The Research Of Anhui Low-carbon Crop Farming Based On Carbon-footprint

Nowadays, environment problem is becoming more serious, and is a main topic of the country. Environmental disaster has made people to evaluate the current development modes. Developing low carbon economy is a efficient way to reduce green house gas and improve the environment. So it is of great importance to study the impact of carbon emission on the development of low-carbon agriculture. Anhui is an agricultural province, of which the traditional extensive farming increasingly highlights the problems. It is imminent to develop the low-carbon agriculture.This paper is about to study the low-carbon development of crop farming in Anhui province based on the perspective of carbon footprint. This paper has three parts. The first part has three chapters, including chapter one. chapter two and chapter three. This part is focused on background, frame, methods, the research status at home and abroad and also the relevant theoretical literatures, which lay a foundation for subsequent parts of the paper.The second part is the most important one. It has two chapters. Chapter four describes the current situation of agriculture and farming in Anhui, revealing the existing problems and giving the suggestions. Chapter five analyzes regional carbon emissions, carbon absorption and carbon footprint. In order to study the regional differences of carbon footprint,the paper divides Anhui province into 5 regions which is Huaibei plain, Huainan hillock area, polder area, western mountain area and southern mountain area by climate characteristics, cultivation measures, crop planting patterns and division standard by Anhui academy of agricultural sciences. By searching and sorting statistical yearbook data of Anhui, the paper calculates the 5 regions of carbon emissions, carbon absorption and footprint from year 2003 to 2012.The result shows that the carbon emission and absorption of 5 regions has increased yearly. The absorption is greater than emission. Huaibei plain is on the top list of carbon emission and absorption, followed by hillock area. The carbon footprint of 5 areas has changed steadily since the decrease in 2003, but it has a tendency to rise on the whole. Due to the regional cultivated land area are greater than carbon footprint of the same period, so all regions are carbon surplus, namely that the carbon footprint is in the range of ecological carrying. Last, in order to explore the influence factors of carbon footprint, the paper builds panel data model through reference of Cobb-Douglas production function to measure the empirical analysis of the influence. The paper uses carbon absorption (y) as dependent variable and crop planting area (land), labor, fert. machine and planting structure(s) as independent variables to study the influence of 5 indices in net carbon absorption. The result shows that the index of land, fert and s has significant effects on net carbon absorption, while labor and fert have negative impacts. Besides, the land has the biggest elasticity among all the indices.The third part of the paper only has one chapter. Chapter six has put forward the corresponding countermeasures and suggestions according to the results of theoretical and empirical research. For example, to reduce the conventional material inputs such as fertilizers and pesticides, implement the farm mechanization and enhance food production, reduce the surplus Labor, improve agricultural technology innovation and management level, develop new agricultural model, such as co logical agriculture and circular agriculture.
