干旱河谷地区海拔高、沟壑深,年均降雨量在500毫米左右,天然牧草低矮稀疏、可食部分少。农户有传统的养羊习惯,但存栏率高出栏率低,经济效益不显著。而人为的过度放牧、滥伐和开采,加速了天然草场的退化,生态环境变的十分脆弱。本文阐述了缓解人畜与生态环境的矛盾,除科学规划有序开发外,推行种草养羊舍饲圈养是保护生态环境、实现可持续发展,促进农民增收的一条重要途径。
The arid valleys are high in elevation and deep in gullies with annual rainfall of about 500 millimeters. Natural grasses have low sparseness and few edible parts. Farmers have the traditional sheep husbandry habits, but the high rate of the pen out of the pen, economic benefits are not significant. However, man-made overgrazing, deforestation and exploitation have accelerated the degradation of natural pastures and the ecological environment has become very fragile. This article elaborates the eases of alleviating the contradiction between human beings and livestock and the ecological environment. In addition to the scientific and orderly development, the introduction of grass-raising and sheep-feeding is an important way to protect the ecological environment, achieve sustainable development and increase farmers’ incomes.
