斯里兰卡——洪涝致灾因子危险性空间分布（2023-03-14）

该数据提供了斯里兰卡洪涝致灾因子危险性的分析结果，从洪涝致灾因子危险性结果的空间分布来看，斯里兰卡暴雨洪涝致灾因子危险区具有东西两岸向岛屿中间呈条带状递减的趋势。中高危险区主要集中于岛屿的东北部以及岛屿的西南角两个部分，且危险性依次向周边范围递减。低风险区主要集中于岛屿中心偏南的腹地。

This dataset provides the analysis results of flood disaster-causing factor hazards in Sri Lanka. In terms of the spatial distribution of these hazard results, the hazard zones of rainstorm and flood disaster-causing factors in Sri Lanka show a zonal decreasing trend from the eastern and western coasts towards the island’s interior. The medium-to-high hazard zones are mainly concentrated in two regions: the northeastern part and the southwestern corner of the island, with the hazard level decreasing sequentially towards the surrounding areas. The low-risk zones are primarily located in the southern hinterland of the island’s central region.
