Abstract:

The mechanism of coordination and adjustment of eco-ecological system are explored by using coupling degree model and coordination degree model and the neural network model as theoretical basis and factor contribution degree of eco-ecological system in Dongting Lake Area as guidance. The outcomes indicated that: 1) The variation trend of the coupling degree was smooth during 2003-2012, their coupling degrees was basically at resisting stage from 2003 to 2011, and coupling degrees during 2012 were becoming gearing stage. The annual variations order parameter were stable, and trend of development was a dynamic process from disordering to ordering but the result was clearly not ideal. 2) The coordination degrees of economy and ecological environment are lower from 2003 to 2012 in Dongting Lake Area, and transformed into moderate coordination in 2013. The coordination degree of economy and ecological environment in Dongting lake area remains to be further improved. 3) The coupling degree and coordination degrees inconsistent from 2003 to 2005. The variation trend of coupling degrees and coordination degrees are similar from 2006 to 2012. 4) The contribution degree of the evaluation factor of the ecological economic system was put further, which is reflected the impact effects of evaluation of a coupling or coordinate degree. The contribution degree of evaluation factor of ecological system was greater than economic system, which showed ecological system has a more important role than ecological system. 5) There was a positive correlation between the contribution degree and regulation degree. There was greater driving force of the coupling or coordinate when the factor contribution rate was greater.
