초록

황사의 발원지인 중국의 사막화는 과도한 경지개간과 산업화 등으로 인해 계속해서 심각해지고 있으며, 이로 인해 국내의 황사 피해 역시 증가하고 있다. 중국에서 발생하는 황사는 중국 자국 뿐만 아니라 인접 국가에도 영향을 미치기 때문에 국제적인 문제가 되고 있으며 중국은 국제사회의 지원을 받으며 황사의 원인인 사막화를 막기 위한 조림사업을 시행하고 있다. 그러나 이러한 조림사업에 대한 확인은 중국 통계청에서 작성한 조림 성과 보고서를 통해서만 가능하여 공여국에서 조림 사업의 성과를 실질적으로 파악하는 데에 한계가 있다. 이에 본 연구에서는 중국의 조림사업이 꾸준히 진행되어 온 중국 산시성 위린 지역을 대상으로 원격탐측 방법을 이용하여 중국 조림 현황에 대한 모니터링을 수행하고자 하였다. 원격탐측 자료로는 MODIS 영상이 사용되었으며, 식생지수를 통해 2000년부터 2014년까지 식생이 증가함을 확인할 수 있었고, 추정된 조림면적이 실측 자료와 일치하는 경향을 보이는 것으로 확인되었다.

Desertification in China, one of the source regions of yellow dust, has been worsen by industrialization and extreme land development, which increases the damage caused by yellow dust in Korea. Because the yellow dust from China affects not only their own country, but also neighboring countries, it is becoming an international problem, and China has been started afforestation projects to prevent excessive desertification with the help of the international community. However, it is only possible for identifying the results of afforestation projects to check afforestation result reports from National Bureau of Statistics of China, which makes it difficult to check out tangible results. Therefore, this study was conducted by using remote sensing technique for monitoring afforestation status of Yulin, shaanxi, China. in which an afforestation project has been carried out steadily. MODIS imagery was used as remote sensing data and it was confirmed that vegetation has been increased through vegetation indices from 2000 to 2014 and afforestation areas were estimated as same trend of ground reference data.
