Set Pair Analysis Method for Water Quality Evaluation Based on Nonlinear Power Function

Abstract

In this paper, synthetic evaluation method with nonlinear power function for membership function and systematic procedure are presented with set pair analysis theory. The case study shows the presented method works well in one building site of Bohai Bay and has advantages of concision, easy-operation and high precision, so the evaluation results are credible.

Trend Analysis and Quality Assessment of Sediment in the Marine District with High Strength Exploitation

“…Assessment model. In this paper, a nonlinear set pair coupling assessment model [4] is used for evaluating the environmental quality of sediment. Assessment result.…”

“…Assessment result. Following the detailed assessment procedure [4], indexes and levels of indexes shown in table 1, the environmental quality of sediment in Caofeidian marine district is slight (I). Although the quality is good, the high value exists in petroleum of 2007, that is the year of high strength exploitation.…”

Predictive Environment Carrying Capacity Assessment of Marine Reclamation by Prediction of Multiple Numerical Model

“…So many assessment methods have been proposed and applied to many fields including ocean water quality and carrying capacity [1][2][3] , but several defects exist in these methods [3] .…”
