摘要现阶段,我们国家大力发展农业,而且是大力提倡发展生态农业,比如梨地养鸡,鱼林模式等等生态农业这样既能节约成本,提高生产性能。本实验通过研究林地养鸡对于植物多样性的影响来说明鸡对植物多样性影响的大小,主要选择的是个体户自然状态在放养鸡。排除自然因素还有人为因素的影响,结果如下:只要合理根据林地的大小,合理控制鸡的数量,那么林地养鸡就对植物的种类影响比较小,林地会降低植物的数量,所以只要合理养殖,林地养鸡就是一种非常生态的养殖。51004

Woodland Chickens for the Influence of Plant Diversity
Abstract
At this stage, our country vigorously develop agriculture, but also to promote the development of ecological agriculture, such as chicken, fish, forest, and so on, such as ecological agriculture can save costs and improve production performance. This experiment through the research of forest chicken for the effects of plant persity to illustrate the chicken of the effect size of plant persity, mainly is self-employed natural state in free range chicken. Exclusion of natural factors and human factors of influence, results are as follows: as long as a reasonable according to the size of the woodland, the number of reasonable control of chicken, so chicken woodland will impact on plant species is relatively small woodland will decrease plant number, so as long as the reasonable farming, forest farm is a kind of ecological is very cultured.

绪论
农业的科学发展至关重要,当然这就需要强大的科学理论基础作为支撑。由此一些国家和地区趋于向传统模式回归,也就是发展可持续的生态农业,生态畜牧业作为可持续生态农业的一种农作模式,将会成为现在和将来的主要发展模式,其意义不言而遇。
