An Improved Index System of Regional Water Ecological Carrying Capacity Evaluation: A Case Study of Tieling City, China

Abstract:

This paper presents an improved Water Ecological Carrying Capacity (WECC) evaluation index system based on Pressure-Support Force-State (PSS) Index Framework. This index system can reflect the internal relationships of WECC, highlight the direct WECC impact factors, and to some extent avoid the past problems of selecting similar indicators and poor correlation indicators with WECC using former index systems. The WECC evaluation of Tieling City is processed under PSS index system. The evaluation results show that the average value of WECC is 0.59 from 2005 to 2010. It is concluded that this city is under a weak carrying level and generally in accordance with the real situation.
