Construction of coordination evaluation system of Economy-Tourism-Ecological environment coupling based on entropy method——Taking three cities in the Dongting Lake Eco-economic Zone as an example

Abstract

Dongting Lake Ecological Economic Zone is an emerging development group, among which Yueyang, Changde, and Yiyang have similarities in climate, environment, history, culture, and basic industries. This paper used the entropy method to construct the evaluation system of the coupling coordination degree of the three indexes of economy, tourism, and ecological environment in Yueyang, Changde, and Yiyang, calculated Yueyang, Changde, and Yiyang’s coupling coordination degree, studied and analyzed the relationship of its three subsystems in 2009, 2012, 2015 and 2018 of Yueyang, Changde and Yiyang, and analyzed their coupling coordination level. The results show: (1) the three major system evaluation indexes were generally on the rise, except for the Yiyang tourism evaluation index, which declined from 2012 to 2015; (2) These three systems’ coupling degrees were maintained at a very high level, and the development correlation is strong; (3) Some of Yiyang's data fluctuated in some years. By 2018, all the cities had reached the verge of imbalance from the extreme imbalance in 2009; The imbalance had greatly improved.
