Exploring the effective and efficient path of agricultural carbon emission reduction in Henan Province is of great significance to optimizing the strategic layout of China's agricultural emission reduction and carbon sequestration.Accordingly,the agricultural carbon emissions of each county were measured scientifically and then the spatial measurement model was utilized to clarify the spatial and temporal evolution trend and spatial effect mechanism of agricultural carbon emissions based on the county data of Henan Province from 2010 to 2020.The results showed that:(1)in 2020,the total agricultural carbon emissions were 134.7274 million tons,with the high distribution in the southeast and low distribution in the northwest;(2)the spatial dependence of agricultural carbon emissions showed a four-stage trend of fluctuating down-continuing up-plummeting-fluctuating up again,and the spatial heterogeneity was dominated by low-low agglomeration,followed by high-low agglomeration;(3)there was an inverted U curve relationship between the level of agricultural economic development and agricultural carbon emissions.The increase in the level of agricultural mechanization and urbanization rate significantly reduced agricultural carbon emissions.The opposite was true for the financial support for agriculture,the income level of rural residents and the structure of the agricultural industry;(4)in terms of spatial spillover effects,the increase in the level of agricultural development in neighbor counties first increased and then decreased agricultural carbon emissions in Henan Province.The mechanization level and urbanization rate of neighbor counties reduced agricultural carbon emissions in Henan Province,and the opposite was true for the income level of rural residents and the scale utilization of agricultural land. 展开更多

Financial support to agriculture is the main driving force to increase farmers' income. This paper applied the evaluation DEA (Data-embrasing Analysis) method to evaluate the effectiveness of financial support to agriculture from 1990 to 2005. It is found that the trend of the financial support to agricultural effectiveness in China presented a downward trend in recent years. The results showed that the overall trend of the financial support to agriculture in China wasn't high, and some corresponding proposals were put forward to optimized. 展开更多

But there exist some obstacles in agricultural technique promotion. Some translators haven't paid attention to their needs and education levels of target readers in agricultural promotion that proves to be obscure translation rather than simple farming method. This paper conducted an investigation on modal values based on Halliday's systematic modality theory. Corpus quantitative research approach was used in the hope of gaining more insights into agriculture technique English. A comparative analysis was made between Brown Corpus and agricultural English Corpus (AEC) which contains 400 000 words, summarizing the differences in application of modal verbs across the two corpora. This study aimed to probe into modal values in practice of agricultural technique promotion texts in a way, which could be better understood by readers of target language. 展开更多

Agriculture plays a duet role in climate change. It has been a major source of greenhouse gases to the atmosphere. It is also one of the sectors most vulnerable to the risks and impacts of global climate change. This paper first indentified the mitigative and adaptative options and potential in agriculture, then addressed the integrated analysis of mitigation and adaptation and its benefits for agriculture. Finally, it discussed the implications to Chinese agriculture in dealing with the global climate change. 展开更多
