Exploration Of Integratedi System Configuration Of Agrculture-forest-animal Husbandry On A Sustainable Basis In Mu Us

In this paper,the regional model of Fengsha grassland ecological region in Shaanxi province was selected as the research area,and the distribution model of agroforestry and animal husbandry system in Shenmu county was explored by literature analysis,questionnaire survey and data analysis.The status quo,the landscape pattern analysis and the status quo of agriculture,forestry and animal husbandry development to study the main problems in the process of agriculture,forestry,animal husbandry and distribution,and put forward rationalization proposals,with a view to follow-up Shenmu county related research to provide reference.Research indicates:(1)The total cultivated area of Shenmu county showed a steady upward trend,and the agricultural output value continued to increase,which increased from 13.69% in 2009 of the total output value of agriculture,forestry,animal husbandry and fishery to 29.23% in 2015,but the total agricultural land area decreased slowly,explain the effectiveness of science and technology investment;forestry ecological construction after returning farmland to forest and grass project,the implementation of arable land greening project,forest area continued to increase to "six in one" artificial sand fixation vegetation rapid recovery technology as the representative of a number of dryland afforestation technology and the area of effective irrigation and drought and waterlogging has been increased and remained stable,which is conducive to the construction of effective farmland-shelterbelt allocation pattern.(2)The landscape pattern index was calculated by two remote sensing data,it is shown that the landscape pattern is simple,the degree of fragmentation is high,the landscape heterogeneity is enhanced,the landscape uniformity is increased,and the secondary industry has significant effect on the local landscape pattern.(3)The number of animal husbandry and aquaculture industry in Shenmu County showed an increasing trend,and gradually formed and promoted to "demonstration households + family ranch + breeding area + leading enterprises" development model to promote the local animal husbandry dairy cattle,pig,cashmere sheep,sheep 4 Industry development,for the local farmers to provide strong protection of income.The per capita income and expenditure of farmers increased from 0.95 in 2009 to 1.03 in 2015,indicating that the current pattern of agriculture,forestry and animal husbandry can bring some economic income to farmers and improve the living conditions.(4)In the study of vegetation restoration and ecological system construction,most of the measures have been taken to adapt to climate change and help to improve the ability of local agroforestry and animal husbandry system and the sustainable development of agroforestry and agroforestry ecosystem mode.(5)The model of sustainable agroforestry and animal husbandry complex ecosystems in Mu Us sandy land,which is typical of Shenmu,focuses on the rational use of water and soil ecological agriculture model,the cultivation mode of feed processing as the link,To increase the protection and support mode of agriculture,forestry and animal husbandry under the guidance of the government policy,and the vegetation restoration mode of ecological economy should be constructed,and the ecological and vegetation restoration should be closely integrated with the economic benefits of agriculture,forestry and animal husbandry.
