把云南省内发生过7级以上地震的九个区域和九个7级以下的地震区,分别作为图象分类的Ⅰ、Ⅱ两类区域,并将这两类区域的地质、地貌、地球物理等方面资料加以整理,应用误差修改训练的图象识别技术,借助电子计算机求得Ⅰ、Ⅱ两类的判别函数,然后把这判别函数应用于根据地质方法初步予测的18个地震危险区。得到寻甸、巧家、建水、玉溪、中旬、剑川、洱源、弥渡、普洱、宁蒗、澜沧、勐海、瑞丽、腾冲为7级以上地震危险区。 为了增加可信度,我们进行了两方面的验证。首先将得到的判别函数用于邻区四川和贵州的若干地区加以验证,而后把原来已知分类的通海、永善—大关、龙陵三个大震地区改变成未知分类的区域,用其余十五个已知分类区域的原始资料,使用同样的方法进行识别。其结果比较稳定,而且通海和永善—大关地区识别为Ⅰ类,龙陵地区判别值为0,界于Ⅰ、Ⅱ两类之间。通过验证说明此方法有一定效果,目前可作为地震危险区予测王作的一种试验方法。
Nine regions and nine earthquake regions below Seventh grade that have occurred earthquakes of magnitude 7 or above in Yunnan Province are classified as Ⅰ and Ⅱ respectively, and the geology, topography, geophysics And other aspects of information to be corrected, the application of error correction training image recognition technology, with the help of computer to determine Ⅰ, Ⅱ two types of discriminant functions, and then apply this discriminant function based on the preliminary prediction of geological methods 18 seismic hazard zone. Get Xundian, Qiaojia, Jianshui, Yuxi, mid-Jianchuan, Eryuan, Midu, Pu’er, Ninglang, Lancang, Menghai, Ruili, Tengchong earthquake risk zone above grade 7. In order to increase the credibility, we conducted two aspects of verification. First of all, the discriminant function obtained is used to verify some areas in the neighboring areas of Sichuan and Guizhou, and then the original known classification of the Tonghai, Yongshan - mark, Longling three large earthquake areas into unknown areas, with the remaining The original data of fifteen known classification areas are identified using the same method. The result is stable, and the Tonghai and Yongshan-Da Guan areas are identified as Class Ⅰ, while the Longling area has a discriminant value of 0 and lies between Ⅰ and Ⅱ. The results show that this method has some effect and can be used as a test method to test Wangzuo in the earthquake danger zone at present.
