Abstract Nonpoint source (NPS) pollution has been studied for many years but it exhibits random, widespread, complex uncertainties which make it difficult to manage and control. We employ group decision-making utilizing the fuzzy comprehensive evaluation method (FCE) and the analytic hierarchy process method (AHP) and comparatively evaluate the optimal allocation of NPS pollution control measures. Here, we present the top-three evaluation results ranked as follows: combination of contour tillage and vegetative filter strips (CT & VFS), vegetative filter strips (VFS), and combination of contour tillage and fertilizer reduction and vegetative filter strips (CT & FR & VFS). The fourth, fifth and sixth results by FCE method are chemical fertilizer reduction (FR), returning farmland to forest or pasture (RF), and combination of contour tillage and fertilizer reduction (CT & FR), while the corresponding results by AHP method are returning farmland to forest or pasture (RF), combination of contour tillage and fertilizer reduction (CT & FR), and fertilizer reduction (FR). The seventh results for each of the two methods are contour tillage (CT), which has a positive but limited effect on nutrient loss reduction. Our results provide new underlying insights needed to guide the resonable allocation of NPS pollution control measures.

Comprehensive Evaluation Method

Vehicle air quality is attracted attention more and more with the increase of private vehicles popularization rate but the air quality evaluation is difficult to achieve standardization in the short term. The main pollutants affecting vehicle air quality were analyzed. Index factors were identified and the classification method of vehicle air quality evaluation were determined combining with China and international air quality standards. Fuzzy comprehensive evaluation method was established for vehicle air quality evaluation. According to the degree of different pollutants harm to human body, weight of each index factor was determined. The evaluation results would provide theoretical basis for the comparison of different vehicle air quality conditions and vehicle air pollution control.

Nonpoint Source Pollutants

The riparian zone is a transitional zone between aquatic and terrestrial ecosystems and is also the only passage for surface runoff to enter a river. The role of the riparian zone as a means for intercepting nonpoint source (NPS) pollution has been receiving growing attention and, in recent years, various ecological revetments have been developed to strengthen the interception of runoff pollutants. This research reviews the current development of ecological revetments in terms of NPS pollution control with a focus on the key functions and optimization methods of vegetation allocation and substrate configuration. Future research on improving the ecological revetments for enhanced NPS pollution control are also highlighted. This review is intended to provide a technical reference for the optimization and implementation of ecological revetment projects, and possible pathways for the effective control of NPS pollution.

Agricultural Nonpoint Source

Purpose – In the USA and Europe, agricultural nonpoint source (NPS) pollution continues to be among the chief impediments to achieving water quality standards. While the implementation of technology-based water pollution control tools has resulted in evident point source pollution abatement, NPSs continue to threaten surface water and groundwater. The purpose of this paper is to draw from environmental policy literature to identify regulatory tools and management approaches that specifically target agricultural NPS pollution and the factors that drive or impede their implementation and enforcement. This paper utilizes the policy tool framework to help characterize the widespread policy problem, distinguishing its unique set of hurdles from other environmental problems. Design/methodology/approach – Discussion of agricultural NPS pollution management approaches is based on a thorough review of relevant environmental policy and environmental economic literature as well as case studies from the USA and Europe. Analysis is based on the policy tool framework. Findings – This study finds that controlling numerous diffuse sources of agricultural pollution requires an integrated approach that utilizes river basin management and a mix of policy instruments. Additionally, findings suggest that transitioning from voluntary mechanisms to more effective instruments based on measurable water quality performance relies predominantly on three factors: first, more robust quality monitoring data and models; second, local participation; and third, political will. Originality/value – This research provides important information for regional and national policymakers in areas where there is increasing pollution and regulatory mandates. Identifying conditions of effective water quality policy is applicable and will be of direct use to agencies charged with pollution control.

The decision of bidding risk in International Engineering project faces many risk factors. It is of significance to identify precisely the assessment of the risk correctly. A concise and practical method of assessing the tender decision risk is presented in this paper based on the principle of AHP method and fuzzy comprehensive evaluation method. We take Inner Mongolia Power Company Limited H 2 × 600MW project for example to verify the practicality and effectiveness of the system. Finally, considering of thermal power construction project's bidding risk characteristics, then we offer some risk control measures, which provides a more objective and applicable method for the risk management in international projects.

Air quality in car is attracted attention more and more but the air quality evaluation is difficult to achieve standardization in short time. The fuzzy comprehensive evaluation method was introduced in this paper. The in-car air quality classification method was determined. Weight of each index factor was determined according to the degree of different pollutants harm to human. The evaluation results would provide theoretical basis for the comparison of different in-car air quality conditions and air pollution control. An example was given to illustrate the application of the fuzzy comprehensive evaluation method.
