Abstract
As a large agricultural nation, China attaches great importance to agricultural development, as sustainable, regional agricultural development affects the sustainable development of China. Taking Chengdu, Sichuan Province as an example, this paper selected indicators and data from the past 15 years from the Chengdu Statistical Yearbook and applied the dissipative structure theory to establish an evaluation system for sustainable, regional agricultural development based on five main factors including economy, society, environment, education, and population. The entropy weight method was used to empower each indicator, and the changes in Chengdu’s sustainable agricultural development in the past 15 years were calculated. It was found that Chengdu’s sustainable agricultural development has been annually increasing, among which, economic and education subsystems had the greatest support for sustainable agricultural development. From 2003 to 2017, the entropy change of the total agricultural sustainable development system in Chengdu was negative, and the total entropy of the system gradually decreased. The sustainable agricultural development system in Chengdu has been developing towards a more orderly dynamic equilibrium state.
Highlights
As agriculture is an economic activity, a livelihood, and a provider of environmental services, it contributes significantly to a country’s development [1]
One of the key research directions for sustainable, regional agricultural development has been the construction of viable evaluation systems, which have generally consisted of three aspects including the economy, society, and the environment as well as their associated dimensions [6,7,8]
Following the principles of scientific soundness, completeness, rationality, operability, effectiveness, and comparability, the regional agricultural sustainable development system measurement index system was constructed from the five dimensions of economy, society, environment, education and population (Framework of ESEEP)
Summary
As agriculture is an economic activity, a livelihood, and a provider of environmental services, it contributes significantly to a country’s development [1]. For agricultural development to be sustainable, there needs to be a balance between the economy, the environment, and the society [3]. Because agriculture is the foundation of China’s national economy, the sustainable development of regional agriculture, which involves the interaction of many factors such as nature, the economy, society, population, and the environment, is fundamental to sustainable, regional development [4]. China needs to develop a more sustainable agricultural system, which is a complex problem that involves many factors such as the agricultural economy, agricultural technology, agricultural environment, and rural development, each of which are interrelated and constrained in a dynamic information feedback system [5]. The measurement system of sustainable, regional agricultural development in Chengdu has not been systematically studied. The main research question of this study is to analyze and measure the sustainable, regional agricultural development in Chengdu, provide theoretical support to comprehensively measure the sustainable development levels of agriculture in Chengdu, and give suggestions for the future development of agriculture in Chengdu
