摘　　要：目的探讨气候水文因素对疟疾发病率的影响,为制定疟疾防治策略提供参考依据方法收集2001～2010年邳州市疟疾疫情资料和平均气温、最高气温、最低气温、年降水最、平均湿度、年日照、年蒸发量、年总云量、年低云量等气候水文资料,采用Pearscon相关分析探讨各种气候水文因素与疟疾发病率之间的相关性。结果 2001～2010年邳州市共报告疟疾病例201例,逐年发病率分别为0.524/10万、0.521/10万、1089/10万、1.898/10万、1.747/10万、2 091/10万、2.213/10万、0.957/10万、0.53/10万和0.872/10万。总云量与疟疾发病率呈显著正相关(P=0.038),平均湿度与年日照呈显著负相关(r=-0.731,P=0.016),年总云量与最低温度呈显著正相关(r=0.745,P=0.013)。结论气候水文因素影响疟疾发病。Objective To investigate the impact of climate and hydrological factors on malaria morbidity, so as to provide evidence for making out control strategies. Methods The data on the prevalence of malaria and the climate and hydrological factors including mean temperature, maximum temperature, minimum temperature, annual precipitation, mean humidity, annual sunshine, annual amount of evaporation, annual total cloud cover and annual low cloud amount in Pizhou City from 2001 to 2010 were collected, and the relationship be- tween the climate and hydrological factors and malaria morbidity was analyzed by means of Pearson Correlation Analysis. Results A total of 201 cases with malaria were detected in Pizhou City from 2001 to 2010, and the incidence rate was 0.524, 0.521, 1.089, 1.898, 1.747, 2.091, 2.213, 0.957, 0.53 and 0.872 per hundred thousand, respectively. There was significantly positive correlation between annual total cloud cover and malaria morbidity （P=-0.038）, while there was significantly negative correlation between mean humidity and annual sunshine （r=-0.731, P=0.016）, and the annual total cloud cover was positively correlated with the minimum tem- perature （r=0.745, P=-0.013）. Conclusion Climate and hydrological factors effect the malaria morbidity.
