Abstract: In the farmland landscape, the windbreak network, as an important corridor system, plays a crucial role in conserving landscape connectivity and biodiversity. In this study, high reso-lution remote sensing images were employed to calculate the relative errors of the landscape metrics of farmland windbreaks in the existing situation and the ideal situation, and evaluate the landscape pattern of the farmland windbreaks in the Manas River Basin oasis. The result shows that, for the farmland windbreaks in Manas County, Shawan County, and the Regimental Farm, the relative errors of their landscape metrics were 0.7240, 0.7374 and 0.7579 for the ratio of belt to patch, 0.5307, 0.5629 and 0.6863 for the connectivity, and 0.6577, 0.6380 and 0.4945 for the ring degree, respectively. The relative error of each landscape metric was greater than 0.15, which indicates the farmland windbreaks in the Manas River Basin oasis cannot meet the good quality standard. The prominent problems include the limited windbreak area, uneven windbreak distribution, small number of closed grids, and poor standforming conditions. In order to achieve the sustainability of the farmlands, the missing windbreaks need to be supplemented and the density of windbreaks should also be increased.
Key words: boreal forest, model coupling, carbon storage, climate change, disturbance
