摘要：利用遥感影像数据,采用斑块密度、形状指数、聚集度指数等景观指数和景观开发强度指数、景观压力指数,分析了2004年、2010年和2016年衡水湖国家级自然保护区的景观格局、保护成效及其主要影响因素。研究结果表明,2004年、2010年和2016年衡水湖国家级自然保护区的景观格局都是西部主要为耕地和东部主要为自然湿地;随着时间的推移,林地、草地和道路的面积在明显增大,尤以草地的面积增幅最大;虽然该保护区的保护性景观面积所占比例增大,但是道路等基础设施的建设使该保护区的景观破碎化;该保护区的景观开发强度有所减弱,总体景观保护成效较好,但是自然湿地周边局部的景观开发强度增大;耕地、林地、草地、鱼塘和公园绿地面积的变化决定了2004年、2010年和2016年衡水湖国家级自然保护区保护成效的变化;耕地面积减小和林地面积增大使该保护区的景观压力减轻,自然湿地萎缩及其周边鱼塘和公园绿地面积的增大导致该保护区景观压力增大,影响了其保护湿地的成效。未来应该进一步加强对衡水湖国家级自然保护区自然湿地周边人类活动的管理和控制,充分考虑野生动植物的生境需求,禁止不必要的设施建设和园林绿化等;在保护湿地的前提下,开展湿地生态系统恢复工作。
Based on remote sensing image data,the landscape development intensity index,landscape stress index and landscape indices such as patch density,shape index and aggregation index,were used to analyze the landscape pattern,conservation efficacy and main influencing factors of Hengshui Lake National Nature Reserve in 2004,2010 and 2016.The results showed that the landscape pattern of Hengshui Lake National Nature Reserve was mainly cultivated land in the west and natural wetlands in the east in 2004,2010 and 2016.With the passage of time,the area of woodland,grassland and road increased obviously,especially the area of grassland increased the most.Although the proportion of the protected landscape area in the nature reserve increased,the landscape fragmentation was caused by the construction of roads and other infrastructure.The landscape development intensity in the nature reserve had weakened,and the overall conservation efficacy of landscape was good,but the landscape development intensity around the natural wetland had increased.The area change of cultivated land,woodland,grassland,fishpond and public park determined the change of the conservation efficacy of Hengshui Lake National Nature Reserve in 2004,2010 and 2016.The decrease of cultivated land area and the increase of woodland area reduced the landscape stress of the nature reserve,while the shrinkage of natural wetlands and increase of surrounding fishpond and public park increased the landscape stress of the nature reserve,which affected the conservation efficacy of wetlands.In the future,we should further strengthen the management and control of human activities around the natural wetland in Hengshui Lake National Nature Reserve,taking into account the habitat requirements of wildlife,and prohibiting unnecessary facilities construction and landscaping.The restoration of wetland ecosystem should be carried out on the premise of protecting wetlands.
