针对5G限定域（DZ）网络质量评价中局部覆盖差异未量化、地理映射缺失、维度单一及权重静态化问题，提出融合Q-learning与双向小区影响度（BCI）的综合评价方法。方法首先采集多源数据并清洗，定义BCI量化小区与限定域的地理关联，分区域级（PRSRP）与小区级（故障/资源/容量）构建多维度评价体系，基于指数函数生成综合评价指数，最终通过Q-learning动态优化权重。预期实验表明，该方法评价准确率明显提高，场景适应性显著增强，可为5G网络优化、智慧城市通信保障提供技术支撑。

喀斯特槽谷区侵蚀坡面的土壤质量评价及障碍因子

Shuitu Baochi Xuebao
[目的] 为准确评价喀斯特槽谷区顺/逆层坡侵蚀坡面的土壤质量特征,筛选出适用于该地区的土壤质量评价方法,探析限制其土壤质量的障碍因子。[方法] 以重庆市青木关喀斯特槽谷区顺/逆层坡面的5种典型土地利用类型(林地、草地、裸地、玉米地、辣椒地)为研究对象,利用主成分分析法结合Norm值建立评价指标最小数据集(minimum data set,MDS),并通过非线性土壤质量评价方法和隶属度函数对喀斯特槽谷区顺/逆层坡面的土壤质量进行评价。[结果] (1)喀斯特槽谷区土壤质量评价指标最小数据集(MDS ...
