Scientific and practical crane evaluation index system is expected to obtain by screening of indices in this paper. The initial comprehensive evaluation indices are selected by stratification. Then the quantitative indices are screened by entropy method and Pearson correlation coefficient method, and the qualitative indices are screened by Delphi method and Spearman correlation coefficient method. The little effect indices on the evaluation result are deleted and the redundant information between the indices are got rid of. The index system simplified is comprehensiveness and representative, which is convenient to compare and evaluate cranes.

Microbiological Analyses

This study aimed to investigate the effects of the combined use of cellulose-decomposing bacteria (CDB) and heterolactic lactic acid bacteria (LAB) on corn silage fermentation. Fresh maize was treated with heterolactic LAB or CDB combined with heterolactic LAB inoculants or without any treatment. Chemical and microbiological analyses were conducted at specific times after ensiling. A comprehensive value evaluation was conducted using the principal component analysis model. Although all treatments significantly affected the microorganism numbers during fermentation, the numbers of aerobic bacteria, LAB, yeast, and molds in the groups with combined CDB and LAB were significantly higher than those in the group with LAB only (P< 0.05). All treatments regulated the silage CO2production. Each treatment had different effects on the nutrient degradation rate. Based on a comprehensive evaluation, the CDB and heterolactic LAB combination had the best effect on the ensiling process in improving the quality and feed value of corn silage.

The Index System

With expansion of enrollment scale, many universities make a large-scale expansion of their campus in recent years, which has caused a series of ecological problems, such as excessive occupation of land, destruction of local ecological environment. It is necessary to provide ecological level assessment and guidance for this eco-campus construction. Based upon the present related research at home and abroad and according to the basic principles of ecology, we have given a clear definition of ecological campus after considering the functional requirements for university campus at first, and then build an ecological campus evaluation index system in which the landscape ecology and the ecological footprint theory have been combined and clear the scoring method of each index. The index system includes five aspects: campus environmental quality, pollutant emissions, resource allocation and utilization, humanity landscape and greening, environmental awareness and environmental education. Furthermore, the analytic hierarchy process (AHP) is applied to this system to obtain the relative combined weights of every index which has passed the combined verify of coherence. Then the multi-factor comprehensive evaluation method was adopted to calculate ecological level index of eco-campus. At the end of this paper the main campus of Jinan University has been taken as an example application analysis of the index system.

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.
