| 计算生境适宜指数可以实现生境质量量化。利用GIS空间分析中的反距离权重插值法对双台子河口潮滩湿地土壤质量因子和土壤污染因子进行空间插值,并依此进行生境适宜性等级划分。结果表明,双台子河口潮滩湿地研究区域内大部分区域均适合翅碱蓬和芦苇生长,由于土壤水分和盐分含量的限制,属于翅碱蓬和芦苇生长次适宜生境和边缘生境,仅有少量区域属于翅碱蓬生长核心生境,而在潮间带区域没有芦苇生长核心生境。 |

| Calculating habitat suitability index can achieve quantification for habitat quality. This paper investigated the spatial interpolation of factors relating to soil quality and soil pollution in the wetlands of Shuangtaizi estuary using inverse distance weighted(IDW)，a method of interpolation on geographic information system(GIS).The habitat suitability of Suaeda salsa and Phragmites australis were classified into four classes. The results showed that the most areas in the wetland of Shuangtaizi estuary studied were suitable for growth of S. salsa and P. australis. However, as the restriction of the water and salt contents in the wetlands，the most areas were inferior habitat and marginal habitat. Only a few areas were core habitat for growth of S. salsa and there was no core habitat for growth of P . australis in intertidal area. |
