Study on Ecological Security Evaluation Index System of the Yellow River Basin

As an important energy base and ecological barrier in China, the security of Yellow River Basin has a very strategic position pattern high-quality development, but it is threatened by human activities climate change. In order to evaluate degree clarify influencing factors security, this paper discusses advantages disadvantages existing assessment methods models. On basis, system dynamics model used describe process threats, identify key that threaten then sort out indicators. The composed pressure(P), state(S), hidden dangers(D), response(R) management (M) (PSDRM) indicators constructed, processes are improved provide theoretical guidance technical support for improving basin.
