Research On The Agriculture Layout Based On The Niche Theory In Lihuagou Village Jintang Xian

Agriculture as the primary industry of the national economy,what is related to people’s livelihood and social harmony,it has the important strategic significance on the sustainable development of agriculture and social economy.As the focus poverty village,and face the big background of China ecological agricultural development,The most urgent means of promoting its economic level growth is the development of first industry,agricultural.Using ecological theory to research Lihuagou Village agricultural layout,it can help to find most for Lihuagou Village domain status and economic efficient development of ecological agricultural development strategy,widened agricultural development way,pull villagers economic increase,improve village domain overall economic level,speed up the pace of liberating from poverty.After carding literature both at home and abroad,and Understanding the principles and connotations of the agricultural layout and niche theory,I had analysised the factors of affecting the layout,including soils,topography,climate,agriculture,economic development potential and the ecological environment of agriculture,while testing the soil pH,organic matter and effective detection of nitrogen,phosphorus and potassium.in Sichuan Provincial Academy of agricultural sciences in analysis and test center.In this paper,based on niche theory,through on collecting the information of Lihuagou Village,and reality of research and the depth access,I put 21 groups as the evaluation units,selected Organic matter content,and effective soil thickness,and hydrolyzable nitrogen,as 17 evaluation indexes,according to agricultural niche construction principles,structured the "agricultural layout" index system to measure the niche.Then,using the analytic hierarchy process(AHP),respectively determine the weight of the system layer and target layer,Introducing model,using SPSS19.0 and EXCEL for data processing,the results show that:1.Lihuagou Village "agricultural layout" ecological values are divided into three levels,namely: high value areas,namely As>0.4;,0.3<As<0.4;low value areas,namely As<0.3.2.Group four of niche value of 0.687 is the highest in the village,located in the Central village area;group eight of niche value of 0.242 is the lowest in the village,located in the East Village area.In General,the group number of distribution in the value area of the sub-regional are more than low values.3.According to the results,combined with Lihuagou Village status,concluded that current agricultural layout is divided into four blocks: agro-tourism integrated development area,the fruit and vegetable industry core,natural eco-agriculture in agricultural development zones and conservation areas.Focus on the development of agro-tourism,agro-tourism integrated development district,supplemented by farming;fruits and vegetables grow core focus on the development of fruit and vegetable growing;natural farming zone focused on the transformation of agricultural development,develop natural farming techniques ecological conservation areas focused mainly on the protection of ecological environment of agriculture,appropriate farming and tourism.
