Abstract. According to the meaning of ecological civilization, we build an evaluation index system of ecological civilization competitiveness. We select 30 provinces or autonomous regions in China, collect the relevant data and through principal component analysis 9 independent components are picked up from 19 comprehensive evaluation indices which reflect the competitiveness of ecological civilization. Then we evaluate and rank the regions’ ecological civilization competitiveness. By comparing the results, we find out strengths and gaps of the regions as well as the related reasons.

Effect Evaluation

The effect evaluation of video surveillance system is important for the effect of expected protection on the system. A comprehensive effect evaluation index system of video surveillance system is established. The Principal Component Analysis (PCA) method is applied on the established index system to obtain a new evaluation index system. It is proved in instances that the effect evaluation method of video surveillance system with the application of the index system is capable of evaluating the video surveillance system effectively and quantitatively. The protective effect of the video surveillance system is evaluated objectively on the basis of the new index system with the PCA.

Based on the importance of having an evaluation index system, a new method that combines PCA with graph distance classification is presented to make up the deficiencies of principal component analysis in the process of index screening, and this method is applied in the construction of an evaluation index system for the environmental quality of decommissioning uranium tailing. The seepage indexes were classified into six classes using graph distance classification, which selects the representative elements, including pH, ∑α, 210Pb, 210Po, F−, and NO3−. All of the representative elements were analyzed by PCA while determining the seepage indexes, including pH, U, Ra, ∑α, NH4-N, and F−, and establishing an index system for environmental quality evaluation that consists of two primary indexes (seepage and radiation environment) and 12 secondary indexes. The results showed that the model had ensured that the sifted indexes had a significant effect on the evaluation result and avoided the deletion of some important indexes and that it had stronger applicability and maneuverability.

Ecological civilization, a word with distinctively Chinese characteristics, will be the key strategy to address a series of problems in China’s economic transformation in the future. This study elaborated the concept and connotation of an ecological civilization from both narrow and broad perspectives, and established an evaluation index system with 26 specific indicators. These indicators were based on concepts to evaluate the development level of ecological civilization in mainland China and its 31 provinces (excluding Hong Kong, Macao, and Taiwan), autonomous regions, and municipalities from 2004 to 2016. The results reveal that China has achieved a transition in the development level of ecological civilization from low to intermediate as a whole, however, even rapid economic growth at the expense of the ecological environment cannot enable China to get rid of the fact that its social and economic development is lagging behind developed countries and regions. China and its various provinces, autonomous regions, and municipalities should gradually reduce their own deficiencies in the process of ecological civilization construction, under the premise of maintaining their own advantages, so as to achieve sustainable development and accelerate the construction of an ecological civilization.

Principal component analysis is performed on the operation and management evaluation of smart distribution network because of its objectivity, synthesis and simplification to original data information. According to the demand on the evaluation that focuses on intellectualization and reliability of distribution network, an index system for intelligent and reliable evaluation is built. The performance indicators and the principal component analysis are used to analyze the intelligent and reliable level of distribution network operation and management. The feasibility of the evaluation index system is verified by the evaluation results of some distribution networks.

Abstract Water ecological civilization is an important component and basic guarantee of ecological civilization. With the comprehensive development of ecological civilization in China, the practice of water ecological civilization village construction has been carried out one after another. The establishment of an evaluation index system of rural water ecological civilization is an important step in the construction of rural water ecological civilization from the theoretical stage to the practical application stage. Based on China's rural water conditions, this study constructed an evaluation index system, including 21 evaluation indicators of seven subsystems: water security, water environment, water ecology, water management, water landscape, water culture, and regional characteristic indicators. The indicator weights are determined by the analytic hierarchy process, a set-pair analysis model is established, and typical rural were selected for instance verification. The results show that the evaluation index system of rural water ecological civilization is reasonable, and the comprehensive evaluation model is also feasible.

Sustainable Development Ability

Based on the resource-based cities, we could establish a comprehensive evaluation index system. Principal component analysis (PCA) model is perfect to such evaluation. It can eliminate the related influence between evaluation indexes and reduce the workload of evaluation. The paper applied the principal component analysis to Baotou city and other 5 western resource-based cities so as to make a comprehensive evaluation about sustainable development ability. The results show that the sustainable development ability of Baotou city from2003 to 2012 is a fluctuated improving trend. And it ranks fourth in the selected western resource-based cities. The issue about the way to improve the sustainable development ability of resource-based cities is discussed in this paper.

According to the principles for index design, based on the existing index systems of other related industries, this paper proposed the conceptual model of internal potential influence factors for integration of freshwater fishery industry chain. On such basis, this paper screened out the observed variables that explain each influence factor, i.e. bottom indexes, established the comprehensive evaluation index system for integration of freshwater fishery industry chain, and then constructed the structural equation model for integration of freshwater fishery industry chain, and fitted and optimized the model by confirmatory factor analysis. Principal component analysis was applied to comprehensively evaluate the integration performance of freshwater fishery industry chain.
