豫东黄河故道农林复合生态模式经济效益分析

以商丘市梁园区为例,对豫东黄河故道的农林复合生态模式进行了调查研究。结果表明在黄河故道发展农林复合生态系统可以为当地创造一定的经济与生态效益。根据研究地区的自然与社会环境条件,可以发展以下几种农林复合生态模式:①林农复合生态模式,在幼龄林中种植小麦、油菜等喜光作物;②林药复合生态模式,树龄达到4年以后在林下种植耐阴的药用植物;③林牧复合生态模式,林冠完全郁闭之后在林下养鸡等。

Evaluation of Economic Benefits on the Modes of Agroforestry in the Original Channel of the Yellow River in the East of Henan Provience

With the example of Liangyuan district of Shangqiu city located in the east of Henan province,the economic benefits of several categories of agroforestry ecosystems in the original channel of the Yellow River was explored in this paper.The results indicate that the development of agroforestry ecosystems can provide some economic and ecological benefits for local people.According to the natural and social conditions of the study area,several categories of agroforestry ecosystems can be developed in the original channel of the Yellow River in the east of Henan province: ① the pattern of forestry interplanted with crops(such as wheat) during the sapling period;② the pattern of forestry interplanted with medical plants after the age of trees is above 4 years;and ③ the pattern of forestry interplanted with home animals after the canopy of forest is closed.
