| 摘 要： | 选用两期遥感影像,采用室内解译结合相关调查资料进行修正的方法,获得了新疆自治区巴楚县土地利用数据库。分析结果表明,自2004年以来,巴楚县耕地面积在时间上经历了持续扩大的变化过程,在空间上呈现出以原有耕地为基础逐步向林地和草地扩张的态势。土地开垦破坏了区域内维系绿洲生态安全的防护林体系,加剧了土地荒漠化发展趋势,对生物多样性构成威胁。同时,耕地面积的不断增加,使得原本存在的水资源短缺的矛盾更加突出。

| Abstract: | The landuse database of Bachu County in Xinjiang Uygur Autonomous Region are obtained from remote sensing images of two periods by using the interpretation method combined with correlated census data for correction.Results show that cropland in Bachu County has continuously expanded since 2004 and the reclaimed land gradually spreads into forestland and grassland.Land reclamation damages the shelter forest system that protects the ecological safety of oasis,aggravates land desertification trend,and threatens local biodiversity.Meanwhile,large-scale farmland reclamation exacerbates water shortage. |
