Abstract

The effect of climate and landscape characteristics on hydrologic partitioning and vegetation response is analyzed in this study. After quantifying hydrologic partitioning using the Horton index, the relation between regional climate characteristics and the Horton index is investigated. In addition, using the comparison between the predictability of the Horton index with only regional climate characteristics and the predictability of the Horton index with landscape characteristics as well as regional climate characteristics, the relative contribution of landscape characteristics on hydrologic partitioning is analyzed. Finally, investigating the predictability of the aridity index and Horton index on the normalized difference vegetation index, the effect of climate and landscape characteristics on vegetation response is estimated.

본 연구에서는 기후와 지형특성에 따라 유역의 수문학적 분할과 식생이 어떠한 영향을 받는지가 분석된다. 수문학적 분할은 Horton 지수를 이용하여 정량화되며, 지역의 기후특성과 Horton 지수 사이의 관계가 탐색된다. 또한 지역 기후특성을 이용한 Horton 지수의 예측력과 지역 기후특성뿐만 아니라 지형특성을 이용한 Horton 지수의 예측력을 비교함으로써 지형특성이 수문학적 분할에 미치는 상대적인 공헌도가 분석된다. 마지막으로 정규화 식생지수에 대한 건조지수와 Horton 지수의 예측력을 살펴봄으로써, 식생반응에 대한 기후 및 지형특성의 영향이 추정된다.
