Abstract

This study was conducted to find out the methodology of carbon budget assessment among soil, atmosphere and plant. Soil respiration, net ecosystem productivity of herbs and net ecosystem productivity of woody plants have been measured in 30 years old pear orchard at Naju. Closed Dynamic Chamber (CDC) method was used to measure soil respiration and net ecosystem productivity of herbs. Net ecosystem productivity of woody plant (pear) was determined by eddy covariance method using the EddyPro (5.2.1) program. As for soil respiration, $429.1mgCO_2m^{-2}h^{-1}$ was released to atmosphere and sensitivity of soil temperature ($Q_{10}$) was 2.3. In case of herbs, respiration was superior to photosynthesis during measurement period. From 20 to 24 Jun 2015, the sum of absorbed and released $CO_2$ by herb's photosynthesis and respiration was $156.1mgCO_2m^{-2}h^{-1}$. Woody plants showed the $680.1mgCO_2m^{-2}h^{-1}$ of absorption by photosynthesis. In a farm scale, the sum of soil respiration, and net ecosystem productivity of herbs and woody plants was $0.04tonCO_2ha^{-1}$ during the measurement period, and it showed that pear orchard act as a $CO_2$ sink. This study using various approaches is expected to present a methodology for evaluating the carbon budget of perennial woody crop plantations.

본 연구는 IPCC (2006)의 농업분야 온실가스 배출권 측정의 새로운 지침에 의거하여 과수와 토양, 대기 간의 탄소수지 산정 방법론을 제시하고자 전남 나주시의 배 재배농가를 대상으로 토양 호흡량과 초본류, 그리고 과수의 생태계 순생산량을 측정하였다. 토양 호흡량 및 초본류 생태계 순생산량은 Closed Dynamic Chamber (CDC) 방법으로 측정하였고, 배 과수의 생태계 순생산량은 EddyPro 5.2.1 프로그램을 이용하여 공분산법으로 측정하였다. 배 과수원의 토양 호흡량으로 연간 $429.1mgCO_2m^{-2}h^{-1}$이 배출되었으며, 토양온도민감도 ($Q_{10}$)는 2.3으로 나타났다. 초본류의 경우 측정기간 동안 호흡이 광합성보다 우세하게 나타났다. 2015년 6월 20일부터 24일까지 초본류의 광합성 또는 호흡을 통해 흡수 및 배출된 $CO_2$의 총합은 $156.1mgCO_2m^{-2}h^{-1}$으로 상대적으로 호흡이 더 많았던 것으로 나타났다. 배 과수의 광합성 또는 호흡에 의한 $CO_2$ 총합은 $-680.1mgCO_2m^{-2}h^{-1}$로 광합성에 의해 $CO_2$가 흡수되었다. 배 과원 단위의 토양 호흡량과 초본류 및 배 과수의 광합성 및 호흡량의 총합은 $-0.04tonCO_2ha^{-1}$로 $CO_2$의 흡수원이었다. 결론적으로 배 과원에서의 다양한 접근방법을 통한 향후 다년생 목본 작물 재배지에서의 탄소수지 산정 방법론 제시에 꼭 필요하다고 판단된다.
