中文摘要：

我们在场为 Zostera 系船池 L 识别合适的区域的一个官方补给底的产地适用性索引(HSI ) 模型。在 Xiaoheishan 岛的 subtidal 地区的恢复。在模型，的控制因素重要性有序，是 Secchi 深度，沉积作文，水温度，咸度，当前的速度，水深度和滋养的质量。特定的因素 piecewise 函数被用来把参数值转变成规范的优秀索引。每个因素的重量用专家知识和分析层次过程(AHP ) 被定义方法。所有用反的距离因此获得的数据被插入内推加权(IDW ) 创造的插值方法为全部区域印射。在这研究，在 Xiaoheishan 岛的 subtidal 地区的产地适用性的分析被进行四个季节。根据官方补给底的 HSI 模型的意见， Zostera 系船池 L 的最佳的产地。出现在春天，尽管产地全年仍然保持合适。总体上，为鳗草恢复的最佳地点位于东方区域，由西方、南部的区域列在后面。我们相信官方补给底的 HSI 模型能是一个有希望的工具为 Zostera 系船池 L 选择地点。恢复并且能也在产地评估的另外的类型适用。

英文摘要：

We present a GIS-based habitat suitability index （HSI） model to identify suitable areas for Zostera marina L. restoration in the subtidal zone of Xiaoheishan Island. The controlling factors in the model, in order of importance, are Secchi depth, sediment composition, water temperature, salinity, current velocity, water depth and nutrient quality. Specific factor piecewise functions have been used to transform parameter values into normalized quality indexes. The weight of each factor was defined using expert knowledge and the analytic hierarchy process （AHP） method. All of the data thus obtained were interpolated using the inverse distance weighted （IDW） interpolation method to create maps for the entire region. In this study, the analysis of habitat suitability in the subtidal zone of Xiaoheishan Island was conducted for four seasons. According to the GIS-based HSI model, the optimal habitat of Zostera marina L. appears in spring, although habitat remains suitable all year round. On the whole, the optimum site for eelgrass restoration is located in the eastern region, followed by the western and southern regions. We believe that the GIS-based HSI model could be a promising tool to select sites for Zostera marina L. restoration and could also be applicable in other types of habitat evaluation.
