摘　　要：为了加强自然保护地的保护,防止保护地"孤岛"现象,基于1995年—2015年土地利用数据,以洪湖国家级自然保护区及其外围20 km区域为研究范围,利用景观指数、人工景观干扰指数、空间近邻效应评估模型等方法,定量分析洪湖自然保护区的景观动态及空间近邻效应。结果表明:①1995年—2015年,洪湖自然保护区内人工景观面积占比由9.26%减少为8.95%,自然景观面积呈增加趋势,说明保护区得到了良好保护,但人工景观干扰指数呈增加趋势,由4.02%增加为4.93%,人类开发建设活动对保护区的影响在不断加深。②保护区外围区域以人工景观为主,面积占比由82.75%增加为82.97%,而自然景观面积不断减少;人工景观干扰指数由26.13%增加为28.87%,远高于自然保护区内部。③洪湖自然保护区存在空间近邻效应,主要影响区为距保护区边界4 km的范围。研究认为在加强自然保护区内部人类活动管控的同时,必须重视保护区外围近邻区域景观动态,制定科学管控措施以减少不必要的开发建设和人为干扰。In order to strengthen the protection of the natural reserves,and prevent the phenomenon of "isolated island" in the protected area,the landscape dynamics and space neighborhood effects of the Honghu Lake Nature Reserve were quantitatively analyzed based on the land use data from 1995 to 2015 in this paper. The Honghu Lake National Nature Reserve and its surrounding 20 km area were taken as the research scope. The landscape index,artificial landscape disturbance index,and space neighbor effect evaluation model were used for the quantitative analysis. The results showed that,from 1995 to 2015,the proportion of the artificial landscape area in Honghu Lake Nature Reserve decreased from 9. 26% to 8. 95%,and the natural landscape area showed an increasing trend,indicating that the reserve was well protected. However,the disturbance index of the artificial landscape increased from4. 02% to 4. 93%,indicating that the impact of human development and construction activities on the reserve was deepening. In the peripheral areas of the nature reserve,the artificial landscape was the main area,with the area proportion increasing from 82. 75% to82. 97%,but the natural landscape area was decreasing continuously. The disturbance index of the artificial landscape increased from 26. 13% to 28. 87%,which was much higher than that in the nature reserve. There was a space neighborhood effect in the Honghu Lake Nature Reserve,and the main affected area was 4 km from the boundary of the nature reserve. It was necessary to pay attention to the landscape dynamics of the peripheral areas of the nature reserve,and formulate scientific control measures to reduce unnecessary development and construction and human interference while strengthening the management and control of human activities within the nature reserve.
