滨海滩涂翅碱蓬生长生境适宜性分析——以兴城曹庄海域为例

翅碱蓬在污染物去除、生态修复方面有着巨大的潜能，是我国北方退化滩涂湿地修复的重要物种。在翅碱蓬景观生态修复工程前，对其生长生境适宜性进行分析，有助于提高种植成活率，达到预期生态修复效果。本文运用GIS空间分析方法和SPSS统计学方法对兴城曹庄海域潮滩沉积物质量因子和重金属污染因子进行空间差值及统计分析，并据此进行了生境适宜性等级划分，结果表明:研究区翅碱蓬中度适宜以上面积高达194.6 ha，其中，中适宜性170.9 ha，高适宜性23.7 ha。利用无人机、GPS方式等开展修复面积、植被生长状况的现场验证，结果表明，翅碱蓬的生长状况与本文翅碱蓬生长适宜性评价结果重合度较好，各区域植被群落结构较稳定，植被生长状况良好。

Habitat suitability analysis of sueda salsa in Xingcheng Caozhuang tidal flats

Suaeda salsa shows potential benefits for pollutant removal and ecological remediation, and it is an important species of gradation wetland in northern China. Before the landscape ecological restoration project of Suaeda salsa, the analysis of its growth habitat suitability will help to improve the survival rate of planting and achieve the expected ecological restoration effect. In this paper, GIS spatial analysis method and SPSS statistical method are used to analyze the spatial difference and statistical analysis of sediment quality factors and heavy metal pollution factors in the tidal flat of Caozhuang sea area, Xingcheng City, and the classification of habitat suitability is carried out based on this. The results showed that the area of moderate suitability was 194.6 ha, of which 170.9 ha was moderate suitability and 23.7 ha was high suitability. The results showed that the repair area and the growth status of Sueda Salsa had good coincidence degree with the habitat suitability analysis, and the vegetation community structure of each region was stable, the vegetation is growing well.
