| 摘 要： | 目的]明确内蒙古荒漠草原生态系统的结构和功能的变化情况。方法]选定达茂旗为研究对象,运用3S技术,对草地植被覆盖度、草地生产力和载畜量30多年的变化进行了研究。结果]达茂旗草地植被覆盖度相比2000年初期升高了2百分点;达茂旗草地生产力由南向北呈递减趋势,相比2003年有所升高;达茂旗草地载畜量相比20世纪80年代和2000年初期整体水平有所升高。结论]该研究结果为内蒙古制定生态管理决策提供了理论依据。

| Abstract: | Objective] The aim was to accurately and truly reflect the changes in structure and function of the desert steppe ecosystem in Inner Mongolia. Method] The desert steppe in Damao Banner was taken as the object of study,the change of vegetation coverage,grassland produc-tivity and carrying capacity in recent more than 30 years was studied by using 3S technology. Result] The coverage of grassland vegetation in Damao Banner was increased by 2% compared with in the initial period of 2000;the productivity of grassland in Damao Banner decreased from south to north,which was higher than that in 2003;the carrying capacity of Damao Banner grassland was increasing compared with the 1980s and in the initial period of 2000. Conclusion] The result provides theoretical basis for Inner Mongolia to make up ecological management decision. |
