查询词典 dune sand

The changing trend was induced by area fluctuation of semi-mobile and semi-fixed dunes because 2.6% area of semi-mobile dunes and 12.3% area of semi-fixed dunes were unchangeable during 1987 to 1995. And, most changeable area of the semi-mobile and the semi-fixed dunes transferred to other sand-dune types and cropland.

沙漠化程度的变换主要是由半流动和半固定沙丘的变化所导致，其中在1987-1995年期间，半流动和半固定沙丘分别只有2.6%和12.3%保持不变，其余部分主要转移成其他沙丘类型和农田。

The Tuareg, turbaned nomads who for centuries have ruled this barren realm, refer to it as a "desert within a desert"—a California-size ocean of sand and rock, where a single massive dune might stretch a hundred miles, and the combination of 120-degree heat and inexorable winds can wick the water from a human body in less than a day.

Base on comparison with the remote sensing data in 1982 and 2000 and field investigation, the results of land cover and land use change were obtained by the method of landscape analysis. Ten types of land use were identified: riparian woods, riparian shrubbery, desert shrubbery, desert grassland, river-way and water area, salinised land, town, Gobi, shift sand dune, denudative upland. The results show that,(1) there were obvious changes in land cover structure.

根据黑河下游额济纳绿洲土地生态分类，利用1982年与2000年2期TM遥感数据对比和野外实地调查，采用景观生态空间分布格局分析方法，分为河岸乔木林、河岸灌草林、荒漠稀疏灌丛、荒漠稀疏草地、河道与水域、盐碱化土地、城镇、戈壁、流动沙丘和剥蚀地山丘陵，从各类土地分布面积变化和类型转移趋向与幅度两个方面，分析了额济纳绿洲20年来土地覆被变化。
