| 摘 要： | 随长江干线航道基础设施体系的逐步完善，航道整治建筑物养护问题受到广泛关注。以长江干线航道养护数据为基础，通过泰尔指数、莫兰指数、标准距离等计算分析，研究航道整治建筑物技术状况时空特征。结果表明：航道整治建筑物数量及技术状况总体上逐年提升，2019年是泰尔指数转折发生年份；丁坝和护滩带等整治建筑物的养护需要重点关注；长江干线航道整治建筑物技术状况分布呈现显著的集聚效应，上游航道整治建筑物技术状况分布相较中、下游更集中。

| Abstract: | With the gradual improvement of the infrastructure system in the trunk stream of the Yangtze River channel,the problem of the maintenance of waterway regulation buildings is becoming more and more prominent.Based on the fundamental maintenance data of the Yangtze River channel,we calculate and analyze Thiel index,Moran index and standard distance to study the spatial-temporal characteristics of the technical status of channel regulation buildings.The results show that the number of channel regulation buildings and the technical condition grade is increasing by years,and 2019 is the turning point of the Thiel index.The maintenance of channel regulation buildings such as spur dike and beach protection belt need to be focused on.The distribution of the technical condition of channel regulation buildings in the trunk stream of the Yangtze River channel presents a significant clustering feature.In the upper reaches,the technical status of channel regulation buildings is more centralized compared to that of the middle and lower reaches. |
