摘    要:湖南有紫色土山丘146.7万hm2,区内人口达800多万人。紫色土山丘地形以丘岗地为主,土壤含磷、钾、钙等矿质养分较多,质地偏壤,有利于发展农业生产,但紫色土山丘易旱,土壤有机质和氮素含量较少,水土流失严重,农业生产单一,农业经济效益不高。本文通过对湖南省紫色山丘区现有的农业复合模式进行全面调查和总结,在科学试验的基础上,选取总产值、纯收入、内部收益率三项指标,采用层次分析法,从8个一级复合模式下的30个二级复合模式中,对其中16个应用面积较大的林农间种复合模式进行综合分析,结合农产品比较优势和生态效益,遴选了一批经济效应、生态效应显著的模式。完善优化了4个农牧渔复合模式,经过实施和应用,取得了重大经济效益和生态效益。

关 键 词:紫色土山丘区  林农间作  农林牧渔结合  模式优化  生态效应  经济效应

Abstract:Hunan has the purple soil hills of 1.467 million hectares which has a population of over 8 millions.Purple soil hilly is conducive to the development of agricultural production,because its terrain mainly to the hills,more phosphorus,potassium,calcium and other mineral nutrients,texture partial soil.But its agricultural production is onefold,and agricultural economic benefits is not high,because of its easy drought,soil organic matter and nitrogen content of less,soil erosion severe.On the foundation of scientific test,this article select the three indexes of total output value,net income,internal rate of return through a comprehensive survey and summary of the existing agricultural complex mode in the purple soil hill areas of Hunan Province.as well as comprehensive analysis 16 composite model planting between forestry and agriculture of applications larger area,using analytic hierarchy process from 30 second class composite mode under 8 first class composite model,It also select a number of complex mode,which its economic effects and ecological effects are remarkable combining agricultural products of comparative advantage and ecological benefits.Finally,it improved and optimized four composite model of agricultural,animal husbandry and fisheries and made significant economic and ecological benefits through implementation and application.
Keywords:purple soil hill areas  planting between forestry and agriculture  combination of agricultural  forestry  animal husbandry and fisheries  mode optimization  ecological effects  economic effects
