草原围栏是保护和建设草原的一项重要措施,是发展现代化草原畜牧业的基本建设和基础,许多国家已搞多年,我国近几年也在大力推广这项措施并收到了良好效果。为了适应草原建设的需要,准确地计算草原围栏的周长,根据多年生产实践的探索,现将不同面积的正方形、长方形草原围栏周长的计算公式分述如下: Grassland fences are an important measure for the protection and construction of grasslands. They are the basic construction and foundation for the development of a modern pastoral animal husbandry. Many countries have been engaged for many years. China has also vigorously promoted this measure in recent years and has received good results. In order to meet the needs of grassland construction, the perimeter of the grassland fence is accurately calculated. Based on the exploration of many years of production practices, the calculation formulas for the perimeters of square and rectangular grassland fences in different areas are now described as follows:
