adsorption was dependent on intra particle diffusion model according to two step diffusion. To estimated thermodynamic parameters(△H0, △S0 and △G0) indicated that the adsorption was spontaneous and endothermic. The removal selectivity by La-MS was in order by F < P.

The patent applications of air pollution abatement technology are collected and their spatial distribution is analyzed. They are classified in view of 16 regional local governments and industry classification(NACE). Especially, industry classification is matched with International Patent Classification(IPC). We find that the patent applications of air pollution abatement technology is spatially concentrated in Seoul, Kyunggi and Incheon. And regions also show some heterogeneity in the pattern of patents by industry. This means that the effect of local environmental policy can be different depending on the type of industry. If an industry is related to the export-oriented finished good production such as auto, electronic components then the patent activity is concentrated on city with research and education facilities. If an industry is domestic oriented raw material and equipment producers such as non-purposed machinery or basic chemical, the patent activity are equally spread over whole nation. When we analyze the patent applicants with Moran I`s statistics by region and the type of applicants, someweak geographical patterns can be observed.
