- 摘要:
- 经过对希拉穆仁草原围封、自由放牧草地及旅游区进行实地调查，结合内蒙古自治区第5次荒漠化和沙化监测实施细则，根据植被盖度和生物量等指标对草原进行了退化诊断与评价，并在此基础上研究了不同退化程度的地表粗粒组成。结果表明：希拉穆仁草原围封草地以轻度退化为主，自由放牧区以中度退化为主，但在坡顶出现重度退化，旅游区退化程度最为严重，均为重度退化区；可以以土壤颗粒 > 0.84 mm的百分比含量作为草原退化的判别标准，当其含量在82.22%～89.04%范围内为重度退化，含量在74.01%～79.53%为中度退化，含量在56.05%～66.11%为轻度退化。该指标能够直观、实时地反映草原的退化状况，且具有简便、快速诊断的生产应用性。
- Abstract:
- Fenced grassland, open grazing grassland and tourism areas in Xilamuren Grassland were surveyed combining with the Fifth Desertification and Desertification Monitoring Implementation Details of Inner Mongolia Autonomous Region, grassland degradation was diagnosed and evaluated according to indicators such as vegetation cover and biomass. Based on this, characterization of surface coarse particles of different degrees of degradation was studied. The results showed that the fenced grassland was mainly mild degraded; open grazing grasslands were mainly moderately degraded, but the top of the hill was severely degraded. Degradation degree at tourism areas was the most serious degraded. Volume percentage of non-erodible particles(> 0.84 mm) could be used as an appropriate discrimination standard to evaluate the grassland degradation degree, it is severe degradation when its content is 82.22%～89.04%, moderately degraded with its content of 74.01%～79.53%, mild degraded with its content of 56.05%～66.11%. The index may intuitively and real-time reflect the degradation situations of grassland, and it is also a simple, rapid diagnostic application to the practice.
