| 摘 要： | 以盐城湿地主要分布的3个县市:射阳、大丰和东台作为研究区,通过1988年至2006年每隔6 a的4期TM遥感影像,开展盐城湿地类型的动态变化分析,根据遥感影像解译结果,利用基于BP神经元网络的湿地演化CA模型进行湿地类型的变化预测分析。结果表明:研究区从1988年到2006年,耕地、居民用地、养殖场、米草、碱蓬面积总体呈增长趋势,滩地、芦苇和盐田呈急剧减少的趋势。大面积的滩涂开发是造成变化最主要的原因。预测结果为:未来的20 a内居民用地和养殖场将一直保持增加的趋势,米草逐渐占据优势物种的演化趋势。 |

| Abstract: | This paper took three main wetland distributing counties in Yancheng: Dongtai,Dafeng and Sheyang as study areas.With the processing of four-period(every six years from 1988 to 2006) remote sensing(RS) images,a dynamic change analysis of the Yancheng wetland types was illuminated.According to the results of the RS images interpretation,the change prediction of the wetland types was analyzed by using cellular automata(CA) model based on BP.The results showed that from 1988 to 2006,the area of cropland,residen... |
