Economic Analysis On Disposing Livestock Excrement In Heilongjiang Province

In recent years, livestock husbandry in Heilongjiang Province has developed rapidly, which has been the most active growth and pillar industry. In 2006, the livestock husbandry output value has reached 48.07 billion yuan, 4.2 percent more than last year, 34.64 percentage of the total agricultural output value. Livestock income of each person of rural areas is 701 yuan. The placement of suplus laborers by livestock husbandry is 2.4 million. 12.5 million tons of grain has been converted, which realizes 6 billion yuan value added benefits. The dominant position of livestock husbandry has been further improved. Heilongjiang Province is becoming an livestock husbandry province from big to strong. However, with the expansion of the scale of livestock and poultry breeding, the amount of livestock waste is increasing. The pollution of livestock husbandry is becoming seriously. Livestock waste is a huge source of pollution. If we handle improperly, a lot of nitrogen, phosphorus will lose, and then there will be air pollution, water pollution, soil pollution and crop pollution. More serious, it will destroy ecological environment, threat human health, induce none sustainable development of livestock husbandry.Researching on disposing livestock excreta has theoretical and practical significance. On one hand, disposing livestock excreta belongs to Circular Economy. Analysis on livestock breeding environmental carrying capacity and cost-benefit is from a new view to research on disposing livestock excreta, which will enrich and develop cycle of economic theory. In the mean time, livestock environmental theory is a new field when livestock husbandry develop into a certain stage and some social economic conditions come up. The research is just on the basis of environmental protection, which will enrich and develop the content of livestock environmental theory; On the other hand, the problem of disposing livestock excreta is an important part of environmental protection. If we handle improperly, livestock excreta will threaten people'health, even destroy the balance of ecology system. This research will sound the alarm for our society, making people be more concerned about their living environment. This is beneficial for the sustainable development of ecology, and will promote livestock husbandry develop sustained, healthy and stable.On this basis, the thesis analyzes the pollution situation of livestock husbandry in Heilongjiang Province, calculates and forecasts the livestock breeding environment carrying capacity of Heilongjiang Province, analyzes cost and income of energy conversion. On the basis of learning from foreign experience, proposes up targeted, effective countermeasures. The thesis is divided into two sections. The first section is theory. It mainly elaborates background, purpose and meanings, and introduces theoretical foundation of livestock husbandry pollution handling, including ecological and economic theory, circulation economic theory and environmental carrying capacity theory, which provides scientific basis for the thesis. This part is consisted of one and two chapter. The second section is practice. It mainly analyzes the experience of disposing livestock excreta of foreign countries, analyzes and forecasts on carrying capacity of livestock breeding environment, analyzes cost-benefit of disposing livestock excreta. At last, it puts up the countermeasures. This section is consisted of three, four, five, six, seven and eight chapter.The thesis takes empirical and normative analysis, qualitative and quantitative analysis methods to study the related theories of livestock excreta disposing. Combining with the accessible data, by using analysis method and grey forecast model, it analyzes and forecasts on livestock breeding environmental carrying capacity. On the basis of cost-benefit method, it analyzes the cost and income of energy conversion.The creative results of the thesis are as follows:(1) Innovation on research perspective Establishing economic calculation method of livestock excreta pollution and carrying on cost-benefit analysis of disposing is from a new view to study livestock excreta pollution problem, which will enrich and develop circulation economic theory.(2)Innovation on research content and method By using analysis method and grey forecast model, the thesis analyzs and forecasts the level of livestock excreta pollution and the limits that the environment can bear, which will provide basis to government for pollution control of livestock husbandry environment.
