This paper analyzed the impact of the mountain highway on road domain ecosystems, and defined the concept and content of the road domain ecosystem ecological integration and its relationship with ecosystem health. Based on PSR framework, the ecological integrated measurement model was built. By constructing various subsystems indicators, the road domain ecosystem ecological integration was quantified by using the comprehensive evaluation method. On this basis, this paper divided the ecological integration into four grades: poor, moderate, good and excellent. It provided a theoretical basis for the ecological protection and restoration of the mountain highway construction.

This paper analyzed the concept and content of the road domain ecosystem ecological integration and its relationship with ecosystem health. Based on PSR framework, the ecological integrated measurement model was built, which divided the ecological integration into three subsystems, pressure, state and response. By constructing various subsystems indicators, the road domain ecosystem ecological integration was quantified by using the comprehensive evaluation method. On this basis, the ecological integration index was calculated along the highway at different distances of Yichang to Badong highway. The result shows that the road domain ecosystem ecological integration is relative to the distance on both sides of the highway. In the range of 0-5m, the ecological integration index is only 0.0408, which is gradually rising with distance increasing. To the range of 100-200m, the ecological integration index reaches 0.9343, which is close to the normal ecosystems level. This result is mainly related to the road construction disturbance. When it is closer to the road, the interference intensity is greater and the impact on the ecosystem is more obvious, which leads to the worse ecological integration. Conversely, the ecological integration is better.

Currently, the evaluation methods of importance measures such as structure importance measure, criticality reliability importance and B-reliability importance, have some shortcomings that the evaluation results are not comprehensive enough and the scope of usage. In order to accurately evaluate the importance measures of equipment, and to reflect the impact of the equipment on the communication network, a comprehensive evaluation method of importance measure is put forward. According to the influence of inherent structure of system and service reliability, the importance measure of equipment is calculated. By the coefficient modification, it can accurately evaluate comprehensive evaluation of electric power communication equipment based on reliability importance measures. Example result verifies the feasibility and validity of the comprehensive evaluation method.

The Impact

The premise that analyzing and studying the factors that affect urban pavement ecological physical environment (UPEPE), UPEPE impact factors are the thermal environment, sound environment, light environment, eco-energy saving design. This paper establishes the evaluation method for UPEPE which is based on fuzzy math. We evaluate the quality of UPEPE comprehensively in this way. Heat, light, sound and other ecological and physical environment effects are very important for creating good quality physical environment in urban pavement. In this paper, according to the impact factors of the UPEPE and using the fuzzy mathematical theory on evaluating the UPEPE comprehensively can reflect the real situation more objectively and accurately. The construction of model is simple and practical. Comprehensive evaluation utilizes the combination of the general public survey and expert evaluation, which benefits to reflect the democratic spirit. It also provides the reference to improve the UPEPE.

Climate change has become one of the major threats to global security. On the impact of climate change on national vulnerability, the researchers firstly select relevant factors and data and analyze the principal components to determine the weight of climate change on vulnerability so as to analyze the impact of climate change on national vulnerability. Secondly, based on the influencing factors, we obtain the national vulnerability score through the fuzzy comprehensive evaluation method, delineate the impact scope according to the score, and predict climate change by means of regression analysis and time series analysis. Finally, according to the characteristics of cities and continents, the model is revised, a PSR model and a cluster analysis model are established, and the prediction accuracy is improved.

Abstract River ecosystem health assessments provide the foundation for river ecological protection and integrated management. To evaluate the aquatic ecosystem health of the Fan River basin, benthic macroinvertebrate indices (the Multimeric Macroinvertebrates Index Flanders (MMIF) and Family Biotic Index (FBI)), a habitat index (the river habitat quality Index (RHQI)) and a water quality index (the Improved Water Pollution Index (IWPI)) were selected. The entropy weighting method was used to calculate the RHQI and IWPI. A fuzzy comprehensive evaluation method was used to evaluate the aquatic ecosystem health. The evaluation results indicated that the aquatic ecosystem health of the Fan River basin was better in 2018 than in 2011, which respectively belonged to the ends of the 11th and 12th Five-Year Plans of the Major Science and Technology Programs for Water Pollution Control and Treatment in China. The proportions of sampling stations with good, moderate and poor grades in 2011 were 50.0%, 40.0% and 10.0%, respectively, and in 2018, the proportions of stations with excellent, good and moderate grades were 20.0%, 50.0% and 30.0%, respectively. A correlation analysis showed that the RHQI was significantly correlated with the MMIF, FBI and IWPI. The riparian land use pattern was an important factor that influenced changes in the aquatic ecosystem health grade. Of the water quality parameters, total phosphorous (TP) and potassium bichromate index (COD) were the main factors that affected the characteristics of benthic macroinvertebrates and the aquatic ecosystem health.

With the increase of traffic volume, the enlarging tunnel span and the decreasing of surrounding rock integrity, the level of surrounding rock will be lower. This article proposed the calculating method of relative integrity index based on the concept of relative integrity of surrounding rock and established the Fuzzy Comprehensive Evaluation Method for rock classification by analyzing the impact of tunnel span enlargement upon rock stability. It also specified the determination factors, discussed the selection of weight indexes and proposed methods of establishing the qualitative and quantitative subordinate degrees. Based on practices of the expressways of Fuzhou, Xiamen and Zhangzhou, this article made fuzzy comprehensive evaluation of rock classification and fully analyzed the results of the evaluation. Results showed that with the enlargement of tunnel span, levels of surrounding rock would lower accordingly, and that the worse surrounding rock was, the more it would lower.
