Land Ecological Security

Land ecological security is related to the sustainable development in every country. The ecological safety status of Poyang Lake Eco-economic Zone was chosen as study area in this paper. Based on Emergy, an evaluation index system of land ecological security is constructed from the perspective of the natural, economic and social factors. The AHP method was used to determine the index weights and multi-factor comprehensive evaluation method was also adopted to quantitatively evaluate and analyze the ecological security status of land use in the Poyang Lake Eco-economic Zone. The results show a downward trend from 2006 to 2010, the state of land ecological security changed from being comparatively safe to being critical safe. The value of ecological security for the Poyang Lake Eco-economic Zone decreased from 0.7031 in 2006 to 0.6576 in 2010.

According to constraint elements more and more appearing in the comprehensive forms, and at present it only considers that single constraint element of city underground space development and utilization has been unable to reflect the actual situation. On the basis of the main characteristics of city underground space development and utilization, this paper aims to analyze various factors which may cause the consequence and the frequency of appearance, and to construct evaluation index system of city underground space development and utilization which is composed of 5 one-level indexes, 20 two-level indexes of evaluation index system of multiple constraint factors of city underground space development and utilization, and to use the analytic hierarchy process and fuzzy comprehensive evaluation method to analyze and evaluate the influence on city underground space development and utilization. Analysis of the example application shows that, it only considers single constraint element of city underground space development and utilization is not comprehensive, and not science, and it needs to consider the correlation between various constraint elements.

To utilize the objective information of index data and consider the important role of subjective judgment in the evaluation of distribution automation equipment testing results, a comprehensive evaluation method based on AHP (Analytic Hierarchy Process) and CRITIC (CRiteria Importance Through Intercriteria Correlation) method is proposed. Firstly, an evaluation index system of distribution automation equipment testing results considering seven big indicators and thirty-six small indicators is established. Secondly, AHP and CRITIC method are adopted to solve a practical evaluation problem of distribution automation equipment testing results. The subjective weights of each evaluation index are calculated by AHP, the objective weights of each evaluation index are calculated by the CRITIC method. Then, to achieve the sorting of distribution automation equipment testing results accurately, the comprehensive weights are obtained by combining the two weights. Finally, the analysis and comparison of case studies show that the proposed evaluation index system can accurately reflect the performance of distribution automation equipment and the comprehensive evaluation method of distribution automation equipment testing results which comprehensively considers the subjective comprehensive evaluation results.

Highway collapse hazard is the combined result of many factors. Based on the formation mechanism of the road collapse hazard and main the factors, they are selected from three aspects of risk assessments master factor: the regional geological structure, slope characteristics, and regional environmental characteristics, also ultimately select the spacing of the joints, slope lithology, slope structure, slope height, slope gradient, rainfall (rainfall in 24 hours to ≥ 25mm of days), the vegetation coverage degree and earthquake strong eight main control factors, above all these factors, they established a road collapse hazard evaluation index system. Based on the fuzzy comprehensive evaluation method, it establishes a road collapse hazard evaluation model. Analytic Hierarchy Process is used to determine the evaluation index system of layers in index weight values. Risk index is based on the evaluation criteria. Finally, an empirical study of two highway projects instances.
