摘  要：
高速公路在推动城镇化建设过程中,会对区域生态环境造成破坏,本文以武汉市主干道高速公路为研究对象,利用缓冲区分析、景观指数法、生态价值评测等方法,以土地利用变化(LUCC)为基础分析2002年到2017年高速公路周边景观格局的变化。结果表明:(1)武汉市高速公路周边主要以耕地、林地、建设用地、水域和其他用地为主,耕地向建设用地转换最为显著;(2)在空间上,1～10 km缓冲区内主要以耕地、林地和建设用地之间的转换为主,随着时间推移,耕地所占比重持续减少,反之,建设用地持续增加,其空间差异有继续增大趋势;(3)2002年和2017年中的各土地利用类型的景观指数变化差异明显,水域的斑块密度和分离度最低,建设用地的分维度指数最高,耕地的分离度指数最高,这与土地利用变化一致,2002年城镇化对景观格局影响范围为4 km,到2017年扩大到6 km,影响有扩大趋势;(4)借助Google Earth和ESV对武汉市进行景观格局验证,与高速公路距离越远,景观类别越丰富,ESV值越高,主城区附近ESV值较低。总体ESV值呈下降趋势,LUCC降低了缓冲内的生态系统功能,造成生态服务价值减少。

摘  要：
In the process of promoting urbanization, expressways have also caused damages to the regional ecological environment. The buffer area analysis, spatial analysis, statistical analysis, landscape index method and MSPA method were used to analyze the impact of land use change on the landscape pattern around expressways. The results showed that:(1) The main types of land use around Wuhan Expressway were cultivated land, forest land, construction land,water and other land, and the conversion of cultivated land to construction land was the most significant;(2) In terms of space, the conversion between cultivated land, forest land, and construction land was mainly in the 1 ～ 10 km buffer zone. The area proportion of cultivated land continued decreasing with time. Conversely, the construction land continued increasing, and its spatial differences continued to increase;(3) From 2002 to 2017, the changes in landscape index of land use types were significantly different. The patch density and separation degree of waters were the lowest, the sub-dimension index of construction land was the highest, and the separation index of cultivated land was the highest, which was consistent with land use change. The influence of urbanization on the landscape pattern was at 4 km, and it expanded to be at 6 km in 2017, and the impact tended to be expanded;(4) With the help of Google Earth and ESV model, the landscape pattern of Wuhan City was verified. The farther away from the expressway, the richer the landscape category was, the higher the ESV value was, and the lower the ESV value was near the main city. The overall ESV value was declining, and LUCC reduced the ecosystem function within the buffer,resulting in a reduction in the value of ecological services.
