我最初接触胡杨、亲近胡杨，是在额济纳。１９９０年６月，我没有去额济纳以前，曾购买了这个地区五万分之一的地形图。这种地形图相当详细，除了河流、湖泊、山峰以外，树林、灌丛、沙丘都有明显的标注。在地形图上，有许多梧桐的标记。俗语有“没有梧桐树，招不了凤凰来”之 My first contact with Populus, near Populus, is in Ejin. In June 1990, before I went to Ejin, I had purchased a one-50,000th topographic map of the area. This topographic map is quite detailed, except for rivers, lakes, mountains, forests, shrubs, dunes have obvious signs. On the topographic map, there are many sycamore markers. As the saying goes “there is no plane tree, Phoenix can not get it”
