摘要
近年来,山洪灾害发生频繁,严重威胁着山区人民生命财产的安全。由于山洪灾害成灾原因复杂,研究山洪灾害的危险性空间分布情况,使处于危险区的人们及时得到预警信息,及时采取防灾减损措施。以多态系统理论为基础,建立山洪灾害危险性评价模型,完成漳县危险区划分。结果表明:在不考虑降雨因素的情况下,漳县各乡镇均处于低危险区。在考虑降雨因素后,各乡镇发生山洪灾害的危险程度从西北向东南递增,与山洪灾害成灾机制相一致。
In recent years, mountain flood disaster occurs frequently, which seriously threatens the safety of people's lives and property in mountainous areas. Due to the complexity of the cause of the flood disaster, the research on mountain torrent disaster risk space distribution makes people receive timely warning information and take disaster prevention and mitigation measures. Based on multimode system theory, this paper establishes suitable risk evaluation model and completes the classification of Zhang County danger zone. The results show that un- der the condition of without considering rainfall factors, the townships are in low danger zone. After considering the factors of rainfall. The re- suits are correlated with the rainfall factors, consistent with the formation mechanism of flood disasters.
