摘　　要：开展长时序遥感生态监测对保护和修复湿地资源,推进生态文明建设具有重要意义。本研究以此为出发点,以景观生态学为理论基础,在RS和GIS技术支持下,开展了丹江口水库湿地近20年景观格局的时空变化研究,并对其驱动力进行分析,提出相关措施,以期为丹江口水库湿地的生态保护和修复及区域资源的优化利用等提供理论依据和参考建议。结果表明,1999年以来,丹江口水库湿地景观格局的空间变化度较高,草地和耕地面积大量减少,林地、水域、建设用地面积整体上呈增加趋势,其中建设用地的景观动态度最高;1999-2017年,各景观类型破碎化程度均较高且沿水域方向有增加趋势;人类活动已成为丹江口水库湿地景观格局变化的主要驱动因子。It is of great significance to carry out long-term remote sensing ecological monitoring for the protection and restoration of wetland resources and to promote the construction of ecological civilization.Taking this as a starting point,based on landscape ecology as the theoretical basis,with the support of RS and GIS technology,the research on the spatiotemporal changes of the landscape pattern of Danjiangkou Reservoir Wetland in the past 20 years was carried out,and its driving forces were analyzed and related measures were proposed,which was expected to provide theoretical basis and reference suggestions for the ecological protection and restoration of Danjiangkou Reservoir Wetland and the optimal use of regional resources.The results show that since 1999,the spatial pattern of the landscape pattern of the Danjiangkou Reservoir Wetland has been relatively high,the area of grassland and arable land has been greatly reduced,and the area of woodland,waters,and construction land has generally increased;from 1999 to 2017,the fragmentation degree of each landscape type was high and there was an increasing trend along the water area;human activities have become the main driving factors for the change in the landscape pattern of the Danjiangkou Reservoir Wetland.
