【摘要】 应用地理信息系统技术,探讨了划分血吸虫病流行区与非流行区的较好气温指标,并用其研究预测气候变化对血吸虫病空间分布的潜在影响。研究表明,随着全球气候变暖以及中国南水北调工程的实施,若钉螺扩散,且适宜钉螺孳生的其他条件满足,则存在钉螺北移的风险。若干年后,全球气候变暖对钉螺的分布和血吸虫病的防治将带来挑战,对此应给予足够的重视。更多还原

【Abstract】 The better index of air temperature that can be used to distinguish the epidemic area from non-epidemic area of schistosomiasis using Geographic Information System (GIS), and the potential impacts of climate changes on the spatial distribution of schistosomiasis, were studied. The result shows that Oncomelania Hupensis has the possibility to move north if the other conditions that affect the survival of Oncomelania Hupensis meet, with the global climate warming and the carry-out of south-north water transfer project in China. Global climate warming will cause great challenges for the schistosomiasis control and the distribution of the Oncomelania Hupensis in the future.更多还原
