Abstract

The purpose of this study is to investigate the cause of increasing dry zones through analyzing relationships between land cover and Vegetation Temperature Condition Index(VTCI) using Landsat 4-5 TM satellite images in Central Dry Zones of Myanmar. As a result of land cover classifications, while vegetation areas gradually decrease, residential area and cropland were increased. VTCI analysis shows that region (a) showed a gradual decrease in the area of severely arid, and increase in the area of moderate dry and wet, which sums up to a slight decrease in aridity. Region (b) also showed to increase in dry areas and severe aridity. The result of relational analysis between VTCI and land cover change showed high ratio of land cover change, from severe arid area to forest and residential farmland. The average VTCI decreased in the changed land covers, which indicates the relationship between aridity and land cover change and a gradual increase in the arid area was identified.

본 연구에서는 미얀마 내 Mandalay, Magway 지역에 대해 Landsat 4-5 TM 위성영상을 이용하여 토지피복 변화와 식생온도조건지수(Vegetation Temperature Condition Index; VTCI)의 관계를 분석함으로써, 미얀마 토지피복 변화와 건조 정도의 관계를 밝히고자 하였다. 토지피복 변화를 분석한 결과, 연구 대상 지역에서 산림은 감소하는 것으로 나타난 반면, 주거지와 농경지의 면적은 증가하였다. VTCI 분석을 수행한 결과, (a)지역에서는 매우 건조한 지역의 면적이 점차 감소하고, 건조한 지역 및 보통, 습윤한 지역의 면적이 증가하여 건조의 정도가 다소 감소되는 것으로 나타났다. (b)지역 또한 매우 건조한 지역의 면적이 증가하여 건조 정도가 심각해지는 것을 파악할 수 있었다. VTCI와 토지피복 변화의 관계 분석결과는 두 지역의 매우 건조한 지역에서 산림 및 주거지의 농경지로의 변화 비율이 비교적 높게 나타나고, 변화된 지역의 VTCI 평균이 감소하여 토지피복의 변화와 건조 정도의 변화의 관련성을 찾을 수 있었으며, 건조지역이 점차 증가하고 있음을 확인하였다.
