中文摘要	防护林网作为农田景观的重要廊道系统,对生物多样性以及景观连通性等具有至关重要的作用。本研究以新疆玛纳斯河流域为研究区,基于高分辨率遥感影像,计算现实状态与合理状态下农田防护林网景观指标的相对误差,对玛纳斯河流域绿洲农田防护林网景观格局进行评价。结果显示:玛纳斯县、沙湾县和团场的防护林网带斑比的相对误差分别为0.7240、0.7374和0.7579,连续度的相对误差分别为0.5307、0.5629和0.6863,环度值的相对误差分别为0.6577、0.6380和0.4945。各景观指标的相对误差均大于0.15,说明玛纳斯河流域绿洲农田防护林网尚且达不到优质标准,存在林带面积不足、林网分布不均匀、闭合网格较少,成型状况较差等问题。建议在防护林的建设和管理中,加强缺失林带的补齐工作,并增加林带密度,通过科学合理的防护林网空间配置实现绿洲农田的可持续发展。
英文摘要	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 resolution 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 stand-forming 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.
