With modern economic and social development, the technical and economic requirements of highway maintenance and construction projects have become increasingly complicated. Meticulous and in-depth investigation and demonstration guided by scientific theories and methods are of considerable importance to highway maintenance scheme decision. As basis for the selection of highway asphalt pavement recycling maintenance scheme, the factors influencing the decision are analytically demonstrated and an evaluation system is proposed, including three major decision indexes: applicability of recycling mode, recycled pavement quality recovery index, and economic benefit. According to the principles of data statistics and analysis, this study proposes a calculation method for the recycled pavement quality recovery index, analyzes the economic benefits of decision schemes using economic models such as recycling ratio and cost, and puts forward an optimal evaluation method of engineering cost and its fuzzy score intervals. Index weights are calculated through the analytic hierarchy process, and the comprehensive decision evaluation system and comprehensive evaluation method are established. Subsequently, the decision-making method is analyzed on the basis of the decision system by combining the related data. Results show maximum weight of the pavement quality recovery index and minor differences among four recycling schemes in the quality recovery index and applicability. The decision-making results are simplified with clear hierarchical feature because of the fuzzy score intervals of each index. Findings can provide a reference for the asphalt pavement recycling scheme decision.

Constructing livable eco-civilized cities has become one of the important tasks of the reasonable planning of urban development. The construction of an ecological city aims to achieve the harmonious coexistence of society, resource, and environment. However, the current evaluation method system of an ecological building encounters problems from a defective evaluation index. Hence, a relatively perfect evaluation index system is built. First, the analytic network process (ANP) is combined with the existing standards online. Then, a rapid calculation of the index weight is performed using Super Decisions software. Based on the needs of complicated problems, the classical TOPSIS model algorithm is improved by introducing the weight coefficient; this improved TOPSIS algorithm is then taken as the core to build a whole set of comprehensive evaluation method system for ecological buildings. The ecological urban agglomeration in Qinling Mountains of Xi’an is used in this study as the example to perform verification in practice. Contrastive analysis is performed on the evaluation results of the new and old buildings using this method system; the results indicate that the ecological effect of the buildings in the new area is much better than that of buildings in the old area. These results are mostly consistent with the evaluation results given by the expert group. Thus, the comprehensive evaluation system proposed in this article is reliable, and effective, as well as practical to some extent. This method can be used in a wider range of building evaluation and further improved in future studies.

The existing evaluation system of cultivated land quality mainly considers the natural quality and utilisation conditions, but without sufficient emphasis on ecological environment, which can’t meet the requirements of the trinity pattern protection policy. This study, using GIS spatial analysis and multifactor comprehensive evaluation method, constructed a comprehensive evaluation index system, and applied it in Shengzhou. The results show that: (1) under the comprehensive evaluation system, the quality of cultivated land was classified into five levels and revealed normal distribution with the third level cultivated land area as the peak, successive reduction to the two poles, and the overall quality was good relatively; (2) A close relationship was observed between the quality grade of cultivated land and the landform, the valley plain with highest cultivated land quality was the main grain-producing areas. However, the cultivated land in mountainous areas was poor relatively, and vulnerable to geological disasters; (3) The quality grade of cultivated land was related to economical activities directly. The high-quality cultivated land resources made these towns the main grain-producing areas with many agricultural industries distribution. This study provided a new assessment approach that can support cultivated land grading, quality improvement, and sustainable usage, as well as providing a reference for related research and application.

Abstract The current bid evaluation method can no longer meet the needs of green construction of railway construction projects, so a bid evaluation method based on an improved PCA-gray variable weight clustering model is proposed. A bid evaluation index system for railway green construction projects with a hierarchical structure was constructed from three aspects: basic construction ability, business ability and green construction ability, and the index evaluation criteria were given. Considering the high dimensional complexity of the bid evaluation system, the improved PCA method was used to reduce the dimension of the bid evaluation system, and on this basis, an improved linear weighted comprehensive evaluation function was constructed to preliminarily evaluate the construction ability of bidders. Then, the grey variable weight clustering model is used to construct the definite weighted function to further analyze the green construction ability of the bidders and select the optimal bidder. Finally, the method was applied to the bid evaluation of railway engineering projects from Lanzhouxi to Zhongchuan Airport, and the conclusion is consistent with the actual bidders, which proves the applicability and effectiveness of the model.

The weakness of the existing system of urbanization comprehensive evaluation is: evaluation Indexes were not comprehensive, and the evaluation system can’t reflect the real situation; analysis method was complex, and difficult to operate. We established evaluation index system from the economic development, social development, living, environment, infrastructure, spatial density, and urban-rural gap. We used entropy and comprehensive evaluation method to process and analyze the indicators. The results show that the quality of urbanization development is obviously different in Shaanxi Province, the effect of secondary cities is not obvious to promote the development, and the internal gap is still large in provincial cities and sub-index level.
