GIS技术支持下的招远市金矿区崩塌遥感调查

在总结前人研究成果的基础上,全面系统地分析了诱发招远市金矿区崩塌的自然和人为因数,然后运用遥感技术对金矿区遥感图像进行处理,提取诱发崩塌的条件因子,聘请有经验的专家对各项诱发因子进行诊断分析,以此作为判断条件,在G IS技术的支持下对诱发崩塌的条件因子进行空间分析,预测出招远金矿区发生崩塌的危害程度,为防治崩塌提供科学依据。预测结果表明,招远金矿区崩塌有进一步发展的可能,其中,高危险区有36820 m2,中易发区有50 610 m2,低易发区有67 200 m2,需要采取有效措施加以防治。

GIS/RS-based Investigation on Landslip in Zhaoyuan Gold Field

Based on past research,the paper analyzed systematically and comprehensively the natural and artificial factors leading to landslip geo-hazard in Zhaoyuan gold field,Shandong.Though processing remote sensing image of the gold field on the basis of RS technology,the paper distilled the conditional factors that can induce landslip,and retained experienced expert to diagnose these inducing factors.Then using these diagnoses as judgment condition,it gave a spatial analysis of those conditional factors by GIS technology,and predicted the criticality of landslip in Zhaoyuan gold field,offering a scientific basis for preventing landslip.The prediction indicates that there exists probability of further developing of landslip in Zhaoyuan gold field.The high hazardous area is 36 820 m~(2),the middle hazardous 50 610 m~(2),and the low hazardous 67 200 m~(2).Effective measures are needed to take in order to control this crucial question.
