摘　　要：以黄河流域河南段的99个国家森林乡村为研究对象,基于4类指数量化景观格局,选取社会经济因素表征不同半径缓冲区内的人为干扰强度,排除地理气候的影响,分析景观格局的空间分布特征及其对人为干扰的响应。结果显示:①黄河流域河南段中游西部和北部森林乡村的景观破碎度高,连通性和聚集度低;斑块及其核心区面积小,边缘密度大、斑块形状复杂,且景观多样性高。②偏相关分析显示,以上分布特征与人为干扰强度呈正相关,而与生态系统服务价值呈负相关。③景观格局对人为干扰强度的响应存在尺度效应,景观形状及多样性指数随着缓冲区半径的增加,相关性增强;而景观面积指数则随着缓冲区半径的增加,相关性减弱。这表明人类活动可能对景观格局产生负面影响,进而产生严重的生态问题。未来,在森林乡村建设过程中,该区域应寻求基于景观规划的解决办法,以实现社会经济发展和生态保护相统一。A total of 99 national forest villages in the Henan Section of the Yellow River Basin(the section in Henan Province)were taken as the research objects,the landscape pattern was quantified based on four types of landscape metrics.Socioeconomic factors were selected to represent the human disturbance intensity in buffers of different radii.After excluding the influence of geographical and climatic factors,the spatial distribution characteristics of landscape pattern and its response to human disturbance were analyzed.The results showed:①The Western and northern middle reaches of the Yellow River Basin(Henan section)exhibited high fragmentation,low connectivity and aggregation,small patch area and patch core area,high edge density,complex patch shape,and high landscape diversity.②The partial correlation analysis showed that the above distribution characteristics were positively correlated with human disturbance intensity,but negatively correlated with ecosystem service value.③There was a scale effect on the response of landscape pattern to human disturbance intensity.The correlation of landscape shape and diversity metrics increased with the buffer radius,while the correlation of landscape area metrics decreased with the buffer radius.These results indicated that human activities may have negative impacts on landscape pattern,and then lead to serious ecological problems.In order to realize a balance between the social and economic development and the ecological protection,the forest village construction of this region should prioritize landscape planning solutions in the future.
