广东省农业生态经济的时空变异分析

目的]农业生态经济系统是结合农业生态发展和经济发展的复合体,通过研究广东省农业生态经济的时空变化,为广东省农业生态经济的可持续发展提供理论依据。方法]通过查阅文献构建评价指标体系,利用熵权法确定各指标权重,并构建农业生态经济协调度模型。结果]通过对广东省农业生态经济协调发展水平进行分析,发现不同区域的农业生态经济协调水平存在较大差异。随着时间的推移,广东省各地区的农业生态经济协调发展水平都有所提升;在空间上,粤东区和粤北区发展相对缓慢,协调发展水平相对较低,珠三角区协调发展水平最高。结论]预测粤东区未来几年可能仍处于中等协调发展水平,粤西区未来几年将很快进入优质协调发展水平,粤北区可能即将进入中等协调发展水平,珠三角区域内的城市将会逐渐进入优质协调发展水平。为了促进广东省农业生态经济的协调快速发展,建议政府根据各经济区的优势,因地制宜发展生态经济。

ANALYSIS OF TEMPORAL AND SPATIAL VARIATION OF AGROECOLOGICAL ECONOMY IN GUANGDONG PROVINCE

Agricultural eco economic system is a complex combining agricultural ecological development and economic development. The research is intended to study the temporal and spatial changes of agricultural ecological economy, so as to provide the theoretical basis for the sustainable development of agricultural ecological economy in Guangdong Province. The evaluation index system was constructed by consulting the literature, the weight of each index was determined by entropy weight method, and the coordination degree model of agricultural ecological economy was constructed. The results showed that there were great differences in the level of agricultural eco economic coordination in different regions through the analysis of the level of agricultural eco economic coordination in Guangdong province. With the passage of time, the level of coordinated development of agricultural eco economy in various regions of Guangdong province had been improved. In space, the development of eastern Guangdong and northern Guangdong was relatively slow, the level of coordinated development was relatively low, and the level of coordinated development in the Pearl River Delta was the highest. Based on the results, it is predicted that the eastern part of Guangdong may still be at a moderate level of coordinated development in the next few years, the western part of Guangdong will soon enter the level of quality coordinated development in the next few years, and the northern part of Guangdong may soon enter the level of moderate coordinated development. The cities in the Pearl River Delta region will gradually enter the level of high quality coordinated development. In order to promote the coordinated and rapid development of agricultural ecological economy in Guangdong province, it is suggested that the government should develop the local ecological economy according to the advantages of each economic zone.
