【摘要】 为了探讨生态修复景观格局变化及其研究方法,运用GIS与RS技术,在景观生态学理论指导下,采用景观格局指数定量分析2009年、2013年和2016年太平国家湿地公园的景观格局和空间异质变化,其结果表明:耕地在2009年和2013年为景观格局的基质,水域在2016年为景观格局的基质;斑块数量、优势度、破碎度三个指标变化明显。斑块数量逐渐减少,其中荒草地、住宅用地斑块数量下降明显。耕地、园林地、住宅用地和水域的斑块形状趋于复杂,荒草地的斑块形状趋于均匀,其他建设用地的斑块形状没有明显变化。耕地面积虽然逐渐减少但一直处于主导地位,园林地和水域的面积逐渐增加,其他用地优势度均减少。耕地、水域、园林地、荒草地和其他建设用地的景观破碎度均减小,斑块逐渐聚集,而住宅用地破碎度指数略有增加。更多还原

【Abstract】 In order to explore the landscape pattern change of ecological restoration and its research methods,using GIS and RS technology and guided by the theory of landscape ecology, the quantitative analysis was conducted with landscape pattern indexes to figure out the heterogeneity change of landscape pattern and space in Taiping national wetland park in 2009, 2013 and 2016, the result shows that: Cultivated land was the matrix of landscape pattern in 2009 and 2013, and the water area was the matrix of landscape pattern in 2016. Three landscape patterns, the plaque number and the advantage and fragmentation degree of landscape, changed significantly in the whole process of wetland park construction. The number of plaques decreased gradually, and the number of patches in grassland and residential land decreased significantly. The patch shape of cultivated land, garden land, residential land and water area tended to be more complex, and the patch shape of the grassy field tended to be uniform, and the shape of the patches in other construction sites did not change significantly. The cultivated land area gradually decreased but remained dominant, the area of garden land and water area gradually increased, and the advantage of other land decreased. The landscape fragmentation degree of cultivated land, water area, garden land, wasteland and other construction sites decreased, and the patch gradually gathered, while the index of residential land fragmentation increased slightly.更多还原
