摘要
本文采用Moran's I法,以年降水量等级为参数对松辽流域地区进行水文地理区划,同时分析了2019—2023年松辽流域地区年平均降水量的时空变化规律以及空间相关性;以年平均降雨量为影响因子,检验水文要素的全局和局部空间自相关性,避免传统区划中主观选择因子的局限性,确保区划依据更具统计合理性和地理意义。
In this paper,Moran's I method is adopted to conduct hydrogeographical zoning of the Songliao River Basin area with the annual precipitation grade as the parameter.Meanwhile,the spatio-temporal variation law and spatial correlation of the annual average precipitation in the Songliao river basin area from 2019 to 2023 are analyzed.Taking the annual average rainfall as the influencing factor,the global and local spatial autocorrelation of hydrological elements is examined to avoid the limitations of subjective selection factors in traditional regionalization and ensure that the regionalization basis is more statistically reasonable and geographically significant.
