A Three-Dimensional Model for Special Ecological Agricultural System (SEAS) in the Southeast Fujian Province

Although the southeast Fujian Province has favorable bio-climatic conditions, traditional farming models are limited in effective exploitation of agriculture related resources and have deteriorated the agricultural environment. After analyzing the conditions at Maping town, we designed a three-dimensional model, special ecological agricultural system (SEAS), at Maping town. The SEAS has been practiced for three years and results show that the SEAS more efficiently utilizes local time and space resources and gains more econo- mic, ecological and social benefits. Thus, the SEAS has been considered as an optimal model for sustainable utilization of agricultural resources.

Study on Consistent Agricultural Compensation Standards for Ecosystem and Ecological Value

Chinese and international studies on agricultural ecological compensation standards fall into two categories:While some focus on the cost of ecological protection,others proceed from the value of ecological services.Cost and value are two aspects of an integrated input-output system,but most existing studies on both types of compensation standards are independent of each other.Drawing upon the reasonable elements from both types of studies to overcome each other’s one-sidedness,this paper has created a“model of consistent compensation standards for the ecosystem and ecological value,”integrating the research approaches for both types of compensation standards under the same analytical framework.Through the application and analysis of this model,this paper has verified the model’s theoretical and practical significance in correcting the one-sidedness of each type of research.The principles and methodologies for creating the model may be further extended to research on agricultural ecological compensation standards under different conditions.In some circumstances,the ability of relatively redundant resources to create ecological value is overlooked.To address this problem,this paper employs a linear programming(LP)sensitivity analysis instrument to correct the model’s initial optimal solutions and arrive at consistent compensation standards that satisfy the consistency between ecosystem and ecological value,thus perfecting the theoretical and methodological system created by this paper for research on agricultural ecological compensation standards.

County urbanization,agricultural servitization,and agricultural eco-efficiency:Statistical verification based on Chongqing

Agricultural ecologicalization is an important starting point to promote sustainable and high-quality development of agriculture.Based on the panel data of 37 districts(counties)in Chongqing from 2004 to 2019,the DDF-GML index method is used to measure the agricultural ecological efficiency of Chongqing.Based on the analysis of the interaction mechanism of urbanization,agricultural service,and agricultural ecological efficiency,with the help of the PVAR model verifies the relationship between the three.The study found that urbanization,agricultural service,and agricultural ecological efficiency have significant inertia effects and path dependence,especially agricultural ecological efficiency can provide more than 90%of its variance contribution,while urbanization and agricultural ecological efficiency have a significant impact on agricultural ecological efficiency.The influence will become weaker and weaker over time,obeying the law of diminishing margins.Therefore,to promote the development of agricultural ecologicalization,we must rely on the clean,green,and ecological development of agricultural production itself.At the same time,we also need to further improve the urbanization and agricultural service modernization system to maximize the benefits of agriculture.

Implications of agricultural success in the Yellow River Basin and its strategy for green development

The Yellow River Basin is an important food production area and an ecological challenge for China, where environmental protection and water scarcity are the major constraints. For the upper reaches of the Yellow River Basin,optimizing the adoption of chemicals in agricultural production and integrating crops with livestock are the key strategies for protecting the eco-environment.For dryland agriculture in the middle and upper reaches, this study summarizes four aspects of efficient precipitation techniques in terms of collection,storage, conservation, and use, which have greatly improved crop yields and supported dryland crop production. Irrigated agriculture in the middle and lower reaches is the core area of China's grain production, where the area under water-saving irrigation reached 13.0 Mha in 2018, greatly improving water use. Compared with 1998, cereal production in 2018 increased by 62.2 Mt under similar total water withdrawals(49.7 billion to 51.6 billion m~3),and the annual soil erosion at the Tongguan Hydrological Observatory reduced by 584 million m~3 in 2018, achieving great success in environmental protection and efficient water use. The Chinese government has set a goal for the Yellow River Basin to become the national leader in environmental protection and efficient water use by 2035. Such a high demand requires the combined efforts of the whole community, as well as the adoption of new technologies,coordinated basin-wide development, and adequate policy support.

Relationship Between Agriculture and Ecological Deterioration,Restoration and Reconstruction in Loess Plateau Areas of Northwest China

A comprehensive analysis was conducted on the current situation as well as historic succession processor agriculture and ecological conditions in Northwest China, in particular in the Loess Plateau, by means of a inter-disciplinary approach of ecology, agro-geohistory, and agronomy. It was concluded that the fundamental causes responsible for the ecological deterioration, signed by the poor agro-productivity and serious soil erosion, had been the extensive cropping system by ever-increasing reclamation on semi-drought slope land, where initiated a natural vegetation of brushy grasses with sparse trees, thus suitable only for animal husbandry. Based on an identification of specific actual status of China, several countermeasures of correctly dealing with the relationship between agricultural development and the ecological restoration and reconstruction were proposed, including to get breakthrough first in the transection area by means of the rational use of resources and the raising of agro-system productivity, to promoting 'water conservancy-type ecological agriculture' through the radical shift of traditional production pattern, and the adoption of a policy of proper degree of grain self-reliance, as well as to construct livestock industry base in Northwest China.

Research on the Development Model of Ecological Agriculture in Loess Hilly-Gully Region of Northern Shannxi, China

On the Loess Plateau of China, facing the vulnerable environment, local people have to try their best to guarantee the security of food, and at the same time, to control the most serious soil erosion in the world. The paper introduces two typical models of ecological agriculture: ecological agriculture with commodity and agri- culture with soil and water conservation. According to the local natural condition, the model of eco-agriculture with commodity could be characterized by the structure of “agriculture-byproduct”, “agriculture-fruit” or “agri- culture-forestry-husbandry”. The development of agriculture with soil and water conservation has decreased the soil erosion rate from 12,184 ton/km2 in 1980 to 458.4 ton/km2 in 1999, while the farmers’ income has increasingly risen. Analyses on the two models’ benefits both in terms of ecological and agricultural economy show that there is a great possibility to construct or restore good eco-environment with comprehensive control in the hilly-gully area of north Shannxi. Further more, the paper points out the potential problems of foodstuff production and stockbreeding development in forming ecological agriculture and eco-environmental restoration.
