运用3S技术与景观指数软件,根据景观生态学原理对厦门红树林的景观演变过程进行分析。结果表明:从1960年以来红树林大面积减少,直到2000年开始进行人工种植恢复,红树林面积有所增加,但远不及原有水平,红树林在选定的5个时相中均有明显的变化。红树林的景观格局指数中景观相似性指数、平均斑块面积、形状指标变化趋势均表现为先减少后增加,单位周长的斑块数、边界密度变化趋势均表现为先增加后减少。最后,从驱动力的自然、人为因素角度对厦门红树林的景观变化进行了分析。
Using 3S technology and landscape index software, the landscape evolution of mangrove in Xiamen was analyzed according to landscape ecology. The results showed that the area of mangroves decreased greatly from 1960 to 2000, and the area of mangroves increased, but it was much lower than the original level. The mangrove forests were significantly different in the five selected phases The change. The trend of landscape similarity index, average patch area and shape index of mangrove landscape landscape pattern firstly decreased and then increased, the number of patch per unit circumference and the trend of boundary density all increased first and then decreased. Finally, from the perspective of natural and man-made driving forces, the landscape changes of mangrove in Xiamen are analyzed.
