气候变化是当前人类社会面临最为严峻的全球环境问题之一。虽然关于气候变化成因和影响的学术争论一直存在，但不可否认，大气中温室气体浓度的增加是导致这一变化的重要因素。第二、第三产业是碳排放的主导部门，但快速发展的农业也是加速气候变化的重要诱因。在农业碳排放量持续上升、温室气体减排诉求日趋强烈的今天，发展低碳农业已刻不容缓。但同时，我们对低碳农业理念有多少了解？这些年我国低碳农业发展处于什么水平、变化轨迹与发展趋势如何？省域间低碳农业效率存在何种差异、是否具有空间收敛性？导致我国低碳农业生产率变动的关键性因素是什么？很显然，对这些问题进行有效解读将有助于增进我们对中国低碳农业发展现状及其基本特征的宏观认知，进而理论与实际结合，构建更为合理的政策体系，为加快推进我国低碳农业发展步伐、切实践行生态文明建设方针奠定坚实基础。

有鉴于此，本书以低碳农业为研究对象，首先系统梳理了国内外相关文献，对其所涉及的一些重要概念及相关理论进行了回顾与总结，以确保研究根基。然后，对我国农业碳排放/碳汇量进行了全面核算并分析了其时空特征，一方面增强了我们的宏观认知，更为重要的是，为低碳农业生产率的测度提供了数据支撑。在此基础上，基于农业碳排放、农业碳汇以及农业投入产出数据，系统核算了我国低碳农业生产率，并深入探究了其增长源泉、时序演变规律、区域分异特点、动态演进及收敛性。紧接着，分析了影响我国低碳农业生产率增长的宏观因素与低碳农业技术采纳的微观机理，从中探寻出了导致低碳农业水平发生变化的关键动因。最后在总结并借鉴国外低碳农业发展经验的基础上，有针对性地提出了对策建议，以期为我国更好地践行生态文明理念、推进低碳农业发展提供必要的数据支撑与理论依据。具体而言，本书研究内容主要分为文献综述与理论基础（第一、第二章）、农业碳排放/碳汇现状分析（第三章）、低碳农业生产率测度及其时空特征分析（第四、第五章）、低碳农业生产率与技术采纳的影响因素分析（第六章）、低碳农业发展政策体系构建（第七、第八、第九章）五大部分。

Climate change is one of the most serious global environmental problems facing human society. While there has been academic debate about the causes and effects of climate change, it is undeniable that the increase in greenhouse gas concentrations in the atmosphere is an important factor in this change. The secondary and tertiary sectors are the leading contributors to carbon emissions, but fast-growing agriculture is also an important contributor to accelerating climate change. Today, when agricultural carbon emissions continue to rise and the demand for greenhouse gas emission reduction is becoming stronger, it is urgent to develop low-carbon agriculture. But at the same time, how much do we know about low-carbon agriculture? What is the level of low-carbon agricultural development in China in recent years, what is the change trajectory and development trend? What are the differences in the efficiency of low-carbon agriculture between provinces, and is it spatially convergent? What are the key factors leading to changes in China's low-carbon agricultural productivity? Obviously, an effective interpretation of these issues will help enhance our macro understanding of the development status and basic characteristics of low-carbon agriculture in China, and then combine theory and practice to build a more reasonable policy system, laying a solid foundation for accelerating the pace of low-carbon agricultural development in China and implementing the policy of ecological civilization construction. In view of this, this book takes low-carbon agriculture as the research object, first systematically combs through the relevant literature at home and abroad, and reviews and summarizes some important concepts and related theories involved in it to ensure the foundation of research. Then, the carbon emissions/carbon sinks of China's agriculture are comprehensively accounted for and their spatial and temporal characteristics are analyzed, which enhances our macro understanding on the one hand, and more importantly, provides data support for the measurement of low-carbon agricultural productivity. On this basis, based on agricultural carbon emissions, agricultural carbon sinks and agricultural input-output data, the productivity of low-carbon agriculture in China is systematically calculated, and its growth source, temporal evolution law, regional differentiation characteristics, dynamic evolution and convergence are deeply explored. Then, the macro factors affecting the productivity growth of low-carbon agriculture in China and the micro mechanism of the adoption of low-carbon agricultural technologies were analyzed, and the key drivers leading to the change of low-carbon agriculture level were explored. Finally, on the basis of summarizing and learning from the development experience of low-carbon agriculture abroad, countermeasures and suggestions are put forward in a targeted manner, in order to provide necessary data support and theoretical basis for China to better practice the concept of ecological civilization and promote the development of low-carbon agriculture. Specifically, the research content of this book is mainly divided into five parts: literature review and theoretical basis (chapters 1 and 2), analysis of the status quo of agricultural carbon emissions/carbon sinks (chapter 3), measurement of low-carbon agricultural productivity and its temporal and spatial characteristics (chapters 4 and 5), analysis of influencing factors of low-carbon agricultural productivity and technology adoption (chapter 6), and construction of low-carbon agricultural development policy system (chapters 7, 8 and 9).（AI翻译）
