地质灾害发育强度等级图不仅能直观揭示发育强度及分布规律,而且可以为地质灾害预警和防灾减灾服务。袭扰系数法综合考虑地质灾害的发育密度和规模,全面反映了地质灾害发育强度等级,但其成图时往往需要对等级跨度过大的相邻单元格进行人为调整而带有主观性和不确定性,借助Surfer软件强大的插值功能和绘制图件能力,采用内插法绘制R值等值线图进行发育强度区划可以避免人为调整的主观性和不确定性。最后以米易县为例绘制了滑坡发育强度等级图。
The map of the development intensity of geological disasters can not only reveal the development intensity and distribution law intuitively, but also can serve for the early warning of geological disasters and disaster prevention and reduction. The harassment coefficient method comprehensively considers the development density and scale of geological disasters, and fully reflects the level of development intensity of geological disasters. However, when mapping, it is often necessary to artificially adjust adjacent sub-levels with subjective and uncertain With the help of Surfer’s powerful interpolation function and ability of drawing graphs, it is possible to avoid the subjectivity and uncertainty of human adjustment by plotting the R value contour map by interpolation. Finally, taking Miyi County as an example, the landslide intensity map was drawn.
