| 中文摘要 | 干旱区内陆河及尾间湖泊构成了完整的生态体系，沿河流分布的人工绿洲，是人类通过土地资源开发，重新配置水资源时空分布的重要区域。人类活动和自然因素影响下的河径流变化，不仅反映了人类的水土开发过程，并进一步影响到河流，湖泊生态系统，使之产生一系列的响应。艾比湖，古称\ |
| 英文摘要 | Because of water and soil exploiture of humankind in arid region, landscape pattern's time and space ordonnance, transform and distribution of water resource changed a lot. Aiby lake, located in west-southern part of Junggar basin of Xinjiang arid region, Ala mountain pass in it west-north direction, is the biggest salty lake of Xinjiang. Because of low hypsography, the lake became the influx center of river and salt.From start of 1950s to the end of 1970s, the lake area varied from sharply shrink to gradually stabilization because of human large-scale immoderate water and soil exploiture. The ecological environment faced serious crisis of Aiby basin, which thread oasis around, and endanger the sustainable economics development of northern piedmont of Tianshan Mountain. Since end of 1970s to end of 1990s, especially end of 1990s, the lake area Is enlarged because of the increase of rainfall. Surrounding ecological environment renewed at the same time. But people continue enlarging the exploiture scale of water and soil, and oasis land degenerated a lot in middle and lower reaches of Jinghe river.Jinghe river is one of important water-supporting rivers of Aiby lake with length of 114km. The river consist of different landscape patterns, such as mountain, oasis and desert, which are the mainly landscape units of arid region river. In the middle reaches of Jinghe river, distributed oasis ecological systems, which are quad landscapes basing on the matrix of Gobi and desert, with the shape of distributing patches. Under effort of mankind activities, climate condition, the otherness of water resource distributing, soil condition, and many kinds of social factors, landscape pattern of the region has more heterogeneity and evolvement. The paper work on the research of Jinghe river1 basin system under using Landscape Ecology theory, typical time remote sense images, relief maps, soil and vegetation data. And, analysis the evolvement laws (direction and stagger) influencing nature factors of the basin recent 20 years.And through interpretation of satellite maps, GIS space analysis and landscape index statistic, the paper made completely analysis of different landscapes variety for recent 20 years. Then ecological landscape pattern variety was investigated, which made by mankind's water and soil exploiture. Ecological factors responses was also analyzed, which means much to reasonable use of arid soil, estimate of ecological environment and landscape design. |
