Regional vulnerability evaluation and zoning is a very complex process, which involves a lot of factors. And the methods of evaluation and zoning are various. Regional economic development and frequent disasters are incompatible in some ways, and extension method is an effective tool to solve incompatible problems.

Regional vulnerability evaluation and zoning is a very complex process, which involves a lot of factors. And the methods of evaluation and zoning are various. Regional economic development and frequent disasters are incompatible in some ways, and extension method is an effective tool to solve incompatible problems. So this essay probes application of extension method to regional vulnerability evaluation and zoning. First, the theory of extension method and steps of application of extension method to regional vulnerability evaluation and zoning are introduced,which includes selection of indexes, defining definition field and classical field of indexes, assignments of weight among the indexes, the first evaluation, calculation of single index correlative degree and synthetical correlative degree, and zoning according to synthetical correlative degree. Factor analysis is used to calculate the weight of indexes: factor analysis of the indexes is carried in SPSS and get the commonality of each index, then deal with the commonality with the formula:ω= i 2 2where ω is the weight of each index,  i is the commonality of each index. Since the commonality means how much the index can stand for the factors, it is reasonable to assign the weight among indexes using this method. It is proved that economic vulnerability degree contributes the most to synthetical vulnerability degree, social vulnerability degree is the next, and ecological vulnerability degree means the least. Second, Sichuan Province is taken as an example to test its effect of the application,results show that the area with highest and higher synthetical vulnerability degree takes up 85.88%, from which we can get the conclusion that vulnerability degree of Sichuan Province is high as a whole; in addition, synthetical correlative degree and single index correlative degree show that synthetical vulnerability degree and key restrictive factors differentiate a lot among regions, which means different measures should be taken according to different key restrictive factors.Zoning results show that Chengdu, Panzhihua and Deyang belong to the most slight degree, Zigong belongs to slight degree, Mianyang, Neijiang, Guang'an and Meishan belong to middle degree, Luzhou, Suining, Leshan, Nanchong, Yibing, Dazhou, Bazhong and Ziyang belong to severe degree, Guangyuan, Ya'an, Aba, Ganzi and Liangshan belong to the most severe degree. Last, a conclusion is given that application of extension method to regional vulnerability evaluation is practical, but one disadvantage of this method should be pointed out that K j(v i) is the distance between v i and ( a 0i ,b 0i ) , which makes it more difficult to compare the regions belong to the same degree. But with the development of calculating method of correlative degree, extension method will supply vast vistas on researches of natural border identification and natural elements zoning.

首先介绍了可拓方法的基本原理及其在区域易损性评判中的应用步骤 ,然后以四川省为例检验了其实际应用效果 ,探讨了可拓方法在区域易损性评判中的应用。结果表明 :四川省承灾能力总体偏低 ,其中极高易损区和高易损区的面积比重达 85 .88% ;并且易损性区域差异大 ,基本上呈连续成片分布 ,各区域存在的主要问题和制约因素也不同。最后指出将可拓方法应用于区域易损性评判中的思路是正确的 ,方法是可行的 ,并认为可拓方法在自然系统界线识别和自然要素空间分异等方面的研究中具有广阔的应用前景。

Comprehensive grey entropy evaluation, a new safety evaluation method based on grey entropy theory, is put forward. Grey entropy is the measure of balanced degree of discrete sequence. Grey correlative degree is the measure of adjacent degree between reference sequence and relative sequence. In this evaluation model, the balanced adjacent degree is derived from grey correlative degree and balanced degree. It is further taken as the rule of evaluation. As a result, the subjectivity...

Comprehensive grey entropy evaluation, a new safety evaluation method based on grey entropy theory, is put forward. Grey entropy is the measure of balanced degree of discrete sequence. Grey correlative degree is the measure of adjacent degree between reference sequence and relative sequence. In this evaluation model, the balanced adjacent degree is derived from grey correlative degree and balanced degree. It is further taken as the rule of evaluation. As a result, the subjectivity in ascertaining weights of low level multiple factors is avoided making the evaluation model more rational and evaluation result more objective. This method is applied to the safety evaluation of transportation system in the 6th mine Pingdingshan Coal Group Corp. Ltd. The evaluation result indicates that this method is more objective than other evaluation methods; the conclusion complies well with the reality in comparison with other methods. At the same time, the priority of the safety management in transportation is pointed out.

基于灰熵理论,提出一种新的安全性评价方法即灰熵综合评价。灰熵是离散序列均衡程度的测度,灰色关联度是参考序列和比较序列之间接近程度的测度。该法将灰色关联度和均衡度合成为均衡接近度,并以此作为评价准则,从而避免了低层次多因素权重确定的主观性,使评价模型更加合理,评价结果更加客观。通过利用多层次灰熵综合评价模型,对平顶山煤业(集团)有限责任公司六矿运输系统的安全性进行综合评价,其结果表明,该方法较其他评价方法更加客观,结论更符合实际,同时指出了今后运输安全管理工作的重点。

In this paper,the basic principle and method of grey correlation analysis is briefly introduced.The correlative degrees of the temperature of oxidation of coal and every indictor gas are figured out.The primary and secondary relation of the indictor gases is established.It provides basis for the veracity of predicting spontaneous combustion.

简要介绍了灰色关联分析的基本理论和方法。利用灰色关联分析法计算出了各标志气体与煤氧化温度之间的关联度,并以此来确定各标志气体的主次关系,为自然发火预测预报的准确性提供了可靠依据。
