中文摘要	本文在地理信息系统与遥感技术的支持下,以焉耆县1993-2019年遥感影像为数据源,获取1993年、2003年、2013年、2019年4期土地利用分类数据库,应用土地利用动态度变化模型和典型的景观格局指数,对该县近27年土地利用类型变化情况和景观空间格局变化特征进行研究分析。结果表明,在研究期内,耕地、建设用地和水域面积分别增加了9810.59 hm~2、 19131.68 hm~2及829.13 hm~2,草地、林地、裸地、裸岩、沼泽地和沙漠面积分别减少了2142.83 hm~2、5448.52 hm~2、13338.32 hm~2、 1530.76 hm~2、330.76 hm~2及6980.21 hm~2。研究期末占研究区总面积比例从大到小依次为耕地(21.44%)、林地(17.51%)、沙漠(16.88%)、草地(12.33%)、建设用地(12.07%)、裸岩(11.62%)、裸地(6.54%)、水域(0.84%)及沼泽地(0.77%);而且各种斑块类型景观破碎度逐渐降低,最大斑块类型面积变化幅度不大,但景观多样性增加。研究认为:焉耆县土地利用整体处于快速发展时期,受人类活动影响景观空间格局变化明显,因此有必要采取措施加强对土地资源的保护,推动恢复当地生态环境的各项工作深入开展。
英文摘要	Based on the geographic information system and remote sensing technology, the land use classification database in 1993, 2003, 2013 and 2019 were obtained by using remote sensing images of Yanqi from 1993 to 2019, and the change of land use types in the research area in the past 27 years was analyzed with the land use dynamic change model. The results showed that during the study period, the areas of cultivated land, construction land and water area were increased by 9810.59 hm~2, 19131.68 hm~2 and 829.13 hm~2, respectively, while, the areas of grassland, woodland, bare land, bare rock, wetland and desert areas were decreased by 2142.83 hm~2, 5448.52 hm~2, 13338.32 hm~2, 1530.76 hm~2, 330.76 hm~2 and 6980.21 hm~2, respectively. At the end of the study period, the proportion of the area of land use type in total research area was decreased in the order of cultivated land (21.44%), forest land (17.51%), desert (16.88%), grassland (12.33%), construction land (12.07%), bare rocks (11.62%), bare land (6.54%), water area (0.84%) and wetland (0.77%). On this basis, the typical landscape pattern indices were selected to analyze the characteristics of landscape spatial pattern in Yanqi. The fragmentation degree of each patch type in the research area was gradually reduced in the past 27 years, while the maximum patch type area changed slightly and the landscape diversity was increased. The overall land use in Yanqi was in a rapid development period, and the landscape space pattern was significantly affected by human activities. Therefore, it is necessary to strengthen the protection and restoration of the local ecological environment.
