摘要
杭州湾南岸湿地是环杭州湾地区重要的区域生态安全屏障。以杭州湾南岸湿地为研究区,利用2006年、2011年和2016年3期遥感影像,提取湿地空间分布信息;采用转移矩阵方法,分析湿地空间变化和各类型湿地的转移方向;利用景观指数,研究杭州湾南岸湿地景观格局的变化特征及驱动因素。研究结果表明,2006-2016年期间,研究区湿地总面积持续减少,淤泥质海滩被开发为海水养殖场,稻田转变为非湿地;各类型湿地在景观中均衡化分布,湿地景观趋于破碎化;总人口数量迅速增加、城市快速发展、工业发展和政策导向是导致研究区湿地萎缩的主要驱动因素。
The wetlands in south coast of Hangzhou Bay are an important regional ecological security barrier in Hangzhou Bay area. Taking the south coast of Hangzhou Bay as the research area, the spatial information of the wetlands was extracted by using remote sensing images on April 29, 2006, May 20, 2011 and May 1,2016. The spatial variation and transfer direction of various types of the wetlands were analyzed using the transfer matrix method. The characteristics and driving factors of the wetlands landscape patterns were studied by the landscape indexes. The results showed that during the period from 2006 to 2016, the total area of wetlands in the study area continued to decrease, the muddy beaches were developed as marine farms, the paddy fields were converted into non-wetlands, the types of wetlands were evenly distributed in the landscape,and the wetland landscape became fragmented. The rapid increase of the total population, rapid urban development, industrial development and policy orientation are the main driving factors of wetlands shrinkage in the study area.
