【摘要】：在当今农业快速发展的时代背景下,畜禽排泄物作为新型的、可被利用的珍贵资源并没有得到充分有效的处理和利用,这既浪费了可用于循环再利用的资源,又对畜禽养殖业与生态环境造成了双重影响。根据当前黑龙江省对于畜禽排泄物进行处理的程度与进展,因在出产农作物的过程里,化肥正逐渐替代有机肥,畜禽养殖户对畜禽排泄物的回收利用价值低估甚至不清楚等,这些原因使得大部分的畜禽排泄物不能够得到很好的处理与利用,造成了大面积的农业污染,这对于发展绿色畜牧业是十分不利的。因此在当前的可持续发展形式下,十分需要政府及养殖主体提高对畜禽排泄物综合利用的重视程度。对畜禽排泄物的处理与综合利用问题进行研究具有理论和实践双重意义,通过本文的研究与分析将进一步充实和发展循环经济理论。在当今提倡重视环境保护的形势下,畜禽排泄物的污染问题应受到重视,不科学合理的对畜禽排泄物进行处理将会对人类健康与生态系统的平衡造成不利影响。本研究有利于促进生态的可持续发展,更能促进黑龙江省畜牧业持续、健康、稳定发展。畜禽排泄物的综合利用对于农业发展、环境保护有着重要作用。黑龙江省作为中国畜禽养殖的主要省份之一,目前在畜禽排泄物的综合利用方面还处于初步发展阶段,尚存在一些制约因素,相关理论还不完善,对畜禽排泄物综合利用水平没有进行过系统评价。目前黑龙江省正大力进行畜禽养殖方面的环境整治工作,但实际养殖过程中畜禽的排泄物处理模式仍旧较为单一,以还田模式为主,再循环、再利用程度较低。基于循环经济的理念,为更好的发展黑龙江省绿色畜牧业,需要将关注点放在黑龙江省畜禽排泄物的综合利用上,畜禽排泄物综合利用水平将影响黑龙江省的农业经济与生态可持续发展。本论文在研究内容上,首先研究了黑龙江省畜禽排泄物的污染与综合利用情况,通过对畜禽排泄物及其污染物产生量进行计算,提出畜禽排泄物综合利用的必要性,并进一步运用因子分析与聚类分析的方法,对黑龙江省畜禽排泄物综合利用水平进行了评价,最后在借鉴国外先进经验的基础上,提出了提高综合利用水平的相关建议。
[Abstract]:Under the background of the rapid development of agriculture, livestock and poultry excreta, as a new type of precious resources that can be used, has not been fully and effectively treated and utilized, which not only wastes the resources that can be used for recycling, And the livestock and poultry breeding and ecological environment caused a dual impact. According to the current level and progress of livestock and poultry excreta disposal in Heilongjiang Province, because chemical fertilizers are gradually replacing organic manure in the process of producing crops, livestock farmers underestimate or even do not know the value of recycling livestock and poultry excreta. These reasons make most of the excrement of livestock and poultry can not be treated and utilized well, which results in a large area of agricultural pollution, which is very unfavorable to the development of green animal husbandry. Therefore, under the current sustainable development form, it is very necessary for the government and the main body of aquaculture to pay more attention to the comprehensive utilization of livestock and poultry excreta. It is of both theoretical and practical significance to study the disposal and comprehensive utilization of livestock and poultry excreta. Through the research and analysis of this paper, the theory of circular economy will be further enriched and developed. The pollution of livestock and poultry excreta should be paid attention to under the situation of advocating environmental protection. Unscientific and reasonable disposal of livestock and poultry excreta will have adverse effects on the balance between human health and ecosystem. This study is beneficial to promote the sustainable development of ecology and the sustainable, healthy and stable development of animal husbandry in Heilongjiang Province. The comprehensive utilization of livestock excreta plays an important role in agricultural development and environmental protection. Heilongjiang Province, as one of the major provinces of livestock and poultry breeding in China, is still in the initial stage of development in the comprehensive utilization of livestock and poultry excreta. There are still some restrictive factors, and the relevant theories are not perfect. The comprehensive utilization level of livestock and poultry excreta has not been systematically evaluated. At present, Heilongjiang Province is vigorously carrying out the environmental improvement of livestock and poultry breeding, but the waste disposal mode of livestock and poultry is still relatively single in the actual breeding process, mainly in the mode of returning to the field, recycling, and low degree of reuse. Based on the concept of circular economy, in order to better develop Heilongjiang Province's green animal husbandry, we need to focus on the comprehensive utilization of livestock and poultry excreta in Heilongjiang Province. The comprehensive utilization level of livestock and poultry excreta will affect the sustainable development of agricultural economy and ecology in Heilongjiang Province. In this paper, firstly, the pollution and comprehensive utilization of livestock and poultry excreta in Heilongjiang Province were studied, and the necessity of comprehensive utilization of livestock and poultry excreta was put forward by calculating the amount of livestock and poultry excreta and its pollutant production. The comprehensive utilization level of livestock and poultry excreta in Heilongjiang Province was evaluated by the methods of factor analysis and cluster analysis. Finally, based on the advanced experience of foreign countries, some suggestions were put forward to improve the comprehensive utilization level.
