基于CVOR模型的阿巴嘎旗北部牧户草场健康现状研究

Health Status of Pastures in Northern Abaga Banner Based on CVOR Model

为客观评估阿巴嘎旗北部牧户草场健康程度现状,本研究采用CVOR模型对该地区北部的4个牧户和1个封育草场进行草场健康程度评价。结果发现研究区内牧户草场出现健康(牧户NR和封育草场FB)、亚健康(牧户AL和牧户CG)、警戒(牧户BL)三个层级,牧户健康现状差异主要体现在植物群落上。牧户间草场健康差异显著可能与定居放牧以来,牧户对草场的管理水平差异有关。禁牧休牧是短期调节牧区人地关系的手段之一,但不是根本之策。牧区人地关系和谐可持续发展研究仍然任重道远。

In order to objectively evaluate the current status of pasture health of herdsmen in the north of Abaga Banner, CVOR model was used to evaluate the pasture health of four herdsmen and one fenced pasture in the north of Abaga Banner. The results showed that there were three health levels: healthy(NR and fenced pasture FB), sub-healthy(AL and CG), and alert(BL), and the differences in the health status of pastoral households were mainly reflected in plant communities. The significant difference in pasture health among herders may be related to the difference in management level of herders since settlement grazing. Banning grazing and resting grazing is one of the means to adjust the relationship between man and land in pastoral areas in a short time, but it is not the fundamental policy. There is still a long way to go to study the harmonious and sustainable development of man-land relationship in pastoral areas.
