安徽省沿淮地区农林复合经营模式的研究

采用定量的方法对几种农林复合经营的模式进行研究,直接测算各模式的经济指标、综合分析和评价经营的效果。研究结果表明：选择枣树和香椿与农作物进行混作的种植模式,比单纯种植农作物的经济效益可提高55.4%～63.8%。对于杨树等生长较快的树种,只能在造林后3a以内在林下间种农作物,由于树冠对于阳光的遮挡影响,可以选择林牧结合的经营模式,利用林内杂草放养鹅等禽类,既可获得较好的经济收益,又可以降低林木抚育管理的成本,促进树木的快速生长。

Research on Agroforestry Management Models in Areas along Huaihe River in Anhui Province

Several agroforestry models were studied with a quantitative method for measuring results in economic indicators, comprehensive analysis and evaluation of management. The results show that,mixed models for selecting Jujube and Toon with the cultivation of crops could improve the economic benefits of 55. 4 - 63. 8% than simply growing crops. For the poplar and other fast growing tree species,because of tree canopy for sun,farmland under tree planted crops only within 3 years, but could choose animal husbandry,such as geese and other birds class ,which not only got better economic benefits,but also reduced the cost of the management of forest and promoted the rapid growth of trees.
