We examined the nutrient dynamics during the leaf litter decomposition rate and process of Pinus rigida and Pinus koraiensis in Gongju for 21 months from December 2014 to September 2016 as a part of National Long-Term Ecological Research Program in Korea. The remaining weight rate of P. rigida and P...

산림생태계의 구조와 기능은 무엇을 통해 유지되는가? | 산림생태계의 구조와 기능은 에너지 흐름과 영양염류 순환을 통해 유지되는데, 에너지와 영양염류를 모두 포함하고 있는 낙엽의 생산과 분해에 관한 연구는 생태계의 기 능을 이해하기 위한 기본적인 과정이다(Bray and Gorham, 1964; Berg and Agren, 1984; Berg et al,. 1987). | |
낙엽의 분해는 생태계 내의 어떤 역할을 하는가? | 2008). 낙엽의 분해는 산림생태계 내의 물질순환에서 가장 기본적인 과정이라 할 수 있으며, 유기물 분해를 통한 영양염류 방출은 식물 생장에 필요한 영양염류 공급원이기 때문에 생태계 구조와 기능을 결정하는 중요한 요인이 된다(Berg and Agren 1984, Berg and Theander 1984, Kelly and Beauchamp 1987). 낙엽 분해에 영향을 주는 낙엽의 화학성분 중 중요한 것은 초기의 리그닌, 질소 그리고 인의 함량이다. | |
영양염류의 양과 낙엽의 분해량을 조사하는 이 연구의 목적은 무엇인가? | 본 연구는 우리나라 조림지 삼림에 이용되는 잣나무와 리기다소나무를 대상으로 영양염류의 양과 낙엽의 분해량 을 조사하기 위해 공주시 신관동 호태산의 리기다소나무조 림지에 리기다소나무와 잣나무 낙엽주머니를 설치하고 2014년 12월부터 2016년 9월까지 3개월 간격으로 낙엽주머니를 수거하여 분해율 및 분해과정에 따른 영양염류의 동태를 조사하였다. 주요 조림수종 낙엽의 분해를 통해 토양에 이입되는 영양염류의 양을 파악하여 삼림 생태계의 물질순환을 밝히는 데 필요한 기초 자료를 얻는데 본 연구의 목적이 있다. |
