Active Layout Algorithm for Monitoring Sample Points of Soil Salinity on Both Sides of Snow Melting and Deicing Section of Expressway
For uneven distribution of soil salinity monitoring points and low spatial coverage of each monitoring point,an active layout algorithm for soil salinity monitoring sample points on both sides of the snowmelt and deicing section of the expressway was proposed.According to the principle of distribution and division of sampling unit,the number of monitoring sample points was calculated.Based on this,a monitoring sample point layout model was established by using the maximum soil salinity value and the maximum target proximity as the main objectives.The model was solved by the spatial simulated annealing algorithm to obtain the best monitoring sample point layout plan.Taking a highway in the northeast of Yunnan province as a research case,the proposed method was used to arrange soil salinity monitoring sample points on both sides of the highway.The results showed that the proposed method was more uniform for the distribution of monitoring sample points,and the deviation index was lower.
