Suitability Zoning and Layout Optimization of Forages in Uxin Banner Surrounded by the Mu Us Sandy Land in China

Abstract

The Mu Us Sandy land is one of the four largest sandy lands in China and the main sources of sand dust in the Beijing-Tianjin area. Uxin Banner, located at the southernmost end of Inner Mongolia Autonomous Region, is surrounded by this sandy land. Nearly one third of the Mu Us sandy land is located in Uxin Banner. Irrational expansion of agricultural land, unordered layout and overgrazing have resulted in the degradation of grassland, which leads to serious ecological problems and makes this area one of the five typical ecological fragile zones in China. Previous studies mostly focused on regional resource carrying capacity and man-land relationship, but few studies were conducted on how to select excellent varieties which are suitable for local resource and environmental background conditions to promote the healthy development of herbage industry. The research methods and conclusions of this paper can make up for this deficiency. Based on GIS and SPSSAU data scientific analysis platform, this paper uses multi-source remote sensing, statistics, surveys and other data to study the suitability zoning of silage planting, comprehensive evaluation of forage varieties, pastoral area industrial planning, etc. The research conclusions and suggestions can promote a high-quality development of agriculture and animal husbandry in Uxin Banner, help farmers and herdsmen to increase income, and provide scientific support for rural revitalization in the new period.
