摘要/Abstract

摘要： 河口湿地景观格局受人类活动影响剧烈，因此，研究人类活动强度对河口湿地景观格局的影响，对加强河口湿地生态保护具有重要意义。本文利用遥感影像、夜间灯光数据和人口数据分析了2013—2023年小清河口湿地景观空间特征，在此基础上，基于人类活动强度模型，定量分析了湿地景观格局对人类活动强度的响应，揭示了小清河口湿地景观格局沿人类活动强度的梯度变化规律。结果表明：近10年小清河口湿地总面积和景观多样性呈现出先减后增的趋势，景观破碎化程度和聚集度则表现为先增后降，而景观连通性变化不明显；小清河口人类活动强度空间分异显著；中、较高强度带人工湿地面积占比最大，高强度带自然湿地面积占比最小。小清河口人类活动强度与湿地景观指数存在显著的相关性，人类活动强度与PD、SHEI、SHDI、CONTAG呈显著正相关，与COHESION、AI呈极显著负相关。说明人类活动强度空间分异决定了小清河口湿地景观格局的发展方向，研究结果可为小清河口湿地保护和人类活动管控提供决策支持。

Abstract: The landscape patterns of estuarine wetlands are strongly affected by human activities. Therefore, investigating the impacts of human activity intensity on the landscape pattern of estuarine wetlands is of great significance for improving wetland conservation. In this study, we analyzed the spatial patterns of the Xiaoqing River estuary wetland landscape during 2013 to 2023 by using remote sensing images, night light data, and population data. We quantitatively analyzed the response of the wetland landscape pattern to human activity intensity based on the human activity intensity model and the gradient variations of the landscape patterns of the Xiaoqing River estuary wetlands along with human activity intensity. The results showed that during the past ten years, the total area and landscape diversity of the Xiaoqing River estuary wetlands showed a trend of initial decline and subsequent increase. The degree of landscape fragmentation and aggregation showed an initial rise followed by a decrease, whereas there were no changes in landscape connectivity. The spatial variations of human activity intensity in the Xiaoqing River estuary were substantial. The proportion of constructed wetlands with moderate and relatively high intensity of human activity was the largest, while the proportion of natural wetlands with high intensity of human activity was the smallest. There was a strong association between human activity intensity and wetland landscape indices in the Xiaoqing River estuary. The intensity of human activity had a positive correlation with PD, SHEI, SHDI, and CONTAG, and a significantly negative correlation with COHESION and AI. In conclusion, the spatial differences in human activity intensity determined the development direction of the landscape pattern of the Xiaoqing River estuary wetlands. Our findings can aid in decision-making about the management of human activity and the preservation of wetlands in the Xiaoqing River estuary.
