摘　　要：针对雨量监测计传统选址方法未顾及城市域复杂环境的问题,该文探索了城市域雨量监测计的选址条件,提出了基于空间核密度分析的雨量监测计选址模型。以空间核密度分析方法实现雨量计选址较好地平衡了城市域选址的地理环境约束;以雨量计设备信号传输等属性信息辅助并结合GIS缓冲区分析实现了雨量计选址的优选;利用3次实测降雨数据结合交叉验证方法验证了雨量计选址的合理性。实验结果表明,所制定选址条件及选址方法在城市域中具有较好适用性,对水文设备(积水计等)的选址分析具有较好的借鉴意义。In view of traditional site selection methods do not take into account the impact of geographic surrounding on the rain gauge site selection, this paper aimed at finding the proper site selection rules and methods for rain gauge in urban area. Using spatial kernel density could take into account the geographic surrounding in site selectiong GIS buffer analysis was used to optimize the location with the aid of rain gauge signal transmission character. The reasonability was validated by cross-validate method with the three-time rainfall real data. Experiment results showed that the rules and the proposed method were ＇appropriate for the rain gauge site selection in urban area, which was significant for the site selection of urban hydology equipment such as water gauge.
