Agroforestry Economic Evaluation Of Different Allocation Structure

Development of plain forestry, to build a good plain farmland shelterbelts, for improving the field microclimate, soil, improve soil fertility, reduce the dry heat wind, late spring, frost, dust storms and other climate disasters, the harm has a special role. To develop in the plain areas of farmland shelterbelt in improving agricultural production and improve the economic efficiency of cultivated land and increase their income, and increase their enthusiasm for forestry development and awareness, to achieve sustainable forestry development, is of great significance. In agroforestry research and practice, and more from the forest belt of the protective benefit of the configuration, very little cost involved. In order to meet the needs of the market economy, plain forestry must play its full and balanced comprehensive benefits. Forest growth cycle is longer, years or even decades, a single forest structure, severely constrained economic efficiency of forestry. Should therefore be a reasonable adjustment to the configuration within the shelterbelt to ensure the ecological benefits in the premise, so that maximum economic benefits.According to the characteristics of plain and trends of forestry objective needs of economic benefits has become an important part of the comprehensive benefits of shelterbelts, Based on the configuration of Henan Province Xingyang different forest structure model investigation, Applied Economics and the multi-objective decision-making Grey theories and methods, from a quantitative point of view of its comprehensive economic evaluation and optimization of mode selection. The results showed that: poplar, ginkgo, pepper, Salix integra, Amorpha fruticosa, day lily, soybeans, combination of three-dimensional configuration of the forest (Modeâ…¡) was better than that of its economic structure of poplar (Mode I) The forest belt, the former 3.38 times the net present value of the latter, poplar, pomegranate, Amorpha fruticosa, day lily, soybeans and other configuration structure (modeâ…¢), and higher efficiency. Net present value is the mode l of 3.14 times. That is: configure the structure of Luotong village the economic performance of the highest, followed by village Guandimiao, the simple structure of Huaixi village the economic is minimumInnovation of this paper in the following three aspects: (1) use of cash flow analysis, the form lists the forest structure of the complex input and output so as to give a production period, the costs and benefits at a glance, a more convenient analysis; ( 2) NPV, B / C, IRR, N / K combined with a four economic evaluation of its economic indicators, so that the results more convincing; (3) different target given different weights, so that multi-objective decision method of Grey more reasonable and more effective method...
