确定分区的指标体系是沙漠公路区划的核心问题。在进行中国沙漠公路自然区划研究的过程中,选取地貌、气候和生态等自然条件作为反映沙漠地区公路工程的环境影响因素,根据公度理论建立各要素对公路工程综合影响的定量参数——沙漠综合状态指数。最终建立了以沙漠综合状态指数为主导指标,以沙丘高度、风沙强度、植被覆盖度和气温年较差为辅助指标的中国沙漠公路自然区划指标体系,该指标体系的建立为中国沙漠公路建设奠定了基础。
Determine the index system is the core of desert highway planning. In the course of studying the natural divisions of the Chinese desert highway, natural conditions like geomorphology, climate and ecology are selected as the environmental factors that reflect the highway engineering in the desert area. Based on the theory of public degree, the quantitative parameters of the comprehensive impact of the various elements on the highway engineering are established - desert Comprehensive status index. Finally, the index system of natural divisions of the Chinese desert highway, which is dominated by the index of desert status and the auxiliary index of sand dune height, wind-blown sand intensity, vegetation coverage and temperature, is established. The establishment of this indicator system lays the foundation for the construction of China’s desert highway The foundation.
