【摘要】 利用渭干河—库车河三角洲绿洲1989—2007年的遥感数据,采用ENVI4.5遥感影像处理系统对研究区3个时期的数据进行处理,同时使用ARCGIS统计分析和计算,最终得到研究区土地利用/覆盖动态变化规律,并建立数据模型,探讨其荒漠化响应趋势。研究结果表明:在人类有意识的干扰下,进行科学的生态环境建设,将有利于合理的土地利用格局的形成和对土地荒漠化的遏制。更多还原

【Abstract】 Using the remote sensing data of 1989—2007 years in the delta oasis of Weigan and Kuqa rivers,and adopting the ENVI4.5 remote sensing image processing system, the data of three periods in the study area was processed. At the same time, through the use of ARCGIS statistical analysis and calculation, the dynamic law of LUCC in study area has gotten, and the model of data established, and the response trend of desertification investigated. The results showed that under the disturbance of human consciousness, the scientific construction of ecological environment would be conducive to the rational land use pattern formation and suppression of land desertification.更多还原
