This paper has obtained the following results by investigating the physical geographical names appeared on the school songs of the primary secondary school in Daegu metropolitan city. 1) The physical geographical names appeared many on the school songs in the old-established schools are the traditional physical geographical names such as The Mt. Palgong, The Geumho river, The Nakdong river, The Mt. Biseul and the physical geographical names related to the identity of Daegu such as Dalgubeol, The Mt. Taebaek, Seorabeol and so forth. 2) The physical geographical names appeared many on the school songs in the primary schools are The Mt. Palgong, The Geumho river, The Nakdong river, and The Mt. Biseul in order, while those appeared many on the school songs in the secondary schools are The Mt. Palgong, The Geumho river, The Nakdong river, and The Mt. Biseul in order. 3) Since The Mt. Taebaek and Seorabeol relatively often appear in the physical geographical names, we can find the relationship between Daegu and Silla Dynasty, and that between The Mt. Palgong and The Mt. Taebaek from the viewpoint of feng shui. 4) In case of the school songs in the schools distributed around the area of Suseong-Gu and DalSeo-Gu which are newly developed, the physical geographical names within the two areas in addition to the traditional physical geographical names(including the physical geographical names related to the identity of Daegu) appeared many on the school songs. 5) The Mt. Palgong, which is the representative physical geographical name of Daegu, almost did not appear on the school songs of the schools within the Dalseong-Gun. In other words, the residents in the Dalseong-Gun have recognized the mountain based on The Mt. Biseul rather than The Mt. Palgong. 6) It is special that The Sincheon amounting to the central stream in Daegu almost did not appear on the school songs. 7) It is concluded that the physical geographical names found in this paper can be not only set as main ecological space in Daegu area but also considered in top priority as ecological space in the various plans of development.

This study was carried out to find growth increasing methods of Rhododendron mucronulatum in Mt. Biseul. 4 treatments(heavy pruning, light pruning, non-pruning+fertilization, non-pruning(control)) were used in the study area with different pruning methods. Growth characteristics of new shoot, number of creation of flower buds and leaf buds in new shoot were analysed. Significant differences were observed among the treatments and stem diameter degree. Diameter, length of new shoots and the number of flower buds, leaf buds per new shoots increased in the pruning treatments. But heavy pruning showed more effective growth increasing way than light pruning. Non-pruning and fertilization treatments were not effective to increase growth of Rhododendron mucronulatum. And pruning at the end of May was the most effective way for growth of new shoot.

The fish fauna and community structure at 20 stations in streams of the Mt. Biseul were investigated from June 2003 to May 2004. During the study period, 29 species, 25 genera belonging to 9 families were collected. Cyprinid fish occupied 48.3% (14 species) and cobitid fish had 13.8% (4 species). Six species (22.2%) were korean endemic and two species of Micropterus salmoides and Lepomis macrochirus were exotic. It was found that the population density of carnivorous fish (Opsariichthys uncirostris amurensis) increased in the lower-reach of small streams in the Mt. Biseul area since it had been introduced from the other native rivers in the middle 1990s. As the result of analyzing fish community in the surveyed area, the species diversity ranged from 0.553 to 1.023. The findings showed that the Geumpo, Chacheon and Hyeonpung streams had higher species diversity indicies of 0.936 ${\sim}$ 1.023 than the Sincheon and Gisegok streams with 0.553 ${\sim}$ 0.727.

This study was carried out to investigate vegetation of Rhododendron mucronulatum habitat in Mt. Biseul to recommend basic information for synecological characteristics and management methods. The survey was carried out from May to July, 2011 and totally 46 vegetation data including 42 families 93 genera 108 species 16 varieties and 5 forma were collected and analyzed. Among the investigated 129 taxa, the numbers of rare plant resources were summarized as 19 taxa; The rare plants designated by Korea Forest Service, the specific plants by floristic region and the endemic plants were listed as 3 taxa, 15 taxa and 4 taxa, respectively. Rhododendron mucronulatum habitat of Mt. Biseul was classified into 3 plant communities (Carex lanceolata-Rhododendron mucronulatum community, Potentilla dickinsii-Selaginella rossii community, Carex lanceolata-Quercus mongolica community). Carex lanceolata-Rhododendron mucronulatum community was subdivided into Tripterygium regelii subunit and Miscanthus sinensis for. purpurascens subunit by human interference degree. And synecology, syndynamics, synchorology of these plant communities were identified, and Site-species ordination analysis by Principal Coordinate Analysis (PCoA) reflected that human impact, soil moisture condition were main ecological factors determining the distribution pattern of classified plant communities. Therefore these plant communities correspond to quite distinctive 4 habitat types : unstable-dry type=Miscanthus sinensis for. purpurascens subunit, unstable-moderate type=Tripterygium regelii subunit, stable-dry type=Potentilla dickinsii-Selaginella rossii community, stable-moderate type=Carex lanceolata-Quercus mongolica community. Finally, through the vegetational diagnosis, proper management methods such as a limit on the access of visitors, planting of native woody plants after removing unwanted vines or grass were suggested.

This study was carried out to investigate the flora of Mt. Biseul. The vascular plants collected 10 times(from May 2006 to October 2007) were identified as 468 taxa in total, including 89 families, 302 genera, 397 species, 1 subspecies, 59 varieties and 11 forms. Korean endemic plants of this area were identified as 17 taxa including Thalictrum uchiyamai, Coreanomecon hylomeconoides, Lonicera subsessilis, etc.; the Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as one taxon including Aconitum austrokoreense; the Office of Forestry-designated rare & endangered plants were identified as 6 taxa including Viola albida, Lloydia triflora, Streptopus ovalis, etc.; the naturalized plants were identified as 34 taxa, and their naturalization ratio and urban index were found to be 7.3%, and 12.2% respectively. This study newly identified about 160 taxa of the plants, among which 17 taxa were newly added to the list of naturalized plants, such as Phytolacca americana, Dicentra spectabilis, Lepidium apetalum, Medicago lupulina, Euphorbia supina, Ambrosia artemisiifolia, Cosmos bipinnatus, Crassocephalum crepidioides, Galinsoga ciliata, Rudbeckia bicolor, Sonchus oleraceus, Tagetes minuta, Taraxacum officinale, Chloris virgata, Festuca arundinacea, Lolium perenne, Tradescantia reflexa, etc. There existed many kinds of plants resources having conservational value like Aconitum austrokoreense etc. in this area, but there remains a fear of nature destruction's acceleration due to indiscriminate human development and access of a lot of visitors, so it is judged that there should be a management plan, such as a limit on the number of visitors or rest-year-system for restoration of nature.

Many studies which assessed the function of forest are focused on usage of citizen, but studies which focused on natural-ecological function still lack. Hence, the purpose of this study is to select and apply the evaluation indicators on natural-ecological function of forest as a base research for sustainable planing and management. First, the 35 indicators were selected by the review of the internal and external 56 literature. The 12 indicators among those were reselected as natural-ecological indicator by the first survey and 7 indicators such as green area, connectivity etc. were determined through MCB analysis by the second survey. Also, the weights of 7 indicators for the functional evaluation were computed using AHP analysis by the third survey. As aresult of AHP analysis, the naturality was showed the highest indicator by 0.189, while the NDVI was evaluated the lowest indicator by 0.063. According to the result of evaluating the natural-ecological function on forest in Daegu which was selected as suitable study area, the natural-ecological functions around the Mt. Ap and Mt. Chengryong, top of Mt. Biseul had more than 85 scores, so those were assessed as an excellent area. On the other hand, the functions around the western area of Mt. Waryong and Mt. Macheon, the Mt. Daeni of Dalseong-Gun had less than 50 scores, which means that the area had to be controled by sustainable management. Therefore, we will be able to utilize the basic data for the preservation and management at urban and environmental planning through the results of this study.

A study on a method to overcome the limitations of the topographical and hydrological observation environment for estimating the QPE with high consistency with the ground rainfall by utilizing the spatiotemporal observation advantages of the rainfall radar for use in flood forecasting, and quantitative observations of localized rainfall due to these limiting conditions Uncertainty should be identified in terms of flood analysis. Against this background, in this study, 22 major heavy rain events in 2016 were analyzed for each of Mt. Biseul (BSL), Mt. Sobaek (SBS), Mt. Gari (GRS), Mt. Mohu (MHS), and Mt. Seodae (SDS) to determine the observation distance and altitude. The uncertainty of observation was quantified and an error map was derived. As a result of the analysis, it was found that, on average, the rainfall radar exceeded 10% up to 100 km and 30% over 150 km. Based on the average radar operating altitude angle, it was found that the error for the altitude was approximately 10% or less up to the second altitude angle, 20% at the third or higher altitude angle, and more than 50% at the fourth altitude angle or higher.

The purpose of this study is to establish the evaluation model through the systematic process of selecting the indicators and to evaluate the environmental-control function on forest using GIS in Deagu for the sustainable forest planning. The 35 indicators as basic items were selected by literature review and those were squeezed into the 29 indicators through expert brainstorming. Also, the 8 indicators to evaluate environmental-control function were selected by the first survey and the 5 final indicators such as carbon sink, temperature decrease, wind formation, water circulation, air purification were determined by MCB analysis using the second survey. The evaluation model was established through the weight of each indicator by AHP analysis using the third survey. According to the result of evaluating the environmental-control function on forest, the functions around the top area of Mt. Ap, Mt. Biseul, Mt. Palgong had more than 66 scores. On the other hand, the functions around Mt. Waryong and forest of Chilgok in Buk-gu had less than 40 scores. It is necessary to improve the function through the sustainable restoration and management in case of forest that the environmental-control function was lower. Furthermore, these results will be able to be utilized as basic data in order to establish the preservation area and control development area at the urban, environmental, and forest planning.
