Abstract:

The evolution of the rural production space system is the representation or result of the exchange of material, energy and information within and out of the rural production space system. The pros and cons of this result is the endogenous material basis and guarantee which can realize the sustainable development of the system. This study sets Chongqing as the research area with a research period from 2001 to 2015 and establishes the index system of rural production space system evolution from four aspects of support-type input entropy, pressure-type output entropy, oxidation-type metabolism entropy and deoxidization-type metabolism entropy based on information entropy. The study reveals the evolution law and sustainable development capacity of rural production space system, analyzes the relationship between entropy change and sustainable development capacity of rural production space system in the process of co-evolution, and designs the optimal path for rural production space system. The results shows that: (1) From 2001 to 2015, the entropy flow of rural production space system in Chongqing is from 0.017 to -0.049 and the entropy production is from 0.204 to 0.059, which shows a downward trend; and the coordination and vitality of rural production space system are enhanced. The total entropy change is from 0.221 to 0.010, showing the same trend; the degree of order in rural production space system keeps improving, and generally, it is developing towards a healthy level. (2) From 2001 to 2015, the score of sustainable development capacity of rural production space system in Chongqing is from 1.285 to 2.803, showing an upward trend. The sustainable development of the system is in a good state and is evolving towards the sustainable direction. (3) The score of sustainable development capacity is positively correlated with support-type input entropy and deoxidization-type metabolism entropy, negatively correlated with pressure-type output entropy and oxidation-type metabolism entropy, and negatively correlated with entropy flow, entropy production and total entropy change.

Key words: rural production space system, information entropy, evolution, sustainable development capacity, Chongqing
