  • A recent rise in mean global temperatures suggests a shift in the temporal cycles of natural seasons. The impacts of warming trends can alter the temporal and spatial distribution of flora and fauna. Especially, phenological cycles are very sensitive to the occurrence of alternation of hot and cold seasons. Phenological calendars reflect the natural seasonality. In more detail, phenological cycles affects agriculture and human health (i.e. the amount of fruit production and allergies), as well as tourism industries like flower fairs or festivals. (omitted)

  • 전통적으로, 토양은 식생의 분포를 결정짓는 중요한 변수로서, 생태 시스템의 보존과 관리를 위해서는 토양의 성질과 그 공간적 분포에 대한 이해가 선행되어야 한다고 알려져 왔다. 특히, 기질(substrate)이 사질 입자로 구성된 해안사구 생태 시스템은 영양소의 자체적인 생산이 충분하지 못하므로, 외부로부터 유입되는 영양소가 식생의 진입과 서식을 위한 필수적인 요소이다. (중략)

  • 나자식물은 구과목(Coniferales), 주목목(Taxales) 그리고 은행목(Ginkgoales)이 있으며 바늘잎을 가져 흔히 침엽수로 알려졌다. 국제자연보호연맹(IUCN)의 침엽수전문가그룹에 따르면 지구상에 살아있는 구과목과 주목목의 침엽수는 8과 68속의 600여종에 이르며 송백류로 부른다. 남한 면적의 67%에 이르는 660만ha에 삼림 중 침엽수림은 273만ha(42.4%), 침엽수와 활엽수 혼합림은 185만ha(28.8%)로 활엽수의 168만 ha(26.0%)에 비해 훨씬 넓지만 침엽수에 대한 관심은 적다.

  • It is important to assess the change of water environment in the present and past. In this study, present-day water quality standards are applied to the expressions in literary works to reconstruct the historical water environment including the quality. As the result, the historical reconstruction of water quality has been made distribution of water quality from 1905 to 1935 for the Sumida River in Tokyo.

  • The purpose of this study is to examine the property of climatological environment using the daily mean meteorological data measured at the serveral meteorological observatory for 30years(1961~1990). It was found that the distribution of discomfort index tended to mainly depend on the geographical situation in the same season. Major portions of Korea were subjected to continental except for some seaside districts. The discomfort index have a large(small) value in summer(winter) season. And there is a short interval(1 or 2 months) between summer and winter season in Korea.
