| 摘 要： | 黑河流域额济纳绿洲是我国西北干旱区典型的荒漠绿洲。干旱荒漠绿洲有其自身的景观生态特点。根据地貌、水文条件状况及区域土地利用格局等因素将额济纳绿洲划分为3个景观格局分析单元即古日乃拐子湖盆区、冲积平原区、马鬃山剥蚀低山残丘区，依据景观生态特点划分出10个景观嵌块体类型。利用景观空间格局指标分析了荒漠绿洲景观格局及其变化，得出额济纳荒漠绿洲景观空间格局的基本特征，说明额济纳荒漠绿洲区生态环境退化已十分严重，必须进行维护和保护。

| Abstract: | Ejina oasis in Heihe River Basin is a typical desert-oasis of northwest arid areas in our country.The arid desert-oasis contains its landscape ecosystem characteristics.According to the physiognomy, the hydrology condition and the pattern of land utility etc., Ejina oasis is divided into three landscape pattern units, namely, the Gurinei Guaizi lake basin district, flood plain area, the low mountain district of Mazong mountain denudation and monadnock.On the base of the landscape ecosystem characteristic, ten landscape quadrats are carved up.Using the indices of landscape space patterns, the authors analyze the desert-oasis landscape patterns and its variety, and gain the basic characteristic of desert-oasis landscape space patterns of Ejina Basin, and show that the ecosystem environment deterioration of Ejina desert-oasis area is very severe.The measures of maintenance and protection should be carried out in Ejina desert-oasis. |
