豫西黄土丘陵区果、草、牧生态模式研究初报

Preliminary Report of the Research of Ecological Pattern of Fruits, Grass, Animal Husbandry Unite in the Loess Hilly Country of West Henan

豫西黄土丘陵区果园面积达 1 6万 hm2 ,土壤有机质缺乏 ,果品产量和质量逐年下降 ;大中型畜牧场污染严重 ,主要污染地表水、地下水、农田和空气 ;水土严重流失。针对这些问题 ,运用生态学原理和系统分析方法 ,因地制宜设计了三种果、草、牧结合生态模式 。

There are a large area of fruit orchards in the loess hilly country of west Henan Their fruits qualities and quantities are decreasing year by year because of lacking organic in the soil On the other hand, there are many big or middle animal husbandry farm in that district, which caused heavy pollution They mainly pollute the water, farmland and atmosphere And it's also has the problem of soil erosion To deal with these problems, we use the principle of ecology and the method of systematic analysis, combined with the actual condition, designed an ecological pattern of fruits, grass and animal husbandry unite, is having gotten some achievements \;
