For making timely and correct decisions for emergent pollution emergency of the water environment, combined with fuzzy integrated evaluation method, the model for the evaluation of emergency is established. Qinghe river basin is estimated in 3-level fuzzy integrated evaluation from 6 aspects. The results show that the score of emergent pollution emergency of the water environment of Qinghe river assessment is 3.9273,which close to a good level. The capacity of emergency support and emergency response is superior, and the abilities of emergency prevention, emergency decision-making and emergency recovery are relatively general, which should be completed.Emergent pollution emergency of the water environment is affected by many factors, a multi-target integrated evaluation system should be established. At present, the emergent pollution emergency system of water environment in our country still needs to be improved, the construction of which started relatively late, and the evaluation of which is at the exploration stage. To find the existing problems and shortcomings in emergency system of emergent pollution in water environment, the emergency evaluation index system is established, which improve the water environmental pollution emergency system. However, most of the indicators building the index system are qualitative, which has certain fuzziness when being estimated. Meanwhile it exists certain fuzziness when expressing characterizing attributes of the degree of realization and level of most evaluation indicators, and it is difficult to use specific, accurate data for quantitative description, generally it is expressed by fuzzy degree concepts like ‘Excellent, good, medium, qualified, bad’ and so on. Therefore, the emergent pollution of water environment is estimated by fuzzy integrated evaluation method in this paper.

Ecological civilization is a transcendence of industrial civilization. The improvement of China’s ecological civilization system can not only provide developing countries with an empirical reference for ecological civilization construction, but also make a huge contribution to the progress of global ecological civilization. This paper focuses on improving the provincial ecological civilization evaluation system. First, the Provincial Ecological Civilization Construction Evaluation Index System is established according to the Green Development Index System issued by the Chinese government in 2016, and then the applicability of the Spatio-Temporal Factor Analysis (STFA) is verified as the evaluation method of the provincial ecological civilization construction level. Further, taking Jiangsu Province, China as an example, this paper evaluates the level of ecological civilization construction in each city of Jiangsu Province, and analyzes the main factors affecting ecological civilization based on the evaluation results. Finally, according to the relationship between the ecological civilization construction and economic quality of each city, the four-quadrant method is applied to divide Jiangsu Province into four types of regions to help each city position itself in ecological civilization construction. This paper mainly draws the following conclusions: (1) Due to its simple operation and accurate evaluation results, STFA is applicable in evaluating the provincial ecological civilization construction level. (2) Taking Jiangsu Province as an example, it is found that the level of ecological civilization construction in the southwestern region is higher than that of the northeast coastal region in Jiangsu. Three inequality indices are applied to measure the regional inequality of ecological civilization construction among 13 cities, which is relatively high in recent years. (3) By analyzing the results of STFA, it is found that economic quality and natural protection are not only the main factors affecting the ecological civilization construction in Jiangsu province, but also the main reasons for the regional heterogeneity of provincial ecological civilization. (4) For the four types of regions, suggestions are proposed according to the characteristics of each region to help improve the provincial ecological civilization construction level. This paper not only improves China’s ecological civilization construction system, but also provides information for the provincial ecological civilization construction in developing countries.

Abstract In order to improve the evaluation system for the water conservancy photography creation base, evaluation indicators regarding the aspects of photographic resources, photographic elements, and water resources were selected to construct an evaluation index system, and the evaluation criteria for each index were provided. The optimal comprehensive weight for each evaluation index was determined following the moment estimation theory. The quantitative evaluation of the water conservancy photography creation base was carried out combined with the scoring standards for each index. The evaluation index system constructed here was then discussed in the application. This indicated that the evaluation index system is suitable in determining the construction status of the evaluated cases, thus, verifying its rationality. The comprehensive weighting of the indicators based on the moment estimation theory made the evaluation method more scientific and the corresponding results more reliable. This enabled the entire evaluation system and method to provide the theoretical support for the scientific evaluation of the water conservancy photography creation base.

As an important component of urban construction, the development of the community is of great significance to the sustainable construction of the entire society. The previous studies mainly focused on quantitative research and were limited by the data collectability, affecting the scientificity of the index system. Therefore, based on the theory of sustainable development, through the review of previous literature, combined with relevant experts' opinions and community development goals and other factors, a qualitative evaluation index system for community sustainable development capacity was established. The ANP (analytic network process) method is mainly used to determine the weight of each indicator, and FCE (fuzzy comprehensive evaluation) is proposed to determine every indicator’s membership. Then the hybrid fuzzy evaluation is promoted to evaluate the selected community as the empirical study. In this paper, the indicator selection is not limited by objective factors, and the evaluation system is more accurate; the application of ANP method makes the results of weight more scientific; meanwhile, fuzzy comprehensive evaluation can be suitable for solving various nondeterministic problems. This study transforms qualitative research into quantitative research; it provides an effective evaluation method for local managers and decision makers to carry out community sustainable construction.
