腾格里沙漠南缘古浪绿洲时空变化分析
|
摘要
以Landsat系列卫星影像为数据源,在提取古浪绿洲1988~2014年间7期边界数据的基础上,从绿洲面积变化、变化速度、趋势动态度指数、双向动态度指数、格网化变化率等方面对绿洲扩张/退缩的时空变化过程进行分析。结果表明,古浪绿洲扩张比较显著的区域主要位于腾格里沙漠南缘的景电引黄灌区、以黄花滩乡和永丰滩乡为主的井灌区以及位于西靖乡和黄花滩乡的"下山入川"生态移民项目区,古浪绿洲向北部荒漠地区蔓延的趋势比较明显。水利建设、人口增长、生态移民、生态治理以及科技进步等因素是古浪绿洲变化的主要驱动力。
Taking a series of Landsat satellite imageries as data source, based on the boundary data of Gulang oasis from 1988 to 2014, this paper analyzed the spatio-temporal variation of oasis form changes and growth rate of area, indexes of dynamic trend and two-way dynamic degree, the rate of grid change. The results show that the significant expanded regions of Gulang oasis in 26 years are located in the Jing electric–irrigation region, well irrigation region in Huanghuatan town and Yongfengtan town and the ecological migration programs region which are named "from mountain to plain" in huanghuatan town and xijing town, which are at the southern boundary area of Tengger Desert. The trend of Gulang Oasisspreading to northern Tengger Desert region is clear. The construction of the water conservancy facilities, population growth, ecological migration, the management of the ecological environment and scientific and technological progress are the main driving force for Gulang oasis variation.
