수요증가가 예상되는 겨우살이의 인공번식을 위한 기초자료로 활용하고자 겨우살이의 분포지역의 기주수종과 서식지 환경을 조사하여 분석하였다. 겨우살이의 자생지는 전국에 분포하고 있었으며, 기주식물로는 졸참나무와 같은 참나무류가 대부분이였고 밤나무, 벚나무, 오리나무, 돌배나무 등에서 볼 수 있었다. 군락지의 같이 자생하는 침엽수인 소나무, 잣나무와 활엽수인 느티나무, 감나무, 고로쇠나무, 단풍나무, 뽕나무, 은행나무에서는 관찰되지 않았다. 자생지의 고도는 해발 0~1200 m까지 잘 생육되고 방향과 지형을 가리지 않고 기주식물이 잘 생육 할 수 있는 곳이면 전국에서 재배가 가능할 것으로 판단되었으며, 종자 전파는 조류에 의함이 확인할 수 있었다. 겨우살이의 기생은 흡기 발생부터 기주식물의 표피 또는 조직성분에 따라 영향이 있을 것으로 생각되며 인공재배 연구의 좋은 성과를 위해 겨우살이가 잘 기생하는 기주식물의 기주 특이성에 대한 연구가 이루어져야 할 것으로 사료된다.

This study has been conducted to perform the survey on the ecological systems, scenary, and water quality change for agriculturally purposed drainage channels constructed with the application of environment-friendly methods and thus to evaluate the environment-friendly redevelopment effects of them. The main results of this study are as follow: 1. The channels not looking good aesthetically before redevelopment had changed into graceful scenic views from the aspect of landscape architecture as natural-type gently waterside to the channel and naturally-looking water stream. In the village parks developed for the rest of residents, an enough view was secured and thus a wide prospect scope could be obtained. 2. The flora in the channels have increased to 35 families and 82 species from 19 families and 32 species before renovation. As the growth speed of them are slower than externally-brought plants, they can cause some risks to the stability of land slope, including scour by erosion. From that reason, it is necessary to adequately combine the species of the plants both natively growing there and externally-brought planted. 3. In case of water quality, it turned out that, from more than a year after redevelopment, plants began to take roots and the water quality improved. On the contrary, there have been some cases, partly found, that aggravated the quality of water due to the causes like as retention of floating matters by withered plants or plant bodies after the growth of plants in the channels under survey became active, and therefore it is judged that a periodic maintenance of waterways is needed. 4. In case of fishes, all species before renovation have revived, and the population and the number of species have increased after works the formation of puddles in the channels. In waterside grasslands, amphibia and reptiles have not only increased but also been diversified.

수종간 독립성 검정결과 상수리-산초나무 외에는 지역별로 유의한 종간 상관이 서로 다르게 나타남으로써 수종간 생태적 지위의 공유관계는 수종간의 친화력뿐만 아니라 생육환경에 의한 영향도 큰 것으로 해석된다. 환경요인을 독립변수로 한 군집분석결과 물푸레나무는 화살나무, 노간주나무, 떡갈나무, 산초나무, 개옻나무 등과 같은 집단(물푸레나무-개옻나무 그룹)으로 분류되었으며, 음나무는 느릅나무, 당단풍, 병꽃나무, 물갬나무 등(음나무-느릅나무 그룹)과, 고로쇠나무는 두릅나무, 거제수나무, 서어나무 등과 같은 집단(고로쇠나무-거제수나무 그룹)으로 분류되었다. 환경요인과 군집간의 상관분석결과 지형, 해발고, 사면방향, 경사, 출현종수 등의 환경요인 중 지형과 해발고에 따른 영향을 많이 받는 것으로 분석되었다. 고로쇠나무-거제수나무 그룹은 해발고가 높은 계곡부~사면하부에 주로 분포하는 것으로 나타났으며, 음나무-느릅나무 그룹과 물푸레나무-개옻나무 그룹 수종들은 지형적인 적응력이 높아 넓은 면적에 산발적으로 분포하는 것으로 분석되었다.

The objective of this study was to identify ecological environment elements that may be introduced in creating urban apartment complexes and to suggest possible options on how to introduce them. To this end, a questionnaire survey has been mailed to 120 residents-to-be of apartment complexes to suggest ecological environment elements and techniques preferred by residents-to-be and, accordingly, they have been applied to study areas. The detailed results of this study are as follows. (1) Introduction of diverse plant species instead of plantation using grasses only and considering the height and density of planting adequately appeared effective in enhancing ecological diversity as well as visual preference. (2) Creation of eco-ponds using rainwater was one of the most desirable options in urban apartment residential complexes. Also, eco-ponds can increase visual preference when they are arranged through adequate vegetation management. (3) The results showed that when creating habitats for such as insects using porous space, it is desirable to consider a visual aspect first and then to create habitats for various insects. When the results of this study are actually applied to a real study area, it will be able to increase ecological diversity in urban apartment complexes as well as raising visual preference. Accordingly, it should be introduced proactively in planning, designing, and creating real apartment complexes.

The objective of this study is to propose the whole idealistical process for ecological area zoning based on the natural environment analysis. In order to draw out the ecological zoning, this study used the remote sensing, GIS method and field survey. As a result of this study showed that it was helpful in establishing development direction of Midong Mountain, minimizing the impact on environment by drawing out a development suitable land based on the objective standards and data and also preventing the misconduct development in advance.

붉은대극의 생태를 조사한 결과 이 식물의 개화 및 결실기인 4~5월에 상대조도 16~49%의 계곡에서 잘 자라는 것을 알 수 있었다. 이식실험 결과 이 식물은 직사광선을 거의 받지 못하여도 상대조도 10% 이상에서는 개화가 가능하나, 결실을 위해서는 최소한 1시간 이상의 가조시간이 필요함을 알 수 있었다. 또한 잎이나 뿌리의 형태 등은 생육환경에 의해 좌우되었으나, 자방 및 총포 내의 털은 유전적으로 고정된 형질로 관찰되었다.
