摘要

由于气候变化、人为因素、缺乏足够的环境和牧场政策、减灾战略以及良好的管理,贝尔低地的牧场资源已经退化。该研究利用基于gis的多标准决策分析和遥感技术确定了贝尔低地适合牛、羊、山羊和骆驼生产的牧场。利用土地利用和土地覆盖、降雨量、水分可达性、坡度和土壤类型进行适宜性分析。研究表明,牛、羊、山羊和骆驼的适宜养殖面积分别为4112、16311、6643和9820 km2。研究结果还表明,牛、羊、山羊和骆驼的适宜养殖面积分别为40099、30925、41981和36802 km2。另外,牛、羊、山羊和骆驼的适宜养殖面积分别为7644、4671、3630和5632 km2。另一方面,牛和羊的适宜养殖面积分别为399 km2和346 km2。该研究对提高畜牧业生产和减轻传统牲畜流动性对当地社区的影响具有重要意义。该研究还可以为政府当局制定环境和牧场政策提供见解,以确定牧场类型并为每种牲畜类别划分牧场。

Identification of Suitable Land for Livestock Production Using GIS-Based Multicriteria Decision Analysis and Remote Sensing in the Bale Lowlands, Ethiopia
Rangeland resources of the Bale lowlands have been degraded due to climate change, human factors, lack of sufficient environmental and rangeland policies, disaster mitigation strategies, and good management. The study identified suitable rangeland for cattle, sheep, goat, and camel production in the Bale lowlands using GIS-Based Multicriteria Decision Analysis and remote sensing techniques. Land-use and land-cover, rainfall, water accessibility, slope, and soil types were used for the suitability analysis. The study showed that an area of 4112, 16311, 6643, and 9820 km2 was highly suitable for cattle, sheep, goats, and camels, respectively. The results of the study also indicated that an area of 40099, 30925, 41981, and 36802 km2 was moderately suitable for cattle, sheep, goats, and camels, respectively. In addition, an area of 7644, 4671, 3630, and 5632 km2 was marginally suitable for cattle, sheep, goats, and camels, respectively. On the other hand, an area of 399 and 346 km2 was not suitable for cattle and sheep, respectively. The study is important for improving livestock production and mitigating the impacts of traditional livestock mobility on local communities. The study can also provide insights for government authorities to formulate environmental and rangeland policies to identify rangeland types and separate the rangeland for each livestock category.

期刊介绍: The main aim of the International Journal of Ecology & Development (IJED) is to publish refereed, well-written original research articles, and studies that describe the latest research and developments in ecology and development. It also covers the many potential applications and connections to other areas of Ecological Science, economics and technology such as the use and development of mathematics/statistics in ecology or use and development of economics for ecology & development or inter-disciplinary nature of applications for Ecology & Development. International Journal of Ecology and Development is published three issues in a year in Winter, Summer and Fall.
