- Abstract:
- In order to explore applicability of the improved TOPSIS in the stability analysis of land eco-economic system, 20 indicators from the four aspects (econemy, land, environment and society) were selected to build the stability evaluation index system of land eco-economic system. The improved TOPSIS was used to evaluate the stability of the land eco-economic system of Liaocheng City from 2003 to 2014, and the comprehensive index method was employed in the verification. The results showed that:(1) the developing process of the stability of land eco-economic system in Liaocheng City was divided into two stages:slow decline stage (2003-2006), system closeness degree is 0.324 to 0.271; restoration and development stage (2006-2014), system closeness degree is 0.271 to 0.661; it could be seen that the stability of land eco-economic system in Liaocheng City was developing in a good direction from 2003 to 2014 as a whole, which was consistent with the result of the comprehensive assessment; (2) the main factors restricting the development of the stability of land eco-economic system in Liaocheng City were the proportion of total agricultural output value to the GDP, the road land index, the cultivated land area per capita, the amount of applied fertilizer per unit of cultivated land and the natural growth rate of population. Thus, it could be concluded that the improved TOPSIS could objectively reflect the status of the variation of the stability of land eco-economic system in Liaocheng City, which was suitable for the evaluation on the stability of the land eco-economic system.
