Evaluation of the Green Sustainable Development Ability of Chengdu Agriculture Based on Entropy Method

Abstract

Agricultural green sustainable development is a necessary condition to ensure long-term economic and social development in China. Based on the data of agricultural economy and society, resources and environment, this paper uses the entropy method to evaluate the sustainable development of green agriculture in Chengdu from 2011 to 2016. The results show that the overall capability of agricultural green sustainable development in Chengdu shows an upward trend year by year, and the index of development has risen from 0.1866 in 2011 to 0.9353 in 2016. The trend of each subsystem varies from each other. The sustained development of the economic system has the fastest growth rate, with an annual growth rate of 61.81%, followed by the improvement of the environment, whereas there is a greater pressure on the sustainability of resources. Although the impact of resources on sustainable agricultural development is on an upward trend, the resource sustainability index for 2016 is 0.0437, which is still at a low level. In order to comprehensively enhance the level of agricultural green sustainable development in urban areas, the paper puts forward some countermeasures such as establishing a system of agricultural productivity distribution, establishing a standard system of green agriculture, and improving management and control of agricultural resources and environment.
