The west Jilin Province is a typical area in the ecotone between agriculture and animal husbandry,with a frangible *** respect to the three aspects of water resource,natural disasters and land degradation,10 indices were selected to establish a matter-element model for the assessment of eco-environmental frangibility in the west Jilin *** results indicate that during 1985–2000,Qian’an,Fuyu,and Changling had the least frangibility(level Ⅰ),followed by Da’an and Qianguo(level Ⅱ),and Taobei,Zhenlai,Taonan,and Tongyu had the highest frangibility(level Ⅲ).On the whole,the counties in Songyuan city were less frangible than those in Baicheng *** counties had different frangibilities to environmental factors,e.g.,Da’an and Tongyu were frangible in water resource conditions;Taobei,Zhenlai,Taonan,Tongyu and Qian’an suffered most from natural disasters;while Taobei,Taonan and Qianguo were threatened by severe land degradation.

When water environmental carrying capacity of public resource tourist attraction is studied, the two action subjects of tourists and local residents should be discussed, and comprehensive consideration must be given to the influence of these two on water environment. On the basis of water resource carrying capacity and water quality carrying capacity, water environmental carrying capacity index of public resource tourist attraction was constructed, the model for the water environmental carrying capacity of public resource tourist attraction was established on the basis of matter-element model and analytical hierarchy process. By applying this method, water environmental carrying capacity situation of a certain public resource tourist attraction can be gained, moreover, situations about several aspects of water environmental carrying capacity can be evaluated.

A novel extension diagnosis method was proposed for enhancing the diagnosis ability of the conventional dissolved gas analysis. Based on the extension theory a matter-element model was established for qualitatively and quantitatively describing the fault diagnosis problem of power transformers. The degree of relation based on the dependent functions was employed to determine the nature and the grade of the faults in a transformer system. And the proposed method was verified with the experimental data. The results show that accuracy rate of the diagnosis method exceeds 90% and two kinds of faults can be detected at the same time.

The slope stability is affected by multiple factors. Thecomprehensive evaluation of the slope stability is a complicateproblem. The principles of extension theory have been used in thispaper to establish the matter-element model for the evaluation ofslope stability. The quantitative evaluated results have been giventhrough the calculation of the matter-element dependent degree.

Evaluation of pavement performance is one of the most important issues in a pavement-management *** employing the concept of entropy,the matter-element model for evaluating pavement is established,and the weights of the evaluation indices are obtained from sur-veying *** calculating the degree of dependence of the matter-element model,the pavement performance evaluation can be obtained by this *** results show that the matter-element model based on entropy right has good performance for evaluating the pavement condition in permafrost region.
