基于能值分析的安徽省农业生态效率研究

Research on agricultural ecological efficiency in Anhui Province based on energy value analysis

农业发展受生态环境的影响较大,但长久以来缺少较为统一的评价标准。为推动农业可持续发展,本研究引入生态学中能值分析的理论和方法,通过划分、界定生态农业系统各子系统,深挖其物质运移特征,对各项物质投入产出进行能值化,基于能值分析对相关生产地区进行农业生态效率测算,并对测算结果进行比较分析。研究方法可为农业生产过程中各生产要素的投入提供数据支撑,提高耕地利用综合效率,促进农业生产发展。

Agricultural development is greatly affected by the ecological environment,but there has been a lack of unified evaluation standards for a long time.In order to promote the sustainable development of agriculture,this study introduces the theory and method of energy value analysis in ecology,divides and defines the subsystems of ecological agricultural system,deeply explores their material transport characteristics,quantifies the energy input and output of various materials,measures the agricultural ecological efficiency of relevant production areas based on energy value analysis,and compares and analyzes the measurement results.This research method can provide data support for the input of various production factors in the agricultural production process,improve the comprehensive efficiency of cultivated land utilization,and promote the development of agricultural production.
