| 摘 要： | 以河北省南大港滨海湿地为研究对象,选取1989,1999,2009,2012年4期遥感影像及1969和1979年两幅分幅地形图为资料,获取南大港滨海湿地利用类型的面积数据。运用RS,GIS技术提取南大港湿地的动态变化信息,分析了影响南大港湿地演变的自然因素和人为因素。利用综合矩阵分析法和基于景观生态学的人为干扰强度模型评判法,定量评估了该湿地的退化程度,探讨了导致湿地退化的主导因素。结果显示:(1) 受自然和人为因素的影响,43 a间南大港天然湿地面积减少了37.22%,人工湿地面积增加了98.13%,特别是海水养殖场、水库坑塘和盐田等人工湿地的面积显著增加。(2) 1969年湿地基本处于自然状态,湿地退化影响因子综合指数较低,1979年以来综合指数显著增加。(3) 1969年人类对湿地的干扰程度甚微,1969-1979年人类对南大港滨海湿地的干扰强度为强干扰;1979-2012年人类对湿地的干扰程度尽管增幅不明显,但湿地仍在不断退化。

| Abstract: | Nandagang wetland in Hebei Province was took as the research area. In order to obtain the area data of Nandagang coastal wetland, four remote-sensing images of 1989, 1999, 2009, 2012 and two classified topographic maps of 1969 and 1979 as auxiliary information. Based on the dynamic change information of Nandagang wetland which extracted by using the RS and GIS technical, the natural factors and human factors influencing the evolution of Nandagang wetland were analyzed. By using the synthesis matrix analytic method and the intensity of human disturbance model, wetland degradation degree was evaluated quantitatively, and the main factors causing the degradation of wetlands were discussed. The result shows that:(1) Affected by natural and human factors, the natural wetland of Nandagang decreased by 37.22%, the artificial wetland increased by 98.13% in 43 years. Among all the artificial wetland, the marine park, reservoirs and ponds and the saltern have growth most obviously.(2) The wetland is almost in the natural state in 1969 and the comprehensive index factor of degradation is low, while the comprehensive index factor increased significantly since 1979.(3) The intensity of human disturbance is faint in 1969, the intensity of human interference on Nandagang costal wetland is strong in 1969-1979. The wetland disturbance degree was not obvious in 1979-2012, and wetland continues to degenerate. |
