林地养鸡对昆虫和土壤动物多样性的影响

摘要近几年，随着人们的生活质量提高，对肉鸡和鸡蛋的需求也逐步增加，越来越多的养殖户开始饲养肉鸡和蛋鸡。由于山地放养相对简单方便，不少养殖户便利用山地的便利进行肉鸡和蛋鸡的饲养。为保护物种多样性，合理利用林地资源，合理提高饲养效率，对于弄清林地养鸡对小动物多样性的影响具有重要意义。本文以牛头山为实验场所，分别在距离中心区域50m、100m、150m的三个不同方向，利用样方法测定区域内小动物的种类和数量，以及分布概况，并进行了相关分析。实验结果如下：1.鸡群对小动物的多样性有重大影响。2.鸡群活动频繁的区域小动物多样性小，活动不频繁的区域小动物多样性较多。3.较陡峭的山地会减少鸡群的活动。4.人类的生活垃圾严重影响物种的多样性。50721

Effects of the Chickens in the Woodland on the Diversities of Insects and Soil Animals

Abstract In recent years, with the improvement of people's quality of life, the demand for chicken and eggs has gradually increased, more and more farmers began to raise chickens and hens. Because the mountain range is relatively simple and convenient, many farmers will use the convenience of the mountain for broiler and laying hens. In order to protect the species persity, utilize the forest resources reasonably and improve the feeding efficiency, it is important to make clear the effect of the chicken raising on the persity of small animals. The Jiangsu Normal University of Quanshan campus Niutoushan experimental sites, respectively in three different directions from the center of the regional 50m, 100m, 150m, with sampling method for the determination of the type and quantity of regional small animals, and general distribution and correlation analysis. The results are as follows: 1. The chickens have a great influence on the persity of small animals. 2. The activities of the chicken group were frequent in the area of small animal persity, activities are not frequent in the area of small animal persity. 3. The more steep mountains will reduce the activities of the chicken group. 4. Human life waste seriously affect the persity of species.
