摘要
草地地上生物量是计算草地载畜量、生态评估及生态系统碳循环研究中的重要指标,实现对草地生物量及时、准确的监测,对于草地的合理利用具有重要意义。为了解当下草地生物量监测技术的研究和进展,以现有文献为基础,梳理了关于草地地上生物量测量方面的研究文献,将其概况为破坏性测量和非破坏性测量两大类方法;总结了非破坏性测量各类方法的优缺点;指出当下草地生物量的监测手段有待进一步探索发展,以满足现实草地监测的需要。
Grassland above-ground biomass is an important parameter in the calculation of grassland livestock carrying capacity, ecological assessment and ecosystem carbon cycle. The timely and accurate monitoring of grassland biomass is of great significance for the rational utilization of grassland. In order to understand the current research and progress of grassland biomass monitoring technology, based on the existing literature, we sorted the literature on grassland above-ground biomass measurement, and summarized it into such two large methods as destructive measurement and non-destructive measurement. The advantages and disadvantages of various non-destructive methods were summarized, and it was concluded that the current grassland biomass monitoring methods should be further explored and developed to meet the needs of real grassland monitoring.
