中文摘要	应用"3S"技术，通过选取景观多样性指数、优势度指数、破碎度指数、斑块形状指数等空间格局指数对准噶尔内流区1975年至2009年近三十四年间湿地景观格局变化进行研究。结果表明：近三十四年来湿地面积总体小幅度增大，其中，1975年至2000年，湿地面积小幅度增大，2000年至2009年，湿地面积小幅度减小。湿地景观多样性增大，优势度减弱，破碎度先增大而后减小，斑块形状趋于复杂，各湿地景观类型间的差异减小，湿地景观结构趋于稳定。各湿地类型中，河流湿地面积先增大而后减小；湖泊湿地面积先增大后减小；沼泽湿地变化幅度较小；人工湿地面积持续减小。准噶尔内流区湿地景观格局的变化与流域内的水资源循环相关性较强，人类活动尽管对其产生了较大干扰，但并未改变湿地整体景观格局，因而，有利的气候条件与合理的人类活动是西北内陆干旱区湿地景观稳定与发展的决定因素。
英文摘要	Using "3S" technology,we carried out research on the changes of wetland landscape pattern of the inland water of Junggar based on the diversity index,dominance index,fragment index and patch shape index from 1975 to 2009. The result showed that the wetland area overall increased modestly in the last 32 years, in which, the wetland area had increased modestly from 1975 to 2000,and the wetland area reduced modestly from 2000 -2009. The diversity of the landscape pattern increased,but the dominance index reduced, the fragment index increased firstly and then decreased, the patch shape tended to complex, the difference among all wetland types reduced, the wetland landscape structure tended to stable. In all the wetland types,the river wetland area firstly increased and then reduced ; the lake wetland area firstly increased and then reduced ; the variety range of the marsh wetland was small ; The artificial wetland area reduced continuously. The correlation was high between the changes of wetland landscape pattern and the water resource cycle in the inland water of Junggar,although the human activity had produced a greater interference,it was not change the wetland overall wetland landscape, Thus,the favorable climatic conditions and human reasonably activities are the deciding factors for stability and development of wetland landscape in Northwest arid area.
