摘要:
针对历史文化资源保护的迫切需求利用高精度的地形数据和生态环境调查资料在GIS技术的支持下进行了历史文化遗址环境生态敏感性评价。以吐鲁番市区的历史文化遗址环境生态敏感性问题为研究对象选取高程等9个敏感性因子,利用层次分析法(AHP)确定敏感性因子权重结合GIS空间分析技术得到吐鲁番市区历史文化遗址环境生态敏感性结果。结果表明:吐鲁番市区历史文化遗址的生态敏感性总体较高,区域差异比较明显。国家级遗址和自治区级遗址都处在高度敏感状态,县市级遗址处在中度敏感状态,急需加强保护。最后提出分类保护措施为今后生态防范措施的针对性提供科学依据。
Abstract:
With regard to the urgent demands for protection of historic and cultural resources, on the basis of topographical data with high precision and eco-environmental survey information, by use of GIS, the ecological sensitivity of the environment of historical and cultural sites was evaluated. Ecological sensitivity of Turpan city was taken as the study target and 9 sensitive factors such as landscape density, elevation factor, landscape level, slope degree, etc. were selected. Analytic hierarchy process (AHP) was used to identify the weights of sensitive factors and GIS spatial analysis technique was adopted to obtain the spatial distribution of comprehensive ecological sensitivity of the environment of historical and cultural sites in Turpan City. The results showed that ecological sensitivity of the historical and cultural sites in Turpan City was comparatively higher in general, but with obvious regional differences. The sites in national and autonomous levels were in a highly-sensitive state and those in municipal and county levels were in a moderately-sensitive state, with urgent needs for protection strengthening. Finally, classification protection measures were proposed, providing a scientific basis for ecological protection in the future.
