| 摘 要： | 以蠡湖为例,利用GIS技术建立综合评价蠡湖水生动物栖息地适宜性评估的数量化方法。结合蠡湖自身的环境、生态和水文条件,通过咨询水产学专家,选取12个与水生动物栖息地适宜性评估密切相关的因子,并将之分为4个子模型。应用层次分析法确定选择因子对于水生动物栖息地适宜性评估的贡献率,即权重,建立水生动物栖息地适宜性评估模型,利用ARC/INFO软件内嵌的栅格数据分析模块生成单因子评价图层,结合栅格计算、空间叠加和分级模块,得出蠡湖水生动物栖息地适宜性的等级分布图,即水生动物栖息地适宜性评估为较高等级的区域面积为0.560 7 km2,水生动物栖息地适宜性评估为高等级的区域为6.568 2 km2,水生动物栖息地适宜性评估为一般等级的区域面积为0.720 9 km2,水生动物栖息地适宜性评估为低等级的区域面积为0.160 2 km2。蠡湖水生动物栖息地适宜性评估等级图为蠡湖的科学规划和管理提供了参考依据。

| Abstract: | This article focuses on evaluation method for the suitability of aquatic animal's habitat and takes Lihu as an example.A comprehensive quantitative method was established to evaluate 12 factors that connecting with environment,ecology and hydrology based on Geographical Information System and the above factors were divided into 4 sub-models.Analytic hierarchy process was applied to calculate each indicator's weight and set up the model on evaluation of the suitability of aquatic animal's habitat of natural ... |
