| 摘 要： | 干旱荒漠区引水工程上水后,将原先的大片固定沙地和旱耕地转变为水浇地,并形成了新的绿洲。灌溉所涉及的区域由于有了水,生态环境得到巨大的改变,更适宜于人类居住与生存。在新绿洲的外围沙区,其生态环境总体上处于退化状态,自然因子是它变化的决定性因素。

| Abstract: | Through transferring water to arid-desert region, it formed a new oasis, that many irrigation farmland came from early fixed sand dune and no-irrigation farmland. Because of water, the environment of irrigated area varied largely, and it was becoming to exist and inhabit by human being. The sandy district surrounding new oasis, its environment is retrogressed as a whole, and that determinant variety index is nature factor. |
