摘要
为揭示库塘型国家湿地公园景观类型时空演变特征在自然因子上的变化与驱动因素,以永安龙头国家湿地公园的景观类型变化为基础,运用连续多影像数据解译出的景观类型图与地形、地形起伏度、集水区域3大自然因子进行叠加分析。通过分布指数变化情况,结合Spearson相关性分析,筛选对景观格局变化影响最大的驱动因子。结果表明:景观类型以稳定型为主,持续变化型体现在草地、建设用地与裸土地的不断变化中,且3类景观类型的转入率与转出率在2012—2020年间均下降;2012—2020年间裸土地与建设用地面积增加,其中,裸土地的地形位逐渐向中地形位发展,地势增加至低地势,可能会对湿地生态系统健康造成一定的影响;在Spearson相关性分析中,引起景观类型不断变化的主要驱动力是降雨侵蚀力,其他驱动因子较弱但也不可轻视。
In order to reveal the change and drivers of the spatial and temporal evolution characteristics of the Kutang National Wetland Park's landscape types in terms of natural factors,based on landscape type changes in Yong'an Longtou national wetland park.From the perspective of landscape type changes,the landscape type interpreted by continuous multi image data was superimposed with three natural factors:terain,topographic relief and catchment area.Through the change of distribution index and spearson correlation analysis,the driving factors that had the greatest impact on the change of landscape pattern were selected.The results showed that the landscape types were mainly stable,and the continuous change type was reflected in the continuous changes of grassland,construction land and bare land,and the transfer-in rate and transfer-out rate of the three types of landscape types declined from 2012 to 2020.The area of bare land and construction land increased from 2012 to 2020.Among them,the terrain of bare land gradually developed towards the middle terrain,and the terrain increased to low terrain,which may have a certain impact on the health of the wetland ecosystem.In spearson correlation analysis,the main driving force that caused the continuous change of landscape types was rainfall erosivity,and other driving factors were weak,but they could not be ignored.
