在详细阐释模糊聚类中目标函数聚类原理和方法基础上,选取22个与鄱阳湖区构造稳定性有关的变量,并利用KLL变换对该22个变量进行处理后,选取前5个因子变量代替原22个变量.采用网格单元的划分将全区分成167个网格单元,应用目标函数聚类方法(ISODATA)将全区167个单元进分成四个类别,利用GIS技术将该四个类别展布在空间上,根据它们各自的空间分布规律结合该地区现有的遥感图像线性构造解译成果和已有的地质、地震、重力、航磁等资料对四个类别区的构造稳定性进行分析,最终得出该区稳定性程度总体上由低至高为第一类区、第二类区、第三类区、第四类区.
Based on the detailed explanation of the principle and method of objective function clustering in fuzzy clustering, 22 variables related to the structural stability of Poyang Lake area are selected and the 22 variables are processed by KLL transformation. The first five variables are selected instead of The original 22 variables.Using the division of grid units, the whole area is divided into 167 grid units, and the target area function clustering method (ISODATA) is used to divide 167 units of the whole area into four categories, and the four categories Based on their spatial distribution and the results of linear interpretation of the existing remote sensing images in the area and the existing geological, seismic, gravity, aeromagnetic and other data, the structural stability of the four types of areas is studied Finally, the author concludes that the stability of the district is generally from low to high as the first category, the second category, the third category and the fourth category.
