摘要
为了维护人类社会与自然环境的平衡,更有效对区域生态环境进行规划和管理,以太湖县为研究对象进行生态敏感性分析,选取5个生态评价因子,采用GIS空间分析方法与层次分析法,综合评价太湖县生态敏感性。结果表明:1)在所选的评价因子中,水域缓冲区对太湖县的生态敏感性影响程度最大,坡度对其影响程度最低,二者的权重分别为0.4和0.07。生态敏感性影响从小到大排序依次为坡度、高程、土地利用、植被覆盖度、水域缓冲区。2)太湖县的整体生态敏感性较高,其中高敏感区和极高敏感区占比分别为29.23%和4.45%,中敏感区占比为29.93%,低敏感区和极低敏感区占比分别为26.19%和10.19%。3)太湖县的生态敏感性在空间上分布差异明显,表现为西北部地区生态敏感性较高,东南部地区较低。
In order to maintain the balance between human society and natural environment and plan and manage regional ecological environment more effectively,the ecological sensitivity analysis of Taihu County was carried out.Five ecological evaluation factors were selected and the ecological sensitivity of Taihu County was comprehensively evaluated by GIS spatial analysis and analytic hierarchy process.The results showed as follows:1)Among the selected evaluation factors,the impact of water buffer zone on the ecological sensitivity of Taihu County was the largest,and the impact of slope was the lowest,with the weights of 0.4 and 0.07,respectively.The effects of ecological sensitivity in descending order were slope,elevation,land use,vegetation coverage and water buffer.2)The overall ecological sensitivity of Taihu County is relatively high.The proportion of highly sensitive and extremely sensitive areas is 29.23% and 4.45%,the proportion of medium sensitive areas is 29.93%,and the proportion of low sensitive areas and extremely low sensitive areas is 26.19% and 10.19%,respectively.3)The spatial distribution of ecological sensitivity in Taihu County is significantly different,showing that the ecological sensitivity is higher in the northwest region and lower in the southeast region.
