摘　　要：针对当前土壤盐度监测点布设存在监测点布设不均匀、各监测点位空间覆盖率较低的问题,提出高速公路融雪除冰路段两侧土壤盐度监测样点主动布设算法。根据布点和采样单元划分原则,计算监测样点数量,以此为依据,以土壤盐度值最大和目标贴近度最大为主要目标建立监测样点布设模型,采用空间模拟退火算法对模型求解,得到最佳监测样点布设方案。以滇东北地区某高速公路为研究案例,利用所提方法对公路两侧土壤盐度监测样点进行布设,结果表明,所提方法对于监测样点的布设较为均匀,偏离指数更低。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.
