半荒漠地区天然草场类型图的编制及载畜量估算——以内蒙古伊克昭盟公卡汉苏木为例

Compilation of the Map of the Type of Natural Grassland and the Calculation of Its Carrying Capacity in Semi-desert Area

本文以内蒙古伊克昭盟公卡汉苏木为例,论述了半荒漠地区的草场特征,基本类型,利用现状,分布规律等;并以现场调绘的航空相片为基础,编制了草场大比例尺的类型图;量算了草场面积,估算了草场载畜量,证实了该区草场已经过牧;提出了草场改良利用的建议和整治以及草场沙漠化的措施;对该区草场建设和制定畜牧业发展规划具有一定的参考价值和指导意义。

Based on aerial photographs, large scale topographic maps, detailed ground surveys and measurements of production of the rangelands, the characteristic features, main types, status of utilization and distribution of the rangelands in the Gongcharhan Commune, Ih Ju League, Inner Mongolia, were analysed, The results showed that most of the rangelands have been overgrazed and desertified. Some measures for rehabilitating the desertified rangelands have been presented.
