不断出现的新出现的感染地点，阻碍了消除血吸虫病的目标的实现。研究了1949 - 2016年湖南省钉螺新生境的时空分布特征。我们使用了1949年至2016年湖南省全年蜗牛调查的数据。采用全球Moran’s I统计量、Anselin本地Moran’s I统计量（LISA）和回顾性时空排列模型确定了新出现的蜗牛侵染点的时空分布。1949年至2016年期间，除了1993年、2009年和2012年，几乎每年都有新发现的蜗牛出没地点。新兴立地数量在1949 ~ 1954年、1955 ~ 1976年、1977 ~ 1986年、1986 ~ 2003年和2004 ~ 2016年5个时期差异显著（H = 25.35, p < 0.05）。新兴立地的平均持续时间为：沼泽37.52 a，丘陵30.04 a，内堤24.63 a，全球Moran’s I值分别为0.52、0.49和0.44。高价值空间集群主要集中在丽水河沿岸和湘阴县境内。1976年后有4个沼泽群、2个丘陵群和3个内河堤群。丽水河下游和洞庭湖入海口是钉螺新生境的高发区，病程长。应加强对河堤内钉螺顽固滋生点的监测。在蜗牛出没的草原上禁止放牧应该成为沼泽地的重点。湘阴县牛的管理具有重要意义。
Constant emerging sites infested with Oncomelania hupensis (O. hupensis) impede the goal realization of eliminating schistosomiasis. The study assessed the spatial and temporal distributions of new Oncomelania snail habitats in Hunan Province from 1949 to 2016. We used the data from annual snail surveys throughout Hunan Province for the period from 1949 to 2016. Global Moran’s I, Anselin local Moran’s I statistics (LISA) and a retrospective space-time permutation model were applied to determine the spatial and temporal distributions of emerging snail-infested sites. There were newly discovered snail-infested sites almost every year in 1949–2016, except for the years of 1993, 2009 and 2012. The number of emerging sites varied significantly in the five time periods (1949–1954, 1955–1976, 1977–1986, 1986–2003 and 2004–2016) (H = 25.35, p < 0.05). The emerging sites lasted 37.52 years in marshlands, 30.04 years in hills and 24.63 at inner embankments on average, with the values of Global Moran’s I being 0.52, 0.49 and 0.44, respectively. High-value spatial clusters (HH) were mainly concentrated along the Lishui River and in Xiangyin County. There were four marshland clusters, two hill clusters and three inner embankment clusters after 1976. Lower reaches of the Lishui River and the Dongting Lake estuary were the high-risk regions for new Oncomelania snail habitats with long durations. Snail surveillance should be strengthened at stubborn snail-infested sites at the inner embankments. Grazing prohibition in snail-infested grasslands should be a focus in marshlands. The management of bovines in Xiangyin County is of great importance.
