本研究的目的是确定与钉螺分布相关的景观生态决定因素，绘制钉螺潜在高风险地图。在微尺度上对湖北钉螺栖息地进行了研究，并评估了两种环境控制策略的效果。对潜江市242个有螺点和726个无螺点进行了调查。采用景观格局分析与多元Logistic回归模型相结合的方法，研究了环境因子对钉螺栖息地的影响。钉螺栖息地的风险概率与斑块分形维数（FD）、水田比例和湿度指数呈正相关，与植被指数（NDVI）和海拔高度呈负相关。这些发现表明，FD可以识别不规则特征（例如，平原地区灌溉沟渠），中等的NDVI会增加微尺度风险概率。根据所观察到的决定因素，我们预测了一个地图，显示高风险地区的蜗牛栖息地和模拟的影响，管道硬化和水田轮作旱地。这两种方法均能有效控制钉螺。这些发现为当地血吸虫病防治站的卫生专业人员确定优先区域和有前途的环境控制策略提供了经验依据。
This study aims to identify the landscape ecological determinants related to Oncomelania hupensis distribution, map the potential high risk of O. hupensis habitats at the microscale, and assess the effects of two environmental control strategies. Sampling was performed on 242 snail sites and 726 non-snail sites throughout Qianjiang City, Hubei Province, China. An integrated approach of landscape pattern analysis coupled with multiple logistic regression modeling was applied to investigate the effects of environmental factors on snail habitats. The risk probability of snail habitats positively correlated with patch fractal dimension (FD), paddy farm land proportion, and wetness index but inversely correlated with categorized normalized difference vegetation index (NDVI) and elevation. These findings indicate that FD can identify irregular features (e.g., irrigation ditches) in plain regions and that a moderate NDVI increases the microscale risk probability. Basing on the observed determinants, we predicted a map showing high-risk areas of snail habitats and simulated the effects of conduit hardening and paddy farming land rotation to dry farming land. The two approaches were confirmed effective for snail control. These findings provide an empirical basis for health professionals in local schistosomiasis control stations to identify priority areas and promising environmental control strategies for snail control and prevention.
