摘要:为探究山东渤海滨海地区互花米草时空分布特征,本研究选用Iandsat遥感影像,基于支持向量机(SVM)算法对山东渤海滨海地区互花米草开展动态监测。结果表明:①2010年、2015年和2019年山东渤海滨海地区互花米草分布面积分别为20.33kmr'.22.34km'和48.77km';②互花米草主要分布于黄河三角洲地区、五号桩东部海岸、孤东油田东北角和小清河河口附近等,且在不同区域呈现不同的空间分布特征。
Abstract: In order to explore the spatiotemporal distrilution characlteristics of spartina altemiflora in the coastal area of ShandongBolai ea, tis studly selected lLandsat remole sensing images and conducted analysis based on support vector machine (SVM) algorithm.The resuls show that:① In 2010, 2015, andl 2019, the ditribution aras of Spartina altemiflora in the coastal areas of Shandong Bohai Seawere 20.3km', 22.34km', and 48.77km', respectively;②Spartina altermniflora is mainly dlistributed in Yellow River Delta, the eastern coastof pile 5， the northeast comner of Gudong Oilfield,and near the Xiaqing River estuary，and presents different spatial distributioncharacteristics in different regions.
