이 연구는 중국 내몽고 쿠부치사막지역의 사막화확산 방지를 위한 사막복구조림을 실시함으로써 장기적으로 사막화지역에 적합한 사방기술을 향상시키는데 기여하고자 수행하였다. 연구지역은 모래가 약 97%로 식재시 지속적인 수분공급이 필요하고, 토양pH가 7.2~7.9인 약알칼리성토양으로 토양양료가 대단히 부족한 상태로 나타났다. 우리나라 산림청이 조림한 지역에서 양수(楊樹, Populus simonii Carr.)의 평균활착률은 87.8%로 나타난 반면, 사류(沙柳, Salix gordejevaii Chang et. Skv.) 평균활착률은 76.8%로, 양수보다 저조하였다. 양수의 평균 신초생장량은 50.4 cm로 나타났고, 사류의 평균 신초생장량은 67.8 cm로 나타나 신초생장량은 사류가 양수보다 높은 것으로 나타났다. 경기도가 조림한 지역에서 양수의 평균활착률은 89.5%로 나타난 반면, 사류의 평균활착률은 68.3%로 양수보다 현저히 낮아, 보식이 필요한 것으로 나타났다. 양수의 평균 신초생장량은 56.7 cm로 나타났고, 사류의 평균 신초생장량은 56.9 cm로 나타나 두 수종 간 차이는 없는 것으로 나타났다.

This study was carried out to improve an appropriate technic of erosion control engineering in the desertification area by long-term by performing the desert afforestation for preventing the spread of desertification in Kubuqi Desert area of Inner Mongolia, China. Since the study area consists of the sand of 97%, continuous water supply for the planting is needed. In addition, this area showed to have very low nutrient because it has a slightly alkaline of a pH7.2~7.9. In afforestation area planted by Korea Forest Service, the average survival rate of Populus simonii carr was 87.8% showing that it does not require supplemental planting. In addition, the average survival rate for Salix gordejevaii chang et.skv. was low than Populus simonii Carr as 76.8%. The average shoot growth increment of Populus simonii Carr. and Salix gordejevaii chang et. Skv. was 50.4 and 67.8 cm, respectively showing that Salix gordejevaii Chang et. Skv. is higher than Populus simonii Carr. In afforestation area planted by Gyeonggi-do, the average survival rate of Populus simonii Carr. was 89.5% showing that it does not require supplemental planting. However, Salix gordejevaii chang et. Skv. showed that supplemental planting is needed because the average survival rate was very low as 68.3%. In the afforestation area planted by Gyeonggi-do, the average shoot growth increment of Populus simonii Carr. and Salix gordejevaii chang et.skv. was 56.7 cm and 56.9 cm, respectively. This result indicates that the average growth increment of Salix gordejevaii Chang et. Skv. is higher than Populus simonii Carr.
