【摘要】 通过对河南省水库大坝白蚁危害调查结果进行分析，揭示了白蚁在河南省水库大坝上的总体分布规律，并分析了不同类型、不同地区水库大坝白蚁危害程度和分布情况。结果表明：目前河南省四大流域中，除海河流域外均发现有白蚁危害发生，蚁害发生率呈现自南向北逐渐降低的分布规律；从水库类型看，大中小型水库蚁害发生率相差不大，且无明显规律。结合分析结果，对河南省水库大坝白蚁预防与治理工作提出了建议。更多还原

【Abstract】 Based on the analysis of the survey results of termite damage to reservoir dams in Henan Province, the damage degree and distribution of termites in different types and regions were revealed. The results show that except Haihe River Basin, termite damage has been found in all the four river basins in Henan Province, and the occurrence rate of termite damage gradually decreases from south to north; from the perspective of reservoir types, the occurrence rate of ant damage in large, medium and small-sized reservoirs has little difference and without obvious rules. Combined with the analysis results, suggestions on termite prevention and control for reservoir dam in Henan Province are put forward.更多还原
