调查区域位于临泽站北部，原为连片的流动沙地，其沙垄为北北东-南南西走向。在上世纪 70年代集中治理后，经20余年多种方式的人为影响，其沙垄边缘已基本固定，垄间低地有较多的植被斑块，而沙垄顶部和较大落沙坡则多为裸露。调查样带起始点位于N39°21'11.1\"，E100907'43.8\"。样带总长度600m，宽度100m。", "ds_source": "
从起始点起，用测绳沿正东方向逐段延伸，为样带主线(中心线)。沿主线每10m 处向南向北分别做1条与主线垂直的副线(记录线)，对副线东(E)、西(W)两侧的植被斑块进行调查登记。", "ds_process_way": "

The survey area is located at the north of the Linze Station. Originally a continuous expanse of mobile sand dunes, the sand ridges exhibit a NNE-SSW orientation. Following intensive control measures implemented in the 1970s and over two decades of various anthropogenic influences, the edges of these sand ridges have become largely stabilized. The interdune lowlands now support numerous vegetation patches, while the crests of the ridges and the larger slip faces remain predominantly bare. The starting point of the survey transect is situated to the north-northwest of Linze Station, at coordinates 39°21'11.1\" N, 100°07'43.8\" E. The total dimensions of the transect are 600 m in length and 100 m in width.", "ds_time_res": "", "ds_acq_place": "Linze, Zhangye City, Gansu Province", "ds_space_res": "", "ds_projection": "", "ds_process_way": "
