摘要
以黄河三角洲生境分布图为基础 ,运用遥感和地理信息系统得出三个时期丹顶鹤 (Grusjaponensis)生境分布图。选取一系列的景观指数 ,通过APACK软件进行计算 ,结合土地利用动态度的概念对黄河三角洲地区 1 986～ 2 0 0 1年丹顶鹤生境的动态变化进行分析。结果表明 :适宜丹顶鹤栖息的生境面积不断减小 ,该地区的生境破碎化程度也不断升高 ;相应的适应丹顶鹤栖息的各生境类型的面积除了轻干扰深积水鱼类苇田 (人类活动造成 )的面积增加外 ,其余大多呈减少趋势 ,总的来说丹顶鹤栖息生境质量呈下降趋势。
Based on the Yellow River delta habitat map, the Red-crowned Crane suitable habitat map was developed by RS and GIS. Based on a series of selected landscape indices, this paper analyzed change of habitat suitable for the Red-crowned Crane in Yellow River delta from 1986 to 2001. The results show that suitable habitat for the species is decreasing and there is an increased fragmentation. Areas of all types of habitats are decreasing except those with less intensive human disturbance deep seeper, sufficient fish and high and dense vegetation.In short, the quality of suitable habitat for the Red crowned Crane is deteriorating mostly owning to the disturbance of human beings.
