湖南紫色土山丘区农业复合模式的优化与生态经济效应
Optimization and Ecological & Economic Effects of Complex Agricultural Modes in Hunan Purple Soil Hill Areas
摘要
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.关键词
